Bought for a bike from the 90s used mainly for commuting. For little money, enough music - at least that's how I would phrase it, I didn't want to put the old derailleur back together anymore so I solved it like this and I'm satisfied. After a good adjustment it shifts like a 12s deore Just be careful with the attachment, it is attached with a small screw and a plate and the axle fits into the cutout on the frame and on the derailleur (you have to take the wheel off) and the wheel is tightened and that's it.. But I had a bit of a fight with it ? because the frame was already crooked and the old attachment was getting in the way.. I bent it to the side

A simple, reliable, easy-to-adjust derailleur, suitable for less demanding riders who don't need a huge gear range. Combined with a Shimano multi-wheel/cassette, it will last for years.

SK Dobrý deň,

žiaľ takúto kombináciu pri tomto počte prevodov nemáme vyskúšanú, môžete prípadne napísať do nášho fóra - https://www.mtbiker.sk/forum/komponenty/prechod-z-3-x-10-na-1-x-10-t32825.html . Jedná sa o SGS prevedenie, takže predpokladáme, že by mala postačovať. Rozdiel medzi modelmi je v tom, že TY500 je vyšší model, zrejme bude o niečo ľahší, no funkčne sú na tom prehadzovačky parametrovo rovnako.
