Gravel

The Crux 5 launched today, and most of the coverage is focused on what it means for gravel racing. Fair enough — that’s what Specialized built it for. But I keep staring at the spec sheet thinking about a different question: at what point does a bike like this make a dedicated road bike redundant for most riders? I think we’re getting close. The Weight Argument Is Real The S-Works Crux 5 frame weighs 789 grams. The Tarmac SL8 frame — one of the lightest road frames ever made — weighs 685 grams. That’s a 104-gram difference. For context, that’s roughly the weight of a CO2 inflator and a folded tire. It’s real, but it’s not the kind of gap that changes your life on a Saturday morning ride. ...

Specialized dropped the Crux 5 today, and it’s a bigger departure than most people expected. The round tubes are gone. The cross-racing DNA is largely gone. What you’re left with is essentially a fat-tire Tarmac built to win at Unbound — and honestly, that’s probably the right call for where gravel racing is in 2026. From Cross Bike to Pure Gravel Weapon The original Crux was always a little weird in a good way. It came out of cyclocross, landed in gravel, and held onto that lightweight-above-all-else philosophy while the rest of the industry started chasing aerodynamics. For a while that positioning worked. But gravel racing has evolved considerably — races like Unbound reward sustained efficiency over 200 miles, tires have gotten bigger, and nearly every serious gravel brand has run their bikes through a wind tunnel by now. The Crux had to evolve or get left behind. ...

Let’s be honest: nobody should be surprised by the Crux 5. The moment gravel racing started generating real prize money, media deals, and WorldTour-level athlete contracts, the clock started ticking on the genre’s “just ride your bike” ethos. Aero gravel bikes were inevitable. The only question was who’d get there first and how far they’d go. Specialized went pretty far. The Purists Will Complain. They’re Also Wrong. Every time a bike category gets serious, the same conversation happens. Road cyclists complained when aero road bikes replaced round tubes. XC mountain bikers complained when 29ers replaced 26-inch wheels. Gravel riders are now complaining that the Crux 5 looks too much like a Tarmac. And just like those previous arguments, the complaints will fade once people start seeing finish times. ...

Scott just showed up to Unbound week with a 32-inch aero gravel prototype and two serious athletes ready to race it 200 miles across Kansas. Cameron Jones — last year’s Unbound winner and 2025 Lifetime Grand Prix overall — is aboard one. Robin Gemperle, who won the Tour Divide and Silk Road Mountain Race in 2025, is on the other. These aren’t marketing props. They’re race bikes. And here’s the thing: while the cycling world has been busy debating whether 32-inch wheels make sense for XC racing, Scott may have accidentally — or deliberately — made the strongest argument yet that gravel is where this wheel size actually belongs first. ...

If you’ve been shopping for a gravel bike recently — new or used — you’ve probably run into the term UDH and wondered whether it matters for what you’re building. The short answer is: it depends on what groupset you want to run. The longer answer is that a lot of popular gravel frames have had their dropouts quietly updated mid-generation, which means two bikes with the same name and similar looks can have very different futures when it comes to drivetrain compatibility. ...

If you’re shopping for a gravel bike and want to run SRAM’s 13-speed XPLR ecosystem — or just want the future-proofing that UDH brings — the first question is whether the frame you’re considering actually has it. We’ve pulled every gravel bike currently listed on SRAM’s official Bike Finder with the UDH filter applied, as of May 2026. A note before you use this list: This is sourced directly from SRAM’s Bike Finder tool and reflects only the bikes SRAM has listed there. It is not an exhaustive list of every UDH-compatible frame on the market — there are likely other frames from brands not represented in the Bike Finder, particularly smaller builders and direct-to-consumer brands, that also use the UDH standard. Always verify directly with the frame manufacturer before purchasing, especially on the used market where model year matters. ...

ENVE just dropped its new G SES gravel wheel lineup, and the headline spec is going to make a lot of people do a double-take: a 35mm internal rim width on the flagship 6.7 Pro. That’s wider than most mountain bike wheels from five years ago, on a gravel race wheelset. It’s a bold statement, and ENVE is clearly not interested in incremental. The range has three wheels: the G SES 4.5, the G SES 4.5 Pro, and the G SES 6.7 Pro. Here’s what separates them. ...

When Zipp launched the 303 XPLR SW in 2024 with a 32mm internal width, it felt like a line in the sand. Nobody had pushed a production gravel wheel that wide before, and the message was clear: the era of putting 45mm tires on 25mm rims was over. Now ENVE has responded with the G SES lineup — and specifically the 6.7 Pro at 35mm internal — and the aero gravel wheel market looks meaningfully different than it did twelve months ago. ...

If you’ve been paying attention to Canyon’s releases over the past year, there’s a pattern worth noting. The Aeroad CFR established the template — deep aero tubes, integrated cockpit, dropped seatstays, built purely for speed. Then last month the Endurace CFR showed up and took that same design language, added a little more tire clearance, and called it an endurance road bike. We actually covered that one here on Mizubikes. Now at The Traka in Girona this week, Canyon’s new team — the Canyon x DT Swiss All-Terrain Racing squad — showed up to race on what appears to be an unreleased Grail CFR, and it’s exactly what you’d expect if you’ve been following the thread: Aeroad DNA, pushed all the way into gravel. ...

The line between a gravel bike and a mountain bike has been blurring for years. But 2025 was the year it basically disappeared. At the Leadville Trail 100, two of the top three finishers in both the men’s and women’s races were on drop bar mountain bikes — full suspension included. Keegan Swenson won on a Santa Cruz Blur with drops. Melisa Rollins podiumed on a drop-bar Liv full suspension. Dylan Johnson, the godfather of the drop bar MTB experiment, showed up on an Unno Horn with a Fox suspension fork and GRX shifters. ...
