I’m still using square taper in my commuter, the lifespan on cheap shimano sts is better than on expensive externals IME. But the difference isn’t massive and the other benefits of external mean I’m ht’d on all the proper bikes.
(incidentally I remain pretty convinced that the main reason some people get terrible lifespan from shimano BBs but much better from Hope is just that Shimano have no tolerance of gorilla-tightening while Hope do. XT is a very good product these days.)
ok, never heard of the middleburn crank failures but their rings used to be significantly better than the shimano ones.
Maybe so but they never moved on, compared with the modern competition middleburn rings are pretty rotten now- expensive and pretty shortlived, and only adequate shifting.
