    Recommend me a crankset please ! :) on the chili

    So im REALLY trying to do a 1x10 setup once my frame comes in . I was thinking a 2x10 setup but i never really used the granny gear on my other AM bike and i was using a 36T chainring . I feel you guys would be more helpful here then another part of the forums

    So i was thinking a 32T chainring but what crankarms should i get that has the 73mmBB width ? My budget on the crankarms would be $500. Im really thinking about maybe some carbon crankarms or should i stay away from that?

    Again , this bike will be used for AM riding , i will try some lift assisted days on the NOT so rocky stuff but im sure by then ill prob be buying a downhill bike on the side .

    Im really trying to make this build my last AM bike that will be strong and not too heavy so i dont mind splurging a bit , i got plenty of time anyways till my right arm gets moving again.

    Running the Race Face SixC carbon cranks on both my Delium and Chilcotin. Work great. 73mm width is pretty much the standard and probably in excess of 99% of MTB cranks are that width. The only notable exception is 83mm cranks which are typically on DH and some FR bikes.

    You can run it with other chainrings if desired.

    I much prefer the spindle interface on Shimano cranks. They are easier to get on and off. I thought I read somewhere that RaceFace was changing their interface though, but don't have any experience with it.

    XT cranks are the ticket for me. Super dependable at a good weight.

    XO's with a MRP bling ring and the race face end caps. Been running them all summer and love how stiff they are.

    Seems like the XOs have some nice low weight to them . I was planning on running an E-Thirteen chainring , i been using their stuff for a while so i love them . Hmm , this might be the winner for me here .

    Just FYI, my buddy just snapped one or two of his chainring tabs off his carbon RF cranks. And yes, he used the RF spacer/washer things under the bolts and they were torqued correctly.

    If you want light, XTR's are only a hair heavier than the RF. Sicklines say the RF are 492g, and the new XTR are 526g.

    I'm not ashamed to say carbon still freaks me out on a mountain bike. But then again, I run Saint cranks on my Chili....

    Good to know , i will keep that in mind . Is there some type of warranty that will cover him for just " snapping " his tabs? Im sure its going to be a PITA process ...

    Ha ! I wouldnt mind Saint cranks but they seem like they might be too heavy , i cant find out what their weight is

    I'm not sure, but he's got them going through the RA process.

    Some weights, crank arms only, no rings, bolts, all 175mm:

    XT m780: 616g
    SLX m665 (version with steel pedal inserts): 640g
    Saint 810: 759

    At a minimum for me I'd run SLX for steel pedal inserts and the beefed up spindle over the SLX M660 version. But I like the Saints and honestly feel they are stiffer. Maybe it's psychological, I've no idea. But also I'm 215 geared up and tend to push taller gears, and don't spin a ton.

    Plus the Saints are black, so they have to be better right? LOL


    Edit: one more thing, the beefier the crank gets, the more spindle interface you get where the non-drive side crank arm slides on the spindle. Just estimating for instance, I'd say the XTR has about 1/2" of interface, the XT/SLX about 3/4" and the Saint almost 1.0".

    RF SixC - Been fine running on 2 years now including some lift serve, many pedal smacks in New England rock/granite garden riding. I'm heavier than most.

    XTR - Stiff, probably as light in a 1x as the SixC with booties on. Have Two sets of new XTR (1 3x and 1 2x) Happy as a clam as well. Have these on my Chili, no issues with 5 days of shore and whistler riding.

    Can't comment on X0.

    Maybe... I was not able to run a Shimano chainring on my new RF Atlas cranks. The Shimano had more material surrounding the bolt holes than the a standard chainring and it wouldn't fit on the RF middle ring slot.

    For what it's worth, the 2012 RF interface was super easy--you just keep torquing until you bottom the bolt out (I used an old handlebar over my socket wrench for more leverage). The one time I needed to take the crank off on the trail was difficult, but I got it off with my multi-allen key tool so it is possible (although I had to re-tighten it when I got back home).

    I like the RF interface much more than the Shimano which tended to loosen up on me once in a while.

    I didn't know Shimano made backward compatible chainrings... I think the OP was asking about non-RF in the sense non-Shimano can be difficult with XTR level so can you run an e13/MRT/Homebrew/etc chainring...

    That's the exact same setup I wish to run , and hey it gives you a good workout on the climbs .... Sorry to be a bother to you but can I run my own chainguide ? Or does it have to be MRP to accommodate the MRP chainring ?

    I think there would be no problem running any type of chainguide. I just went with the MRP so when I get stronger I can run up to a 36 tooth chainring with that chainguide.
    I ride a lot of rocks here so the bash guard has been working good.

    - I have really liked my X0 cranks but I HATE how they hook together. It makes field servicing impossible.

    - I really like the XT and XTR method of joining the two sides. It's super easy to pull apart and make replacing chain rings (or chain ring bolts) a breeze.

    Interesting comparison from the RF site: http://www.raceface.com/comp/pdf/XC%20Double_RF.pdf

    The spider looks clean for a 32T single ring setup

    Ive broken three sets of SixC- cranks during past two years. Two of those are warrantied, one waits still shipping ... Always broken tabs, no other problems with those.

    Used / using several different cranksets in Chili (1x9) and in my full-rigid singlespeeder and after using SixC`s and X0 DH`s with HBC chainrings (there`s a small crack in those too - circular one in area where driveside crank joins to axle...), ended back to old XTR M-970`s. Nearly as light as carbon ones, practically as stiff as carbon ones. Those requires special tool for removing, but that`s the only negative side.

    Dont say no to carbon in mountain bikes - Im using carbon handlebar - but no more carbon cranks for me.

    I have the same crankset with the intention of converting it into 32T single ring setup for my upcoming Chilco too,

    Broken tabs? How the heck is that happening? I'm not very light and I've had no issues slamming away on the SixCs for over a year now. Has RF given any feedback? Just curious so I can look out for it, no flame/trolling here.

    pergamonx is the extreme tester on everything. He pedals more miles in sub-freezing temps than I do all year. I'm always glad to have him chime in, because if it works for him it is guaranteed to work for me.

    Just say no to single ring set ups with ramped and pinned chain rings. They will work fine, but a non-ramped and non-pinned ring will have more positive contact and feel, especially when things start bouncing around or you ratchet the pedals back to clear something.

    I have old xt cranks and an e13 32 tooth chainring (non ramped and pinned) and run 1x10 with the mrp mini g2 sl cgain guide. Works well. FYI any chain ring designed for 1x will not be ramped or pinned. The shimano / SRAM rings designed for 2x or 3x cranksets will.

    Yep - broken tabs. Heres one example - others have been ~similar ones - one or two tabs just break.



    All broken cranksets have been 2010 or 2011 models, those new ones yet in package are 2012 model; Ill suppose RF has strengthened those tabs- have not checked that.

    Im rather light, riding weight is ~75kg and honestly Im not sure when or how they have been actually snapped - have noticed those breaks afterwards when looking after some squeek or knocking from drive-train...
    Have used taco-style bash, always, so no direct hits to chainrings. Cranks has got hits, of course. And it`s not question of chainrings, have used many different ones (except RF originals) and that has happened anyways. No over-torque, RF spacers have been in use. Only feedback Ive got have been new cranks, but Ive not handled those warranty cases directly with RF, but via resellers.

    TSC, it`s your fault that my keyboard is covered with bursted beer : )

    Its true that our conditions here are rather tough for parts 5 monts per year. Someway it`s extreme, but Im not. My riding is about in the middle between N Vuilloz and Winnie the Pooh. And Ive more bike parts and components than frames, and it`s only fair to give a chance to every single part to break ... Btw, just realized that all those breaks in SixC`s has happened during summertime, so it`s not either question of low temps.

    Alright it toke me sometime since this new XT cranks requires a T30 torx wrench,
    From the picture below, a 32T is tight as the chain may hit the tip of the spider arm,
    Probably a 34T would fit better,

    What I am saying is that the 3x10XT is a better choice over the 2x10XT since the spider are similar to the older version which works well with a 32T rings

    What type of derailleur are you running with this setup? Medium or Long cage?

    I'm looking to mirror this setup on my Chili, except using RF Chester 175mm cranks.

    I'm looking to mirror this setup on my Chili, except using RF Chester 175mm cranks.
    I'm using a medium cage X9 with 34t ring and 11-32t cassette. Works great, but I'm looking to switch to a short cage soon.
