Featuring Mavic's most innovative technologies, such as SUP welding and Fore Drilling, EX 823 Disc is the only true UST rim available for downhillers and freeriders. Ridden by the most talented and aggressive of them, it has proven to be strong enough to withstand the worst abuses.
Aluminium threaded eyelets (supplied with the rim)
ETRTO compatible size: 559 x 23
Recommended tire widths: 2.30 to 3.00
Valve hole diameter: 6.5 mm
Recommended nipple length: 16 mm
Do not use any rim tape
Maxtal: Exclusive to Mavic. An aluminium alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
Fore: Only one of the 2 rim wall is "drilled": - the rim is 4 times more resistant to fatigue stress - 20% increase in the rim rigidity to transfer all of your energy to the ground.
SUP: Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish. A welded and milled rim joint is extremely strong, eliminates shuddering when braking, and offers superior wheel balance.

Price isn't friendly but its the Best DH rim out, I use them for Street MTB and give them a REAL hammering, some off road too. Still stayed perfectly true after 8 months of abuse. Had them laced to hope pro 2's by CRC they done a good job. They work well with Schwalbe Furious Freds which is perfect for the street.
The finish is amazing still looks the same as when I bought it as long as you keep it clean, as well as the performance.
Looks good without added decals just make sure you line up the tyre decals with the rim decal.
Both came promtply and well built. thanks CRC
