Octalink, 175mm. The interface and pedal threads are all good, and it has the nice self extracting bolts. Good looking first generation Hollowtech with the stiff and durable Octalink BB connection. The outer (44) ring is original, the middle ring is a steel Truvativ and the granny is a steel one pinched from a cheaper Shimano chainset. So - nice looking, lightweight chainset in full working order from around year 2000. £34 posted via recorded post in the UK.
