Jean Beyl, lying in a hospital bed in the French Alps, conceived a ski binding that would release before your bones did. It was the kind of pragmatic engineering insight that would define Look for the next seven decades: identify a mechanical problem, solve it with precision, then move on to the next impossible thing.</p>https://derailleur.ch/bikes/allcity-spacehorse/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/allcity-spacehorse/<p>The Space Horse is All-City&rsquo;s answer to a question many riders are asking: What if we built a steel gravel bike without apology? Not a road bike with clearance bolted on, but a true all-roader that handles loaded touring, technical singletrack, and long gravel miles with equal composure.</p> <p>The 612 Select CroMoly tubing is the heart of it. Named after Minneapolis&rsquo;s 612 area code, this double-butted chromoly keeps the suppleness that made steel legendary while shaving grams where it matters. The result is a frame that feels light and responsive beneath you—atypical for a steel touring bike—yet possesses that unmistakable steel compliance when the road roughens. The champagne shimmer finish catches light in unexpected ways, shifting between muted gold and pale green depending on the angle and time of day.</p>https://derailleur.ch/bikes/colnago-c40/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/colnago-c40/<p>The Colnago C40 is not just a bike. It&rsquo;s a document of the moment when professional cycling discovered that carbon fiber could define an entire era.</p> <p>This is a first-generation C40 from 1996 or 1997, wearing the original Team Olympus paint job—a scheme as iconic as any in cycling history. Black base with electric blue and white accents, the livery announces itself with the confidence of a frame that knows what it is: a thoroughbred race machine. The glossy carbon finish, still shining beneath years of careful handling, reveals the care taken in its construction.</p>https://derailleur.ch/bikes/colnago-master/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/colnago-master/<p>The Colnago Master occupies a singular place in cycling history. It&rsquo;s the bike that proved steel could be sculpted into something extraordinary—that tubing could be profiled, crimped, and shaped to achieve properties that seemed impossible.</p> <p>Columbus tubing, drawn from the Milanese foundry that defined an era of Italian cycling, makes up the frame. The signature star-shaped tube cross-section catches light in geometric patterns, a visual reminder that this isn&rsquo;t standard round tubing. That profile does something remarkable to the ride: it confers exceptional torsional stiffness—meaning the frame resists twisting when you stomp on the pedals—while the relatively thin walls preserve the suppleness and vertical compliance that made steel legendary among those who truly understand the material.</p>https://derailleur.ch/bikes/genesis-volare/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/genesis-volare/<p>Reynolds 931. The name alone carries weight among those who understand the cutting edge of steel engineering. This maraging stainless steel—developed using aerospace metallurgy—occupies a rarefied position: it&rsquo;s as light and strong as titanium, yet adds complete corrosion resistance and a responsive ride quality that titanium can&rsquo;t quite replicate. Genesis restricts 931 builds to a small number of approved framebuilders. This Volare is one of them.</p> <p>At 2.41 kilograms, the frame is remarkably light for a steel bike—and impossibly light for one built from a stainless alloy. This is a bike designed for riders who understand that steel, built thoughtfully, doesn&rsquo;t need to be heavy. The geometry is contemporary and playful: modern racing position, modern stiffness, modern braking (flat-mount disc), yet with the ride quality that only steel delivers. Silver with a black fork strikes a minimalist pose, letting the engineering do the talking.</p>https://derailleur.ch/bikes/klein-quantum-race/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/klein-quantum-race/<p>Gary Klein changed everything when he convinced the cycling world that aluminum wasn&rsquo;t supposed to be harsh and unforgiving. Large-diameter, thin-walled tubes, he proved, could deliver something unexpected: stiffness that comes from geometry and engineering rather than material density, combined with a responsive, direct feel that riders loved. The Quantum Race, from the early 2000s, is a direct descendant of that vision.</p> <p>The silver gradient finish is pure Klein—a nod to the brand&rsquo;s obsessive attention to aesthetics and to its era, when American race bikes wore bold colors and didn&rsquo;t apologize for it. The TIG-welded aluminum frame is responsive and lively, the kind of bike that rewards smooth pedaling and punishes sloppiness with immediate feedback. A carbon fork softens the edge just enough, adding compliance without sacrificing steering precision.</p>https://derailleur.ch/bikes/look-795-light/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/look-795-light/<p>Look&rsquo;s 795 Light is what happens when French engineers decide that 7.6 kilograms isn&rsquo;t quite light enough—so they rethink everything. The 1.5k carbon weave (1.5k filaments per tow, compared to the industry-standard 3k or 12k) allows for impossibly thin laminate walls and NACA-profiled tubes that are both lighter and more aerodynamically sculpted than anything else in its class. The frame is a whisper in your hands.</p> <p>The engineering goes deep. The ZED2 integrated carbon crankset eliminates the interface between arm and spindle, saving grams and stiffening the drivetrain. The E-Post 2 carbon seatpost houses the Di2 battery internally, meaning there&rsquo;s zero cable clutter, zero mechanical complexity. The AeroStem adjusts its angle without requiring a tool, adapting the riding position to wind and terrain. Every component serves the singular goal of weight and aerodynamic efficiency.</p>https://derailleur.ch/bikes/look-kg-361/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/look-kg-361/<p>The KG-361 is a milestone machine—a Look frameset from that pivotal moment at the turn of the millennium when carbon fiber technology had matured enough to deliver frames that rode beautifully, not just light. The Carbon HR tubes, manufactured using Look&rsquo;s proprietary resin-transfer process in their Nevers factory, set the benchmark for carbon road bikes during that era.</p> <p>Black with white decals, the frame exudes understated confidence. This was a bike built for someone who cared about performance above aesthetics, yet Look&rsquo;s French sensibility meant the two never conflicted. The Pro Series specification means this wasn&rsquo;t a budget frameset—it was built to the standards demanded by professional riders. FSA Orbit headset, removable rear dropout, carbon seatpost—every detail was considered.</p>https://derailleur.ch/bikes/mason-exposure/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/mason-exposure/<p>The Mason Exposure is a bike designed for riders who think in terms of continents, not kilometers. An award-winning adventure touring frame built in collaboration with Italian builders Cicli Barco, it represents a deep understanding of what makes steel the perfect material for long-distance travel: durability, repairability, and a ride quality that softens the blows of thousands of kilometers of rough roads.</p> <p>The Dedacciai Zero Uno tubing is progressively butted—thinner at the middle of each tube, thicker at the joints—so the frame feels light without being fragile. Pair that with Reynolds 631 steel in select tubes, and you get a chassis that can handle fully laden bikepacking (the frame supports 650B x 58mm or 700c x 50mm tires, roughly 2.4 to 2 inches) without feeling sluggish or dead.</p>https://derailleur.ch/bikes/nevi-grimsel/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/nevi-grimsel/<p>Nevi, the Italian titanium specialist based in Bergamo, builds frames for riders who understand that some materials simply transcend the categories we impose on them. The Grimsel is a meditation on what Grade 9 titanium can achieve when a framebuilder treats it with the respect it deserves.</p> <p>Grade 9 (3AL-2.5V) titanium is the sweet spot of the periodic table. Stronger than commercially pure titanium, yet more workable than the aerospace-grade 6AL-4V, it offers something rare: a material that&rsquo;s simultaneously strong, light, and supremely rideable. Cold-drawn tubing amplifies these qualities, delivering a frame that feels alive beneath you—responsive to input without being harsh, supple enough to soak up vibration yet stiff enough to respond to power.</p>https://derailleur.ch/bikes/open-up-rapha-limited-edition/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/open-up-rapha-limited-edition/<p>The Open U.P. is a frame that changed how cyclists think about categorization. When designer Andy Kessler set out to create &ldquo;Unlimited Possibilities,&rdquo; he rejected the idea that a bike had to be either a road racer or a gravel explorer—it had to choose. The U.P. chose both. Road geometry—aggressive, tight, designed for speed—paired with tire clearance for 2.1-inch mountain bike tires. One frame. Infinite riding.</p> <p>This limited edition collaboration with Rapha Cycling Club is special: dark navy with rose pink accents, a livery that feels sophisticated without being ostentatious. The carbon construction is ultra-efficient, with tube shaping optimized for the unique stresses a road-geometry gravel bike endures. Continuous seattube, BB386EVO pressfit, Smartmount disc brakes—these are details that speak to careful engineering. At 1040 grams, the frame is lightweight enough to feel lively on pavement, yet stiff enough to handle gravel and light singletrack.</p>https://derailleur.ch/bikes/principia-rex-pro/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/principia-rex-pro/<p>Principia didn&rsquo;t need to whisper. During the 1990s and 2000s, the Danish manufacturer announced itself loudly through pure performance: razor-sharp aluminum race frames that had no apologies and no compromise. The Rex Pro, at just 1,140 grams, made a categorical statement—that large-diameter, robotically welded aluminum could match carbon&rsquo;s weight while delivering a direct, responsive ride that carbon couldn&rsquo;t quite replicate.</p> <p>In black with silver decals, the Rex Pro embodies Danish restraint and engineering precision. The aluminum frame is stiff—aggressively so. This isn&rsquo;t a bike for the faint of heart or the unpracticed pedaler. It rewards smooth, powerful strokes and punishes inefficiency with immediate, unfiltered feedback. Paired with a Mizuno carbon fork, it&rsquo;s a machine built for riders who understand that responsiveness and engagement matter more than compliance.</p>https://derailleur.ch/bikes/ritchey-swisscross-v2/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/ritchey-swisscross-v2/<p>Tom Ritchey has spent four decades proving that steel, when treated with discipline and respect, can match or exceed the weight and performance of materials that came after it. Ritchey Logic—his proprietary triple-butted steel alloy, heat-treated after welding for consistent hardness—is the proof. The SwissCross V2, at just under two kilograms for the frame, is a masterclass in what&rsquo;s possible when engineering meets craft.</p> <p>The beauty of Ritchey Logic is subtle but profound: the tubing is light where it can be, strong where it must be. The frame resists the temptation toward radical geometry; instead, it pursues something more timeless—proportions that work across disciplines. Cyclocross, gravel, even road riding: the SwissCross adapts. Tire clearance for 700x40c, 12mm thru-axle rear spacing, flat-mount disc brakes—these are contemporary standards executed with a builder&rsquo;s precision.</p>https://derailleur.ch/bikes/ritte-phantom/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/ritte-phantom/<p>The Ritte Phantom was designed by Tom Kellogg—a UCI World Championship-winning framebuilder—to answer a specific question: What if we built an all-road bike with the precision and intention of a race machine? The answer is this: elegant, silky, and potent all at once.</p> <p>Reynolds 725 is the material that makes it possible. This chromoly steel, heat-treated after welding rather than before, allows the builder to shape tubes while the material is still workable, then harden it to a tensile strength of 900 MPa. It bridges the gap between classic steel and exotic materials, offering a ride quality that&rsquo;s responsive and lively without the brittleness that can come with over-hardened alloys. Silver with light blue accents, the Phantom announces itself with understated sophistication—a Los Angeles brand with European sensibilities.</p>https://derailleur.ch/bikes/standert-erdgeschoss/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/standert-erdgeschoss/<p>There is something distinctly Berlin about the Standert Erdgeschoss. Designed in Berlin, handmade in Taiwan with meticulous attention to detail—it&rsquo;s a bike that speaks to clean aesthetics, authentic craft, and a philosophy that rejects mass production entirely.</p> <p>The material is stainless steel, which means this is a frame designed to outlive its owner. Stainless trades a small weight penalty (10 kilograms complete) for near-total corrosion resistance and a distinctive aesthetic that requires no paint. The Rawkim colourway—half raw, half painted—reveals the stainless steel in its natural state on one side, a subtle chrome-grey that catches light in unexpected ways. It&rsquo;s a statement about material honesty: here is the frame in its truth.</p>https://derailleur.ch/bikes/stelbel-strada-oria/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/stelbel-strada-oria/<p>This is a Stelbel Strada from roughly 1989, built with Oria&rsquo;s visionary star-shaped tubing. It&rsquo;s a piece of cycling history that bridges two eras: the end of the pure steel age and the beginning of aerodynamic thinking in frame design. When Stelio Belletti patented his TIG welding technique in Italy, he opened possibilities that previous framebuilders could only imagine.</p> <p>Oria tubing, manufactured in Bergamo, was genuinely radical. The signature star cross-section doesn&rsquo;t just look different—it fundamentally changes how the frame behaves. The points of the star increase torsional rigidity (resisting twist under power), while the overall shape offers aerodynamic advantages without requiring the weight penalty of round tubes. In 1989, this was avant-garde engineering. The Polish national team won gold at the 1975 Mettet world championships on Stelbel bikes—this is a heritage machine.</p>https://derailleur.ch/bikes/veloheld-iconx-ti/Sun, 05 Apr 2026 00:00:00 +0000https://derailleur.ch/bikes/veloheld-iconx-ti/<p>Veloheld, the German manufacturer based in Dresden with production in Leipzig, understands that titanium isn&rsquo;t about weight—it&rsquo;s about character. The IconX is a gravel and all-road frame built from TiAl3V2.5 (Grade 9) titanium, which adds aluminum and vanadium to boost strength while preserving titanium&rsquo;s natural corrosion resistance and vibration damping. The result is a material that rides like nothing else: alive, smooth, and virtually indestructible.</p> <p>At roughly nine to nine-and-a-half kilograms complete, the IconX isn&rsquo;t featherweight, but the weight is allocated with purpose. The frame tips the scales at just 1.5 kilograms, with a 565-gram carbon fork adding stiffness without bulk. This is a bike designed for long miles over mixed terrain—the kind of riding that separates materials and builders. Titanium doesn&rsquo;t fatigue. It doesn&rsquo;t crack under repeated stress. It rides better the more you use it, as the rider and machine develop a relationship measured in years or decades.</p>https://derailleur.ch/journal/campagnolo-record-through-the-ages/Sun, 15 Mar 2026 00:00:00 +0000https://derailleur.ch/journal/campagnolo-record-through-the-ages/<p>There&rsquo;s something quietly magnificent about holding a Record component from 1995 and comparing it to one from 2020. Both are unmistakably Campagnolo — that particular shade of anodized aluminum, the mechanical precision that feels almost delicate — yet the span of innovation between them is staggering. Tullio Campagnolo founded his company in Vicenza in 1933, a city already renowned for metalworking, and the philosophy he embedded there has proven remarkably durable: mechanical precision as a kind of faith, each component an argument that engineering excellence needs no embellishment.</p>https://derailleur.ch/journal/campagnolo-ekar-gravel-experiment/Sun, 01 Mar 2026 00:00:00 +0000https://derailleur.ch/journal/campagnolo-ekar-gravel-experiment/<p>When Campagnolo announced Ekar in 2021, there was a moment of collective silence in the cycling community. Not scepticism, exactly — more like confusion. A 13-speed groupset? From Campagnolo, the company that had spent seventy years refining the art of road cycling components? A single chainring, no front derailleur? What were they doing?</p> <p>The answer, as I&rsquo;ve come to understand through living with five Ekar-equipped bikes in my collection, is that they were asking a different question entirely. Not &ldquo;how do we adapt our road groupset for gravel?&rdquo; but &ldquo;what would a gravel groupset look like if we designed it from first principles?&rdquo;</p>https://derailleur.ch/journal/steel-versus-titanium/Sun, 15 Feb 2026 00:00:00 +0000https://derailleur.ch/journal/steel-versus-titanium/<p>Ask a cyclist to name the great material debate and he will usually say steel versus carbon, as if the whole history of the bicycle were compressed into that one contemporary argument. I understand why. Carbon dominates the present tense. But in my own orbit the quieter and more revealing tension lies elsewhere, between steel and titanium. They are often presented as alternatives, as if one must cancel the other out, yet in practice they belong to a similar moral world. Both ask to be taken seriously. Both reward patience. Both still make sense when fashion has moved on.</p>https://derailleur.ch/journal/brooks-saddles-patina-of-miles/Sun, 01 Feb 2026 00:00:00 +0000https://derailleur.ch/journal/brooks-saddles-patina-of-miles/<p>A Brooks saddle, fresh from the box, is notoriously uncomfortable. The leather is stiff, unbending, almost hostile to the rider. This is by design — a fact that separates Brooks from every other saddle manufacturer and explains why cyclists either become devout believers or sceptical outsiders. There is no middle ground with Brooks. The commitment is total, or it&rsquo;s nothing.</p> <p>Most of my collection rides on Brooks. Not by accident, but because their philosophy aligns with the bikes they&rsquo;re mounted on: built for the long term, improving with use, asking the rider to invest in the relationship.</p>https://derailleur.ch/journal/italian-framebuilders-colnago-stelbel-nevi/Thu, 15 Jan 2026 00:00:00 +0000https://derailleur.ch/journal/italian-framebuilders-colnago-stelbel-nevi/<p>There is a line that runs through Italian cycling like a seam in leather — visible if you look, invisible if you don&rsquo;t. It connects Ernesto Colnago&rsquo;s first frames in 1954 to Stelio Belletti&rsquo;s TIG-welded revolution in 1973 to Sergio Finazzi&rsquo;s titanium obsession in 1992. Three builders, three philosophies, three materials, one shared conviction: that a bicycle frame is not merely an engineering solution but an expression of its maker&rsquo;s understanding of what cycling should feel like.</p>https://derailleur.ch/journal/3t-components-form-follows-function/Thu, 01 Jan 2026 00:00:00 +0000https://derailleur.ch/journal/3t-components-form-follows-function/<p>There&rsquo;s a particular kind of elegance that comes from absolute commitment to solving a specific problem well. 3T — Tecnologia del Tubo Torino, as the Italian brand was originally known — has spent six decades pursuing that elegance from its workshops in Turin. In my collection, their components appear on nearly every bike, and what strikes me about each one is a quality I can only describe as inevitability. You look at a 3T stem and think: yes, of course it looks exactly like this. Not because it&rsquo;s particularly beautiful in a sculptural sense, but because every visible line appears to serve a function.</p>https://derailleur.ch/journal/klein-quantum-race-american-aluminium/Mon, 15 Dec 2025 00:00:00 +0000https://derailleur.ch/journal/klein-quantum-race-american-aluminium/<p>In 1973, while the Italian workshops of Colnago, De Rosa, and Masi were refining techniques that had served them for decades — brazing steel tubes into lugged joints, filing each connection by hand — a chemical engineering student at MIT was asking a different question entirely. Gary Klein wanted to know what would happen if you abandoned steel&rsquo;s comfortable traditions and built a bicycle frame from oversized aluminium tubes instead.</p>https://derailleur.ch/journal/why-reynolds-931-is-the-endgame/Mon, 01 Dec 2025 00:00:00 +0000https://derailleur.ch/journal/why-reynolds-931-is-the-endgame/<p>There&rsquo;s a particular kind of technical perfection that emerges when a material has been refined not for fashion or marketing, but for fundamental engineering reasons. Reynolds 931 represents that perfection — a maraging stainless steel tubing system so thoroughly optimised for the specific demands of bicycle frames that it&rsquo;s difficult to imagine meaningful improvement.</p> <p>My Genesis Volare 931 Disc, built with these tubes from Birmingham, is perhaps the clearest technical statement in my entire collection. It says: we have solved the fundamental problem. Everything else is variation.</p>
