Halo Caliber 6D 700c Aero Road Rear Wheel

A light and strong, deep aero non-carbon option for Time Trial use, or a great style statement on any performance road bike.

38mm deep section Aero 700c wheels with new reversed 6-pawl sealed bearing Halo Spin Master 6D hubs (Shimano or Campy compatible options).

Halo Aero spokes and alloy nipples with 20H radial front and NEW 16/8E (24E) rear spoke system for improved lateral rigidity.

Accepts regular clincher tyres.

Proven CNC alloy braking surface.

Rear wheels feature the highly unusual 16/8E spoke configuration:

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.
