The SL-M780 10-Speed mountain right trigger shifter features a low profile with XTR-like internals. The shifting is light action smooth and has a very consistent stroke up and down the gear range. The lower shift paddle has a wide platform making up- shifting that much easier. Cable adjusting barrels are mounted to the end of the shifters for on the fly fine tuning. The multi-angle lever action has a proven ergonomic design for a seamless rider/bike interface. As with the all Shimano trigger shifters, the upper lever shifts both ways; a simple and easy way of making this design one of the best trigger shifters on the market.
