Stephen Cummings' stage-winning CeramicSpeed chain used at Criterium du Dauphine

Stephen Cummings (Dimension Data) put in an outstanding individual effort on Sunday’s finale stage 7 at the Criterium du Dauphine. His third stage victory of the year, Cummings formed part of the breakaway that went after around 35 kilometres. Cummings then went on to break solo with 50 kilometres to go, finishing ahead of the groupe maillot jaune by nearly four minutes.

Before the stage, Cyclingnews spotted a special hand-finished chain on Cummings’ bike. The chain, supplied by CeramicSpeed, is dubbed the ‘UFO’ – Ultra-Fast Optimized. It certainly lived up to its name during the stage.

The ultrafast racing chains are carefully selected from high-quality manufacturers and finished by hand in Denmark. The chains are completely taken apart, stripped, rebuilt and hand finished with a synthetic treatment to reduce friction and a power saving of a claimed 3-5 watts.


The single-use chains are designed and manufactured exclusively for a single, high performance race day. Not suitable for wet or muddy conditions due to a lack of corrosion protection, the chain has an optimal life span of around 320km. The UFO treatment was also used to coat the Shimano Dura-Ace cassette and ROTOR noQ rings (53-38), which extends the life span of the treatment slightly.

At €119 per chain, even WorldTour teams will be using the chains sparingly. However, with the stage win under their belt, Team Dimension Data and Cummings alike will be elated with the result.
