This revised sensor features an optimized bearing and seal, a robust design for high mechanical and thermal loads, and a CNC-milled aluminum housing in black anodized finish. It shortens shift travel and reduces shift time for faster gear changes, and can operate in both pull and push directions.
Show original supplier description
This updated version boasts an improved bearing and seal, ensuring enhanced durability and reliability under demanding racing conditions with high mechanical and thermal loads. Its robust design contributes to its precision and integration capability in the toughest racing environments. The FSS features a CNC-milled aluminum housing with a black anodized finish and a very low overall height. The sensor is capable of operating in both pull and push shift directions. It utilizes a reprogrammable Hall sensor with a spring-loaded measuring element that offers a ±3 mm travel and a force range of up to ±25 kg. This quickshifter is compatible with both standard and motorsport electronics (M RCK). The delivery scope includes the Fast Shift Sensor FSS, a 155 mm shift rod, and two ball joint heads. A note advises that when using the OEM rearset system, a shorter 135 mm shift rod is required (sold separately).
