With the X-12SL-A1, Aerozine offers a lightweight singlespeed crankarm. The low weight is achieved by the 24mm integral axle made of AL7050T6 aluminum, while still offering sufficient axle stiffness. The crank is on a par with a Shimano XTR crank in terms of weight and workmanship.
New clamping of the left crank arm with conical toothing, easy assembly and disassembly thanks to integrated crank puller!
ALS (Adjust Length System): By using eccentrics on the pedal mount, the crank length can be easily changed. For example, by turning the 170mm eccentric, a 175mm crank is created. Optionally, an effective crank length of 172.5mm is also possible using other inserts.
