MTB Gear levers are available in grip shift (Sram) or trigger shift (Shimano Rapidfire or Sram). Levers can get worn over time resulting in inaccurate gear shifting. MTB levers are also more prone to damage picked up on the trail. As well as pairs of gear levers for 9 / 10 / 11 speed transmission set ups, Merlin stock individual shifters to cater for the current trend for a 1 x 10 / 11 / 12 transmission set up.
