Disc brake rig
« on: October 06, 2016, 08:10:21 AM »
Built up and had a few sessions with the new brakes. First impressions of them.. how are they not more popular. The feel and power are so awesome! Feathering them is smooth and making smaller adjustments easier.

Don't mind the brake hose.. ive shortened it since.

I've thought about this and concluded that disc brakes aren't a thing in bmx despite their obvious advantages because of one or more of these reasons:
1. We don't really use our brakes that much riding bmx.
2. When we do use them U brakes are good enough for the most part.
3. Price and simplicity. U brakes are cheap and easy to set up and adjust.
4. Crashing. The prospect of having the rotor cut your leg in a crash. The roots could be prone to damage especially riding street.
5. Looks. People want their bike to look good and disc brakes just aren't very pretty. This is subjective or course.


That's a sweet bike you've got there. What pedals are those?

Nice work.

I don't know if I'd run a disc just because I like pegs too much, but for pegless riders it makes sense.

Has anyone seen where Clint Reynolds was playing around with a baby disc for bmx?  It was a much smaller size and looked pretty good.

Thanks guys!

Yeah I'm 100% trails ..definitely not peg friendly haha! Anyway I use and love having dialed brakes. Nothing against rim brakes.. the dust at my trails made my brakes suck pretty quick.

Looks are something I tried to smooth out. The caliper is tucked into the frame and mounted as low as possible. Normally it would sit on top of the seat stays.. witch is kinda ugly. Also I think they are easier to setup than U brakes. They come Pre-bled so you just center the caliper and your off.

Clints setup was cool! A 100mm rotor is a great idea.. I think a smaller caliper too would really help clean things up.

The pedals are Premiums..

What type of caliper have you gone with? A sleek little flat mount one, like the new road bike ones would look sweet on a BMX, post mount and ISO are both a bit bulky.

What rear hub are you using?

Yeah I looked into flat mount.. it's the right idea. It's compact but, very tall.. especially in the top right area. The rear triangle on a BMX frame is so tight, it was hard to fit. Did some cad drawings of that and ISO mount and the ISO I thought looked cleaner.. I went with shamano XT lever and caliper. Mostly picked because the lever is 1 or 2 finger and feels/looks closer to a BMX one.

The hub is a Profile elite 110mm 14mm axle.

stoked on this, need more info!

I have used TRP Spyres, Avid BB7, Avid BB5, and now Shimano SLX brakes on mountain and CX-type bikes and worked on tons of brakes over the years. Shimano all the way! Hope hydros are nice too. I think you could make this work with a 140mm rotor to keep it compact. no need for a bigger rotor than that on a BMX bike.
