    Hi there
    I need a new crank arm for my 105 group set and thought that it would be easy to order but apparently not. There are a few on ebay but I was wondering if anyone knew of another way to get hold of one?
    Thanks in advance
    Andrew

    I think I’ve got a spare one.
    I think I’ve got a spare one. I’ll need to have a look tonight.

    It will be 5700. It came off my first 2012 Roubaix. I’d only done about 400 miles when I got hit by a car. The frame and wheels were knackered but left crank was one of the bits that was fine. When I had a new insurance rebuild I went with Ultegra so didn’t need it.

    I’ve also got a full 105 5700 Compact 172.5 chainset in Black as when I built a new winter bike last year I had knee trouble, got a bike fit and ended up changing every bike to 170. The winter bike had only done 200 miles so the 172.5 that came off is practically as new.

    Found it. You can have it for £10 + cost of postage, £2-£3 I’d guess

    does it have to be a 105?
    does it have to be a 105? I’ve got a tiagra one, never used.

    I think you can buy from some of the cycle stores as a spare part too.

    UPDATE
    http://www.petracycles.co.uk is where I bought the 165mm crank arm I needed.
    they have 105 parts too, I think Y1M398060 is the 170mm part number.
