My DE Wheels arrived today and I must say I like them a lot.
They also fit on the rear with no need to worry about enough thread on the axle/nut and also fit on the RB6 front axles with no mods or going the RB5 axle/hex.

Plus this thread needs a pic

Could you report back on durability after a couple races?

I have yet to break a carbon part and I'm running everything except the front shock tower. I'm really impressed with these parts.

Going by the crude way I could measure it (don’t really have the right things to measure it 100%) I would say with they are the same offset.
Or at least within hundreds of a mm

Yeah, I like them too. Just got some last week and decided to use them for my carpet tyres. I used them on an indoor carpet track last week; broke some other stuff but the wheels held up fine. Paint job a pale imitation of one posted somewhere earlier in this thread. They are slightly heavier than the AKA Hexlites though.

Those are carpet/turf tires. They are smaller profile than dirt tires.
