101 Clincher
Available mid-April 2010! Incorporating all that we’ve learned in 21 years of working with carbon fiber, the 101 is the first aluminum wheelset to utilize Zipp’s cutting-edge aero technologies. Featuring the world’s only fully toroidal (pdf) aluminum rim in a 7000-series high-strength alloy, the 101 actually has more in common with Zipp’s carbon wheels than it does with any other aluminum wheel that’s ever been made. Like our carbon wheels, the 101 is a product of Zipp’s rigorous wind tunnel development process. Like our carbon wheels, it outperforms even deeper-section models from the competition. Like our carbon wheels, the 101 is handbuilt at our facility in Speedway, Indiana. Designed for racing and everyday training, the 101 balances weight, reliability and aerodynamics. Its 30mm profile is deep enough to take advantage of Zipp’s exclusive toroidal shaping while holding the 101’s weight to just 1484 grams. The result is a wheelset that weighs the same as the industry’s aluminum benchmark but saves up to 42 seconds over 40km. A 24.5mm rim width maintains the 101’s aerodynamics even with 25mm tires. But the 101 can also be used safely with tires as narrow as 21mm – unlike other clincher rims of similar widths – because the rounded toroidal shape is narrower at the hook bead than in the middle. The 101’s wide stance also resists pinch flatting, improves lateral stiffness, and provides a stable platform for precise handling on rough surfaces. The 101 features Zipp’s 88 front and 188 rear hubs with an 18/20 spoke count.
88/188 Hub Technology
Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. The wire EDM-cut hub internals are the most precise. The SHIFT spoke hole technolgoy is the most durable. When it comes to precision and performance, there's really no comparison. Read More
Steel Bearings
One thing that has set the Zipp hub apart since the beginning has been the bearing design. Zipp is the only company in the world specifying Swiss made ball bearing cartridges, but these are not even standard Swiss made cartridges, they are highly specialized. Since most stock bearings of the size used in bicycle hubs come from the machine industry, they are invariably designed for higher rotational speeds and generally lower loading, and usually no shock loading. Working with a family-owned Swiss bearing manufacturer, Zipp is able to define certain key criteria to bearing smoothness and long life, and develop the finest cartridge bearing every introduced into the cycling industry. To start with, standard bicycle bearings are usually toleranced at 50 millionths of an inch. This is done by blowing them up a graduated tube with air, and guarantees that all balls are within 50 millionths of an inch of each other in diameter, and any individual ball is round within that same 50 millionths of an inch spread. High precision balls utilized in most company’s high end products up this spec to 25 millionths of an inch to ensure better roundness of the balls, and ensure smoother rolling. Zipp ball bearings are specified to 10 millionths of an inch tolerance, guaranteeing that they are at least 2.5 times rounder and better matched than most company’s ‘high precision’ balls, and more than 5 times tighter than most ‘precision’ balls. The measurement reports below show two ‘round’ items, the first measuring 10 millionths round, the second 20 millionths round.
Wire EDM
Electron Discharge Machining allows us to cut the materials for our rear hub drive internals after they’ve been hardened through heat treating, negating the warping and imprecision caused by the heat treating process. Read More |
