I didn't do anything for my set up. I just swapped the 20t for an 18t, jumped on and rode.Wanting to move from a 32-20 to 32-18 setup. What will I need to do to the chain to allow the smaller cog? Any other considerations?
Thanks
if you're stepping down, then you may be able to get away by just using your tensioner. If you're maxing on your your tensioner's range, then you'll need to take off a link. Can you give us more info on what bike, tensioner type etc.?[/QUOTE
Trek Marlin SS. I don't have a chain tensioner, it's just built in to the frame with sliding bolts.
Tensioner bolts are currently about halfway back on the 20T and there is some chain slap.
:skep: He'll be just fine with 32x18. Why spend extra on a chainring, lessen clearance, with virtually no benefits?If it were me I would go with bigger ring and keep the 20 tooth cog because the system will run smoother. You could use a 35/20 because it is a very similar ratio to the 32/18. You will need to add some links or slide your wheel forward.
