Back to square taper! Anyone else given up?
Another one here. I had Octalink for a while - it came standard on my old Kona - and the splines wore away. I ride goofy-footed, so the non-drive crank loosened off.
But the two bikes I've built since (4 years now) have both had square taper, with some secondhand Turbines that I picked up on here. I had one non-drive crank round off its tapers, so now use judicious amounts of threadlock and retighten occasionally. No worries.
In fact, it works so well I'm struggling to justify some RS7s (even at £100) to myself. Booo!
ahhh :-)just as I needed a new BB and was wondering whether to convert from ST, the answer (as ever) arrives here.

I always thought square taper was the most god-awful creation. BBs never lasted me more than a year (and I was only riding once a week then) bent axles, worn tapers, hard to remove (Always waiting for the threads to strip as I pulled the cranks off) unless they fell off mysteriously mid-ride. Hopeless rubbish IMO,
Personally I'm glad to see the back of it.
HTII on three bikes (commuter coming up to it's 10,000 mile birthday) and never had a problem with any of them. Apart from the Cheese-Rings (TM) issue, the only other problem is the tiny pinch bolts. Had all three frames faced before fitting and they've all been fine. As well as the stiffness, I like being able to take the whole thing apart with an allen key.... always seemed to end up with creaking from sqaure taper from making/breaking the interference fit between the cranks and the arms.
EDIT: ^^^ What Peter said...
I agree PP, I always thought ST was a god awful creation, and that HTII was the answer to all my bottom bracket related problems. But it's not been good to me. I have no idea how you got that many miles out of yours bristolbiker. For the record my frame is faced and the bbs have been installed correctly! I think I just ride in crappy conditions too much.
The commuter see's almost exclusively road miles (Airbourne Carpe Diem frame with mechanical discs, so it gets a very occassional through-the-woods bash when time/conditions permit). As I say, the fact that it's only a case of undoing the two pinch bolts and you can have access to the BB cups means that I actually do more maintenance with HTII than square taper. I generally take the cups out and clean/regrease every 6 months or so and that seems to have kept it sweet.... to the point that the rear hub bearings are about to die first - go figure!
So what are the crank options if you want to stick to square taper?
Crank options for ST depends on geared or SS but:
- Old, quality XT/XTR/Raceface 2nd hand cranks
- White Industries
