Reba world cup 29er, anyone? NCJ01?

mattomoto listed JHK's fork for nats as "RS Reba 29 stock w/poplock"

Real world question - wtf cares? How much could a different crown save in weight? Do you want that on the already longer lever that is a 29er fork?

Pot, this is kettle..........you are black.

According to the Rock Shox website, the weight difference is 50g.
Am I going to drop an extra $250 for the World Cup? Nope. If I was sponsored by Rock Shox, would I switch them at a nominal cost (most likely free) for an xc race? Hell yeah, why not? Its not like its going to break over the course of a race. I'd roll no-tubes and Stan's aluminum rotors and ti-colts all over the place, too. 50g is 50g for a racer, yo.
So... the question remains. Anyone done it?

Yeah, I've done it. I haven't yet gotten my new frame, though, so I haven't had a chance to ride it.
As odd as it may seem, I primarily went for the carbon as a strength issue- with all this talk of creaky Reba crowns and no failures that I've ever heard of from RS carbon crowns, it seems like a good idea to me.
The weight difference is a joke, but it does look super cool.

Let me see if I can help with this-

I wanted to get this done for JHK's 29er earlier in the year. RS said it could not be done because of the differences in lengths and where the bushings sit in the legs. If you cut the travel down to say 60mms of travel, maybe, but whats the use?

Anyway, RS did some testing on a couple of carbon 29er forks they put together and found they did not stand up to their testing. Too much leverage on a 29er fork. We were close, but safety is better than 50g's

As I found out, the Reba 26 forks are stiffer with the alum. crown/steerer than the WC with the carbon crown/steerer. Interestingly enough, in the SID line- the WC carbon crown/steerer is stiffer than the alum. version.

Where the bushings sit in the legs? The upper assemblies are exactly the same, 26er vs 29er.

I had hoped to do this (carbon crown/steerer on the Reba 29) to shave some grams from my SO's Leviathan. I contacted an engineer at RS, and he said that I shouldn't even consider it, even though she's an unaggressive 115lbs. Echoing what was written above, he said they tested a few and were not satisfied with the results, even for limited use by lighter riders.
