Got a weight for it? Looks sick.

Reminds me think of all the sweet 4x bikes you used to see when it was part of the World Cups. Watched the Pro Tour last weekend at Fort William and there were only a few guys on full on 4x setups and most of those were very much 'real world' specs. A lot of the riders were on trail or even enduro bikes and there were some pretty retro rigs on the go.
thanks, need to throw it on a scale

Pretty much all manufacturers stopped making 4x frames so there aren't many factory options for racers anymore

I am entertaining riding my DJ in the cruiser class at the BMX track. What gearing are people shooting for on flat tracks? 34t x 16 right now but that's my DJ/pump setup and comes out to 55.25 rollout... Was thinking 34x14 which jumps to 63.. Not sure if I am man enough for that. But I could be wrong, I have no reference since I have never raced BMX..

Galfer had at Andorra world cup a Prototype 246mm rotor on display that are 2,3mm in thickness.

What current forks allow a >220mm rotor? Fox and RS don't cover their use under warranty IIRC.

With that mount and how thin the rotor is it looks like there would be major flex

That's the double rotor tho. That won't fit in any other calipers.

Everything about this pic looks dodgy as f*ck...

I say props for doing it!! I would’ve added another arm in the rotor but still looks damn good!!

Would trust it more if the mounting points on the fork were spaced further apart and more inline with the two arms of the bracket, I realise it's due to the USD fork but it looks dodgy as f*ck to my pinkbike engineering degree.
