The Venn 5028 C SL: 50mm deep, 28mm wide inside, carbon aero blade spokes and S&S ceramic bearings, 1190g a pair.
One wheelset for fast road and gravel. The 5028 TCD SL rim pairs a 50mm aero profile with a 28mm internal bed, sized for 35mm to 50mm tires. It is laced with carbon aero blade spokes, 20 at the front and 24 at the rear, on 36-tooth ratchet hubs with S&S ceramic bearings.
Wide enough for gravel, deep enough for the road.
At 36mm across its widest point the 5028 rim carries a wide tire 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 tires alike.
Twenty front, twenty-four rear.
A rear wheel carries more of the rider and takes every watt of drive torque, so it gets four more spokes. Spreading that load across 24 spokes lowers the peak load on each one, which keeps the wheel true under sustained power and on rough ground.
Carbon blade spokes.
All 44 spokes are carbon aero blades. Carbon barely stretches under load, 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 most at the top of the wheel, where the spokes move at twice road speed.
36t ratchet hubs with S&S ceramic bearings.
The 36-tooth ratchet engages across the full tooth face rather than through a pair of pawls, so power goes in the moment you load the pedals. Inside sit S&S ceramic bearings, chosen for low drag and long service life. Center Lock disc mount, 12 x 100mm front and 12 x 142mm rear thru axles. Tubeless ready, with tubeless tape and valves included.
No clear coat, your choice of surface.
The rim 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, where it costs the most, and leaves the carbon on open display. Gloss and matte weigh the same; the 25k surface adds 25 g per rim. All three cost the same.

FAQ
Riders who take one bike from tarmac onto gravel and want carbon spokes on both: gravel racing, fast road riding on wide tires, and long mixed-surface days.
1190g +/- 30g for the pair, calculated from its parts.
Shimano HG, SRAM XDR and Campagnolo N3W freehub bodies. 12 x 100mm front and 12 x 142mm rear thru axles, Center Lock disc mount.
Yes. They ship with tubeless tape and valves. The 28mm internal width suits 35mm to 50mm tubeless tires.
All three use the same 5028 rim. The 5028 S runs Sapim CX-Ray steel spokes on Venn RH05SL 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.
It is a matter of taste. Gloss and matte are bare carbon without a clear coat and weigh the same; the 25k surface shows a woven pattern and adds 25 g per rim. All three cost the same.
Yes. Shipping is free to every destination, and duties and taxes are prepaid to the US, the EU and the UK.
The Venn limited warranty: 5 years on the rims and 2 years on the complete wheelset, against defects in materials and workmanship.
