The Tractor XL sprocket is made from 6061-alloy with a super thick 16mm core diameter that tapers to 6mm thick at the teeth. 

Despite the thicker design, the Tractor XL weighs about the same as traditional sprockets  - 4.0 oz. (25t) and 4.7 oz. (28t) with a 24mm bore (19mm and 22mm spindle adaptors included). 

Power meter with sensors on both pedals. The best choice to take full advantage of the real dual-sided measurement.

Easy to install

Install and transfer your Assioma power meter from one bike to another just like normal pedals, easily and without extra tools. Just screw them on your bike crank arms and you are ready to pedal!
