    Eccentric question

    I'm sorry for having so many questions but this is the first tandem project I've ever attempted.
    My new 26 inch Tsunami tandem frame did not come with an eccentric.
    What kind do I need? I saw several different one on Tandem East's website.
    Anyone know?
    Again, thanks for your patience with my endless questions.
    Steve

    Think I've figured this out. It appears to be a standard 54x68mm.
    Would this one work?

    A phone or an Email account...

    Contact Chucks and tell them to send you one, it should have come with the frame and, moreover, since it's their own house-branded tandem they are technically the OEM / source for the correct eccentric.

    Make sure the set screws are also there. Mine came from Chuck's without these...Chuck told me "you can just go to any hardware store and buy them." While this may be partly true it was still a pain to have to go find these at the hardware store when I had no idea what they looked like. Chuck is a little cheap at times.
