M5 Carbon Rims

M5 clincher carbon rims are coming our way.

With some unique points, like having metal strips buried BENEATH the carbon in the braking areas and spoke nipple seats, these rims have a lot of promise. The two strips buried in the braking areas reinforce the carbon walls against blowout of the from outward pressure caused by the beads when things heat up, and also move heat away and distribute it all around the rim for more efficient cooling. Local heat buildup can cause blowouts, and also rim bowing (via resin softening) in the worst possible place. This can happen on downhills or any time there is a lot of high speed braking, and high speed plus problems don't have great ways to end for the cyclist. These two strips are a great way of answering this issue.

The other strip reinforces the spoke holes, allowing for greater spoke tensions, the bane of most carbon rims. Ever seen blips in the rim walls under the nipple seats? This spreads the load over a larger area, allowing for no local high pressure spots caused by spoke tensions. Another innovative solution that M5 have developed.

Only 38mm rims have been released to date, and we are offering them built with M5's own hubs laced with Sapim CX-Ray spokes, and also DT Swiss 240s hubs laced with DT Swiss Aerolite spokes. Both are good hub/spoke options that we feel offer the most when combined with these great carbon rims.
