I am about to replace the front ring and chain-ring on a Bosch emtb , but not the cassette, mostly cos its a bit pricey and it doesn't look worn. The original is a 17T and I am replacing with a 15T thinking that as most of my miles are done at 16mph ish using one of two gears the smaller ring will use a different two at the same speed so will lengthen the life of the cassette.. Hopefully!
Anyways, right or wrong that is what I am doing...
Normally for a chain change I just lay them side by side and cut the new to suit the old, but by going down two teeth do I need to make the chain any shorter or will the 2T difference not be noticeable?
I tend to think it will be ok.. just not sure.
