Spec sheet for wheel builders (PDF)
Venn made the first filament wound bicycle rims, in 2015. The engineering behind Venn rims: the development since, step by step, to today.
Venn 620 TCD SL: a 62mm road rim for fast, all-day riding
The Venn 620 TCD SL is a 62mm deep disc-brake road rim weighing 420g (±15g). The depth gives real aerodynamic gains on flat and rolling roads while staying manageable in crosswinds, which makes it a rim you can ride every day, not only on race day.
Built around modern road tires
A 25mm internal width and 32mm external width give 28-32mm tires a round, well-supported shape for low rolling resistance, grip and comfort at sensible pressures. Available with 20, 24 or 28 spoke holes; ERD 520.5mm.
Moulded for a flawless wall
Articulated, multi-part tooling, layup preformed to net shape and controlled pressure and temperature give a fully compacted wall, virtually free of voids, and a surface that needs no clear coat.
Tubeless ready
The hooked bead takes tubeless tires as well as standard clinchers with inner tubes. Run tubeless with sealant and most punctures seal themselves before you notice them.
Tool access holes or a sealed tire bed
Order the rim with tool access holes (fit tubeless tape) or without them for a true tubeless tire bed that needs no tape at all. The sealed version takes external nipples only.
Your finish, your decals
Choose gloss uncoated or matte uncoated. Both show the bare carbon, with no paint or clear coat added. Decals: silver Venn Hanko, the original black Venn logo, or none.
