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 extension of Hope 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 40 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 with a long cage is to be recommended.
