Can non-Shimano cassettes, such as the Sunshine 11-42T, be extended to 50T using a cassette extender such as:Garbaruk Xtender for Shimano XT 11-speed Cassettes, or, the OneUp Xtender for Shimano XT 11-speed?


What is the reason they would only be compatible with Shimano cassettes? The Sunshine 11-42T has the same-tooth cogs as the Shimano 11-42T cassette, namely 11-13-15-17-19-21-24-28-32-36-42. So why then can Shimano XT cassettes only be extended using cassette extension products?
