M3 Carbon Tubular Disc

Material: CARBON Depth: 38mm
Weight (Set): 1,470g Width: 24mm 

If you're in the market for a set of bomb proof carbon wheels for either road or 'cross, then you've probably already made the correct assumption that the depth of the M38's are 38mm. The M38 is a solid 24 millimeters wide, which means you can run lower PSI for added grip while carving around the last corner with unparalleled confidence to win the race.

Tested in the pro ranks on the road and 'cross by some of the top US riders, this is the perfect wheel to slice through the muddy sections at your favorite 'cross race or earning your rainbow bands at the Wednesday night World's!

The M38s are laced with Sapim's CX-Ray spokes, their most popular bladed model, which are capable of withstanding a claimed one million load reversals of fatigue testing while still saving weight courtesy of their proprietary butting. They connect to proprietary Mercury Pro hubs, which engage with three pawls for a nearly immediate responsiveness that takes advantage of the rims' low rotational inertia. The front hub has an extra-wide 60 millimeter flange for reduced flex under hard efforts and confident stability at speed. Both hubs have oversized axles that tapers to accommodate a traditional quick release and two and four over-sized bearings in the front and back, respectively.

included in the box

This wheelset comes installed with Mercury rim strip and front 15mm end caps.  Included in the box (when purchased from Mercury): 12mm endcaps, QR endcaps and QR rear axle w/ endcaps.  If you're purchasing from another source, confirm with that vendor.

WARRANTY: 2 yr warranty extends from the date of purchase, applies only to the original owner, and is not transferable.
