Carbon Care

A crash should not cost you a whole wheelset. If you damage a Venn wheel in a crash within 5 years of buying it, Carbon Care replaces the damaged wheel at 40% off its list price (the recommended retail price, not the price you paid).

  • Covers accidental crash and impact damage. Manufacturing defects are separate and are always repaired or replaced free under the warranty.
  • 40% off the list price (recommended retail price) of the damaged wheel, front or rear, not off the price you paid. If both are damaged, the discount applies to the full wheelset.
  • Available to the original owner for 5 years from the purchase date.
  • To claim, send proof of purchase and photos of the damage. One claim per incident.
  • Non-transferable.

01

WIDE ENOUGH FOR GRAVEL, DEEP ENOUGH FOR THE ROAD

At 36mm across its widest point the 5028 rim carries a wide tyre cleanly, and the 28mm internal bed lets you run it at low pressure for grip and comfort on loose ground. Fifty millimetres of depth keeps it quick on tarmac. The hooked bead takes tubeless and clincher tyres alike, so one wheelset covers the road ride and the gravel race.

02

TWENTY FRONT, TWENTY-FOUR REAR

A rear wheel has a harder job than a front one. It carries more of the rider, absorbs every watt of drive torque through the freehub, and takes the dish asymmetry that a cassette forces on it. So the 5028 C SL is laced accordingly: 20 carbon aero blade spokes at the front, where the work is lighter, and 24 at the rear, where it is not. Spreading drive torque across 24 spokes means no single spoke sees a large share of it, and that is what keeps a wheel in tune when the loads are high and repeat every pedal stroke.

03

PREMIUM COMPONENTS

The 36-tooth ratchet hub engages across the full tooth face rather than through a pair of pawls, so power goes in the moment you load the pedals and keeps going in under torque. Inside it sit premium S&S ceramic bearings, chosen for low drag and long service life rather than for a spec-sheet line. The wheelset is fully tubeless-compatible and ships with tubeless tape for either traditional clincher or modern tubeless setups.

In depth

Rim Profile

50mm deep, 28mm wide inside and 36mm outside (33.5mm at the bead): sized for 35 to 50mm tyres. The Venn 5028 TCD SL rim weighs about 380g and carries no clear coat.

Carbon Blade Spoke Technology

All 44 spokes, 20 front and 24 rear, are carbon aero blades. Carbon fibre's near-zero elongation under load means the spoke does not stretch and hand energy back on the next pedal stroke, so power arrives at the rim as forward motion rather than as wind-up. The bladed profile presents a narrow edge to the airflow, which matters more than most riders expect: spokes travel through the air far faster than the bike does, and the top of the wheel is moving at twice road speed.

Uncoated Finish, Your Choice

The 5028 C SL carries no clear coat, whichever surface you choose: gloss, matte, or the 25k filament-wound pattern. Leaving the coating off keeps weight off the rim perimeter, where it costs the most in rotational inertia, and it leaves the quality of the underlying carbon structure on open display with nowhere to hide. Gloss and matte weigh the same; the 25k filament-wound surface adds 25 g per rim. All three cost the same.

Choosing a 5028 Build

All three use the same 5028 TCD SL rim. The 5028 S runs Sapim CX-Ray steel spokes on ratchet hubs with sealed steel bearings, for 1270g. The 5028 C SL saves 80g with carbon aero blade spokes and S&S ceramic bearings, for 1190g. The 5028 HE1 runs Venn's own Helix-01 hubs with 72-tooth helical engagement, for 1380g. Take the S for value and steel spokes any shop can service, the C SL for the lightest set, and the HE1 for instant engagement under power.

Questions riders ask

What kind of rider is the Venn 5028 C SL for?

Riders who take one bike from tarmac onto gravel and want carbon spokes for both: gravel racing, fast road riding on wide tyres, and long mixed-surface days. The 20 front / 24 rear lacing keeps the wheel true under sustained power and on rough ground.

How much does the Venn 5028 C SL weigh?

1190g +/- 30g for the pair, calculated from its parts: the 500 C SL build with the 5028 rim, which is 35g heavier per rim.

Why 20 spokes at the front and 24 at the rear?

Because the two wheels do different amounts of work. The front wheel steers and carries less of the rider, so 20 carbon aero blade spokes is a sound number for it and saves weight where it can be saved. The rear wheel takes drive torque, carries more weight, and is dished around the cassette, so it gets 24. Spreading that torque across 24 spokes lowers the peak load on any one of them, which is what keeps the wheel true over a long season.

Which freehub options are available for the 5028 C SL?

Shimano HG, SRAM XDR, and Campagnolo N3W freehub bodies are available, covering all major 11- and 12-speed road drivetrains. Choose your freehub at checkout.

Which tyres work best?

The 28mm internal width is made for 35 to 50mm tyres, from fast road tyres on rough tarmac to gravel race tyres, tubeless or with inner tubes. Tubeless tape is included.

Which 5028 build should I choose?

All three use the same 5028 TCD SL rim. The 5028 S runs Sapim CX-Ray steel spokes on ratchet hubs with sealed steel bearings, for 1270g. The 5028 C SL saves 80g with carbon aero blade spokes and S&S ceramic bearings, for 1190g. The 5028 HE1 runs Venn's own Helix-01 hubs with 72-tooth helical engagement, for 1380g. Take the S for value and steel spokes any shop can service, the C SL for the lightest set, and the HE1 for instant engagement under power.
