Variant Shimano XT RD-M781 prehadzovačka, 10-kolo, super dlhé ramienko (SGS), Shadow RD, strieborná

SK Vymenil som prehadzovačku, pretože sa mi ulomilo ramienko, ktoré bolo v tom čase nedostupné(dlhá doba čakania) a ja som chcel bicyklovať pretože bolo fajn počasie. Prehadzovačka funguje výborne a už si dávam pozor na ramienka pri opieraní bicykla aby som nepoškodil ramienka prehadzovačky.

Variant Shimano XT RD-M781 prehadzovačka, 10-kolo, super dlhé ramienko (SGS), Shadow RD, čierna

It's currently serving as a backup, but I've had it installed and ridden it for 7 years on a full-speed, 3x10 gears. What might help someone is that it handles a 42-tooth cassette without any problems. Otherwise, it's a very high-quality derailleur, there's nothing to criticize about the XT line at all.

áno, prehadzovačka pôvodne nie je určená na 42 zubovú kazetu. Viacerí užívatelia, ju však bez problémov používajú aj na 42 zubových kazetách.

I confirm that according to the parameters found, XT derailleurs are ideal for 11 to 12-wheel cassettes, and this one is only intended for a 10-wheel cassette with up to 36 teeth. It is expressly written there max. 36T.
For a 1x10 system, e.g. the Deore CS-M4100-10 cassette with pinions 11-42 or 11-46 is only suitable:

Can this derailleur replace the Shimano DEORE LX RD-T670?
It is a trek 3x10 speed, pinions 11/34.
Shift Shimano Deore SLT610-10sp.
You can also recommend a lower board, the important thing is that it is completely compatible so that I can easily manage the exchange.
Well thank you.
