Subject: Big ring / medium or Middle ring/small? Posted by: Scot on December 09, 2001 at 09:58:30:

Message: I have been doing a lot of riding lately on a relativly flat packed dirt path, so I am cruising along between 12-14 mph, which for me is a good pace. I have noticed that its about the same gear ratio if I run the middle ring and the two smallest cogs in back OR if I use the big ring and the middle cog and maybe one slightly bigger. I know not to run extreme gear combinations (big / big or small/small) but the chainline appears about equivalent for both and I'm not getting any differnt front detrailer noise with either setting (by the way, how to you trim out that last bit of front derailer noise with Shimano shifters?) Any thoughts? SGM
