TJ – you’re obviously a big fan of Octalink, but I had a couple of them and they had the old problems of square taper (thread loosening from NDS cranks if you’re goofy-footed, leading to rounded tapers) without really solving the issues. As all the people who use UN73s can point out, if you get on with them, the sealing and bearings are pretty much bulletproof in square taper BBs.
Plus Octalink are getting scarcer to find, no?
In the end, after spending a packet on decent cranks, BBs and getting them fitted properly, I just gave up and went to HTII. I’ve not ridden it much yet, but so far no rounded tapers*
*I know, the axle’s round already, so there.
