    DH/AM cranks on a rigid all-around 29er?

    So, I am trying to pick out a single speed cranks set for my all-arounder Ogre build.

    The Shimano Saint M810-1 has really caught my eye, mainly because it seems tough...overbuilt even.

    I guess my question is this: How stupid is it to use a "down hill' or "all mountain" cranks on a bike that is mainly a trekking style bike?

    I am a clyde so I am looking for a super sturdy crank set, any other cranks I am overlooking?

    As long as parts are compatible, I don't see why not. I'm a baby clyde (5'6" 220 lb) on rigid ss 29er with lots of air time, and I've been slowly upgrading my Kona Unit with Raceface Turbine parts. Tough enough for downhill, light enough for xc.

    I used raceface DH cranks on my rigid for 2 years because I got them cheap. Aside from being heavier they all work the same. You put your feet on the pedals, make them go round and round and the bike goes zoom.

    What BB/BB interface style are you planning to use? Square taper? ISIS? Hollowtech? That's a huge factor in what is available for you.

    Actually I am open to suggestions as to the strongest, trouble-free set up possible.

    Weight and Q-factor are non-issues...

    RF 2-piece has known wobble issues so I implemented my own fix and rode this setup for 2yrs trouble-free

    I have Saint cranks on my burly rigid SS 26" trail bike. the cranks are certainly strong (and they fit the color of the bike )

    The BB is something to look after. Make sure the installation is tight and stays put. And replace if/when in doubt about its condition. Right now my theory is that, in external BB's, the DH versions with longer threaded sections make sense for a heavier guy riding SS.

    "it IS possible that you are faster or slower than anybody else who is having at least as much if not more or less fun"

    Sweet. I am set to try a similar JB Weld bodge to still the wobbly spider on my aging FC-752 cranks. I hope it works...
