Your way into gravel
The Topstone CAAD 3 CUES 1x is the most affordable Topstone CAAD with a drop bar. It shares the alloy frame and carbon fork of the pricier models and makes getting into gravel riding easy and affordable.
Model Description
It is built on the SmartForm C1 alloy frame with a Topstone carbon fork, internal cable routing, UDH and plenty of mounts for a rack, fenders, bags and bottles. Shifting is handled by a durable Shimano CUES 1x10 groupset with a 40T chainring and 11-48 cassette, with no front derailleur and easy gears for steep climbs. Hydraulic disc brakes and 45 mm WTB Riddler tires provide confidence and grip on pavement, gravel and forest trails.
