It's the wave of the future. Simple, reliable, lighter. It has made me a better rider since I don't worry about getting my chain to drop into the granny gear on climbs. I just pick a line and hammer. It makes me stronger and more efficient without the knee-busting efforts of a singlespeed. Without the extra rings I can run a shorter chain and get a lot less chainslap. And there is nothing I hate more than trying to get a front derailleur to stop rubbing.

I built this up over a few months by scrounging for good deals on lightly used parts on Ebay and buying OEM take-offs from JensonUSA. I got my hydroformed aluminum Planet X frame, King headset and Thompson seatpost from Ebay for $220 total. So far I've bought every part except the fork and wheels for ~$700. Retail would have been over $1500. I should end up saving about a grand by building it myself. I built it like this because I'm north of 200# and ride the very rocky and rooted trails at Turkey Mountain in Tulsa, so durability was a priority.

Truvativ Hussefelt crank, 32T with aluminum bashguard, 22T removed. JensonUSA takeoff- $69
Truvativ DHLT BB, 113x68. JensonUSA takeoff - $19
SRAM PC-991 chain, solid pin. JensonUSA pricematch - $26
SRAM X-7 rear shifter, JensonUSA takeoff - $30 for pair. Would have liked the X.0, just needed something to work with the X.0 derailleur for now. Still works great.
SRAM PG990 11-34T cassette, the new red one. New in box from Ebay - $75
SRAM X.0 Long Cage derailleur. Barely used on Ebay - $100
Nokon cable housing ~$45 for front & rear, BlueSky Cycling
Jagwire teflon coated cables, BlueSky
NGear Jumpstop - $9 at LBS - absolutely necessary unless you enjoy stopping every 5 minutes to put chain back on the chainring.



Now let's see your setups and tell us why you chose your components.

How About 1x8?

44T chainring and 12-25 cassette all Campy drivetrain.

I had to run it 1x for a while while I was waiting for replacement chainrings. Middle rings are tough to come by. It wasn't much of a climber but but it was a good warm up for cyclocross (ie having to run up steep climbs).

Not That Bad

It's on par with the gearing most of the SS crowd runs.
44-25 = 1.76:1
2:1 is fairly standard SS gearing

What do you mean 'rub bad' ?

When you're in the big ring in the front and back; it usually stretches the chain to the max and creates an extreme angle across the gears. It wouldn't be as bad with a 25T in the rear as it would with a 32T.

Well Technically....

...it would be the same. The 25T and 32T would be in the same position on the cassette body so the angle would be equal.

However I ran a shorter BB temporarily with the single ring. This shifted the 44T in where the middle ring would be therefore giving me a pretty good chainline and allwing the use of all 8 cogs.

I went 1X9 a while back and love it. 05 Specialized Enduro Expert...

Extralite 30T CR
Spot Brand Ringguard
N-Gear Jumpstop
XT Cranks (tuned)
XT Med Cage RD (Tuned with Ti and XTR parts)
XT 11-34 cassette
Sram PC-99 chain
Crank Bros 2xTi pedals
Answer Pro Taper carbon riser bar
FSA XC115 stem
ODI Oury grips
LX shifter pod (tuned)
Juicy 7 brakes (stock)
Chris King/Mavic 819 wheels
Fox 36R Talas (stock)

new rear shock should be in the mail (DHX Air) because my 5th Element died this past weekend

everything on my bike was chosen to reduce weight or increase strength. i weigh 200lbs and ride hard, but climb LOTS. going up then going down is what we do so, light to go up, strong for fast hard decents. i freaking hate FD's and i hate trying to tune them. besides the frame looks so much cleaner now. i only own one bike so it has to do everything for me.

she is still a bit heavy depending on tires. just above 30lbs with Kenda Cortez 2.4's. she is a bit heavier right now with a Kenda BG 2.35 on front with a Maxxis High Roller 2.35 UST tubeless on the rear (don't know exact weight).

i could drop more weight by milling/drilling the ring guard or tuning the right shifter (i did a bunch of grinding and stuff on the left one that came off as an experiment and lost 60g or so). the seat is rather heavy as well as the grips, but i sort of like their functionality. longer seat lets me move my weight around on the climbs and the grips have a really nice solid feel to them.

i like your setup too. i would probably have a lot of pinch flats if it weren't for my 6" of rear travel though!

i do hope to build a new bike this year. i hope to get a 29er (with full gears) for when i ride with the cardio freaks. it seems that riding with those guys with this bike is a bit of a handicap :) they all have carbon framed super light fully geared XC machines. needless to say i struggle to keep up with them on the climbs and fire road ascents. (i make up some time going down though)

Been riding this for over 2 years now. I've only dropped the chain a handful of times and it has always been in a crash, never while riding.

Forgot to mention 36T non-ramped chainring, 11-34 cassette. I live and ride in Colorado and have never run out of gears. Love 1x9 so much that I've convinced my friend to convert on his new build.

Hacked up LX front derailleur to keep the chain from dropping

Heres my 05 Cannondale Prophet. I upgraded my crankset to the Shimano XT and decided it was time to give a Bash gaurd a try, while I was at it i took the Front D of and ditched the granny ring figureing it was time to get strong. The bashgaurd has allowed me to do a lot more, it is so fun to crash over large logs. The plastic E.thirteen slides ride over the logs, very cool. So far i have been doing allright without the granny gear.

I used the Jumpstop, the the chain has held on pretty well

I have a SC Superlight 1x9 with an old Raceface taper crank and Spot 34t ring, don't use a Jump Spot and chain drop has not been a problem on this bike for almost 3 years. My old heckler needed the JS or the chain would not stay put.
Really like the extra ground clearence and clean look of 1X, and I never used the big or small rings anyway.

Loving' the 1x Set-Up!!

I converted my Chester to a 1x8 set-up. Removed the smallest cog from the cassette because the Boone chainring I am using was built to sit in the 'outer' ring position and by adding a spacer behind the largest tooth, I was able to improve the chainline. My Smoothie is set-up as a 2x9, likely to also loose the smallest cog to lessen the cross chain effect. Here's the complete build.

Matt Chester Frame ( I believe the only vertical dropout Ute he ever built)
Fox Vanilla RLC fork
CK Ti headset
Moots Ti Seatpost and Riser Bar
Seven Cycles Ti stem
Wheel set (f) Phil Wood Sl disc hub/supecomp/Dt 4.1d
(r) CK Classic/supercomp/Mavic 3.1
Phil Wood Ti BB
Avid BB-7 (f) brake Avid Ultimate Vee (r) with Avid Ultimate Levers
Boone Ti SS Chainring (31-tooth)
Cycle Dynamics Ti 13-34 cassette
RF Turbine Cranks
X.0 Rear Derailleur and Twist Shifter

Here's mine. It's an '05 Voodoo Bizango. I picked up a 32T salsa chainring from my local REI and got an NGear jumpstop, and I got a bashguard off of ebay. I run a 11-34 cassette. It rides like a dream and since converting it 9 months ago it's been maintenance free. I hated that front der.

wow.. both of those last two are very beautiful bikes. nicely done.

MTB dad... i can't believe that you don't have problems dropping the chain, but whatever you did to keep it in place, congrats. it is so sweet and clean without the N-gear. do ride hard through rock gardens and such?

I am running a...

jump stop, just not the guard. The chainring is a Boone SS ring, so it is unramped and the teeth appear to be slightly taller than a 'standard' ring as they were never designed to allow for the chain to move. The removal of one cog and the subsequent moving of the rest of the cassette 'outward' seems to keep the chainline pretty straight. I don;t ride a lot in the way of rock gardens here on Long Island, but we do have our share of root gardens that will chatter your fillings loose and knock wood (knuckle to head) no issues yet. The RD is a medium cage and I run the chain as short as possible. In the process of planning my next 'project' which will be another 1x8, probably a softtail.
