⚡ At a Glance
- • Shifting Precision: Light, predictable indexing designed for accurate gear selection on six-speed setups
- • Best for: Commuters and recreational riders using Shimano-compatible 6-speed rear drivetrains
- • Not ideal for: Riders who need 7-speed or higher indexing or integrated multi-control setups
A rear twist-grip shifter intended for six-speed systems with an emphasis on light, precise indexing. SRS technology and the MRX twist format contribute to reliable, repeatable gear changes.
Light, precise shifts - with 2:1 actuation ratio
A 2:1 actuation ratio increases the cable movement produced by each lever action, allowing finer indexing steps across six gears. SRS technology is specified alongside the ratio to reduce slack and keep engagement consistent.
Cleaner, more accurate gear changes reduce missed shifts and make climbing or quick pace changes easier for everyday riders.
Intuitive twist operation - with MRX twist mechanism
The MRX twist format selects gears through rotating the grip rather than a thumb or lever, keeping the hand position stable on the handlebar. Mechanical indexing converts rotational movement into discrete gear steps.
Faster, more natural shifting in stop-start urban riding and on technical sections where retaining grip matters.
Straightforward Shimano fit - with rear 6-speed compatibility
Specified as fitting Shimano and designed for the rear position, matching the index spacing expected by six-speed Shimano drivetrains. Installation aligns with standard cable-pull and mounting for rear shifters.
Easy retrofit or replacement on compatible bikes, making the upgrade process simple for home mechanics and workshop technicians.
