Mavic Crossmax SL wheels - first look

French company's lightest mountain bike wheelset

French wheel manufacturer Mavic has redesigned the Crossmax SL, which it claims is nearly 100g lighter than the next lightest wheelset in the company’s line, the Crossmax SLR. Weights range from 1,390g to 1,520g per pair, depending on wheel size.

Claimed weights for the Crossmax SL wheelset:

  • 26in - (1,390g per pair, 630g front / 760g rear)
  • 27.5in - (1,470g per pair, 665g front / 805g rear)
  • 29in - (1,520g per pair, 690g front / 830g rear)

In addition to being offered in all three wheelsizes, the Crossmax SL is compatible with most popular axle configurations, including front and rear quick-releases and front and rear thru-axles. A Lefty-compatible version will also be available. Mavic will offer an XD driver body (to be sold separately) for the Crossmax SL for SRAM 1x riders.

Mavic was able to shave weight from the Crossmax SL wheelset with a new rim profile and through the use of the company’s proprietary ISM 4D machining process, which shaves material from the exterior of the rim.

The new rim measures 23mm externally and a rather narrow 19mm internally. Mavic’s FORE spoke insertion drilling leaves the interior wall free of spoke holes for UST tubeless compatibility without the need for tubeless tape.

The rims are connected to the hubs with 20 bladed Zicral spokes. The front wheel uses a two-cross lacing pattern on both sides, while the rear wheel gets radial lacing on the drive-side and two-cross lacing on the non-drive side.

The Crossmax SL wheelset will be available in September for US$999. UK and Australian pricing has not yet been announced.
