I know this isn't scientific but I think it will be interesting...
Hey, can you help me collect some data on bb resistance - AKA spin their BBs with their index finger? - NEW Quote | Reply
Can you kindly remove (or hold back) the chain and give your crankset a good spin with your index finger?
Please report back how many spins your crankset spins and what type of bottom bracket you have.
My 1999 Ultegra 9speed with octalink (internal) bb gets 6 revolutions.
My 2007 XTR (external) bb gets 2 revolutions.
