September 12, 20196 yr Hi everyone, as above... What gearing is the prefered choice when using a 520 chain set up? Clubman/intermediate rider, doing classic trials, Kia rounds etc. My bike has 11/51 gearing. Have recently purchased the bike and haven't had chance to ride it in anger yet, but wondering if 11/51 will be too tall. Thanks in advance.

September 13, 20196 yr Im running 13/53 on mine, would like to try it slightly higher. Can I ask why are you using 520 chain?
September 13, 20196 yr Author It's what the bike came with when I bought it. Are you using a 428 chain? And am I right in thinking that the equivalent gear ratios, ie 12/48 for example would be taller if using a 520 chain setup, given that the spaces between each tooth would be larger?
September 13, 20196 yr 13/53 = 4.07:1. 12/48 = 4.0:1. Virtually the same. Nothing wrong with good quality 428 chain, more than capable of handling the power / weight.
September 13, 20196 yr Author Yup, I agree that a good quality 428 chain would be ok, but as the bike came with a 520 set up, and is almost new I'm reluctant to change it. Furse, 13/53 that's quite tall gearing, I take it the bike must handle it ok seeing as you want to go even taller?
September 13, 20196 yr I use 1st in most sections, but if there is a good climb at the end 1st can be too slow, 2nd to fast on the flat. They are fantastic bikes, that little bit better than the minarreli engine.
