Reynolds has been on a steady march toward a complete line of disc brake road wheels, starting with the Assault SLG clincher disc and their alloy Stratus Pro models.

Now, the Assault SLG Disc tubular follows the standard rim-brake set announced at Eurobike. This is still a 2014 model, look for it in late May/early June.  If you wanna see what’s coming for next year, roll on…


For 2015, the 46 Aero Clincher will get a disc specific rim and build. These are early prototypes, so that decal will be replaced with their inkjet graphics for a cleaner look and lighter weights. Specs aren’t disclosed, but the rim dimensions will presumably be the same as the standard 46 Aero clinchers. Details are sparse about what changes are made to the rims to make them disc specific, but we’ve asked. Updates if we get any. (UPDATE: We got updates!)

UPDATE: For the carbon disc rims, material was moved from the brake track toward the spoke bed. With all disc brake wheels, they’re getting 24/24 2-cross lacing front and rear, so they wanted to reinforce the spoke holes and nipple beds a bit more. Across the board, Reynolds’ rep says there’s an average of just 5g weight savings per rim. For now they’re using a 6-bolt rotor mounting standard, but CenterLock hubs could be an option in the not too distant future.


The Attack SLG will also get a disc brake ready clincher version for 2015. Both of these will be officially unveiled around Eurobike.



  1. six bolt rotors are junk for road applications, heat warping and minor distortions are a minor issue with the lever pull on a mtn bike, but its a fatal flaw with road levers.

  2. So you spend the extra money on deep carbon rims to reduce drag and then you bolt a whopping big disc on it to increase drag. Can wait to see the marketing bullsh*t they come up with to sell this stuff.

  3. 1. Person wants disc brakes.
    2. Person also wants to reduce drag.
    3. Person realizes that aero wheel with disc is more aero than non-aero wheel with disc.

    It’s pretty simple, really.

  4. Enve saved a bunch of weight going to a disc-only layup for their 3.4 disc rims. I can’t think that their engineers are really that much better than Reynolds’, so were their standard 3.4 rims over built, or is Reynolds missing an opportunity here?

  5. At the very least, I’d love to see Reynolds completely eschew internal nipples. Two of the wheels pictured above seem to be moving in the right direction. Ever had to remove a tubular tire from a Reynolds wheel, just to true it? Total PITA.

  6. been using center lock since shimano introduced it for mtb. never had an issue, super simple, and makes cleaning/removing the rotor quick and easy. Design centers automatically, no need for lock tight. less screws, bolts, or washers is always better.

    i am surprised c lock rotor design has taken as long as it has to start to become more popular.
    hed, dt, and white industries (to name a few) gets it. (yah a licensing fee, but still)

  7. my opinion, as far as the inkjet graphics is that since it is basically permanent, reynolds will lose more sales than gain sales when it comes to their decision of graphic application.

What do you think?
