    xx1 w/xt derailleur on a superfly100 carbon

    I am going to pull the trigger on swapping my xt 2x10 for a xx1 1x10 on my Superfly..as long as I have owned this bike about a year I might have changed the front ring 2 times..I never use it..I am ready to upgrade and going with the xx1, Per sram it will work with the xt derailleur...Any one else run this set up?

    I run the XX1 crank 1x10 on my HT, currently using the X9 Type 2 but I am about to put it on my SF100 which is XT Shadow Plus. I run a SRAM 1031 or 1051 chain and an 11-36 XT cassette. The crank won't care what kind of derailleur you have as long as it's a Shadow Plus or SRAM Type 2. If it's not clutch assisted, chain retention won't be as reliable. I have run a 1x10 with no chain guide on my SF100 with a Surly 32t and XT Shadow plus with no problems.

    I'm not quite sure what compatibility you are talking about here. I mean the rear derailleur and SRAM shifters aren't compatible, and if you're going 1x on the front you won't have a front derailleur.

    additional - you'll probably need a chain keeper for the front ring.

    If you run an xx1 crank with a shadow plus or type 2 derailleur you do not need a chain retention device. The only compatibility issue here is the fact that you can't use a SRAM shifter for a shimano derailleur and vice versa. Personally I have never tried to prove or disprove the claim.

    From what I've read if you want to run this combo the best bet is to use the XX1 Crank and Chain with any 10 speed cassette and then a 10 speed shimano or sram shifter/clutch rd setup.

    How's the XX1 chainring working with a "regular" SRAM/Shimano chain? Should be fine with any good 10-speed chain. If you're running the Dynasys-level Shimano equip, I'd run their chain - plate shaping to work with their cog/chainring cut-outs. I used to run SRAM chains on Shimano back in the 9-spd days with a great track record of longevity and lack of chain problems, but the newer systems do seem to be pretty dead-on with their proper "system" pieces. Both brands rock. The XX1 is impressive with the thought that went into it on the crank and ring, especially. Do you think you'll convert to the XX1 11-spd in the rear some day or just stick 1x10 with the hybrid system? Be interesting to hear how it runs with the XT!

    If it wasnt so pricy I would do the full swap, I dont like that you have to swap the rear hub..and the reviews on the rear derailleur has been getting mixed reviews as well as the chain..Its not installed yet so I can not give a review on it, I should have it installed by Friday 3/8/13 & Ride over the weekend only because I am working out of town till the 11th

    Works fine as long as it's the clutch derailleur. I am running an XX1 crank (32t), XT cassette, XT shadow plus rear derailleur and a KMC 10 speed chain. Have yet to throw the chain even when plowing rock gardens or launching drops on my Rumblefish (which shouldn't be that much different than the Superfly).

    BB Part #

    Good stuff! What was the part/part number for the bottom bracket that you used to get the xx1 to work with the Trek bottom bracket? You had a shimano XT crank previously correct?

    I was looking for the SRAM part number of the delrin cups and bearings for the bottom bracket. The shimano cups and bearings are different from the SRAM ones. It was necesarry to switch the cups and bearings to get the crank mounted properly, was it not?

    Corbinwork,

    Did you use the spacer and wavy washer on your crank install or just the wavy washer? I have the old 3 ring gxp cranks off the 2010 superfly 100 on a warranty 2012 SF 100 pro and it needed a spacer on the crank next to the wavy washer to fit. I have the xx1 kit on the way with the 175mm gxp 168Q cranks and can't wait. I am running the XO 1x9 now, but everything has a ton of milage and it seemed better to get the whole kit than buy a piece at a time.

    FCuddy: Yes, Sram and Shimano use different bb's. Your bike is a SF100AL, yes? AL uses a pressfit bb, from Trek it's part # 419181 for Sram. The carbons use just bearings, part # 404700 for Sram.

    dlennard: Spacer and wavy washer were used on Corbin's bike.

    I called trek on a crank issue and they said that the carbon has press fit BB.

    Re: xx1 w/xt derailleur on a superfly100 carbon

    Mine came with a XT crank. Would that use the sram bb or shamans bb?

    All the Superfly 100 carbon do have press fit bearings BB95. Sram cranks use one kind and shimano use another so you have to get different bearings for different cranks and they both are sealed.

    Trek refers to the BB90/95 as "slip fit". Although you do literally have to press the bearings into the frame, they aren't what is commonly called "press fit", which consists of bearings in cups which are pressed into the frame like a headset.

    Blunderbuss, thanks for the response. I actually have a new Carbon SF100 Elite SL. You're saying all I have to do is tap/pull out the Shimano bearings that came on the stock XT build and install SRAM bearings and the XX1 crank will mount up? I am assuming spacer and wavy washer too? Thanks again!

    Yes, you just need to get the Sram type bearings. You may also need a Park BBT-90 bearing remover if you bearings are in tight. Sometime you can pull them out with your finger. You will also need a bearing press or can use a threaded rod and some washers or even tap in with a rubber hammer, but would not recommend.

    ^^^this. 404700 is a kit that includes the bearings, wavy washer, spacer, caps, and gunkguard. You need most of it. The 24mm id bearing (driveside), orange cap, and gunkguard are actually the same as used for Shimano. Be sure to install the gunkguard so that male part is on the driveside, or the nondrive bearing may not go in right. One last FYI since you said you have the SL: The 2013 SL Pro comes with the 156 Q factor instead of the 168 used on the 2012 Pro.

    Jeff,
    I was installing my new xx1 on 2012 SF 100 carbon last night and according to the Sram directions I should not use the spacer if my BB measures over 92mm. If I measure mine outside of bearing to outside of bearing I am at 94mm so I tried without the spacer, but did not torque all the down. It did not look like it would take up the slack so I put the spacer in and cranks on on, but does have some friction maybe do to new dust shield. It is hard to see the space on the drive side of the crank due to the recess of the new crank. Just making sure I need the washer and Trek did not change the width of the BB from the 2010 SF100 where the spacer was needed.

    2010 and 2012 are the same. I tried both ways and the spacer was definitely required. IIRC, the order was (driveside crank.spacer.wavy washer.dust cap.bearing.tube.bearing.silver cap.nondrive crank)

    Hey, Corbinworks,

    Did you change the rear derailleur? It looks like a long cage XT in the photo. Is it? Is it a clutch-type derailleur? I believe Shimano calls theirs a "Shadow XT."

    Midway through last season I removed the triple on my OCLV Superfly 100 and replaced it with a 2x10 26/38 XT set up. (changed the shifter too) Anyway, I had some issues with chain suck occasionally and a good bit of chain slap afterwards.

    After thinking about the situation a bit, I realized the long cage X9 that came with the bike was too long for the new smaller chain rings, which caused some of the sucking (my bad for some it too!) and a bunch of the slap.

    Today I ordered a new Type 2, medium length cage X9 derailleur. Sram now makes a clutch-type derailleur. This should help reduce the chain slap almost entirely and help the chain suck (if I don't rush my shifts!).

    I bring this up because I noticed in the photo of your beautiful new XX1 crankset that you have some scares from chain suck and slap.

    I installed the XX1 on my 13" SF100 SL Elite. I did not use the spacer on the drive side crank per the instructions. I went with wavy washer-seal-bearing. I torqued it to spec and it seems good. No play and it spins freely. Is there any reason to use the spacer on the drive side if there is no play? Jeff, I know you mentioned it was necessary on the 2012 SF100 carbon bikes.

    I have installed a XO type 2 & yes the marks on the frame were from the XT crank set up..I have had zero fail from the XX1 & XO type 2

    IIRC, it was obvious the spacer was needed, so if all looks good, I'd say you're probably ok.
