It’s not often that professional riders get to kit out their team issue bikes with dazzling bits of bike bling. But who can say no to a bit of gold, especially when it comes as standard?

While sprinter Theo Bos switched from Belkin to MTN-Qhubeka over the winter, the South African team made a change too, from Trek to Cervélo.

The brand had found itself without a top-level team to sponsor for the first time since 2010, after Garmin merged with Cannondale at the end of last season.

Its range-topping aero offering, the S5, was Bos’s bike of choice for the season-opening Challenge Majorca and he lined up at the Trofeo Playa de Palma with his full sprint-specific set-up: deep carbon rims and a time trial-specific saddle to help him get in as aerodynamic a riding position as possible.

While proven to be exceedingly slippery through the air, the highly sculpted tubing and awkward lines of the S5 have divided aesthetic opinion in previous incarnations.

Yet the matte black finish and loud white decals mean the MTN version looks clean and classic. With that gold chain, we’d even go as far as to say it’s a modern day masterpiece.

Bos’s bike is equipped with 60mm front and 95mm rear ENVE SES carbon-fibre wheels to aid the S5’s slippery aerodynamics. The KMC X11-SL gold chain adds little more than a welcome touch of bling, and Bos favours the feel of Rotor’s Q-Rings over standard rings.
