Full Speed Ahead Ceramic Mega EXO Bottom Bracket
Full Speed Ahead has been testing ceramic bearings with our teams for the past two years. The results are great--teams and riders are convinced. Testing shows ceramic bearings can increase speed up to 4% or translate into 20 to 40 meters further traveled per kilometer. Ceramic bearings also last longer, perhaps 5-10 times more.
