24mm wide – This fits the 45-50mm tires perfectly, creating a secure interface and the ideal shape for tire to rim interface. Tire handling will be optimized.
36mm deep – With a nice aero profile and rim shape designed to help crosswind stability. Lots of the riding on gravel events takes place at speeds that still call for an aero benefit.
2.9mm offset rim – This helps with evening out the spoke tension for a more balanced wheel. The rim will face one direction for the front and the opposite direction for the rear, giving the best responsiveness and durability.
Tubeless hookless rim bed – The larger 650B tires are perfect to run tubeless for added protection when grinding on the rocks of a gnarly gravel road. The hookless rim allows for a wider internal width, and added strength (and impact protection) when riding over rocks. Increase your protection against flat tires, have the ability to run lower tire pressure for better handling by running the wheel tire combo tubeless.
430-gram rim weight – This feathery weight gives a nice lightweight wheelset (only 1550 grams for the set built on our Quest hubs). Accelerate and hold your speed with a great combination of weight, aero, and crosswind handling.

Designed for high volume 47mm tires
When we decided to develop a gravel specific wheelset, we knew we had to develop every aspect from the ground up. We didn’t just want to re-purpose a mtb wheelset or cyclocross wheelset that would work ok for gravel riding. When Boyd first started riding gravel, it was on a road bike with 25mm tires. Then a cyclocross bike was used with 28mm tires, then 32mm, 38mm, and eventually 40mm. Each time the tire size increased, the bike geometry and gear ratio changed. The traction was better, but the handling was worse.
Our gravel specific 650b wheelset, designed around a 47mm tire size. Gravel events take place at higher speeds and you are spending a lot of the time above 18mph. At those speeds, aero forces really come into play so we developed an aero 36mm deep rim profile. A 2.9mm rim offset helps to even out spoke tension for a more well balance wheel.
