Hey guys. IT'S MY BIRTHDAY!! 24!
Anyway, I'm replacing my mtb's bottom bracket which is a 68 / 121-ish length. I am having a little trouble finding bb's of this length. Is this an odd size?
Also, I have purchased a tool kit for regular maintenance of my mtb. I am interested in finding the best resources for maintenance and repairs (books, websites, tutorials).
I appreciate any input.
