spawtydawg Posted September 12, 2019 Report Share Posted September 12, 2019 (edited) 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.

furse Posted September 13, 2019 Report Share Posted September 13, 2019 Im running 13/53 on mine, would like to try it slightly higher. Can I ask why are you using 520 chain? Quote Link to comment Share on other sites More sharing options...
spawtydawg Posted September 13, 2019 Author Report Share Posted September 13, 2019 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?

b40rt Posted September 13, 2019 Report Share Posted September 13, 2019 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. Quote Link to comment Share on other sites More sharing options...
spawtydawg Posted September 13, 2019 Author Report Share Posted September 13, 2019 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? Quote Link to comment Share on other sites More sharing options...
furse Posted September 13, 2019 Report Share Posted September 13, 2019 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. Quote Link to comment Share on other sites More sharing options...
