Thanks – square taper noted, and is a good shout, but would like to stay with HTII if I can as I have the tools and all the bikes now have it. Also, I tend to have no issues with HTII BB life, but lets not open that can of worms on a Friday… 😉
Have looked at true track chainsets, but agree chainring BCD is limiting for the ring size I may need and crank arm lengths tend to be on the small side.
My preffered choice is either the Alfine cranks, though I don't really like the look of them with the chain guard (but they are cheap) or some R600 compact cranks with a single ring on it (that looked nice on that single speed MTB thread from a few days ago), but that is pricey unless some turn up on the classified or EBay
