Thomson premium carbon fiber drop bars are the perfect pairing for your X4 stem. Light, strong, and engineered to be the best.

Made with Toray lay up and Nano Epoxy Resin for high impact resistance. 

The round cross profile features a custom ergonomic bend. Concave shaping on the bottom tucks and routes the housing to be out of the way. The top profile is round and wide allowing auxiliary brake levers to be safely used with lots of room for your hands.

• Round cross profile available in 40cm (137mm drop), 42cm (140mm drop), 44cm (140mm drop) and 46cm (143mm drop). Reach 78.5mm

Molded with an EPS inner mandrel (over cheaper bladder style) to avoid wrinkles during the vacuum bagging process. The result is a perfect one piece molded bar, with zero inner wall imperfections. The process yields precisely engineered stiffness and flex, while keeping the weight to a minimum.

1.5K woven impact ends help prevent damage to unidirectional fibers from impact.
