Bortola A21W
Ultralight 21mm Profile, Straight-Pull, Wide Rim Alloy Clincher Wheelset

The Bortola uses our Japanese EZO bearings to give you the smoothest of rides, with low rolling resistance. Using our patented spoke braces which effectively increase the size of the flange for better power transfer, meaning when you pedal the force created isn’t lost in the wheel and propels you forwards. We have used straight pull spokes to really keep the power transfer at a maximum.
