Gravel Bikes

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. ...

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. ...

If you’re shopping for your first gravel bike and trying to make sense of tire clearance specs, here’s the first thing to understand: the number on the spec sheet isn’t the full story. I recently tested this on the Specialized Crux. The stated max clearance is 47mm — but I mounted a 50c tire in the rear and a 2.1" up front to see what the frame could actually handle.
