Cast in aluminium to the highest standards.
Trialcast Cams allow a greater range of wheel adjustment so you don't have to buy a new chain so quickly.

A unique feature of Trialcast Cams are the fact that they are right and left handed. The sweeping arrow shows the direction of movement and the cleverly designed lettering around the lugs allows for very easy adjustment. Just match the letters on either side and the cams are identically matched. No need for counting the lugs or guessing the right position.
They are 6mm thick with a 17 mm bore.
