Crank arm length?

[musa]

I want to purchase a new ultegra chainset but how do I find out the length I need i.e. 172.5mm on the existing one I have

do you have any issues with the one you have (pain, numbness, discomfort, etc). If not, then buy the same length.. Changes are you are not going to notice the 2.5 mm increase/decrease

Merlin have it for £124.99 including BB

That is CHEAP. I've just bought an Ultegra grey double from Wiggle, and I thought that was a good buy at £149.99!

I doubt you get the BB with it though. I've never know that to be the case and IMO it's just a bit of ambiguous wording, but if you do then it's a really great buy.

Yeah I'm not holding out on that, I bought the BB already so not at a loss
