Show up at a gravel event, and you’d be forgiven for thinking you were transported back into the late 1980s. Gravel riding offers a bit of roll-your-own style, but these types of races and rides favor light weight over bump absorption, so most opt to leave the suspension at home.
This resurgence of rigid bike riding has borne a variety of ways to reduce the chatter and impact of these less-than-smooth surfaces. Whether it’s an undamped carbon leaf spring, a shortened version of a telescopic suspension fork, or simply stuffing the biggest tire possible into a bike frame, everyone’s looking to take the edge off. That’s what we set out to solve with the Reserve 650b rims.
The 650b rim (which is the same as 27.5” if the alphanumeric soup has you a bit spun) profile looks more like our other Reserve offerings, largely because the needs of a 2.0” tire and a 2.3” tire aren’t as dramatically different as those of a 30mm tire. It’s still a fairly low-profile, 24-hole rim that’s been tuned the same way as the 700c rim, and at 25mm wide, it’ll work with tires from 40mm wide to about 53mm wide, or 2.1 inches.
The wheelset uses Sapim CX Ray bladed spokes for a bit of extra compliance (and a tiny bit of aerodynamic gain!), and are available with DT Swiss’ venerable 350 hubs, or with Industry 9’s Torch Road hubs.
