Was that or one like it at NAHBS in Portland? Think that's where I saw it.

looks like it might hurt . . .

I don't want a brake that depends on a chain . . .

Thinking the same thing, and that disc might make a good slicer.

No no. And no

Agree. If you want brakes on your fixed, put them on the wheels. This seems like bike jewelry. Pretty execution though.

I think it's pretty neat. I would want a backup front brake along with it, and I'd be a little afraid of burning myself on it.

All I see is ouch (cool looking ouch)

Well done and cool in my opinion but I would use a smaller rotor.

[Mark McM]

Due to the gear ratio, the torque at the wheel is ratiometrically reduced (speed is ratiometrically increased). This means that more braking torque at the crank is required for the same stopping force. In other words, this system has net leverage decrease, and will likely have less stopping force than a rim brake for a given hand force. (the fact that the cranks are in direct line of water spray from the front wheel probably doesn't help, either.)

I believe Sycip did this as a fun project with White Industries, it seems as a joke for getting pulled over for not having a brake.

Sycip had this on display in their booth at NAHBS 2008.

Novel.

Just because you can doesn't mean you should.

but...... discs located on hubs. i ride fixed gear bikes on the road, and when you are going downhill, spinning quickly and moving fast you have a tremendous amount of force making slowing down and stopping difficult.

because of this, i plan on switching to disc brakes on my next custom fixed gear bicycle. having lots of stopping power and excellent modulation make disc brakes an excellent pairing.

it's hard to give up the beauty of riding campagnolo super records on a steel bicycle, but i'm sure they make or will be making good looking polished alloy disc brake hardware to match my steel retro ride.

right now, any true fixie without any brakes is dependent on the chain to slow down anyway...note that a track chain is pretty solid but a disc brake will put more force on the chain...

Hot rotor on my leg? No thanks!
(I'm aware they are not serious in taking this to the market or anything, just for fun. Cool execution!)
