Meanwhile, there are various manufacturers of cartridge enhancements that make your 11-36er 10-speed cassette a 11-40 or even 11-42 cassette. The problem is that the derailleurs are not designed for it. The upper Leitröllchen must be positioned very far down, so that it comes below the 40er or 42er pinion. If the chain but then on the 11er pinion of the cassette, the distance between the pinion and the idler pulley is very large, so that the switching performance suffers. Garbaruk from Ukraine here offers the perfect solution. The special cage plate positioned the Leitröllchen in the optimum position, so that the sheave can work perfectly still and the switching performance does not suffer.
INFO: you can continue to use your existing gear change rollers.
