I was not aware that it is possible to convert Shimano cable ratio to SRAM or the other way around. Fortunately, after buying the Aceoffix D10 trifold bike and being very disappointed with SRAM-compatible components, I discovered there is a way to mix the components. I was able to install the Alivio shifter steering the original derailleur. It is the dream now. For this case, I used Jtek Shiftmate 6. Maybe a good hint for another one . If it is true that they are out of business now, the stock will not last long. I bought mine in Germany
