Mercury 700c Road Rim

Wind cheating 30mm deep section aero rim, produced in Auralite Nb-A super alloy, making a very light and rigid rim. CNC machined finish brake surface. Perfect for time trial or long stage race.

16/8E explained:

The hub offers an extra wide offset left hand non drive spoke flange (to increase the A-frame type support structure of the spokes to the rim) and counter balances the,common,resulting uneven spoke tension problem by having only 8 spokes on the heavily offset side vs 16 on the almost straight dished drive side.

The rim and the hub have been specially drilled to accommodate the 16/8E configuration to result in the spokes being "Evenly" spaced in the rim's circumference.

All of the rear spokes are "crossed" to provide a tangential structure to spread the drive torque throughout all of the 24 spokes (rather than having some spokes in a radial configuration that are unable to effectively help transfer torque drive from the hub to the rim).

Halo's theory being that if you spread the drive torque over all 24 of the rear spokes (rather than just some of the spokes on the drive side alone), then this further divides it up, and thus reduces the torque transferred to each spoke.
