Pronounced “tri-ax”, the new 3ax clipless pedals introduce sideways tilt to your foot, allowing it to move in a more natural motion as you push down. They claim this makes you more comfortable, more powerful and less likely to endure repetitive use injury.
The secret is the ability for the pedals to roll along their longitudinal (nose to tail) axis, with springs inside to add tension so they don’t merely float and feel unstable. It’s only 2º in either direction, but they say it’s enough to maintain better overall foot/ankle/shin alignment. The result? Your knees end up with an average 17% less sideways movement, which means less strain on the joint, and overall efficiency gains of up to 5.47%.
UPDATE: Current prototype weight is 188g per pedal (376g / pair), but they are working to bring that down before production.
