2021 Ventura A2
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.

A WINNING BIKE FOR EVERYONE
Our Ventura Series bikes have won Bicycling’s coveted Editor’s Choice award numerous times. Which is why we offer the Ventura A1 and A2 in both male and female specific packages.
SIZE SPECIFIC FRAME DESIGN
Size Specific Design (SSD) is the Jamis design philosophy and technique used to create the best possible riding bike for each size rider. Rather than limiting frame size variations to just different length top, seat and head tubes lengths, we take an all-inclusive look at each frame’s total configuration. Every SSD frame will also feature size-specific BB drop, rear center, fork offset/trail and SST technology.
THE DISC REVOLUTION IS HERE
We are all-in. Disc brake technology provides superior stopping and safer braking no matter the conditions. They offer increased control and better modulation as you vary from being at-speed to slowing down or stopping. They are significantly less affected by rain and wet conditions, and eliminate any rim heat build-up that can come with caliper brakes. Gone is the need to be concerned with carbon rim deformation. Whether the streets of NYC or LA, or long and winding open roads, the control and safety that comes with disc brakes will only heighten the experience that comes with a riding a Jamis.
GENDER SPECIFIC GEOMETRY
Our Ventura Femme versions offer women’s specific frame sizing & geometry and component selection, including anatomically adjusted top tube lengths, head & seat tube angles, fork rakes & women’s specific saddles, with handlebar, stem and crank lengths all dimensioned to optimally fit women for greater comfort & efficiency
VERSATILE PERFORMANCE GEOMETRY
For a greater range of handlebar and rider positions, we’ve fitted the Ventura series frames with taller head tubes. Coupled with a slightly longer wheelbase and relaxed head tube angle, this results in confident, steering/handling and a more comfortable position for longer rides whether competitive or recreational.
ECO CARBON FORK
ECO stands for Enhanced Compliance Offset. The ECO fork blades are swept forward a few millimeters to provide vertical compliance for a more comfortable and controlled ride without any compromise to lateral stiffness, thanks to the reinforcing rib on the inside of the fork legs.
FULL CARBON MONOCOQUE FORKS
The carbon forks on our Ventura A1 and A2 models are formed as true monocoque forks, in one continuous unit (steerer/crown/blades) for optimal strength and performance. Our competitors often use heavier 3-piece bonded carbon/alloy forks in this price range.
TAPERED HEAD TUBE AND STEERER
By enlarging the bottom bearing of the head tube from 1 1/8” to 1.5”, not only are head tube stiffness and steering precision increased, but we have sufficient room in the crown to produce a truly hollow fork from the dropout, up through the crown and steer tube, which yields exceptional compaction quality for increased strength and reduced weight.
