"There are now many standards of bottom bracket, despite this the 68mm threaded bottom bracket has outlasted any other design. It is most definitely the most versatile bottom bracket shell. We've spent a lots of time to get the threads just right to work with every manufacture (they all seem to vary slightly). Can be used on road and MTB frames,"
