    Going 1x10 on Stumpjumper Comp FSR 29

    Looking to convert my SJ FSR to 1x10. What would I need other than a chainring and removing the front derailleur? I would use a narrow wide chainring.

    A clutch derailleur. I'd suggest a Shimano XT Shadow Plus, or Zee Shadow Plus.

    Yea it should be, if you want you could also get one of those giant cogs wolf tooth makes if you don't have a low enough gear for the climbs. Replaces 17 tooth cog and you add on a 42 tooth on the end.

    I have the Evo version of the same bike. I dropped the front derailleur, roller guide, and granny gear. Put a Wolftooth 32 tooth chainring on along with a BBG bash guard, and am loving life. I ride very rocky terrain, here in Las Vegas, and have not had one chain drop issue.

    Also, if you want a larger front chainring, the X9 derailleur is already close to its max.
    Enjoy!

    I'm good with 32/36. That's what I run on my evo HT. I have no use for the small chainring. Thanks for the info. Did you keep the same cranks and all? I was deciding between 32t wolf or SRAM x01

    I kept the cranks. More of a money thing, as I wanted to do other upgrades. It was a simple conversion and haven't regretted anything.

    If you dont mind.
    Looks like the wolfs are sold out. Will this work?

    I don't have much experience with the Sram setup. It seems like it would do the job. Maybe someone else that has used it can chime in.

    There is a thread here on Mtbr, can't remember where, that listed off several other companies that make narrow-wide chainrings. Raceface, but I can't remember any more.

    I just converted to 1x10 with a mid cage x9 and love it. Im using a wolf tooth front ring and have had 0 issues. I have a new 104 BCD 30 tooth ring (wolfs tooth) if interested.

    I have a stock 12 fsr comp 29. I want to do this but need someone to guide me. Want to do it the cheapest way hoping to drop some weight by removinging chain ring, Derailur, and shifter.

    Got my Chainring in yesterday, waiting on my new chain. Old one has some bent links anyway. Should be installing in the next couple of days. I'll post pics when I'm done.

    You can just buy a chainguide if you want, that would be the cheapest way. I had an Epic with an XX drivetrain and used a standard ring and an E13 chainguide and never dropped a chain. XX derailleur was not a type 2 and the chainring was not a narrow wide. You can definitely do it cheaper than buying a new derailleur AND chainring. Of course, this will depend on your terrain. I live in upstate NY so the trails aren't brutal, but definitely have bounced it around quite a bit with no issue whatsoever.

    I rode my Enduro Evo at Whistler with a Raceface 34t wide-narrow front ring and an x9 type 2 RD and no guide and never dropped a chain.

    With a 29er I'd probably go with a 30t front ring or you will have a tough time on any steep or extended climbs.

    So get this: E13 XCX BB Chainguide | E13 | Brand | www.PricePoint.com

    Then remove my inner chain ring? I would like to drop the bash guard too. I am guess i am going to need some new chainring spacers.

    That's basically what I had but since I had an Epic it was direct mount. So i'm not exactly sure what model chainguide you'd use but if that one will fit, then yes, that is all you really need. I didn't have a type 2 derailleur or a narrow wide chainring and had zero issues. I'm sure a type 2 derailleur is optimal, but I didn't go that route.

    Finally did the conversion with the wolf tooth ring. It's quiet and definitely shaved some weight off. Liking it a lot so far. I think I need another link removed from my chain though.

    The size of the front chainring does not affect the rear derailleur. Just use a longer chain

    I just picked up a Race Face Narrow wide 32T, but since both the wolfstooth and race face 30T both have offset tapped threads, I think that moves the crank inwards more making for a more centered chainline. I threw mine on last night (nearly in the dark) but on the 36T cassete cog it looked like a pretty ugly chain line....

    Going 1x10 on Stumpjumper Comp FSR 29

    I've been thinking of doing this to my 2012 comp fsr. My main concern is being able to take the bike anywhere and still climb everything. I also ride a ss talus raleigh. That I climb everything with except the old school stuff I take only the stump to.

    I had no issues with it on my 2012 stumpy. I used stock cranks with a r/f 30t and normal 10spd cassette put well over a thousand miles or more on it like that with no problems.

    I coverted my 12 camber comp, WT 30 with non clutch XT derailleur. Works great. If I had to do over may go with a 32.

    Mine used 104 bcd spacing.

    And there is my dilemma, 30t or 32t... My regular rides are somewhat pitchy with some extended climbs. Usually ~5 miles on road to trails...

    Very cool ! So what are the particulars? Is this 30t front and ~40t rear expander? What type of terrain are you riding? Does it spin out quickly on pavement?

    TIA,

    It is a 28 with a 40 in the rear. I figured the 40 would be cleaner shifting than the 42. I was running the 28 up front in the past on a hardtail with just the 36 in the rear. I ride in New England. While our climbs are not always long, they can get steep and technical; bony and roots. While I do some flowy trails, most of the stuff I ride has crap all over the place, drops, etc. I realized a few years ago that the last four smaller cogs on my bike were nothing more than spacers, so I knew the 28 would work well and allow use of the entire range of gears. At a 95rpm, I am closing in on 20 mph in the smallest cog. The only time I go that fast is if gravity is helping me.

    I don't do pavement, unless I am on my roadbike.

    Thanks everyone I am gaining confidence it making the plunge to 1x10, just confused on a 32 or 30 on my 14 Stumpy 29 Comp. Some of my climbs can be pretty brutal but I also don't want to feel limited on my top end..

    Fantastic, this is the feedback i was looking for! Im going to start with a 30t with 11x36. If lower gearing is needed then expander to 40t. I agree that the shifting seems it would be smoother.

    I felt the same as you did, I live in Italy and do a lot of climbing. I ended up going 32 in the front and 42 in the rear. So far it feels perfect. I can top out about 24-25 mph easily on the road.

    On the trail I won't ever really go that fast so..

    I run a SS now but a few years back I built up a 1x10. I went with an E13 chainguide in the front, standard 34t chainring, and an XX cassette/derailleur. ZERO dropped chains. In hindsight I wish I had done an XO clutch derailleur to eliminate any chain slap but, regardless, no drops.

    Ok, so I was on the fence about this whole effort, bought some of the parts but had second thoughts and returned them convincing myself that 2x10 was the way to stay. Well I jumped in and converted to 1x10 and have to say what an easy project! I used a standard SRAM 1051 chain, Oneup 42t expander and a Oneup 30t chainring. All parts bolted on with absolutely no issue. While this was done last night, I have not yet had a chance to ride but I am sure it will be fine. BTW - I am happy to say that I shaved off nearly a whole pound and now the weight is 29.2 lbs. This includes heavier wheels (WTB Freq i23's and Reverb dropper post.

    If your on the fence, commit, you won't be sorry!
