The days of choosing between lightweight, aero or durable wheels are over. Mad Fiber wheels deliver everything. Light weight. Aerodynamic performance. Durability and strength.
|Wheel Size:||700c (622)|
A Mad Fiber clincher uses the same groundbreaking design structure as our world-renowned tubular wheels. Its individual parts are effectively welded into a singular construct, for a wheel that’s made true, and stays true.
The clinchers use an aluminium tyre seat, because aluminium is the right material for the job. We can make it extremely light, and it holds up better than carbon when it comes to containing the very high pressure of clincher tire bead forces and dissipating brake heat. The result is a composite wheel with a more desirable balance of weight and strength than any other carbon clincher on the market—no rider weight limits, no tire pressure restrictions, no rim failures from heat buildup, and more consistent braking performance in extreme conditions.
Aside from the alloy tire seat, Mad Fiber clinchers use the same proprietary design as our tubular wheels—deep—aero rims with tensioned sidewalls that provide a smooth load path from the rim bed to the five-ply carbon spokes, which are securely anchored at the hub to create an optimized, tensioned structure.
The result of all this engineering prowess: A wheelset that accelerates with incredible snap, with an aggressively aero profile for more top-end speed and less power needed over the long haul.
Ceramic bearings offer a tremendous reduction in rolling friction. Our ceramic bearing upgrade replaces all four load-carrying bearings in the wheels, to give you every performance advantage.
Mad Fiber front wheels use a pair of 6802 ceramic bearings, one on each side of the hub. Rear wheels use a 6802 ceramic bearing on the left side, with a bigger 6902 ceramic bearing in the inboard location (rear hubs have four bearings, but the two housed within the cassette body never see rider load—the freehub is locked to the hub while pedaling, and only sees the weight of the cassette while coasting, so there’s no performance to be gained there).
Ceramic bearings are for serious competitors who have to have every advantage. But they also make good economic sense over the long haul—ceramics outlast conventional steel bearings many times over, and with enough time and mileage their durability outweighs the initial purchase price.
An interesting note: At lower speeds—30 km/h (18.6 mph) or less, rolling resistance plays a much larger role in the overall drag picture, so slower riders actually stand to gain more performance from ceramics. Elite racers operate at speeds where wind resistance is tremendously high, so rolling resistance is a much smaller part of the overall drag.
The new free-hub system, the result of several years development to achieve a lighter weight and higher performance hub assembly to enhance the Mad Fiber ride. Most notably this system allows for both Shimano and Campagnolo free hub bodies to be interchanged on the same wheel. (Mad Fiber’s previous free hub system didn’t permit this feature). The Shimano free hub body accommodates 9-speed, 10-speed and 11-speed cassettes.
Some Basic Points About The System
The left non-drive side end cap is permanently fixed to the axle and can not be removed. To remove the free-hub body, insert a 5mm allen key into both the left and right end caps and loosen by turning anti clockwise. The right side cap will unthread.
With the right end cap removed, the free hub body can be removed from the hub assembly by pulling straight out on the free hub with a firm grip. When assembling the axle and free hub body to not over tighten the end cap, not exceeding 4Nm. When using Shimano or SRAM 9-speed cassettes, use the included 1.85mm spacer behind the cassette. 10-speed cassettes require the 1.85mm spacer, plus the standard 1mm spacer, as supplied with the cassette. For 11-speed, no spacers are required. Should you have further questions please don’t hesitate to contact firstname.lastname@example.org
At Mad Fiber, all we do is make bicycle wheels—the most technically advanced, drool-worthy wheels in the world. This is an almost complete reboot of the bicycle wheel—an entirely different concept, and an entirely different way of building wheels. It wasn’t something that could be done at an existing facility—we needed fresh blood, and a whole new way of manufacturing. So we started our own company to do it, and rounded up some really smart guys, with exceedingly sharp pencils, some serious computational chops and manufacturing know-how. It also doesn’t hurt that we’re in Seattle, and able to make use of the region’s vast technology manufacturing base that exists to support Boeing. We exploit local Boeing sub-contractors for some parts production, but Mad Fibers are entirely American-made, built in a nearly 100-year-old converted bakery building where we now cook up the world’s tastiest bicycle wheels.
