Q. What are the specifications of the crank set?
The crank set is 44T high precision unit. The crank arm length can be of 165mm or 170mm depending on model & availability from the manufacturing partner. The material used is high tensile steel.
Q. There is something wrong with the crank / the crank seems to be loose. What should I do?
The crankset usually have 2 touch points. (a) From one end it is linked with the bicycle main frame with a big nut and attached to the BB cartridge (b) on the other side it is linked with the pedals. On both sides it is linked with a screw mechanism. With time or rough usage, the threads might get loose, so it just needs some tightening. To understand correct procedure of tightening the crank set, please refer to this image or else visit a mechanic. If the problem persists, please raise a complaint ticket and with explanatory pictures / videos.
