Over the last six years I’ve become a convert/proselytizer first for tubeless, and then tubeless on wide rims. The ride is smooth, cornering is excellent, and I haven’t flatted once in those six years. Every time I see someone changing a flat by the roadside it’s all I can do to hold my tongue. The only drawback was the lack of an affordable wheelset for this setup.
A-a-a-and this is where Revolution Wheelworks’ Rev-20s comes in. Built with Velocity’s A23 rim and Sapim CX-Rays, the Rev-20s come in at 1438g (1430 claimed) and $690, which makes it lighter and cheaper than most of the big name offerings. At 160 pounds I’m right at the recommended weight limit for the 20/24 spoke build. I chose them instead of the 24/28 to see if I could wreck them.
RWW make no secret of the fact that they source existing parts for their wheels. What they offer are well spec’d wheels, sane pricing, and most of all, excellent build quality. My test wheels were indeed perfectly true and evenly tensioned. I taped them up with Stan’s tape and brought them to Mark Purdy at iFixByx to mount the tires.
Mark and I have noticed that tubeless setups can really cause spoke tension to plummet, so we took measurements before and after airing up the tires. The rear non drive side went from 100Kgf down to 70, and the front went from 83 to 55. I brought the tension back up with the tires mounted and the wheels have stayed true since. If you’re planning on going tubeless RWW will build the wheel with extra tension to save you this step (but I’d still check them after inflating). They’ll also sell you a $15 tubeless kit which includes the rim strip and valves.
So…they’re reasonably priced and well built. Tires transition smoothly into the 23mm rims for a smooth ride that rails corners. They’ve proven durable even though I’m right at the edge of their weight limit – they’re good as new after 1,600 filthy winter miles but for a little roughness on the rear bearings. All I have to add is that these are the lowest profile rims I’ve ridden in a while, and I’d forgotten what it’s like to be invisible to crosswinds. It’s very nice to descend at speed and not be freaked out by a gust of wind or a passing semi.
