I'm contemplating going to a 1x10 set up, Based on some rough calculations and assistance from Sheldon Brown, I think the best front chain ring gearing for me would be 34 T considering I have an 11-36 cassette outback,  Any thoughts? what are you running? What brand of chain guide are you using? THanks

I'm riding a 1x10, with exactly that gear configuration, right now. It works well, though there are times, two hours into a race, when I wish I had a 32t chainring rather than a 34. I originally started with the Paul chain guide, but determined, after wedging my chain in that thing more than a few times, that it was overly complicated and doesn't function exceptionally well. Following everyone's suggestion, I switched to an MRP and have been thrilled with it.

I'm on a 36x11-36 with a e.13 XCX chain guide and ring. Never dropped chain. I've only wished for a smaller gear a handful of times but I'm generally very happy with 36 up front.
EDIT: to add I'm on 29" wheels.

I've been 1x10 for a couple years.  Up front is a 38 with an 11x36 in the back.  When I want an easier gear I think about singlespeeders and quit whining.  For me having more top end speed is more important than an easier granny gear.

I've used the paul and mrp chainguides but my favorite is the e*13 xcx-st e-type.  I also used to get a lot of chain-slap or the chain would come off if I back pedaled, but since switching to a medium cage rear deraillure there's better chain tension and it's gotten a lot better.

I'm on a 26" bike.

Anybody have any experience with the "Mattias Hellore carbon chainkeeper" this guy gives in his parts list (scroll down a little on this page: http://weightweenies...=674773#p674773 )? (Sounds like from his threads it might be British, since he said he changed countries.)

I've heard good things about the MRP too, but wonder if I should be shooting for the lowest weight (where I can) while still having well-functioning parts -- I still don't think I'll approach under 18 pounds like this guy did though!

I have seen several setups sans chain guide, just a short cage derailleur and plenty of chain tension.  I think if you combined the new clutch type rear derailleurs with a short cage you would be good without a guide.

Good point!  I love my new XT Shadow-Plus -- maybe I'll try it with a 34 or 36 tooth single-ring this winter, and practice with it enough to find out whether need to add a chain-keeper or not.

Personally, I wouldn't chance it. It might work great, until it doesn't, which for me I'm sure would be at the same time I'm having my best race ever. You'll save a few $ and grams by not using a guide, but the insurance is well worth it IMHO.

Truth.
