ZIPP 808 FIRECREST TRACK TUBULAR REAR WHEEL

  • Share on social media

Zipp 808 Firecrest Track Tubulars are probably the fastest practical choice for the banked oval. Double discs on the track might be faster, but they’re harder to control, and much heavier.

The 808 Firecrest Tubular rim you see here is the same as you’ll find on the road. The great thing about the 808s is they handle like much shallower wheels. The Firecrest shape is the secret. The blunt end and flattish profile not only reduce low pressure zones on the leeward side of the wheels, but through smart tuning, Zipp was able to move the focal point back, so that steering would be easier-which means less attention needs to be paid to riding fast and less arm strength needs to be used to hold the wheels in the direction you want them to go.

The rim depth is 82mm deep with a max width of 27.5mm. The cross-section looks very much like a super-long U, with a blunt edge on the spoke side. And, with a tire installed, the leading and trailing edges seem nearly identical. This overall shape, and further enhanced by the ABLC dimple pattern means that even though the wheel appears very deep when slicing through a pure headwind (zero yaw), it appears relatively shallow when getting hit by a crosswind (higher yaw angles), which happens twice a lap on a tack. The result is that the wind almost sees the 808’s as disc wheels when you’re going straight, and sees 404’s or shallower when you go through the turns.

Not only does this mean added speed overall, but it also means less arm strength and less focus to pilot the bike exactly where you want it to go. And accelerating wheels that weigh only 1805g per set is easier, all things being equal, than most of the commercially-available track hoops.

Cool note: The exposed spoke nipples, which are liked because you can true the wheel without special tools and with the tire still glued on, are totally hidden from the wind when the tire is the leading edge. Those spokes are the fastest available, Sapim CX-Ray, which are thin blades capable of holding high spoke tension. Twenty radial spokes in front and 24 two-cross in back.

The spokes are J-bends are laced to Zipp’s 333 track hub. The name is for a standard track length. The shells are made of 7075 aluminum alloy and feature solid flanges for stiffness and strength. Axles are 15mm in diameter and made from stainless steel. The axles run on sealed cartridge bearings, which are easy to service thanks to the wide wrench flats. Likewise, the axle nuts are tightened by a 6mm Allen key The rear hub has a larger drive-side flange. This allows Zipp to achieve equal tension on both the drive- and non-drive-side spokes, making the wheel stronger and stiffer. Weights are low, with the front weighing in at 215g and the rear 270g.

The wheel is delivered with a Zipp valve extender designed to thread into valve stems that are at least 37mm long and feature a removable valve core.

The Zipp 808 improves any bike its on. It can be paired with an 808, or with a shallower wheel in the front or a deeper wheel in the back, depending on your strengths, how you ride, and the conditions you ride in. There’s a slight chance that the 808 rear won’t fit between super-narrow chainstays found on some pursuit bikes. Check first.

The Zipp 808 Firecrest Track Tubular is like having climbing wheels that outperform discs.

ZIPP 808 NSW CARBON CLINCHER FRONT WHEEL
ZIPP 808 NSW CARBON CLINCHER FRONT WHEEL

Zipp’s 808 NSW Carbon Clincher is the debut of a new line for Zipp, and a big step forward in wheel technology. The wheel is faster by three to four watts , stiffer, rolls better, and stops quicker. It not only eclipses their 808 Firecrest, but distances the competition. NSW is short for Nest Speed Weaponry, the top-secret facility within Zipp where the latest ideas are hatched and incubated. Some of their work has already been seen in the 404 Firestrike wheels, but those were limited-production. This is a full-on run. It’s already been proven in competition. Weeks before it was released, it dominated the 70.3 world championships going both first and second. Then at the world championship team time trial, the 808 NSW front was paired with a disc rear and also went one-two. The first big change, and probably the most important, is the evolution of the rim shape. They’ve held by the 82mm rim depth that has proven so valuable, but they widened the rim at the brake track, up from 24.73mm to 26.44mm, slightly increased the max width from 27.5mm to 27.8mm. This makes the rim appear to have more vertical sides than in the past. The dimpling pattern as been modified. They call it Aerodynamic Boundary Layer Control, or ABLC, and the new pattern, which they call Sawtooth, thanks to the wrapping of the dimples over the sides. Basically, the pattern is designed to reduce drag in high yaw (crosswinds) and improve crosswind stability. The brake track has been improved with their Showstopper technology, which is molded grooves that help channel water off the rim as it spins and cool the track as well. Better, more consistent braking in the wet, in the dry, and even when you’re dragging the brakes. The last bit of rim improvement is probably the flashiest. It’s their ImPress graphics, which essentially screen the logo onto the rim. This is lighter, and more aero than Zipp’s super-light, super-thin, stickers. Zipp also redesigned their hubs. They call it Cognition. What you need to know is that that they’ve improved both front and rear designs. The front, weighing 110g, features a scalloped edge for the spoke beds where the pressure from the spokes is more evenly distributed and doesn’t deform the bearing bore under high loads, like when you’re sprinting out of the saddle. The rear, weighing 225g, has a new pawl design with an Axial Clutch, which reduces pawl drag when coasting. Sapim CX-Ray spokes are used: still the best in the business. Even with the wheel being faster and stiffer, the overall weight has dropped by 75g to 1810g, 830g in front, 980g in back. As should be expected, you can choose between a Campagnolo-compatible 9/10/11-speed cassette body, and a Shimano/SRAM body. You can also pull these bodies and install a SRAM XD cassette body for even more diversity of applications. The wheels, sold individually, come in a Zipp wheel bag )which can be secured to a second such bag), a black anodized Zipp titanium skewer, a Zipp valve extender, a Zipp butyl tube, Zipp Platinum Pro Evo pads (please specify), And Zipp rim tape. As a set, these are smoking fast wheels. If you go with the 808 NSW front, it could be paired up with a rear disc for more speed. If you go with the 808 NSW rear, it could be paired up with a mid-depth front for more steering control. The Zipp 808 NSW Carbon Clincher will leave others desperate to catch up....

ZIPP 808 FIRECREST DISC TUBELESS CLINCHER REAR WHEEL
ZIPP 808 FIRECREST DISC TUBELESS CLINCHER REAR WHEEL

If you’re looking for flat-out speed on your disc-brake road, time trial, or triathlon bike, the Zipp 808 Firecrest Disc Tubeless Clincher is the schizzle. It is wickedly fast, stable in crosswinds, and light. The depth is such that it’s like riding double discs, just so much easier. They accelerate better, handle road vibrations and potholes better, and don’t get pushed around in the wind nearly as much. They’re light enough to race on the road, and the aerodynamics are so impressive that triathletes and time trialists needn’t look for disc wheels. Some folks who race against the clock might want to pair an 808 front with a disc rear for the ultimate in speed, or a 808 rear with a 404 front to deal with crosswinds. But no matter how you choose to ride them, these are speedy. The rim is more than tough enough for off road use, but Zipp’s stated intentions was to maximize speed on the road. The blunt-edged rim shape, which Zipp embraced with the Firecrest line, is markedly better than old-school NACA-inspired airfoils. First, the wider shape works better with wider tires. Second, the blunt edge, when paired with Zipp’s dimples, makes the shape less susceptible to being pushed around in crosswinds. This Firecrest 808, which is similar, but not identical, to the rim brake version. The shape and layup has been tweaked to work better with not only disc brakes, but also wider tires. First, Zipp moved material around, because they didn’t need the brake track any longer. Second, they advanced their ABLC dimples all the way up the rim’s sides. Third, they tweaked the shape of the rim to work with even wider tires. The depth remains 82mm, the 808 standard. But the width has been narrowed slightly, to 26.4mm from 27.5mm. And the internal width has been widened slightly to 19mm. That depth means you don’t want to run a tire narrower than 23mm, and, if you want it to perform best in the wind, you’ll go with 25mm wide tires. Wider works as well, though not as aerodynamic. Zipp employs their 77/177D hub set, which was purpose-built for disc braking. There are 24 aero Sapim CX-Ray spokes, both front and rear. A cross pattern is necessary in front to counter the forces of braking. The flanges are slightly taller to work around the six-hole rotor mounts and the 17mm axle. While you can see that the spokes have a two-cross pattern, it actually possesses the lateral stiffness of a three-cross thanks to the size of the flanges and the orientation of the spokes. The benefits of the design are more aero and shorter spokes. The rotor mounting method is six-bolt. The front wheel weighs in at 950g, the rear 1025g. Maximum recommended tire pressure is 125psi, which should be overkill for any tire you’d want to install on this wheel. Maximum recommended rider weight is 250lbs. For rear wheels, Zipp offers both a Campagnolo-compatible, and Shimano/SRAM-compatible cassette body. The latter comes with a spacer for 9/10/11-speed cassettes. In both cases, the 177D hub body allows you to install a SRAM XDR Driver body for super-wide range gearing. The wheel comes with quick releases and endcaps to convert the hub for thru-axle or quick-release use. The included endcaps can convert the front wheel from 100x12mm to 100x15mm to quick release. The rear has endcaps for 142x12mm and quick release. They also include a spacer to convert the cassette body from eleven-speed to ten-speed. Also included are: rim strip and a tubeless valve, both installed at the factory, and a valve core removal tool. The Zipp 808 Firecrest Carbon Clincher Disc Brake wheelset is for speed, first, and foremost....
