More control on rough gravel
The Topstone CAAD Lefty is the Topstone CAAD with a suspension fork. The Lefty Oliver with 40 mm of travel soaks up roots, potholes and coarse gravel, giving you more control and comfort when the going gets rough.
Model Description
The SmartForm C1 alloy frame with internal cable routing, UDH and plenty of mounts is designed for a suspension fork from the start. The Lefty Oliver uses a Gen 2 Chamber Damper and can be locked out for smooth sections. Shifting comes from Shimano GRX 1x12 with a GRX 822 rear derailleur and 10-51 cassette, stopping from hydraulic GRX disc brakes. WTB ST i25 rims and 45 mm WTB Vulpine tires provide grip on loose ground.
