    2x9 Mountain Bike Setups

    Has anyone ever setup a 2x9 on a mountain bike?

    I can't find much info about it, and can't find any cranks at the moment that come as a double. Just curious if anyone has any experience...

    Bash Ring replaces outer ring, then just up the middle and granny gear sizes.

    +1. It is what I did until I went 1x9.

    The Truvativ Stylo 2.2 is a double all mountain crank with a polycarb bashring is you want to go that route.
    Falling is learning...[SIGPIC][/SIGPIC]...learn to not fall in a box.
    Any good American will watch THIS -and- WHERE WAS MY BIKE MADE?

    +2...I use a bash ring on my FSA crank. All you have to do then is adjust the front derailleur so that it won't attempt to push the chain up on the chainring that is no longer there.
    It's better to burn out than fade away...or slip out of your pedal and face plant on the side of the road!!!

    Woops... I should have mentioned that I'm talking about XC race setups. I wasn't thinking about the more common DH cranks.

    What size chainrings would you want to use?

    Stronglight Oxale is available as a double for XC. Also favoured by some touring types apparently.

    Put in the bash ring and then just be careful not to try to shift onto the ring?

    Nope...adjust your front derailleur outter limit so that it WONT shift into where the outter ring used to be. My Rush 800 is set up this way as well. FSA Mega EXO cranks with the outter ring removed and a bash guard in it's place...I simply never go fast enough 95% of the time to need the big ring as I just free ride not race.

    I use a 2 x 8 setup on my XC race bike. Crank is a Middleburn Duo with 29 and 42 rings. I use a LX 580 front mech with the high limit screw all the way in an have it setup for 1st gear on the 29 and 2nd on the 42. Works like a dream and is a great race setup if you don't have massive steep technical climbs where you race, which I don't.

    The most popular method to go double for XC race is get an old 5 bolt compact crank (Raceface NEXT LP is the gold standard) and get 29 and 42 rings (or 44 is you have massive top end!) bolted onto it.

    I'd probably go with the 29/42 like some others are mentioning.

    Thanks everyone for the crank recommendations!!

    I'll keep the Middleburns in mind, they look pretty sweet.

    I had nice Raceface cranks on my old Giant, too bad it got stolen.
