Wide-range cassettes solve the gearing problem but create a derailleur problem—standard short-cage mechs can't wrap enough chain to handle the tooth difference. SRAM's Force WiFli rear derailleur adds the cage length needed for cassettes up to 32 teeth while keeping the weight and shift precision you'd expect from Force-level components. If you're building a 10-speed road bike for mixed terrain or hilly routes, this is the derailleur that makes compact cranks and climbing gears work together.

The WiFli designation specifically means medium cage length, which handles the chain wrap requirements of a 32-tooth large cog. Standard Force rear derailleurs max out at 28 teeth, so the WiFli variant exists for riders who need lower gearing without stepping down to a mountain drivetrain. The extra cage length doesn't affect shift quality—SRAM's Exact Actuation cable pull ratio stays consistent across their 10-speed road lineup, so shift feel matches shorter-cage Force derailleurs.

Construction follows Force-tier material choices. The outer parallelogram link uses carbon fiber to reduce weight while the pivot hardware switches to titanium. These material upgrades over Rival sit in the middle of SRAM's road hierarchy, below Red but sharing the same shifting mechanism and actuation geometry. The derailleur bolts to standard road hanger mounts and works with any SRAM or Shimano 10-speed road shifter using cable actuation.... Read More
