I get a rough feeling when I pedal, with the gearing all okay, I suspect it must be the bottom bracket. How do I know what type my bike uses? Any site that i can refer to? Are they interchangeable?
If that's a stable high quality MTB take it on your interior sight motorbike shop. setting up a backside bracket demands ineffective-on accuracy or that's going to completely screw up the steadiness of the motorbike. motorbike shops use purpose-made jigs to extra healthful backside brackets.
Generally speaking bottom brackets are interchangeable. However, there are different ways of fitting the cranks to the bottom bracket so be sure that you have the correct type. There are also different thread types, so you've got to be sure you get the correct one. Then there are the different tools that might be needed in order to remove and fit the bottom bracket. I assume that your bottom bracket is not a B.M.X. type? Different B.B. can have different taper sizes. The manufacturers site will probably help you. If your crank arms attatch via a square taper and a bolt that fits through the crank into the bottom bracket axle, you'll probably get away with a Shimano cartridge bottom bracket. Just make sure that the length of the axle is the same as the one you are replacing.
