Hello. Ive done a search and cannot find any information about rear chain guide modification. I want to Run a 52T rear sproket with my 13T front for the tight woods here in BC Canada. I suspect when i install the new 52T rear sproket with the 13T CS i think the chain will rub badly in the rear chain guide. ANy suggestions?
Also, do you know the length of the chain i should use because the stock chain is going to be too short.
Using my chain spreadsheet, looks like a 13/52/110 will be 0.24" shorter than the stock setup (13/47/108), and a 13/52/112 will be 0.40" longer. You need to decide if you want to shorten up or lengthen the w/b a bit.
I am with canyoncarvr use a 12 tooth and it is simple--no changes in chain length or guide required--even change back to 13 tooth in a jiff if you go riding in a flat or high speed area!!
On the chain guide topic, mine is worn out and it will need replacing before I start riding this year. I priced the stock pieces->$80 CDN. The Moose guide (which I believe is the same as the FRP guide...correct me if I am wrong) retails for $35 US..roughly comparable in price. Now my question is this: The stock chain guide has upper and lower wear blocks...but the Moose version appears to have only the lower wear block. Is this an issue?
