THM Ulna is a total re-think of a handlebar: the main driver for your comfort and control on the bike.

For the Ulna we went all-out, modifying our proprietary THM-RTM process to allow for an internal structure that greatly boosts its structural properties while decreasing its weight. The internal structural rib running through the drops is a real technical marvel, it’s almost a shame you’ll never get to see it unless you own an X-ray machine!

Combining this structural design with THM’s intricate layup and carbon grade selection renders the lightest handlebar for real riders, with an incredible 110 kg weight limit.
