2012 Reynolds Assault CX disc brake cyclocross wheel with 135mm rear spacing
Reynold’s new Assault CX is their first cyclocross-specific wheelset (at least in a while).

The rim is their Assault road rim, but it’s laced up 2-Cross 24 count front and rear for a little sturdier build. Rim depth is 46mm and it has a 20.8mm inside width. Because it’s the same rim, it can be run with rim brakes, too, letting you upgrade your wheels now without worrying about them being obsolete the next time you get a new frame.

Asked if the clinchers could be run tubeless, they quickly said “no”, then added that they know of people running them tubeless, but because they haven’t personally tested it, they can’t officially recommend it. Of course you’d have to find a tubeless valve stem long enough to extend through the rim.

Weights are 1496g for the tubulars and 1716g for the clincher. 135mm rear spacing, 9mm QR only. The front hub pictured here is simply missing the end caps. MSRP is $1,750 for the pair for both rim types.

Reynolds has been on a roll (pun intended) lately, introducing the $1000 R2 carbon rimmed wheels followed by this and some new mountain bike wheels we’ll post separately.

“Because it’s the same rim, it can be run with rim brakes, too, letting you upgrade your wheels now without worrying about them being obsolete the next time you get a new frame.”

Um, sorta. They’re spaced at 135mm. Unless your frame is steel then you can’t (or shouldn’t) re-space it. And if you’re getting a frame that is 135mm then its most likely disc ready and you’re probably going to go that route. Personally, if you’re going to spend that kind of coin on wheels, I’d wait another year until they make a disc specific rim that should be lighter and stronger.

They make these really cool valve extenders that move the actual valve to the outside of the rim. You don’t need the worlds longest tubeless valve with that

@bk – the extender needs to have thread on it for the locknut which holds a tubeless valve in place. Most extenders don’t have this thread.

Who is the genius that decided to leave end caps for thru-axles on both wheels?

Kind of dumb in my opinion to not have disc specific rims for disc wheels, and make them clinchers to boot. If someone is going to buy the 135 spacing rear disc frame and shell out for upgraded carbon wheels they have already committed to discs, give em a disc specific rim to reduce the inertia of their wheels. (oh and also make the tubular version of disc specific rims because a racer that wants a disc cross bike isn’t going to buy clinchers). For general use and training it is more likely that people will want an alloy clincher setup, and for racing go with either alloy or carbon tubulars.
