mech and gear ratios?

Posted on
  • will a 11-36 with a 40t work with a 10sp long cage derailleur? what chainring tooth count would be best with this set up?

  • Depends on the make and model of your mech. It will have a total tooth capacity which is front rings range plus rear cassette range. In your case, it’s 0 + 25 = 25 teeth.

    The chain ring size depends on the gear ratios you want. In your case it’s 30-98 inches which is ok for most riding.

  • Helpful thanks, sticking on a 39t though.

  • No problem. 39T gives you a range of 29-95 inches.
