Has anyone here tried a 2x9 or 1x9 setup on their bikes?

Just thinking about options on my bike. I don't tend to use either my big ring or little ring on my bikes so thought it may make sense to have a go at two (or even one) ring up the front of the bike.

If you have tried it, how did you find it and did you have any setup issues?

I've got a 2x9 setup on my 5000, and as long as I'm on the East Coast, I'll never go back. (And I may never go back even if I move out west to bigger mountains). I love the extra clearance I get without the big ring. (I have a lightweight Shimano Saint bash guard). I don't miss the big ring at all. I took out a couple of links on my chain to keep it tighter, and I tightened the upper limit screw on my front derailleur to prevent it from dropping the chain, but other than that, no modifications.

I never thought of that. My 3 by 9 flops around to no end. Removing the big ring and a couple of links may be the ticket.

I used to do something similar to matno but instead of a bash ring we would use old steel chainring's

Excellent for climbing over fallen trees

Just finished a build on a 2005 Razorback. I will post pics as soon as I get a nice sunny day and time to snap them. I am running a 2 x 9 and I like it. See this link if you are interested:

Me and herself have been riding 1x9 for long time. We like the simplicity. A 28t (26t for her) chainring and BBG bashguard w/ 12-32 cassette. It suits our needs here in the Northeast (NY), USA. I really wanna use a 34t cog to make the climbs easier. I heard there could be (if not already) a 36t cog in future casettes. That'll allow for a bigger chainring, say 30+ and will be less wear on the chain. BTW, there's an extensive 1x9 thread in the "drivetrain" forum of MTBR.

you've got these on the cheaper models:

..hmmm, 'looks like a heavier 7-speed cassette from yonder. I see that on a lot of local delivery bikes w/ non-SIS thumb shifters. Big jump shifting 6 to 7 and probably not gonna be smooth going uphill..

I use all three rings on my bike, even though sometimes it is just the teeth on the big ring and a quick ratchet pedal move to go over a log I can't clear otherwise. I try to use a pedal to go over but if they are too high I have no qualms using the big ring to bite and motor over a log. When I ride hard surfaces I spend most of my time in the big ring and off road the big ring still has valid use, giving it up to put a bash guard on would limit me to about 20 mph while pedalling and I find that unacceptable.

My 110 lb. daughter races with a 2x9 Middleburn(27-40) front and 12-34 rears on her hardtail. Before that it was 29-40 with an old C-dale crank. Turns out that spinning anything lower than 27/34 is slower than walking.
You'd be hard pressed to find 3 rings at the races, Adam Craig won XC in '08 at Mt. Snow with a single front ring. I think it was a 36t!

Check out the gearing charts in "Zinn's", you'll be pretty surprised at what even 1x9 will get you- just gotta' deal with the gaps....

Her Turner (built ESPECIALLY to conquer Mt. Snow!) now runs 29t front (single ring) with an 11-34 rear. 25.6 lbs RTR with real heavy tires. Snow shreds lightweights....

I'm gonna' hang some SRAM XX on that sucker sooner or later for a 1x10 if the chainline works out.

P.S.; don't forget about the benefits of a short cage derailleur either!

See this link. White Industries makes a very nice 2 x 9 crank. This might go cheap.

Would like to see a 24t & 52 T chain ring set-up

....or the front derailleur that could handle it!

Well I've finally bit the bullet and will be going 1x9 next week with the 856 build. I just ordered an MRP 1.X chain guide. I'll keep you all posted on who it turns out.

I will be able to run anything from a 32 - 36 front ring and have an 11-34 cassette. That should cover me for most tracks.

The Paul chainminder is a beautiful and effective piece of work also if your seatube is in the right place.
