New for 2015 is the FMB Slalom in Silica infused rubber. The new green rubber tires use a totally new rubber for FMB. The Silica-infused tread will roll faster due less tire deformation. They will also bite better in the cold. Be aware that Silica tires usually do not last as long as black rubber tires. The increase in performance means shorter tire life.

The FMB tires with the green sidewall are PRO tires. The latex PRO casing offers the best protection from sidewall cuts and tears. The new green casing preforms the same as the pink ones, it’s just a new color.
