Two new wheelsets from Zipp, the 30 Course tubeless-ready and tubular variants, bring more options for disc-brake road and cyclocross riders. Zipp sees these wheels as an excellent multi-use speed weapon designed for everything from road adventures to full-on cyclocross racing. Being the first tubeless compatible wheelset from Zipp, they were developed around a wide 21mm internal width with a true shelf to hold tire beads at the lower tubeless tire pressures we can expect on the road, gravel, and cross courses. Both aluminum tubeless and tubular rims use a similar 25mm wide overall profile that is 26mm deep, combining some of the aero benefits and predictability in crosswinds of their top-level wheels at a lower price point and without the compromise of including a parallel braking surface that shapes the standard 30 wheels.

Zipp sees these as a new benchmark for a durable, high-performance aluminum disc-brake wheelset, and it looks like they may signal more focus on disc-brakes combined with the aero background Zipp is known for. The wider rim profile, which Zipp has been pushing for years in the carbon offerings, bring the ability for higher tire air volume, spreading a standard tire casing to widen the tire contact patch with the road. As a result the wheels should lean towards better cornering grip and increased comfort, especially on rougher road, gravel, and dirt rides and events (like those the pros will be suffering through on this weekend’s Paris-Roubaix.)
Both wheel variants use the versatile new 77/177D hubs developed for the higher-end 202 and 303 disc-brake wheels, with 10/11-speed Shimano or Campy compatible cassette bodies standard. A SRAM XD cassette/driver body is also available separately. The hubs are thru-axle compatible, and wheelsets come with tool-free end caps to swap for the most common axles: front, 12x100mm & 15x100mm; and rear, 12x135mm & 12x142mm. Both wheelsets are built up front and rear with 24 Sapim CX-Ray spokes and secure-lock nipples. And the tubeless-ready wheels ship with rim tape and tubeless valves.
Both wheelsets will retail for $1,000/€1,045/£800. We were told availability will be from June 2015, but Zipp’s site promises clinchers in May and tubulars not until July (but in plenty of time to glue up cross tires!)
