    1x10 from scratch, input on components.

    Been searching and reading alot on going 1x10 for a new hardtail build and think it would be optimal for what im looking for. Would be running 32t ring in the front, 11x36 in the rear. My questions are as follows:

    Is a singlespeed crankset my best option for chainline etc., like xx1?
    Seems if I don't need a 2x10 there's no point in buying 2x10 just to convert it to 1x10.
    Any negatives to running xx1 crankset 1x10?

    Ive read some people have been using shimano / sram parts together.
    Can I run xx1 crankset with XT shifter, derailleur, chain, and cassette?

    If I run xx1 with a type 2 or shadow + rear d, with no chain guide, does the clutch need to be on all the time to prevent chain drop?

    If you were building a hardtail from scratch and wanted to go 1x10 what components would you use for the best lightweight bang for your buck?

    Thanks guys.

    After more research I found you can definitely do the xx1 crankset with shimano components like XT or XTR. So now I'm wondering if there is any other singlespeed focused crankset that is worth checking out over the xx1. If I was to convert a XT crankset to 1x10 does a double or triple work better?

    I converted my 26" hardtail to 1x10 from 3x9 for this season. Only six trail rides to date, but so far, no slips, slaps or sucks.

    Here is what I'm running:

    • SLX triple crank with the chainrings removed
    • Race Face 32T Single Ring non-ramped chainring to replace the stock ramped 32T middle chainring
    • Race Face 32T Atlas bashguard
    • n-Gear Jump Stop chain guide
    • Shimano SLX HG81 10-speed cassette, 11-36T
    • Shimano Zee M640 rear derailleur, FR version (25-tooth capacity)
    • Shimano Zee M640 right (rear) shifter
    • SRAM PC1051 10-speed chain


    Obviously, there are a million ways to skin a cat. The above is just what I have experience with.

    I'm very impressed with the Zee. I believe it was designed for single-ring drivetrains. However, I have read of folks on full suspensions experiencing difficulty getting their chain tension just right.

    You can definitely run XX1 rings/crank with any 10-speed components. You could also use any crankset with 104 BCD and one our our Drop-Stop chainrings. Either way, you won't need a chainguide or jump stop. If you ride with rocks, etc. you will want a bash ring for sure -- difficult to do with XX1 but easy with a 104 BCD crank. If you want a frame-mounted guard, it should work with either. Check out our website and look around more on the forums. Regardless of how you do it, 1x10 is a great choice.

    I'm doing a highball. So far I have an XX1, 32 crankset. Planning to use XT for the rest. Trying to figure out which parts exactly and RD length.

    I just put 1x10 on my Yelli Screamy. Only 2 drops so far and they could have been just been bad luck because neither happened in a rough area. I plan on getting an MRP guide soon just for insurance that it doesnt happen again.

    These are my parts
    -SLX 175mm 3 ring crankset from Jenson - $89 - 654g with only stock 32t ring
    -XT M780 Shifter from squarebikes - $64 - 143g
    -XT (SG) Shadow Plus rear derailleur from Jenson - $84 - 257g
    -SLX HG-81 11-36 cassette from ebay - $25 - 366g
    -KMC DX10SC Chain from amazon - $25 - 254g

    Hope this helps..

    XO bb30 crank with NSB spider
    Wolf Tooth 32 ring
    XT Shadow Plus rear derailleur
    Sram X9 9sp shifter
    990 Cassette 11x34

    Using X9 shifter and XT derailleur? How is it working? Short cage?
    I'm thinking of going 1x10 on a new build and have a rear X9 shifter and would like to run XT rear derailleur with a 32 ring and 11-36 cassette.

    Other crank options for 1x that should be considered?

    The Sram 9sp shifter supposedly shifts a XT 10spd derailleur on a 9sp cassette.

    I am still waiting on a few parts.

    I have tried the same thing, and using 9 speed to shift 10 derailleur is no better than OK *.

    I would not put too much effort into making it work, my wifes new 2012 sram X5 (10speed) runs and hides from my 2009 x9. I have no idea what even could make an x0 -function- better than her x5. The thing is perfect. A pair of the x5 shifters brand new is $50. (i don't know if you can buy just one)

    * as many may know, the biggest problem with sram rear derailleurs is the large gear screw confuzzling itself with limiting the small gear travel

    Just get a much cheaper xt crankset or use one you have laying around. I have looking at 1x10 also and I found that a company called wolf tooth components makes a chainring like the xx1 for use on standard cranks.

    Everyone limits 1x10/1x9 because of 104BCD chairing.
    For someone used to 22x32 (for example) it's a huge leap and it means you need to be in shape!
    I'm using a 28t chairing (XX) and an 64 to 80 adapter on one of my bikes
    Price?
    A XX28T chairing and some time on the bench!

    Sorry for the poor pictures. Need to take more detailed ones.

    It's ok for off road with a 32/11.
    And if you got a 36t rear cassette it would give almost the same rate as a front 24t x rear 32t (+/- since the true ratio would be 24x32 = 28x37) - except for the heavier gear (that I don't use on Trails.....)

    It's cheap
    It's light
    It's OK for most rides (Exception made to +30km and +1000m altitude gain!)
    On the road it's very slow!

    After some miles, I think for all kind of riding it would be better to have a 2 ring upfront (with a cassette at the rear) with some kind of electric derailleur.

    You could have a small shifter (kind Alfine electric and if it would be possible - squecial with no need to think about FD / RD!) and drivetrain would be more smooth in terms of power
    Then we could have an excuse for being last on the uphill: "Low bat problem"
