    Right sided threads on left side crank arm?

    Just got a new crankset. Weirdly, the left crankarm have right sided threads, which is something I havent seen before. As anyone seen this before? Is this a defect?

    To be clear, I'll need 2 right side pedals to use thé crankset... Odd!

    It could be a crank arm off a tandem. The front crankset of a tandem has the single arm on the right hand side. They appear on ebay from time to time as single speed cranksets. The arm with the chain ring needs a heli coil and the normal (rear) single crank arm is used.. Maybe you have the single arm from the front of a tandem ie with a RH thread. ( if I havent confused myself with the thread directions but hopefully you get the idea)
    Duct tape iz like teh Force. It has a Lite side and a Dark side and it holdz the Universe together.

    oh, thanks for this info. I got the cranks from CRC and where not advertise as tandem cranks or anything similar like this, just another regular sram crankset... I'll check with them!
