In his 11th season as a professional, Japanese rider Yukiya Arashiro begins his 2018 campaign as he did in the previous season at the Tour Down Under.

While the updated 2018 Merida Reacto was first seen back in June at the Criterium du Dauphine, Arashiro receives an updated paint job and new chainrings on a bike that is otherwise very similar to last season.

Bahrain-Merida used SRM Origin cranksets in their debut season and the German power meter company have updated the crankset for 2018 with Shimano Dura-Ace R9100 series chainrings, resulting in a gucci, black and raw carbon unit.

During 2017, Bahrain-Merida finished their Merida framesets in a red, gold, but predominantly metallic blue base colour design. For 2018, the team switches the metallic blue base colour for a more contrasting black, which not only matches the crankset but the Dura-Ace groupset and Fulcrum Speed raw carbon wheels and allows the additional colours to pop out on the bike.

Arashiro chooses to pair his aero frameset with the equally wind cheating Vision Metron 5D integrated handlebar and stem combination, which is only wrapped with tape on the drops and left bare on the tops for maximum aerodynamic performance.

Italian saddle specialists Prologo provide Bahrain-Merida with saddles, customised with bands of team colours on the rear of the seat.
