The great all-rounder - Zipp's 30 Course Rim Brake Clincher Wheel
The Zipp 30 Course Rim Brake Clincher rear wheel rewrites Zipp’s own stringent rules for performance, durability and versatility in an aluminum wheel.
The 30 Course’s wide rim profile and new hubset are engineered to deliver speed, stability and comfort over any surface road bikes are tackling these days… smooth (and rough) pavement, gravel and dirt. This is Zipp’s first rim brake, tubeless-ready wheel, providing the ability to run lower tire pressures without the risk of pinch flats.
With an external rim width of 25mm and internal width of 21mm, the 30 Course’s rim shape incorporates design innovations from the Zipp 202 Firecrest Carbon Clincher profile, resulting in low aerodynamic drag as well as greater stability and predictability in crosswinds.
The wider rim platform allows for increased air volume, which spreads the tire casing. This helps increase the contact patch with the ground. The result is improved cornering grip and increased comfort.
The 30 Course also features the new 77/177 hubset, the same now being used in Zipp’s pro-proven 202 Tubular and Firecrest rim-brake wheelsets; it's a new robust hub platform with distinctive graphics. It boasts optimized flange geometry and spoke hole attachment pattern with Sapim CX Ray spokes and a 17mm axle.
For those looking for a wider gear range, or tackling especially extreme terrain, an XD driver body for 177 is sold separately and easily installed to allow for more cassette options including a 10-42. The hubset is designed to swap driver bodies without re-dishing the wheel.
The 30 Course Rim-brake wheelset also includes newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing. When closed, the new lever contours neatly with the frame.
