Furry's fat and long bikes

Would it not be possible to take the brakes from your belt drive single speed onto the fatbike until you got the right one?

Thats set up for 140mm rear/ 160mm front discs. The fatty has 160mm rear, and a beefy 203mm front.

I can mount the rear direct, as my sliders are post mount. I would need to steel the 203mm adaptor from my cargo bike to fit the front. With my selection of discs and adaptors I could sort the cargo bike at a different size.

Its doable.

The race is on. Just waiting on final prices for parts for mine.

I'm putting my headset in the freezer as soon as I get home. Then I predict a long drawn out struggle to get everything to turn.
