Hi guys
Can't find anyone that can help me with different gearing setups, ie sprocket tooth sizes, front/rear ratios etc
Would like some different setups for this season but don't know where to start and have
15/40 standard ATM??
Also will a 520 chain fit straight on with the appropriate 520 sprockets?

You may be better of asking in here viewforum.php?f=58
General opinion is 14/41

Will do thanks
