Clearance for a grand experiment

I ride fixie, and i ride with a front brake.

I also love doing tricks, but the brake cable ends up being a barrier in performing barspins and whatnot.

This is my idea. Can you put a BMX detangler/gyro on a road bike?

I was thinking this the other day when I was looking through the Dan's Comp catalogue...just for an experiment.

If you're using a front brake only, you don't need a detangler. You just need a hollow star nut and a brake that pulls from the bottom. Look at freestyle bmx setups.

Will your bike even have clearance for barspins with a front brake on it? On, a lot of frames/forks, I'm pretty sure the brake will hit the bottom of the downtube, even in your wheel will clear the frame.

You could also really complicate things and use a disc brake in the front with a hollow star nut.

Wouldn't the cable housing eventually twist too much?

yes^.
And yes, in most cases the front brake itself will strike the frame.
I think disc + gyro is the only way.
Yet another step toward some track/road riders becoming bmx wannabees.....
(not that i'm against it, it just seems funny to me)

no. cable goes thru the hollow star nut, and obviously thru the fork tube. the front brake assembly is independent of the frame entirely. as long as the handlebars are secuured to the fork there is no moving assembly within the front fork/stem/bar combo aside from headset bearings

and a gyro WILL NOT WORK for a front brake. the gyro has the lower section fixed to the frame. from there where can the cable go to the front brake and still allow free rotation? its a parallel situation to if you just ziptied your front brake cable to your headtube.

Disk brake + hollow star nut.

Profit.

*Disclaimer* - The generally more relaxed geometry of most disc forks means that the wheel may not be able to clear the frame regardless.

has been discussed before. assuming your front wheel does not have any downtube clearance issues, use a hollow starnut, with an aero brake (the kind that will fit behind the fork. braking force is reduced compared to a traditional setup, but you can still do barspinz. a friend has this setup around town because if a cop wants to be a dick, he can give you a $120 ticket for not having a brake and it can also go on your driving record as a moving violation. and he loves his barspinz.

Disk requires disk fork. For retrofitting an existing fork, check out various drum brakes.
