Top swing, dual pull and multi fit make the FD-M315 compatible with most 7/8-speed double arrangements. The layout focuses on uncomplicated installation and dependable everyday use.
Smooth gear changes - with top swing and dual pull design
Top swing places the clamp and mechanism above the chainring plane, offering clearance on many frame shapes. Dual pull accepts either top-pull or bottom-pull cable routing, increasing installation flexibility.
Reliable shifting across the chainring reduces chain rub and missed shifts, so riders spend less time adjusting and more time riding.
Broad drivetrain compatibility - with 7/8-speed double specification
The FD-M315 is indexed for double chainring spacing used by 7 and 8-speed systems, matching chain width and ring pitch. Multi fit mounting adapts to different clamp diameters or braze-on positions.
A wide range of frames and older drivetrains can accept the unit, making it a practical choice for repairs and upgrades on commuter and older mountain bikes.
Easy maintenance and installation - with a straightforward mechanical layout
Conventional clamp and adjustment screws provide familiar setup steps for most mechanics and home wrenchers. The mechanical nature avoids electronic calibration.
Routine adjustments and servicing stay simple, keeping workshop time and complexity low for regular maintenance cycles.
