Anyone running a fixed rear with a disc brake on the rear?

If so, what hub did you use and were there any problems?

as far as i know, there are no disc compatable fixed hubs on the market, though paul/phil might make you one for $$$. I've run a suicide setup w/bb lockring on a singlespeed disc hub without problems, except for spinning my fool head off down hills at 42/19.

This would create an awkward set up. you'd need to have an eccentric BB or sliding vertical dropouts. Even then, on a fixed, most people run a front brake only.

Not really that awkward with so many companies (kona, nicolai, etc) building frames with sliding drop outs or eccentric BBs.

If I had the option of back pedal braking then I'd consider running one brake.

no worse then any other disc + ss setup.

Also many mtbers run fixed with a rear brake.

well as much as there can be many considering how rare fixed mtb is.

ok thanks - I found https://www.levelcomponents.com/tech.html via BTI's home page. Level comp. make a bolt on cog flip flop hub but they use their own 3 bolt system not the 6 bolt SI system.

If anyone knows of any other options please let me know - thanks in advance.

+1 on the first point

care to elaborate (comapny names please) on the second point

+1 on the last point but It'll be for road use only.

Every time you would install your rear wheel you would most likely have to realign your rear caliper. could make a rear flat change a huge PITA.

Sorry if I got your hopes up but all the FG mtbers I have seen were using v's.

I suggest you get bianchi roger and just loctite/rotafix a cog onto it.

Level looks like they have one in the works but who knows when it will be avalable.

Thanks - it's a long term thing anyway - at this stage still trying to figure out if I can without spending obscene amounts.

Didn't spot that from Level - Doh!

The Bianchi Roger uses a SS cassette hub, so you'd need a new rear wheel.

Phil makes a fixed disc hub. The only one i know of in production
It only comes in 135mm spacing and costs in the range of ~$300.

there is a company, however that produces a thread-on disc adaptor for flip flop hubs. Atomlab.
it threads onto the freewheel side of a fixed-free hub and converts it into a 6-bolt flange ready to accept a rotor.

awesome - thanks

Edit: - Phil Wood Kiss Off disc/fixed hubs in either bolt on or QR
- could only find Atom Lab disc adapter mentioned once in MTBR reviews - no-one seems to sell it anymore

why cant you backpedal to brake? are you going to be running powercranks on this bike too?

Probably - when I can afford them again :/

use a normal cassette wheel with a surly fixxer...

Why do you want a disc on the rear of your fixed? It's overkill. In fact, any rear brake is pretty unnecessary. If you really want to do it, use a disc single speed hub and a BB lock ring with loc-tite.

Some people like non-ghetto solutions. Luckily someone's already provided the only answer for him.

Some people like multiple solutions. Maybe you missed this:

yes, trying to save money, and no, not truly ghetto

It does look as though the expense will be the hub - everything else (frame, powercranks, bits to make it go) I can probably e-bay.

Either way, given the finances, I won't see a rideable result before next summer.

Question: if you are using the powercranks and it won't allow you to back pedal, why do you want to run it fixed? Why not just run a freewheel? Trying to wrap my head around the powercrank/fixed combo.

no good reason - hope that helps.

I don't really know apart from hearing about other powercrank/fixie combos that work really well together (everyone from commuters to sponsored ultra distance riders). Probably goes hand in hand with "why doesn't everyone ride internally geared chainless recumbents?"

I think that there's someone out there making a dual front disc hub for down hill racing, possibly do that with a bolt on cog. but I have no clue as to what that would do to chain alignment, considering a front hub is 100mm. hmm, maybe a front dual disc hub is wider...

eccentric BB eliminates this.

fixed gear + power cranks
