size: 420mm


The B135AA SSB handle is a modernized version of NITTO's world-renowned B135 randonneur bar. The basic shape of the B135AA SSB handlebar remains the same, with the same reach (105mm), drop (120mm), and raised shoulders (7mm up), but the clamp diameter has been increased to the modern standard size of 31.8mm and the material has been changed to Heat Treated (heat treated to make it stronger).

The C-shaped handlebars and aero levers are a perfect match, and the smoothly raised shoulders allow the rider to grip the aero levers with a relaxed shoulder and elbow position. The reach is longer (120mm), but it does not feel so far away due to the raised shoulders, and the upper part is very easy to hold due to the longer reach. This is an ideal product for cyclists who like to ride long distances in a relaxed position.

Made in Japan

*The new model has a new pear finish with a shot drop. The 420mm is still available in the previous polished finish, but will be replaced with the new shot silver finish while supplies last.

Please note that the finish cannot be specified at the time of purchasE
