are that style of onza crank still square taper?
I had the old, alloy crank arm style cranks (the shortish ones from like 04) and the BB's are awful! i twisted it like anything but didnt realise till i took the cranks off for isis.
crank arms were pretty good though I give them that, pretty light I thought
Onza hubs were pretty awful on mine (I had 04 t-pro) got really gritty and developed a lot of play lol.
