Reynold's solitary alloy rim, the Stratus Pro, was updated last year to include a disc brake specific model, much to the delight of mudslinging, gravel crushing, disc braking cyclists across the world. Similar to the rim brake option, the Stratus Pro Disc Brake Road Clincher Wheelset features a lightweight, narrow, tubeless ready profile laced to Reynolds' race hubs, resulting in a wheelset that's durable enough to handle daily training on almost any surface and lightweight and responsive enough to throw down in a race. Reynolds builds the Stratus Pros with 28mm deep aluminum rims, which split the difference between low rotational weight for fast spin up off the line and out of corners and deeper rims' aerodynamic advantage. Unlike a full carbon wheel, which may feel a bit stiff for everyday training, aluminum provides a damping interface between the rough road and your body to smooth out energy sapping road vibrations. Nonetheless, the Stratus Pros wind up fast and hold speed well on flats and descents, aided by the smooth rolling efficiency of Reynolds' racing hubset. 24 radially laced front spokes and 24 rear spokes laced in a two cross driveradial non drive pattern hold everything together, with the spoke nipples on the exterior of the rims for easy service and maintenance. One of the more noticeable characteristics of the Stratus Pros is that they're tubeless ready, which opens up a whole new world of tire pressure options and flat tire avoidance. With their low profile rim hooks, these rims pair with a tubeless ready tire and your favorite sealant to create an airtight, puncture resistant seal. For the traditionalists among us, the Stratus Pro rims will also work perfectly well with a standard tube set up.
