• Guys, this is quite a broad question, but has anyone had trouble with a chainring being too big for a pre-cursa? I want to give mine a 58 or a 70 tooth for an attempt at some mad speeds for fun, but don't know if they will fit okay. I'm sure the 58 would be line since its had a 53 on there and there was clearance, I just can't remember how much :/

    Cheers

  • I had a 61T on mine. Was fine

  • May depend on how old the frame is...
    I sometimes get chainstay rub from a 53t Zen (spindle & frame flex), but my frame's an older model with straight chainstays. The 2017 ones appear to have a bit more space.
