The world has seven continents, each with its highest mountain peak. It is becoming more and more popular for climbers to try and climb all seven summits, which are also known as the Seven Sisters. Only a handful of people has succeeded. To reach the top of any of these is a huge achievement.
A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. The various load cell types include hydraulic, pneumatic, and strain gauge.
This allows the load cell to be hidden in the base of the pedals, where it is bolted to another piece of timber glued across the base. The clutch has a regressive action, with a linkage that pivots upwards on a couple of sealed bearings. The load cell is anchored at the top rear of the base. As the pedal moves into itâs travel, the stiffness decreases and the spring rotates upwards on a pair of bearings (hidden behind the bolts which are covering the spring in the pic below). You can see the 608-2RS bearings in the spring backplate, epoxied in place.
