Ksyrium SR Clincher Wheels

Throughout Mavic's 100-plus-year history, the French manufacturer has introduced a number of revolutionary product, for better or worse. Some, like the ZMS electronic derailleur (1994) were unsuccessful in the market, but revolutionary to the industry, especially considering two of the three major component manufacturers have recently released their own electronic groupsets. Mavic introduced other products like the Cosmic wheel (1995) with much better market results, as well as forever influencing aerodynamic wheels that are commonplace in today's professional peloton. But jump back a few years to 1999, when the Mavic Ksyrium Wheels were unveiled. It was the first aluminum rim to incorporate Mavic's Fore drilling, a process where only one of the two rim walls is drilled. This allowed the rim to be stronger (less holes=stronger rim) and lighter since rim tape was no longer necessary.

The Mavic Ksyrium SR Clincher Wheels may be several generations younger than the original Ksyrium Wheel, but it still has many of the same characteristics as its predecessor, along with several new improvements. The SR rims get the same Maxtal aluminum rim and Mavic's Inter Spoke Milling (ISM) for added weight reduction. Mavic also incorporated their UB Control milling technology, a method in which braking surfaces are milled to improve friction (and thus braking performance) and eliminate brake shudder.

The front wheel has 18 radially laced Zicral spokes. The 20-spoke rear wheel uses Tracomp tubular carbon spokes on the drive side and Zicral spokes on the non-drive side. The Tracomp spokes are laced in a two-cross pattern for optimal power transfer during acceleration.

Carbon fiber shells and aluminum flanges add aesthetic appeal to the Ksyrium SR's oversized hubs. Aside from good looks, the hub design also sheds a few grams from the overall weight, adding function to the fashion. The SRs also come equipped with Mavic's QRM+ bearings; they're double-sealed for longevity, and each hub allows for micro-fine preload adjustment without even removing the wheel from the bike.

The Mavic Ksyrium SR Clincher Front Wheel includes Mavic's BR601 quick-release skewer. The Mavic Ksyrium SR Clincher Rear Wheel includes Mavic's BR601 quick-release skewer, a Zicral spoke-specific magnet, and a truing wrench and bearing adjustment tool. The front wheel weighs 645 grams, and the rear tips the scales at 800 grams. The total wheelset weight is 1445 grams.

This wheelset is part of Mavic's MP3 extended warranty program. The acronym stands for Mavic Product Protection Plan, and it provides you with two years of almost unlimited no-fault protection from Mavic. More details can be found on the MP3 website . Please note that MP3 coverage must be purchased within 5 days of the date that you receive your wheels. You'll get an email from us the day after your online wheel purchase, containing the retailer and product codes that you'll need to register your wheels on the Mavic MP3 site. You'll also need the serial numbers that you'll find on your wheels. The cost for this coverage is approximately 8% of the retail cost of the wheels.
