    Stupid 1x10 questions

    I've been training recently on a singlespeed roadbike, and as such, found I'm using the granny less and less on the trails. So, to drop a little weight, I was thinking of doing a 1x10 setup. Right now I have a Shimano XTR med cage rear derailleur, XT front, on a FSA afterburner crank. My question is, do I need a front chain guide (read somehwhere you can get by without them...), and if so, can I just use the front derailleur during my trial period and just turn the adjustment screws in so it lines it (will it go that far?)? Also, do I just undo the bolts that hold the chainrings on, or is removing them more complicated than that?

    Yes I tried a search, just couldn't get the terms right. A 1x10 FAQ thread would be great..

    This is on a Alma 29er HT.

    Thanks!

    The front derailleur should work fine as a chain guide for your trial period. If you like it, I would suggest going with a chain guide where the big ring used to be (Salsa ring dinger works well) with an N-gear jump stop on the inside.

    You may need shorter chain ring bolts to put it back together...your LBS should be able to hook you up with the right bolts.

    I used a Paul keeper on an old rocky mtn element frame, but my new Superfly is going to require a front DR mount keeper, and I recommend getting one, I would drop the chain pretty regularly on singletrack downhill when you weren't pedaling.

    Other options include e13 XCX (various incarnations) and MRP 1.x.

    I used to use dog fangs or third eyes and an outer chain guard on my 1x# bikes, including 'cross bikes, but like the others have mentioned, the MRP/Paul/e13 style has worked much better.

    Old thread guys but thanks. Wound up using a E.13 XC guide. Selling all my old drivetrain stuff since I liked it so much and swapped to an X.0. short cage derailleur.

    I've looked all around and can't find one, probably because most don't need it, but does anyone make a keeper that would work with a small chainring on a bike that does not have a traditional round seat tube and therefore uses E Type mounted front derailleurs?

    For more extreme terrain riding on a big bike you need a small ring (24) but not a middle ring, unless you live in the mountains where there are long steep downhills. Then you really need 2 or 3 rings.
    No it never stops hurting, but if you keep at it you can go faster.

    BBG sandwich works well on my 1x9 and it's cheap. I don't believe it will work on a 2x10 crank though. If it's a 3x10 crank, you'll be fine.

    Yes, e13 makes an e-type version of the XCX guide

    Sorry, I forgot about that part. I don't actually know of any chainguide for any system that goes that small.

    I am going to do the same thing with an X9 short cage RD. What size cassette and front ring are you using with the short cage? Any issues?
