Are these too flimsy for a full susser that while not freeride will get to jump off something (albeit small) every now and again?

They are Sapim's strongest spoke so I doubt the odd huck would cause issues.

As above, they're recommended for downhill use.

Having used them for several sets of wheels I wouldn't bother any more I must admit, they're a bugger to build with and making truing the wheels difficult for no real advantage IMO.

As the negatives are being listed - they cost a frikkin' fortune.

Well yes, that is true, although still less than DT Aerolites.

because each spoke is x-rayed for faults. They are mega strong, light and aerodyanmic. Probably only worth it for racing though (DH, XC, road...)

They are a pain to build (kills your hands tensioning them, getting them in spoke holes), cost a fortune and being aero has very little benefit on a MTB. However they are the strongest spokes available bar none. I had a set of road wheels built with them after busting numerous wheels road racing. Raced more than 5000 miles on them, plus training. They are still hanging up in my garage - just ended up wearing the rims thin.

Why worth it for XC? Revolutions are about the same weight, (I forget if there's a standard butted spoke the CX-Ray is 'based on'), much cheaper, plenty tough enough.

There's sod all aero advantage on an MTB. I certianly wouldn't turn down a set of wheels because they had them, but I wouldn't bother buying them.

The strength issue I can sort of see for DH, but it's tenuous!

Do DH riders not care about aerodynamics? They're going fast enough for it to count

Really? Isn't it just fatigue life that's high? Strength is surely about guage (and aren't they flexy like revs?)

I said it was tenuous, how many casual DHers wear skin suits and take the peaks off their helmets? That'll make a hell of a lot more difference than some slightly bladed spokes.

They have the highest fatigue strength yep, but isn't that usually why spokes fail? They are as flexy as Revs though!

'tis true. I just wondered if any did.

The top World Cup boys certainly do, did you not see the thing about Steve Peat's bike for the worlds, stripped paint off wheels and what not.
