Have SRAM updated the Hammerschmidt since launch in (IIRC) 2008?

    dont believe so.

  • No - that's what I thought. Pity; it was an idea that sounded good (especially given the amount of chainsuck I get) but seems to have needed more development.

    i was looking at getting one of these but am a bit worried of the facing procedure, anybody know of a decent place in essex that would be able to carry out the facing procedure. I really wish to pay out for the tools to do it myself.

    Whilst there's a good chance it would eliminate chainsuck due to you running a new chain and chainring, it is quite possibly the most ludicrously expensive "cure" for it.
    You're much better off just finding out what's causing it, and fixing it.

    Open to suggestions on that one. Vile riding conditions I can do little about; chain and rings not excessively worn, nor brand new (which I gather is also a cause).

    Considering giving 2x9 a go as theoretically less front shifting would mean less opportunity for chainsuck, but equally some people say running a double at the front leads to more front shifting.

    Maybe, but a lighter, less draggy, more trail orientated v2 epicyclic front would maybe have been the end of front mechs. Don't have much trouble with shifting at the back; also not sure XX1 makes any sense from a weight distribution POV.

    Whoa there! Hammerschmidt was never lighter!

    Also, what you're experiencing is not chainsuck.

    Hammerschmidt - lighter? The full combo weighs 1.54Kg

  • I didn't actually say a Hammerschmidt was lighter. However, with development there's no reason to believe a trail orientated v2 wouldn't have been lighter.

    As I understand it, chainsuck can occur when in one ring, or occurs when you shift. I get the second kind (chain jammed up between the rings & the chainstay).

    you will need to ask about as not many places will have the required cutting tool. but it is also not always required.

    Chainsuck can occur when the chain and ring are worn, even on a single ring.

    again it depends to what you compare it to.

    compared with like for like at launch it was about the same.

    Indeed Nick, but about the same is not lighter....

    On my bike (yeah I'm budget conscious) I run 22/36 double (steel rings and Truvativ bolts off a powerspline chainset) on Deore HT2 cranks and BB with a Deore mech, old style X7 shifter and cheap cables, total weight for comparison is 1,243g. For referance that whole lost cost me less than £35 (pre-loved).

    Yes, again I don't dispute that, but the problem I get is when shifting.

    Sounds like setup problems, not chainsuck.

    No, definitely chainsuck

    So, you're saying that chainsuck doesn't occur on shifting front rings? :roll:
  • cooldadcooldad Posts: 32,599
    Millions of people shift gears every day without chainsuck and /or a Hammerschmidt.
    But it's one way I guess.

    Thank you so much for taking the time to give me that useful input.

    He does actually make a very valid point.
  • The RookieThe Rookie Posts: 27,804
    As it's a rarity it's worth repeating, Cooldad makes a very valid point, millions of shifts are made every year without chainsuck, suggesting somewhat that if you have chainsuck on shifting it's not exactly unfixable and for a lot less money than adding an extra 300g plus to your bike at significant expence.
