Shimano Altus SL-M315-8R Rapidfire Plus Shift Lever

Description

Maximum Precise Shifting Performance

When navigating technical singletrack, reacting to fast-changing city traffic, or optimizing your cadence on a fitness ride, your cockpit controls define your speed and concentration. The Shimano Altus SL-M315-8R Rapidfire Plus Shift Lever is engineered explicitly for riders who demand fast, muscle-memory gear selection and want to completely eliminate shifter lag, thumb strain, and missed gear changes during aggressive acceleration.

Boasting a slim, space-saving body profile, this dedicated 8-speed right-side trigger shifter optimizes handlebar layout by tucking its mechanism tightly against the brake lever clamp to maximize grip space. Beneath the streamlined housing, Shimano’s Rapidfire Plus technology provides rapid downshifting, giving you the ability to dump up to three gears in a single lever stroke when approaching sudden climbs. Dual actuation is standard thanks to the integrated 2-Way Release mechanism, which lets you execute upshifts by either pulling with your index finger or pushing with your thumb. To isolate your ride from unexpected missed gears, the pre-installed OPTISLICK inner cable utilizes an ultra-thin, electrically coated layer that maximizes internal routing efficiency and blocks corrosion, ensuring smooth actuation much more effectively than standard, uncoated steel cables.
