We can all stand to be better climbers, and none of us are going to get there with 50mm deep wheels. Because in a world of gaunt, Italian mountain goats, not only do low profile wheels reign supreme, but Shimano is the wheel of choice.Shimano's WH-RS20-A Clincher Wheels are what you're looking for if you want to have lungs at elevation, or simply want great wheels. Utilizing nearly 100 years of innovative experience and a design that rivals wheels three times the price, the WH-RS20-A is a must have for the mountains.

Shimano's WH-RS20-A Clincher Wheels benefits directly from the wheel technology developed for Shimano's top-tier Dura-Ace. The most notable is the incorporation of Shimano's angular contact bearings. This may seem like a small feat, but it makes a world of lateral and torsional rigidity come to life under your legs. The bearings' shape allows them to be pushed as far outboard as possible. This makes the hub a wider platform for the spokes to stand on, and thus creates a stiffer wheel with higher spoke tension—think about the difference between someone pushing you with your feet together, and then again with your feet shoulder-width apart. While this system adds weight at the hub, it takes it away from the rim. Centering the weight at the hub amounts to a lower rotational weight, and that means more efficiency, less effort, and faster accelerations. Throw in a slight aerodynamic advantage with the RS20-A's 20mm deep aluminum rims and a 16/20 stainless steel spoke count, and you have a KOM killer of a wheels.

The Shimano WH-RS20-A Clincher Wheels are available in the color White, and includes front and rear quick-release skewers. The freehub is compatible with 8-, 9-, and 10-speed cassettes, and is available in two options to accommodate Campagnolo and Shimano/SRAM cassette bodies.

Do these wheel sets, or for that matter ,...

Do these wheel sets, or for that matter , other wheel sets from other manufacters include the weight of the skewers in (grams) when shopping on the web.

Responded on

No, not usually. The weights are generally the naked wheel; no skewer, rim strip, tire, or tube.
