Reynolds Assault SLG Carbon Wheelset - Tubeless $1,499.00
Explore new roads.
The days of relegating road bikes to strictly smooth pavement surfaces are over, with riders and manufacturers proving that all-road adventuring is the next frontier in enjoying a well-rounded cycling lifestyle. As such, we need a wheelset like Reynolds' Assault SLG Carbon Tubeless Wheelset that can keep up with our more spontaneous ride route choices. Newly updated with stealthy waterslide graphics for an extra dose of style watts, the Assault's 41mm profile hits the sweet spot between low weight and aerodynamics, bringing Reynolds' renowned crosswind stability to nearly any all-road application.
Whether you're winding up for the rolling hills of a coastal road race, rocketing through Vegas' legendary sand pit, or packing up for a weekend of mountainous multi-surface adventuring, the Assault is up to the challenge. An all-new hubset builds on this wheelset's famed versatility with smooth, fast turns and even quicker engagement than its predecessor for a ride that rivals the responsiveness more often found in wheelsets at much higher price points.
Traditionalists among us will appreciate the ability to run the Assault as a tube-type clincher, and for those of us looking to ditch tubes, the rims' redesigned shelves and hooks hold a tubeless tire securely at low or high PSI. The lower rolling resistance and comfort of a tubeless ride is complemented by the Assault's wide rim, which lets tires sit with more volume in a way that Reynolds calls "modern" but we call less rolling resistance, better cornering, and a more comfortable ride.
The new Assault also sees an update to Reynolds Cryogenic Glass Transition (CTg) brake track technology, with a taller profile and reworked resin system that extends past the brake track and into the rim to provide exceptional heat dissipation, all but eliminating the risk of the rim deforming or failing under long, hard brake use. Each Assault wheelset also includes Reynolds' proprietary Cryo-Blue Power brake pads, which work with the CTg laminate to produce more consistent (read: safer) braking. Safety is also improved through Reynolds' PR3 construction method, which uses different carbon fiber, epoxy, and resin for each of five rim regions.
Last, but far from least, the Assault utilizes Reynolds' Enhanced Swirl Lip Generator (SLG) design. There's a heap of wind tunnel tech behind SLG, but in a nutshell Reynolds adds a small lip of carbon on each side of the rim near the spoke connection points. The lip streamlines airflow across the spokes to reduce drag, and this iteration of SLG comes with claims of a 35% improvement in aerodynamics over the smaller original design. Long story short, SLG just makes these wheels faster.

Fast wheels, great price
- Familiarity: I've used it several times
These are my first set of 'deep profile' carbon wheels and I am glad I finally upgraded. Once you get these wheels up to speed, they just keep rolling and rolling. Compared to my previous set of wheels, I can feel the crosswinds, but it was easily controllable.
I was hesitant to purchase these wheels because of other reviews which talked about the difficulty installing clincher tires, but I did not have any problems what so ever getting a set of GP4000 II tires on and seated. I haven't had to change a flat yet though... so fingers crossed.
Buy the tubular version instead
- Familiarity: I've used it once or twice and have initial impressions
I took over 3 hours to mount tires on these suckers (Vittoria Corsa CX) and had to prestretch the tires at the maximum 145 PSI on another wheel to get them on at all. Pumping them past 90 PSI for the first time yields a number of loud cracks, loud enough that I wore ear plugs. Once they're on, have fun taking them off. The bead is completely wedged into the wheel when the popping/cracking happens, so it is absolutely impossible to pull the tire bead back off the wheel. It is stuck on like a tubular tire, but worse. I don't know what the outer diameter of these wheels are but this is just nuts.
I have another set of tubeless wheels which takes longer to install tires on than regular clincher wheels, and it takes me no more than a minute with the same tires. I only bought clincher wheels because I wanted to be able to change my own flats during century distance rides, but I'm definitely bringing these into a shop if they ever flat... I really wish I had bought tubular wheels instead, because even 3 layers of glue isn't stuck on tighter than the tires on these suckers, and you can't fix a flat on the go anyways.
If you're still dead set on buying these, buy extra tire levers (you'll probably break some), extra tubes (regular thick type or they'll pinch, but you'll probably pinch thick ones too), stretch the tires on another wheel if they're new... and a steady supply of your alcoholic beverage of choice.
Great performance for a great price
These wheels are a little difficult to mount tires on, but, if you know the tricks, you can get them on no problem. Keep the tire beads in the center of the wheel, start opposite of the valve stem, finish so the valve stem is in the middle of the last section of the tire that needs to get over the rim, push the valve stem outward into the tire, then use a lever to finish the job.

These wheels are downright fun to ride. fast rolling, super stiff and shockingly quick and reliable braking power. Having ridden a number of carbon wheels in the past for races, I usually tried to use my brakes as little as possible (as one does in a race scenario, right?) but I always found that in my moments of need, all carbon wheels I had used in the past have had terrible braking power. Slow to bite and unreliable in wet conditions, I was at first nervous to invest in a carbon wheel upgrade. All doubts were put to rest on my first ride on these wheels. I was shocked at the extremely quick and efficient braking power and very little screeching noise upon braking. I am currently running these wheels with tubes on my road bikes but I love the ability to easily go tubeless and ride gravel/ cross on these bad boys. The wheels are lightweight, fast rolling and a very very smooth ride. These wheels have truly transformed my bike and riding experience. 41mm depth is easily manageable in crosswind and aerodynamic enough to race or every day training rides. I slapped an 11-25 Ultegra cassette on there and now I'm always stoked to ride up a big climb.
Extra side notes:
-Wheels come with QR, tubeless valves, tape and brake pads.
-Reynolds now has a lifetime warranty on 2017 model wheels and all wheels going forward.
-Warranty registration can be found here: http://www.reynoldscycling.com/support/register/
tires are Incredibly hard to mount on these wheels due to the tubeless design. If you are running tubes, be ready to have an uber or friend come pick you up if you get a flat because changing a flat and getting the tire back on the wheel is downright near impossible. This has been a HUGE issue for me. I've found once tires getting more worn down this becomes easier but still harder than it should be. I would recommend running these tubeless or with an extremely supple tire.
