Trek Boone
CX racers. If you want gravel capability, look at Checkpoint or Checkmate instead.

Sportive and rough-road riders who found R5/S5 too low.
Cervelo endurance road: taller, more tire room, all-day. It is not a slow bike — it is an R5 that sat up.
Gravel riders who want one bike for events and weekends. Racers who want a lower, racier gravel bike should also look at Crux.
Specialized's gravel all-rounder. Future Shock up front (on many kits), generous tire room, and a position between Crux-race and touring. Recent Diverge 4 years shift clearance and front-end feel.
