The optimal solution for users of Shimano 10-speed cassettes, which when driving up steep inclines with 1x10 drives, often lack an even larger sprocket.
The cassette expansion of e * thirteen is very easy to install, it fits behind the usual 11-36 cassette, but displaced due to the predetermined width of the free wheel, a pinion.
The 17er pinion and a spacer made of the existing cartridge is removed and then the 42 teeth pinion completes the remainder of the cassette.
For operation with a 1x10 system, please use a derailleur with medium length cage. When using 2x10 drives a switching mechanism is advisable with long cage.
