Ok is there a advantage of changing to a single gear on your crank? I don't use all the front gears.
If there is what do I look for? Thank for your help :D

    A bit more information would go a long way, why are you not using all your chainrings etc.
    Now where's that "Get Out of Crash Free Card"

    Yeah sorry! I'm a mechanic and I always ask that...
    I do road and dirt trails, nothing as in MTB trails.
    My bike is a Caloi Pro-Xc 26"?

    Well i use ll the rear gears and keep the front on the highest gear 95% of the time.
    For how I ride it works for me.

    With the single gear in front you gain simplicity and a few grams less. Thats all about.

    Thanks for the response! I do like simple lol ok one more question
    I took apart the crank and the bearing assy or bottom brace is a BBLP27 then it has 68 then BC1.37X24
    The original bearing is no where to be found, I've googled it and comes up a BBUN55 but there are a few different sizes
    and I can't find a solid measurement, the one that seems to pop up is 68x110. Can some one can point me in the right direction lol

    BB size depends on the cranks used, so if you are planning on changing your cranks, you need a BB compatible with the new cranks.

    A solid measurement comes from laying a rule across it!

    Most will write it on the BB she'll but maybe it's come off, all the dimensions you quote are for a standard English thread BB shell and the centre housings are the same regardless of axle length.
