    Converting a 3x9 to a 2x9 or 2x10????

    I'm looking to convert my Tried and True Asylum from a 3x9 to a 2x9 or 2x10 and just looking for some confirmation of what I can (and can't) do or will need to make the change.

    2x9 is pretty simple - just need a new 2x crankset. Can I use a 2x10 crankset with a 9 speed chain? I'm using XO grip shifters so no need to change anything out there.

    Is it possible to change to a 2x10?
    Rear hub is a WTB hub, 9 speed....I assume it's 10 speed compatible???
    So if I can go 10 speed I assume this is what I'd need: 2x10 crankset, 10 speed rear shifter (do they make a 10 speed grip shifter?), 10 speed cassette and chain. Is my current XO rear derailleurs ratio 10 speed compatible?

    Thanks

    The 10 speed cassette will fit where the 9 speed one does. The derailleur needs to be changed.
    I believe there are ten speed gripshifters now.
    I've done a 1x10 recently and a 2 x 10. On both, I used Salsa rings. They say they're for 9 speed chains but I've had no problems. I also have the same Shimano 32 tooth chainring on my 9 speed bike as my buddy has on his ten, so it doesn't seem to be such a big deal.

    To go 2x9 just remove the big chainring and replace with a bashguard. Reset the high limit screw on the front derailleur and you're done - no need for a new crankset. You can do the same thing if you go 2 x 10.

    To convert to 10 speed you will need a new cassette, shifter, chain, and rear derailleur. Not really worth it for one extra cog IMO.

    2x10 gripshift is available, but quite expensive for 1 extra cog - $200+ for shifters as I understand. I would stick with 2x9 until prices come down on the 10speed shifters. I'm using 3x9 gripshift too, and I am thinking about going 2x9. I won't give up the gripshifters, though.

    The 10 speed grip shifters make even the X0 9 speed grip shifters feel like toys.

    I am running 9 speed (Dyna-Sys) rings on a 10 speed SLX crankset on a 10 speed system. I went with 22/36, with the 36t chainring made for the 9 speed SLX 22/36 crankset. It is made to work with a 22t small chainring in that the ramped section is of a smaller diameter (makes the chainring look kind of . . . . thick/deep) so the chain drops straight down further before being ramped over toward the small chainring. It may be much ado about nothing, but I can say it works great for the bike I am riding (2011 Anthem X 29er).

    The part number for the 36t chainring I am using is: Y-1KG-98050

    Good advice right here. Slap a bash guard on it and save your money for other riding gear.

    Is this 2x9 setup 29er specific? Are there no mods in this forum?

    I'm using a 10 speed chain on my 2X9 set up. No problem.
