Additional Information

Ensure that your pedals are tightened to at least 310 in-lbs (35 Nm) every 5 minutes for the first few rides. Before fitting, it's also a good idea to make sure your pedal axles are clean (a wire brush works well) then greased before installation.
Similarly, always check crank bolt torque is at least 310 in-lbs (35 Nm) every 5 minutes for the first few rides, then each and every ride after that.
Failure to keep your pedals or crank bolts tight as described above is likely damage your cranks and this will not be covered under warranty.

Please note that the minimum required thread contact between crank arm and sprocket/freewheel is 7mm, and a 1.37" sprocket/freewheel with maximum internal thread diameter 33.80mm (NOT 1.375") must be used. Failure to adhere to this instruction will damage the cranks threads and this is not covered under warranty.

Please note: due to the manufacturing processes used for these cranks, there may be small variations in concentricity between the freewheel and bottom bracket interfaces. This can lead to a certain amount of run out for any freewheel, sprocket or adaptor installed on the crank arm. While this isn't an issue on trials bikes, for applications requiring much higher tolerances we cannot guarantee they will be suitable. Please get in touch if you have any questions.
