A mate gave me a set of rotor cranks. I'm not so sure about
Elliptical chainrings but thought I'd use the cranks and just put round
Chainrings on them. Can a use any regular chainrings? I need to check if they are
110 or 130 . How can I tell the difference ?
Thanks

    geometry

    110 bcd, adjacent bolt holes will be c. 65mm centre-centre

    130bcd, c. 76mm centre-centre
    my bike - faster than god's and twice as shiny

    Praxis works chainrings get my vote.
    Red bikes are the fastest.

    Cheers it's 130 based on that
    Praxis nice but quite pricey ?
    Maybe stronglight ?

    Stronglight are good, praxis are better: you get what you pay for.
    Red bikes are the fastest.
