Thanks guys for the helpful info!

One last question, could anyone ID my set? I've temporarily installed these onto my Trek and I cannot shift into the smallest gear. I don't know if I've installed them incorrectly, or if my cranks are too wide (is that possible?), or if the set is just incapable of handling a triple. Just fyi, the front gears are 52-45-28, rather big lol.



Thanks again!
