He also pushed Ritte to agree to allow him to use more than one fork offset. Many brands use the same fork for all frame sizes for simplicity and as a cost-saving measure. But Kellogg—obsessed with geometry and bike handling—wouldn’t abide such shortcuts. Ritte acquiesced: Smaller sizes use a fork with more offset, larger sizes use a shorter offset fork, providing Kellogg more freedom to refine the geometry.

In one such instance, Kellogg “under-trailed” the gravel bike (a medium Satyr has less trail than a medium Phantom). “When gravel gets big, the front end tends to get thrown right and left,” Kellogg says. “When you under-trail a bike, it tends to autocorrect. It’s self-centering.” He says this makes the bike less tiring to ride because it requires less attention.
