The biggest cycling tech story of 2026 is not a new electronic drivetrain, lighter carbon frames, or another tweak to geometry. It\u2019s a wheel\u2014specifically, a much bigger one. After years of quiet prototyping, rumors, and one-off customs, 32-inch wheels are arriving in public view in multiple places all at once. They\u2019re showing up on prototype cross-country race bikes, on production-ready gravel grinders, and in the product plans of tire and suspension companies that usually don\u2019t make a move unless they believe a new category has real legs.<\/p>\n
Why 32\u201d Wheels Are a Big Deal<\/h2>\n
Over the past five or six years, mountain bike product development has largely shifted toward refinement rather than reinvention. Bikes have gotten better, but in smaller increments\u2014changes that often aren\u2019t enough to push riders to upgrade. You could argue that\u2019s even a good thing, at least for riders (myself included) who are tired of buying bikes that feel obsolete a season or two later. As someone who tests bikes for a living I\u2019ll put in plainly: If you invested in a new mountain bike back in 2020, it\u2019s still just as good, just as capable, as one you may be tempted to buy today. There\u2019s never been another period of time in my career when I would have said this.<\/p>\n
But 32-inch wheels are poised to disrupt this equilibrium, just like 29-inch wheels did two decades ago. Those bigger hoops replaced 26-inch wheels in nearly every mountain biking category. They rolled over obstacles with ease, carried more speed, and once geometry caught up, they handled better and gave riders more confidence.<\/p>\n
Can 32-inch wheels push the envelope even further? Or is this just the cycling industry\u2019s attempt to make the bikes we already own feel outdated\u2014a response to the post-pandemic whiplash that\u2019s left many bike brands searching for a reason to get riders buying again?<\/p>\n
The Performance Upshot<\/h2>\n
To understand how real this shift is, I spoke with engineers, product managers, and test riders across the industry\u2014from Fox, Trek, Maxxis, and Vittoria to smaller design firms and bike brands already working on production models. Some are still experimenting. Others are preparing to bring bikes to market. All of them are trying to answer the same question: where do 32-inch wheels actually make sense?<\/p>\n Right now, the clearest answer is cross-country, where efficiency gains matter most, and riders are willing to tolerate tradeoffs. Craig Richey, senior director of marketing and product strategy at Fox Factory, said the industry is already past the what-if stage. \u201cI think we\u2019re beyond the exploration phase now with 32 for XC,\u201d he said. After months of testing a 32-inch full-suspension XC bike, he came away impressed: \u201cThe amount of traction is unbelievable. Even on a very minimal tread XC tire, the grip is phenomenal. Roll-over speed is really good. You don\u2019t get hung up on little bumps.\u201d<\/p>\n What stood out more was how close that performance already is to today\u2019s race bikes. The prototype Richey has been riding since last summer is a heavy, aluminum early-stage test mule\u2014at least five pounds heavier than a modern carbon 29er. Even so, he said it carries essentially the same speed as a refined World Cup-level XC bike.<\/p>\n If cross-country is the obvious starting point, gravel may be the category with the broadest appeal. Ken Avery, senior VP of product development at Vittoria Tires, said the basic theory is already becoming clearer in testing: all else being equal, a larger wheel rolls more smoothly and may offer \u201ca few watts advantage\u201d in some cases, though he was careful to note that the company has not published its final test data. Avery also sees gravel as a potential sweet spot because the riding is less technical and rider fit is less restrictive than it is on mountain bikes. \u201cIn the big mile gravel events that are so common, I could certainly see this being something that\u2019s quite popular,\u201d he said.<\/p>\n Salsa is one of the brands leaning hardest into that idea. Its new Fargo 32 bikepacking model, which will be available to consumers this fall, is the first clear sign that 32-inch wheels may not stay confined to the race course. Salsa product manager Joe Meiser said the company\u2019s testing showed that the larger wheels roll faster and farther under the same amount of power, while also increasing the tire contact patch by roughly 10 to 15 percent. On loose surfaces, he said, the effect is immediately obvious: \u201cIt really doesn\u2019t flinch in the sand.\u201d The comparison Meiser keeps coming back to is the 26-to-29 shift. \u201c32 is to 29, 29 is to 26,\u201d he said.<\/p>\n If the benefits are that clear, the obvious question is why it took so long to get here.<\/p>\n The answer comes down to where the rubber meets the trail. Travis Brown, Trek\u2019s R&D field test manager and a former professional mountain bike racer who has worked on everything from early 29ers to mixed-wheel platforms, said brands have been experimenting with oversized wheels for years, but until recently, the industry lacked a proper, modern tire to enable serious comparative testing.<\/p>\n \u201cYou wouldn\u2019t think that the tire would be the bottleneck to discovery,\u201d said Brown. \u201cBut building frames is easy. Building rims is pretty easy. Suspension forks are a little bit more challenging, but everything is easier compared to getting tires made.\u201d<\/p>\n The issue isn\u2019t just design; it\u2019s a six-figure commitment. Developing a new tire size requires entirely new molds and curing equipment, and those aren\u2019t small investments. Unlike frames or rims, where brands can prototype quickly and iterate in-house or with smaller production runs, tires demand full-scale manufacturing from the start. Until recently, there wasn\u2019t enough confidence in 32-inch wheels to justify that level of investment.<\/p>\n That shift needed a catalyst. Duncan McGuire, sports marketing and athlete manager at Maxxis, said the company\u2019s 32-inch program began because race teams were asking for an edge ahead of the 2024 Paris Olympics. The original goal was to have a 32-inch version of Maxxis\u2019 fastest mountain bike tire, the Aspen, ready for those Games, but development timelines pushed that out. Now, instead of being unveiled for Paris, the category looks set to break out through this year\u2019s World Cup season and into 2027 and 2028 product cycles.<\/p>\n The next question was whether 32-inch wheels could work on smaller bikes. Much of the early conversation around 32-inch wheels has centered on taller riders, but Salsa pushed to see if that had to be the case. Allison Schmitz, a design engineer at Salsa and a 5\u20193\u2033 rider, helped develop a size small prototype after questioning whether it was even possible. \u201cIt might seem counterintuitive to make a small 32-inch bike, but I can confidently say that small riders can handle these larger wheels,\u201d she said.<\/p>\n In testing, Schmitz said the benefits were clear\u2014better rollover, traction, and momentum\u2014as were some trade-offs. \u201cAll those benefits come with the compromise of a slow start up\u2026 and on certain pavement climbs\u2026 I didn\u2019t necessarily feel the increased speed.\u201d<\/p>\n Other brands are seeing the trade-offs as well.<\/p>\n Julien Boulais, director of marketing and strategy at Faction Bike Studio<\/a>, a design and engineering firm that develops bikes for brands behind the scenes, said the opportunity is clear, but so are the limits. \u201cI\u2019d be surprised if 32-inch wheels take over as much of the industry as 29ers did,\u201d Boulais said, pointing to packaging challenges and the risk of brands forcing the wheel size into categories where it might not belong.<\/p>\n![\"Man](\"https:\/\/cdn.outsideonline.com\/wp-content\/uploads\/2026\/04\/Revel-Bikes-3222_Courtesy.jpg?width=3840&auto=webp&quality=75&fit=cover\"\/)
