Zonda Carbon is Campagnolo's most direct way into its carbon wheels, made for riders whose routes swing between smooth tarmac, broken roads and gravel. A 50 mm carbon rim gives aero efficiency at cruising speed, and the 25 mm hooked internal width suits modern tubeless tyres from 29 mm.

Highlights

• 50 mm carbon rims, C-LUX finish
• 25 mm hooked internal (C25), tyres from 29 mm
• 2-Way Fit: clincher or tubeless, undrilled rim bed
• G3 spokes, 21 per wheel
• Cup-and-cone bearings
• Claimed 1,550 g the pair

Rims

The high-modulus unidirectional carbon rims are made in Europe with a mould-finished C-LUX surface. The rim bed is undrilled and hooked, 30 mm wide outside and 25 mm inside, for tyres from 29 mm up to 40 mm and beyond.

Hubs and spokes

Single-piece black aluminium hubs run on fully adjustable cup-and-cone steel bearings (15/28 mm front, 17/30 mm rear). Each wheel has 21 straight-pull, tapered round-section spokes (2/1.6/2 mm) in seven groups of three; the G3 pattern balances tension against drivetrain forces at the rear and disc brake forces at the front.

Options

Compatibility & fit

Disc brake with 12 mm aluminium thru-axles, 100 mm front and 142 mm rear. Choose the freehub body that matches your cassette. N3W takes Campagnolo cassettes that start with a 9 or 10-tooth sprocket (such as Ekar and Super Record Wireless) directly; cassettes that start with 11 or 12 teeth need Campagnolo's N3W adapter. Cassette fitting and tubeless set-up are separate workshop services at Tune Cycles.
