CD - Couche Dure.
This process creates a micro surface hardness of the rim. It slows down braking wear and improves its durability.
Fore
Only one of the 2 rim wall is "drilled".
FTS-X - Force Transfer System X
A fruther improved FTS free wheel system to meet the demand of intensive MTB riding as closely as possible: stregthened pawls, self locking axle end screw to make the freewheel mecanism even more hard wearing and a new seal halving friction torque.
Maxtal
Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
QRM - Qualité de Roulements Mavic (Mavic bearings quality)
Mavic only uses high quality sealed cartridge bearings. On QRM wheels, they provide high durability thanks to double sealing (2RS or LLU) as well as high efficiency thanks to C3 internal clearance (low play, tight tolerances).
SUP - Soudé Usiné Process
A welded and milled rim joint is extremely strong, eliminates shuddering when braking, and offers superior wheel balance.
