Jamis Ventura A1
Details
BUILT FOR SPEED. HIGH IN COMFORT
Our Ventura bikes borrow heavily from our race-proven geometry to help keep you in front on the local Saturday ride. But we've softened the edges of that geo just a bit for a more comfortable and confident ride so you can head out again on Sunday, still fresh and ready to hammer your buddies one more time.
RIDE TUNED
Having chainstay-mounted disc brakes frees the seatstays from their traditional role of brakes reinforcement. So we can focus on designing and tuning the seatstays for their primary purpose: ride compliance and torsional stability.
