Where gravel meets road: the Zonda GT is an aluminium disc brake wheelset with a 23 mm internal rim that takes wide gravel tyres or narrower road tyres, designed to pair with Campagnolo's Ekar GT groupset. This version has a Campagnolo N3W freehub body.

Highlights

• Aluminium C23 rim, 23 mm internal
• 2-Way Fit: clincher or tubeless
• G3 spoke pattern, 24 spokes per wheel
• Cup-and-cone bearings
• Claimed 1,690 g (780 g front, 910 g rear)

Versatile rim

The black anodised aluminium rim is 29.5 mm deep (28 mm in the milled zones) and 28 mm wide, with a 23 mm internal width shaped for smooth airflow. 2-Way Fit lets you train on clinchers and switch to tubeless, or fit a tube if you puncture a tubeless tyre.

Hubs and spokes

Black anodised aluminium hubs with oversize flanges run on cup-and-cone steel bearings, which handle lateral, radial and axial loads smoothly. Each wheel has 24 stainless steel spokes, bladed to 1.6 mm, in the G3 pattern, with self-locking aluminium nipples outside the rim that resist loosening under vibration. Each wheel is hand-assembled and checked by a Campagnolo technician.

Compatibility & fit

Disc brake only, AFS rotor interface, 12 mm thru-axles, 100 mm front and 142 mm rear. The Campagnolo N3W freehub body is for Campagnolo cassettes; 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. Campagnolo also makes the Zonda GT with N3W, HG and XDR freehub bodies. Cassette fitting and tubeless set-up are separate workshop services at Tune Cycles.
