those are 9-speed cranks. the rest is M737 8speed by the looks of it, and tasty kit it is too.

Cranks are M752, brake levers are M739 or M740 and I bet the derailleurs are that same gruppo.

Might be wrong (and usually am) but don't think the front mech is M737. As for the rear mech, I'd have a bloody hard time telling M737 from M739 without looking at the code stamped on the back! :lol:

Well where does that leave me on the other post i made over chain would i need a 8 speed or 9 speed chain given that its a 9 speed crank if i am restricted to 9 speed then so be it but i really wont use the extra gears right away as its generally a lets get fit bike, and eventually venture into something more, i will be fitting a 737 8 speed cassette to wheels if thats fine and will work with the crank

But it will work better with 9-speed chain with regard to noise and chain rub.

My impression is that you need to use an 8-speed chain with an 8-speed cassette and mechs. That's why chain manufacturers still offer 8-speed chains as well as 9-speed.

And I thought that although a 9-speed crankset isn't perfect with an 8-speed chain, it will work fine. If it didn't work fine, surely you would find chainring manufacturers offering a choice between 8-speed and 9-speed rings, but they don't.
