It wasn’t all that long ago that both inner tubes and rim brakes were givens in the design of a new wheelset. Well, decades of established bicycle wheel technology get sidestepped with the new Stan’s NoTubes Alpha 400 Comp Disc Wheelset, and indeed, it is to the great benefit of the rider.
Stan’s, being a forerunner in tubeless rim development, created the Alpha 400 rim by simply further reinforcing its road-ready Alpha 340 rim. The 340 was already strong enough for cyclocross and gravel road riding, but the 400 kicks it up a notch by adding a third internal channel arch. Happily for us, the weight penalty is minimal: the Alpha 340 Disc rim is only 25 grams lighter. The disc-brake-specific version of the 400 rim still uses the 340’s Bead Socket Technology in its sidewall construction, allowing for wider sidewalls that grant the tire greater volume while reducing rolling resistance.
The disc-specific wheelset is built around Stan’s proven 3.30RD hub system, ready for the installation of 6-bolt brake rotors and laced to the rims with double-butted black DT Swiss Super Comp spokes. Despite being developed initially for duty on mountain bikes, the 3.30RD hubs are still quite light, at 167 grams for the front hub and 269 grams for the rear. Three pawls within a 30-tooth ratchet ring equate to a 12-degree engagement system, all tested to rigorous durability and longevity standards. Additionally, both front and rear hubs are convertible to any of today’s alternative axle and spacing configurations with separately available end cap packages, so your Alpha 400 Comp Disc wheelset easily hops from bike to bike. Out of the box, this wheelset is ready for standard quick-release dropouts (100mm front, 135mm rear).
Stan’s Notubes Alpha 400 Comp Disc Wheelset comes with black rims, hubs, and spokes, and is only available with a Shimano/SRAM freehub, compatible with up to 11 speeds. Both front and rear wheels have 32-hole black rims, and the set weighs roughly 1565 grams.
