    Anyone ride a fixie 29er?
    Intrigued by an ad/review in some mag, can't remember where: the cog is bolted to the rotor mount and you flip your wheel around. Front brake only of course. While I've never done a fixed gear roadie or otherwise I was wondering your thoughts on this. Pedal strikes would be horrendous I'd imagine, and you couldn't go very fast down, but it'd be fun for the engagement right? Or more frustrating than enjoyable?

    I haven't witnessed it firsthand, but if you or anyone else does - please get video of the crashes. I'm not sure what the crashes will look like, but they sound like they'd be awesome - especially if the rider unclips and throws both legs out wide on a downhill to just let the pedals spin out before disaster strikes.

    Kind of what I was thinking. Still may give it a try though...

    Riding a fixed gear offroad really isn't as complicated as you'd think. After a while you can time logs, and even level your pedals when you rear wheel is in the air. In the Winter it has an almost traction control effect.

    I agree, fixed mtb is not as difficult or insane as most think. It's a whole different style of riding, but yes, you can still go real fast, yes, you can still ride techy singletrack, no, you don't go crazy out of control fast on descents.

    My fixed mtb is a 26" bike, but I may throw a Tomicog on my Monkey one of these days and go 29er fixed.

    I don't know why you would want to bolt a cog to the rotor mount as it's just a easy to build up a fixie hub for a mtb. One of the guys in Austin rides a 29er fixie, old link here...

    Ridden with him a couple of times and seems he can clear almost everything out on the trail.

    Well, I already have the disc/ss wheel. That's a pretty good reason to bolt a 30 dollar cog on and be done with it. I don't run a rear brake on my fixed mtb, so it's not like I'll need the disc brake.

    It has allowed me to have some fun on rides that had become pretty boring and forgettable due to sheer repetition. It gives me a new way to train as well. It is an easy switch if you already have a single speed and can live without a rear brake for a ride or two.

    Good point, but I think I'd like to still have a rear brake even if I went fixie just to make controlling the rear wheel a bit easier.

    Rode fixed off road for a good 5 years, about a year back on a freewheel. Fixed is fun, and there's definitely a rush to cleaning really rocky, technical stuff without coasting. What I've found, though, is that coasting can be a lot of fun too.
    I'd been told that riding behind me at Big Laguna was like watching someone pull out of a spectacular crash, for 2 hours. Riding a freewheel again makes a lot of the stuff I ride less dangerous, or at least seem that way.
    FWIW, I was using 32x16 both in SoCal and here in Texass after we moved.

    I've been riding fixie for the past two winters, but not the rest of the year. It adds a little spice to winter riding, especially on long boring snowmobile trails. I still have trouble crossing some rock piles and bigger logs, I haven't perfected the technique of spinning my rear tire yet to "clock" my pedals. Pedal strikes are common, so if you have a purdy set of cranks you polish every night, swap 'em. Crossing skinny bridges is a challenge also because you can't coast and focus solely on your balance. The real reason I started was you still have a chain to stop you if your brakes fail from ice. All that said, I may go back to coasting next winter. My $.02 fwiw.

    Yep...that's my buddy Todd....AKA Fixey Todd...

    I was with him on his first ride....with NO brakes!!!

    He rides eveything, the dude is way bad. It's tuff to keep up with him on his On-One Inbred 29er.

    Gets lots of looks for sure.

    I'll tell him about this thread.

    I love riding fixie 29er off road.

    Been doing it for over a year, logged about 600 miles off road doing it.

    Its the best, it takes riding and makes it artistic.

    Nothing climbs like a fixie. nothing accelerates like a fixie.

    in 600 miles I had one pedal strike and I use 175mm cranks.

    Its all about rhythm.

    I stared with a tommicog, then built up a eno hub.

    I love it, adore fixie riding its the best, IMO, and YMMV.

    you'd be surprised what you can do with just your legs. Something like 80% of braking power normally comes from the front anyway, so you really don't lose much at all.

    A bolt-on cog is a really good way to try it out and decide if you like fixed off-road, even if you do want more control down the road. The difference between fixie with and without a rear brake would be nothing compared to the difference between fixed and freewheel

    Yes -
    I enjoy riding fixed off-road.....more so than on-road.
    I mount a drilled cog to the disc mount. Takes a tungsten carbide bit with cutting oil.....or just buy a Tommie cog. Pedal strikes happen, but after a while you know when where and how much! I've been riding fixed off-road for a couple years - gotten many miles under belt.....cause that's the only bike I ride :)

    Like Motopail said - I first rode brakeless, don't try - you gain nothing.....and could loose everything :madman:

    I've always been curious about trying this out. The Tomicog is the cheapest way to figure out if you like it or not. One of these days I'll have to try it. Trails around here seem pretty fixed gear friendly.

    I rode fixed CX all last season, it makes mild tech sections more fun, and pedal strikes were never a huge issue as you can skid the rear wheel for a foot or two to avoid strikes, they do still happen pretty often though. . . I just finished up with a SS 26" to ride free this season, as well as the fixed CX.

    I was briefly without a MTB last summer so I rode my fixed cross bike everywhere. I was really proud of myself when clearing technical sections. It really brings a new challenge to trails that were otherwise not difficult to clear. Fixed trail riding really wasn't that hard once I learned a few basic techniques. One technique that helped me more then anything was learning to just ride straight over obstacles instead of weaving around them. This helped me from clipping my pedals in most situations. I already knew how to "hop and skip" my pedals backwards to get my feet in the proper position but honestly this rarely helped me and doesn't work too well in many cases. Just a few things that helped me...

    I didn't really feel that riding fixed held me back, but the road drops and 32mm tires that I was on at the time certainly did. I now have a 29er that I want to ride fixed but haven't gotten around to it yet. I think it's time to get the ball rolling with that. I still ride the fixed cross bike, but mostly on pavement and some gravel. It actually has a better build now for riding off road then it did before, with mustache bars and wide 35's.

    I've been riding a Karate Monkey fixed for several years now. I had ridden a loaner track bike a long time back and knew I liked fixed - so I built up a wheel on a Surly flip/flop hub. I got a screw-on disc brake adapter so I could have a rear brake, but this required mods and would unscrew if you tried to hold the bike from rolling backwards. I upgraded to the Surly fixed/disc hub last year so I've got full disc brakes now.

    I note that I hardly ever use the brakes, but when I do I believe that they are worth dragging around the rest of the time. My preference, YMMV.

    MtFx is very fun for me. I mostly ride flowy trails but have done chunky/techy stuff - just takes more technique, and is part of the fun to learn. I really love how I can regulate speed by resisting a little to set up for a turn/drop. When I'm riding my FS gearie, the process is; stop pedalling, pull brakes, modulate braking (overdo it, skid, release, etc) vs just resist the pedals a little. There are several places where I can catch air along the way - you just have to learn to keep pedaling while in the air. The hardest part of downhilling is staying on top of your gear - not letting it get too out of hand.

    Don't try it w/o brake(s) - you can throw your chain over rough terrain especially if you're still running a ramped chainring.

    Disc/fixed cog is an excellent way to start. The main reason I like to keep a rear brake is because it is more difficult to get your weight waaay back to avoid doing a stoppie while madly resisting the pedals. DAMHIK. Part of what you learn is to think a bit further ahead as you ride, because if you have to hit the front brake that hard - you will have your rear wheel off the ground.

    I run 34x20 or 34x19 normally - depending on my condition and trail. I have run 34x18, but haven't been able to get on top of that gear (yet).

    I spaced my track wheel out to 135 to use it on my mountain bike. This was at a winter 'cross race, but it's fun in single track as well. I still don't think a fixed gear can be beat for muddy conditions

    I have a brakeless fixie 29er that I mess around on.
    32/18 is the ratio I use.

    Actually, this is the only bike that works right now.

    Heyyy--I saw that bike for the first time last weekend (coincidentally, just a few days after I built up a 29er fixie).

    Props to Mike's sick fixie skills!

    I won't be riding my scorcher in a group any time soon, but he had no problem keeping up. . .on what I would call fairly techy singletrack (lots of log crossings, some sketchy descents).

    Yes, for a couple years now.


    One of the first times out. (This is university ag land, no trails harmed, just mud and cow $#!+.)


    The other extreme, less than a quarter mile away. And 50 degrees hotter.


    Spring time.

    I've been riding my Karate Monkey fixed off-road for a better part of a year. Prior to my awareness of Tomicogs, I had Boone make a Ti version of the disc mount cog. I tried unsuccessfully to drill out an old steel cog. Didn't work well, so I went with Boone and had the bike set up as a commuter for quite some time.

    After re-reading several posts on https://www.63xc.com/, I decided to try my hand at fixed off-road. I generally don't run really sketchy stuff or epic length rides on this bike. However, none of our trails are close to what you might call cart paths.

    Like many have done, I run higher than 2:1 at 36x16. The ratio was dictated by a few things. The cog I have was purchased with the idea of fixed commuting. I ran it @ 42x16 as I have my previous road fixed gear bikes. I lucked out in that the cog has a perfect chainline with the ring in the big ring position. Knowing that I would run fixed on-road, that I might run fixed offroad in the future and that I desired a 165mm crankarm, the Sugino 74/110 fit the bill perfectly. I can't remember the model number I have, but it's essentially the same as the 600 series and has forged crankarms.



    I run a Surly steel chainring in the outboard position. I just noticed they make a 34t chainring for the 110 BCD. I might try that in the future.

    Anyhow, I run no rear brake which sounded crazy at first, but I don't really miss it. Timing logs and drops still demands concentration, but despite all my buddies stating otherwise, I haven't wrecked yet. In fact, I am quite a bit stronger rider especially on climbs and have conquered many that I thought were impossible on this bike.

    People always tell me first that I am crazy and then ask me why. I like to reply that with a busy job, two kids, etc. I am pretty restricted with my adventure travel. However, I can ride the same trail back to back from my FS Lenz to a fixed, rigid KM and have a much different trail experience.

    Disclaimer: I rode a fixie on the road for 5+ years beforehand.

    Here's a pic in early commuter mode:

    This is Louise the Fixie Pixie. She's been at it since 05 and has one of Tomi's original attempts at the Tomi Cog. One hole was miss-aligned and I've been running it with 5 bolts since the beginning

    She's a mostly winter machine. Normally run 29/26. 2' logs aint no thang. It's one of my all time most favorite things to ride!!

    Don't fear the direct drive!

    When I had my Outcast, I took advantage of the flip-flop hub and rode it fixed for a little. Fun, interesting, not as hard as people think... but not worth writing home about.

    You have to be in the state of mind that you're not going to be flying downhill at incredible speeds. Riding fixed mountain feels like "hiking" on wheels, if you can picture the feel of that.

    On my SS CX bike, I can also flip the wheel on that, which I may do later in the dead of winter for some training rides.

    I also believe a rear brake is a good call. I actually used mine quite a bit on the trail. Again, whatever floats your boat, but I'm all for using a rear brake riding MTBs fixed.

    Since I've got a couple of 29ers I am curious how it would be riding big wheels fixed offroad, I suppose it would be a bit harder to decrease the speed - which normally is a good thing about those big wheels. I guess I'll get one of these bolt-on cogs in 20T and try. Currently using 32/18 on the 26er. I really like it and it is the bike I ride most since about a year.

    +1 for Tomi Cogs. I run it on a rigid 69er and have stripped two track hubs in the woods, one speed checking in a rock garden, and the other when a stick was introduced to the drivetrain that locked it up at speed. Both hubs were name brand hubs made of quality metal, it was just a matter of using a product not as intended. Since switching to the tomi cog, I have a lot more confidence about being able to control my speed without something stripping out.

    Nice. Good job, you captured the fun, some of the technique, and a little bit of the zen crazy of being committed to pedaling as the rear wheel drives you in places. :thumbsup: :cool:

    Another Singular Swift.

    I've ridden this as geared, fully rigid SS and hard tail SS and now it is time to try this.

    It has a bolted on Velosolo cog (15t) on Paul's single speed hub, 45mm Panaracer Firecross tires, and inverted Felt "alt"/moustache bars (I tried to create kind of like "pseudo drop bar" feel...not sure about that yet though. Slightly narrower flar bar would work well too?)

    This is going to be my winter commuter/"monster cross" type of bike. The idea of hitting techy trails with the direct drive scares me...but you never know? :)

    I currently ride a fixed 29er, but have been wondering about gearing choice for 60 mile races. On freewheel I would use 32/19 and am running 34/18 at the moment fixed which seems to give a reasonable balance between the dreaded downhills and being able to ride up the other side as well as technical sections.
    What is eveyone else running compared to their freewheel ss ratio?

    i occasionally ride my se stout fixed with a tomicog, lotsa fun...
    when i do it makes me glad that i kept the v-brakes on it!

    saw the Mr.Bee fixed gear dirt trail video in the ss forum yesterday & now i just noticed his post from last sept. it's inspired me to try-out my 700c fixed bike on some easier trails, i have the wheels off right now to change tires.

    wish me luck :cornut:

    One to two teeth LESS on the fixed cog than freewheel, using the same front chain ring. I do not race,

    700c fixie
    I have a couple hundred trail miles on my fixed CX bike. The bb height is pretty low and petal strikes are hard to avoid. I have gotten pretty good at using the skid (dry rocky mtn trails) to keep the right petals aligned. Also a little rear wheel hop to avoid rock hits. Its a blast and is fast fun. I usually ran 36x17 and just never rode trails that involved much climbing. I also rode to the trail heads so anything geared lower would be a rough commute.

    I use the same gearing on the fixed (32x18 on 26") as on all my freewheel SS bikes (32x20 on the 29ers).

    It is quite a bit of pedaling on the downhills sometimes, but we have no big hills around here so I can live with that. I like being able to climb the same climbs and getting the same behaviour from the bike when it comes to slow technical sections.

    Considering 1 tooth less when converting the 29er though, however that means shortening the chain which has its downsides.

    Personally, I used 32x16 even on marathon-distance races. I was pretty worn out after 62 miles at the Miles of DisComfort, but that had at least as much to do with the plethora of rocks!

    a hipster mtb???
    well, i did it,,,

    threw some 40c cross tires on my deep v's (was a bit amazed they actually fit), swapped to bigger cog & been riding my fg on some light duty-trails.

    i run big gear inches on the pavement & i don't want to change the chainring so i haven't been able let loose on the trails or really climb anything but guess what? it does work!

    unfortunately, i couldn't find anyone to video me in action but here's a pic of my "hipster" bike set-up for off-road, i can call my 700c bike a 29er, can't i?

    Heres mine. Vassago Wetcat geometry is perfect for fixed riding. I ride this bike on everything Southern Utah has to offer. Had an excellent Gooseberry ride today. Gearing right now is 32x18 but I'm still searching for the sweet spot. And yes those are platforms.
  • 03-03-2011
    Mr.Bee
    Get some Burro straps for the platforms you'll be surprised how much control it gives you on the trails.

    Nah, I'm happy with my set up. Thanks.

    Atomic - So are you looking to gear up or down? I'm looking to do Gooseberry some time this year on my SS (not skilled enough for fixed).

    32x20 or 19 seems to work for most folks in our neck of the woods... If your SS'ing and not fixed :)
  • 03-04-2011

    Yeah what Dave said. When I started SS I rode 32x20 and after building some muscle up it worked pretty well for Goose and Little Creek.
  • 03-04-2011

    Cool, thanks. Looks like I'll stick with my current 33x20 gearing.
  • 03-04-2011

    34x20 on my 26er, so i bet i would be about 32-20 on a 9er
  • 03-04-2011
    Atomicbarber
    I tried 32x20 the first time I rode fixed and it was easy to climb but pretty spinny on the downs and I was hitting my pedals more. A few more gear inches has helped that a lot.

    I just installed tomicog on my Milwaukee 29er. Never had problems with 165mm cranks on my fixed road/track bikes but I'm a bit worried about cornering clearance using 175mm cranks on my fixed 29er. Are you using shorter crank arms when riding fixed compared to ss mtb?

    Nope - 180. Learn to hop the rear wheel when needed to place the crank arms where you want/need. You will get pedal strikes, but you can learn to minimize or avoid them mostly. A little body english to keep the bike more upright while cornering is a good skill to learn as well.
  • 03-25-2012

    Rear wheel hop is definitely a very useful trick to handle. Maybe I just need a couple of pedal strikes to find out the limits and to get a confidence with the longer cranks...

    I do. I'm running 165mm cranks. Sugino forgot the model with 110/74 BCD. It was a triple crankset with forged arms and cheap steel chainrings. I tossed the latter in the trash. I see the XD-600 is the only thing now available, but more expensive than what I paid.

    My SS has 180mm crankarms. I've tried running SS and even 1x8 with the 165mm arms and didn't care for them at all..

    i ride xc & on some easier singletrack on this baby & i am always concerned about pedalstrike so i run 165 arms.

    can i call it a 29er? has 700 rims but 120 rear spacing...

  • 03-29-2012

    Muddy Steamroller looks always nice! If I remember right Steamroller has a relatively low bb height for a fixed gear frame. One reason why I ended up to Milwaukee 29er was 60mm bb drop. That should give more pedal clearance.

    I currently ride SS 29er at 32x20 gearing in the Dallas area. Pretty flat trails. Gets spinny on the flats. Make most short climbs. Considering going fixed to give it a try. Leg muscle is down right now due to injury recovery. Should I be considering a 19t or even an 18t for fixed?
