Variant Shimano ZEE RD-M640 Freeride prehadzovačka, 10-kolo, krátke ramienko (SS)

I was looking for a derailleur with a short arm on the market (so that there is as little possibility of catching on the terrain), I found it, but they did not have a capacity of up to 34/36 teeth on the cassette. So, in the end, the only option was to buy this one
And I'm not kidding it fits my heel exactly, the chain is stretched really hard, so it doesn't swing, even with the smallest cog.
I can't adequately assess the mode switching, because I don't follow her behavior with my eyes at speed. But even on OFF the chain is cracked.
We will see in time how the wheels will last, but for now the maximum satisfaction is if it is used with Shimano ZEE SLM640 shifting

I have it with the ZEE SL-M640 lever, maximum satisfaction, I also have a tensioner and in this combination the chain does not even move. When I didn't have a tensioner yet, a friend bought one and my chain was tighter than his with a tensioner

I've driven a derailleur with an 11-36z cassette and a single derailleur with no problems. The tension of the spring on the derailleur can already be felt by the sound of the chain. I used the downhill system. I recommend.

I am satisfied, it shifts in a moment, stretches the chain perfectly - no tensioner is needed. The only thing I can criticize is the durability - after about 1000 km, the pulleys are visibly worn.

Variant Shimano ZEE RD-M640 Freeride prehadzovačka, 10-kolo, krátke ramienko (SS)

Good day. I want to go from a 3x8 to a 3x10 system. The triple gear has 24, 34 and 42 teeth. I also have a chain, otherwise I don't understand what the difference is between an 8sp 116 link chain and a 10sp chain also 116 links.. Will it fit me with the 8sp chain, or do I have to buy a 10sp chain as well? Will it also fit on the converter? Thanks for the answers

SK Dobrý deň, reťaz sedieť nebude pretože jedna je buď užšia alebo širšia v článkoch, ďalej prevodník sedieť nemusí pretože môže byť vyťahaný a prispôsobený k predošlej reťazi. Celkovo toto nieje prehadzovač určený na 3x10 systém. Odporúčam poriadne prečítať popisy a nájsť s dlhším ramienkom.

SK Dobrý deň,

Potrebné by bolo zmeniť radenie za 10 rýchlostné Shimano, kazetu za 10 rýchlostnú v rozmedzi 11-32 - 11-36 z. a reťaz za 10 rýchlostnú. Čo sa týka aktuálneho prevodníka tak tam by asi záležalo ako by s ním fungovala 10 rýchlostná reťaz.

SK Dobrý deň,

FR a DH verzia majú odlišný B-link - diel, ktorým sa pripája prehadzovačka k pätke bicykla. Pri DH verzii je o niečo kratší, čo zaručuje teoreticky vyššiu istotu presného a rýchleho radenia, približuje prehadzovačku o niečo bližšie ku kazete, zväčšuje tak ground clearence, ale teda trochu znižuje možnú kapacitu počtu zubov na pastorkoch kazety (max. pastorok 28 z. vs. 32 z. pri FR verzii).
