Conceived at the junction of road feel, handling, aerodynamics and light weight, the Rail is the first clincher wheelset optimized for every part of the course. An 18mm inside width (25mm at the brake track) translates into the same tubular-like ride found in our vaunted FSW alloy wheels. Its aerodynamic shape is pure rocket science, relying on NACA airfoils designed originally for aircraft wings.
At 52mm the Rail is deep enough for remarkable aero performance, while remaining a practical choice for windy days and hilly rides.
A prototype of the Rail tested at the A2 wind tunnel in North Carolina was found to be faster at all Angles of Attack (AOA) than November's previous 38mm, 50mm, 58mm and 85mm wheelsets. Instead of benchmarking against a 32H box rim, we measured the Rail against the Zipp 404 Firecrest clincher. Despite being 6mm shallower than the Zipp, the Rail prototype gave up only 2 seconds over a 40K TT and performed better than the Zipp at low AOAs (below 7.5 degrees) more common at the high speeds experienced in sprinting, attacks and descents.
BRAKING AND HEAT MANAGEMENT:
The Rail is the safest and most dependable carbon wheelset November has ever introduced, and is constructed with new high Tg resins, capable of withstanding up to 350 degrees farenheit without warping, delamination or other damage. The Rail comes standard with industry-leading SwissStop Black Prince brake pads made from a proprietary compound that is proven to reduce heat buildup during braking by 35%. The pads vastly improve braking performance over many OEM pads, with modulation and stopping power comparable to high quality pads on alloy wheels. We can't change physics, so carbon still dissipates heat more slowly than alloy, requiring mindfulness to tube blowouts in extreme conditions. But significant upgrades to the resins and pad compounds means braking with the Rail inspires the same confidence as your favorite alloys.

Rail 52 Reviews:
CyclingTips blog: "transformed (the bike) into a racing machine that was immediately more responsive to my efforts..."
road.cc: "They feel stable even in strong crosswinds and in blustery conditions when some wheels of a similar depth can really throw off the handling and force you to correct your steering constantly."
AverageCyclist.com: "While putting in a big effort on a flat, I could feel myself pushing a bigger ring with more ease than normal. Though I will admit I did have a bit of a cross/tailwind and some motivation to really see what I could do, I was able to successfully set a PR by nearly 60 seconds on a 2 mile course."
