If you take GSport's Birdcage rim and lace it to their new Roloway front hub, you’ll end up with one incredible front wheel.
ROLOWAY FRONT HUB (LEARN MORE)
The new Roloway hub is a precision sealed front hub with 3/8” in-bound axle bolts and two plastic hub guards. An oversized axle, bearing configuration and 7075-T6 aluminum hub shell is used for unmatched durability.
BIRDCAGE RIM (LEARN MORE)
At first glance the Birdcage looks like a fairly conventional “aero” style rim, but there is more to it than that. The first clue comes from the name; birds have hollow bones to save weight whilst retaining as much strength as possible, and the Birdcage rim has a hollow bead for the same reason. The rim’s hollow bead is still big and chunky to help reduce the chances of pinch puncturing or flat spotting the rim, but by creating a tiny hollow cavity inside it we can also keep the weight right down.
The next innovation was to adapt our cross-lacing design to the narrow inner wall of the rim. We managed to squeeze a few extra millimeters of spoke offset out of the design to help increase lateral wheel strength, and by carefully tailoring the rim’s cross-section we managed to match all the angles to the nipple so that the walls of the rim section act like the ribs inside the Ribcage rim, which helps to support the spoke nipples as much as possible.
