Mavic

Mavic is a French bicycle parts manufacturer, (its name an acronym for Manufacture d'Articles Vélocipédiques Idoux et Chanel), founded by Charles Idoux.

The company manufactures wheelsets, hubs, brakes, mudguards, cassettes, chainrings, headsets, computers, chains, stems, bars, cranks, bottom brackets, and children's pedal cars.

Recently, the company has expanded into producing technical shoes and apparel for cyclists. The company has employed innovative production with metals and especially alloys. Salomon had Mavic produce the edges for its skis and snowboards.

Mavic designed a spoke nipple mounted on the inside of the rim rather than from the tire side. This allows a rim to remain unpierced on the tire side with the exception of the valve hole. Less material is used in the rim. The Ksyrium wheelset was the first road to utilise this "fore" feature.

Mavic developed electronic gear-shifting system in the 1990s, first called Zap, then later re-engineered as Mektronic. The Mektronic was used by riders including Chris Boardman. However, it suffered engineering problems, notably that Boardman's bike shifted gear unpredictably, and was discontinued.

Road racing

Since 1973 the company has provided technical service to races. Yellow cars and motorcycles follow the race with wheels and bicycles. 

Mechanics change wheels or bicycles for any rider. Mavic has never made complete bikes so the service frames are provided by an outside manufacturer. Cannondale and Litespeed have also been used.

The top road wheels for many years were Ksyrium and Cosmic series. The Ksyrium has given way to the R-Sys. The R-Sys has tubular carbon fiber spokes that work in tension (like a traditional bicycle wheel) and compression (like a wagon wheel with wooden spokes). The spokes are held via "fore" technology at the rim and the TraComp ring at the hub. 

This allows lower spoke tension, which makes lighter wheels. The semi-aero Cosmic wheel is all carbon except for the rear hub. In 2009 Mavic released a recall on their R-Sys wheel. Having reports from customers on catastrophic failure during rides.

Mavic also makes clincher rims. The Mavic Open Pro is popular for everyday road use. CXP rims are the semi-aero counterparts.
