My LBS talked me into replacing the original square taper (ST) bottom bracket in my 520 after 51000 miles with a Shimano 105 Hollowtech BB by saying that new ST cranks weren't available (it seems that it's only Shimano
ST cranks that aren't available). Now, from the CTC forum
it appears that Hollowtech BBs don't last very long, < 2000 miles some people are saying. This has got me worried, it seems that ST BBs last much much longer than Hollowtech. I've got a Route 66 tour coming up. Should I be looking for an ST BB or possibly replacing the Shimano with a Hope BB or am I looking at replacing a BB somewhere in New Mexico ( I was going to write NM but that's overdoing the initials
Right now I'm leaning towards doing a preemptive replace of the Shimano with a Hope because I like the feel of the Hollowtech setup and the changing is superb. Waddya think?
At the least I can take a spare Shimano BB with me, they are only $20 at REI and don't weigh much.
