Middleburn upgrade and bottom brachet for a Monocog
I have 2011 monocog and need some help.
The bottom Bracket is a FSA ISIS 68mm x 108mm. I am upgrading to middleburn rs8 crankset. I also need a new bottom bracket. Middleburn stuff is cool, but bloody confusing. What bottom bracket do I need for the rs8 and to fit my frame? Also, what tool do I need to remove this stock FSA ISIS 68mm x 108mm bb?
You need a 113 spindle, ISIS or square taper uses the same length (right from their website). I have the square taper version and run a 113 skf stainless roller bb. 68 vs 73 is usually done by spacer.
If you go SKF 113 square taper causes the drive side crankarm to sit super close to the outside of the cup. I mean maybe a 1/10th of a mm close. I don't know how tight the ISIS version would be.
