Zipp 303

The 303 is available in tubular or clincher versions. The tubular version is lighter, and features Zipp's Silica Ceramic braking surface, whilst the clincher version has an aluminium braking surface and the convenience of clincher tyres. Designed for severe racing conditions dominated by steep climbs, wicked winds, and the need for immediate acceleration, the technology-packed 303 significantly diminishes muscular road fatigue through the use of a vertically compliant carbon element, whilst offering lateral stiffness more than double that of a traditional rim.

Price: Ł840 (pair: Ł395/front, Ł450/rear)

303 Tubular:

The Zipp 280 rim weighs a mere 285g, which combined with the American Classic hubs, makes for one of the lightest wheelsets available. The rim features a 38mm deep shape, and is typically built with 18 radial spokes in the front and 24 laced two cross in the rear. Each set is custom built to suit the rider; various spoking patterns are available.

Example build 1:			Example build 2:
24 spoke radial front			18 spoke radial front
24 spoke 2 cross rear			24 spoke 2 cross rear
Front wheel = 470g			Front wheel = 418g
Rear wheel = 614g			Rear wheel = 592g
Pair = 1084g			Pair = 1010g

303 Clincher:

The Zipp 415 rim weighs in at 544g, with a depth of 40mm. The structural carbon rim is melded with Zipp's proprietary sub 200g welded aluminium alloy rim to offer a unique combination of clincher versatility and the advantages of high performance carbon rims. Again, typically built in a 18/24 spoke combination, but made to order to suit the rider.
