The chainrings are also stiffer with new ramp pin design.
A tiny gearbox powered by a motor shifts three gears to precisely shift each gear and keep the derailleur cage parallel. Carbon fiber is used extensively to reduce weight. The WE groupset features a new FSA crankset based on existing models but with modifications to handle the demands of electronic front shifting. Specifically, the spider joining the chainrings to the cranks is a new shape for improved stiffness.
The chainrings are also stiffer with new ramp pin design. The crankset spindle is a 30mm forged aluminium BBEVO design, crank arms are hollow carbon and have been redesigned to reduce Q-factor by 3mm. The K-Force WE crankset will be available in lengths mm, mm, WE brakes are a dual pivot design similar to what has been in use this year but with increased reach and new quick release.
The cassette is grams and is available in , and To customise drivetrain shift settings and get reminders about battery charge levels and shift counts FSA have developed an app called the K-Force WE app. The Rotor Uno groupset under development will have hydraulic actuated shifting.
The Rotor Uno will have a disc brake option when released. Save my name, email, and website in this browser for the next time I comment. Fizik Antares R5 Kium review. FSA developed software apps, and worked closely on integration with headunit maker Wahoo and Garmin. The overall weight of the K-Force WE drivetrain is just 2,g. They are available in two lengths, with 6mm difference between them, to suit every hand size and rider type. This is complemented by the fact that both have reach adjustability to three different positions.
They will typically last around two years. The small LED lights on the front derailleur indicate battery status. In the unlikely event that it runs out of charge while out on a ride, the K-Force WE safety system will force the front derailleur into the inner chainring position.
The K-Force WE front and rear derailleur lack the traditional parallelogram design, but a unique electronic-driven gearbox moving the cage across the cassette with immense precision. This position means no ingress of water or salt making it well protected against effects of extreme temperature change. Efficient, precise functionality The benefits for this design approach are found in the optimum blend of efficient, precise functionality, long-term reliability, weight-saving and ease of use, charging and maintenance.
No parallelogram design The small LED lights on the front derailleur indicate battery status. Published by Jan-Willem van Schaik on 30 Mar
