i managed to get a 55t on ebay and chucked it on some old busted tunes i had - turns out the Q factor on the tunes is wider than the stronglight cranks so my heels have even less chance of catching + they feel a crap load stiffer which isn't something i thought i would notice at all... i've also just got a 56t ta ring on ebay so am going to switch to 175 crank arms with i can find some cyclotourists
