Is it possible to put a gyro onto a fixie so that the bike will have a front brake and the ability to do barspins on? Thanks.
P.S. My head tube is 8.25" tall/long and 1" inside diameter. Takes a threaded fork. Thanks!
No, that's not how a gyro works. A gyro is designed for the rear wheel and with some sort of on-frame support for the cable housing.
Since you're using a threaded headset, and not a threadless bmx headset, you won't be able to have a front brake and do barspins. The topcap on a BMX headset is oversized and the bolt for that headset has a hole in the center through which you send your brake cable.
Also, good luck finding a straight-legged, threaded 1" fork with brake posts. And a fork with brakes (whether center-pull, or linear-pull, or even U-brake) won't be able to do barspins on a track, touring or road geometry bike.
in short... no.
i have seen a front brake cable routed though the steerertube. then you can spin to win!
- the revolution will not be motorized -
I thought this was about greek food!
it's almost lunch time so i immediately thought food
i could go for some falafel right about now
I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

If you've got a threadless headset drilling a hole in the top cap and routing the cable through there also works. Pretty similar to the pics above, but with no special hardware required.

Probably also a 1 1/8 headset too. Wasn't the Milwaukee Cycles trick by also being sold with the option of a headset like the one pictured above?
You need the potts mod topcap, bolt and starnut for 1 1/8" period. You need an 80's ish BMX stem or potts mod bolt/wedge (unless your wedge is the same angle and thread) for 1" period. Any other advice is horse puckey. Any of which should be available through Ebay or Danscomp.com or albes.com.
A gyro CAN be used for rear brakes with minor modification.
To use either potts mod setup you will need to invert the cable attatchment points on the arms of your brake.
A 650c wheel may be needed to clear the frame...it will take some trial and error work but it isn't hard.
