What can I say, these are fantastic wheels and in fantastic condition. They have been serviced annually by Stripes and have never let me down. They are only used in dry conditions and kept in excellent condition. They are super quick, super light and have brilliant braking performance with the hybrid rim. These have the CULT ceramic bearings so have unbelievable performance and durability. I would have loved to keep them but can't justify keeping two sets of deep rims. Official Product Description: The Bullet(TM) Ultra(TM) are the brand new wheels by Campagnolo(R) that everyone was waiting for: an attractive design and the performance of a real leader. The special structure of the rim, combined with the oversize hub and the G3(TM) spoking solution with the DRMC(TM) (Directional Rim-Spoke Coupling) system, give the wheel and explosive responsiveness combined with great manoeuvrability and steering precision.
