I have a bike with the Ultrgra 10-speed from 2005 or 2006. It has about 700 miles on it. It features the cranks described in this document - Hollowtech II.
I'd noticed that the crank bearings seemed a little stiff. Took the chain off and spun the cranks. If I push them hard, they will spin maybe twice and then stop. Contrast this with a bearing on another bike that's 20 years old and just spins indefinitely.
Now, because of the design, it does not seem that one can lubricate the botton bracket at all. I hesitate to even try to get in there, because you need a g-- d--- torque wrench to put the crank arm back on!
Is this something that will just wear in? Can I adjust or lube this myself without a torque wrench?
Should I just ignore it and develop massive thighs from all the extra work I am doing on my rides?
Thanks in advance for your help.
