Velocite’s new Venn Composite rims break the mold w/ filament wound, single strand carbon construction
Velocite has launched a new brand called Venn Composites to produce rims unlike anything we’ve seen before. There are two models, one using a filament wound construction and one using a continuous fiber construction to eliminate seams and misaligned patterns. We’ll start with the filament wound version:
The traditional method of making carbon fiber rims involves cutting pieces from a sheet of woven or unidirectional carbon, laying them into or over a mold, and layering those pieces in precise positions and directions to create a rim. It’s then pressed inside an outer mold, heated and cured, and then out comes a mostly finished rim.
Filament wound rims, however, pull carbon tow straight off the spool, run it through the resin and wrap it tightly around a mandrel in one continuous fiber. The strand is under constant tension, and it’s always wrapping itself in the exact spot it needs to be.
The benefits of this design are numerous. For starters, it’s mostly automated, so it’s consistent and perfect from rim to rim. Second, there’s no adverse angles to the carbon strands. Anytime a fiber is bent too severely, it creates a weak spot, and since nothing is woven on the body of the rim, there are no fibers being crimped around one another. Then there’s the efficiency. Not only are labor costs lower, material costs are, too, since there’s no scrap being cut away from carbon sheets.
From a rider’s perspective, it creates a stiffer rim that might just end up being less expensive, too…
