Zipp has unveiled revamped versions of its 808 Firecrest and 858 NSW wheelsets, touting reduced weight, improved aerodynamics and less rolling resistance at a more affordable price.
According to Zipp, the updated hoops now tip the scales at 10 to 15% less weight, while the hookless rim design features a 21% wider internal width, allowing for the use of 28mm tubeless tires.
Also, in addition to going full disc brake, the new wheelsets get Zipp’s proprietary Total System Efficiency technology (TSE), which still allows for the use of tubes, but only when used with tubeless tires in order to ensure safe retention on the hookless bead.
In the case of the 808 Firecrest, keen observers will note that the rim deep has been slightly decreased for 82mm to 80mm, resulting in a claimed 280 gram reduction in weight, while Zipp’s complex ABLC dimpling technology has said to improve the wheels aerodynamic signature, mirroring the anti-turbulence sawtooth shape of the more expensive 858 NSW.
The revamped 858 NSW feature Zipp’s unmistakable sawtooth rim design, albeit with a slightly shallower rim profile, once again reducing weight by some 15%, while the wheels spin on the brand’s Cognition V2 Hubset engineered with the 54 POE Axial Clutch V2 mechanism, resulting in quicker engagement, lower friction and improved durability.
Like the 808 Firecrest, the 858 NSW is also disc brake only and optimized for use with 28mm tubeless tires.
The new Zipp 808 Firecrest and 858 NSW wheels are available directly from Zipp, or through authorized dealers, which can be purchased as a set, individually, or mixed and matched.
