    Spares and accessories for Shimano Di2 and Campagnolo EPS electro-shifting systems.

    Refine By Clear All

      Unlike some upgrades, Electronic components offer an instant, very noticeable difference over their mechanical counterparts. Quick, effortless and smooth shifting – even under heavy load, comes as standard. Shimano electronic gearing also allows for multiple locations for shifter buttons, such as sprinter buttons or Time Trial / Tri bike specific ones. Whether it’s the latest Sram eTap Wireless technology or the established Shimano Di or Campagnolo EPS systems, electronic gearing is set to stay. As well as full electronic groupsets, Merlin also stock Electronic gear sets as well as spare batteries and other components.
