Sunrace RD-R81 Rear Derailleur 8sp Mid Engineered Polymer & Steel Construction

Perfect replacement and or upgrade for casual riders. Works perfect. Looks great. Built very strong.;

If installed by a qualified mechanic its just as good as Shimano or SRAM. Its not the top end of the line so don't compare it to the most expensive product. I find it sturdy and smooth. Zero Issues on two different bicycles.;

Could never get the shifting dialed in. Shimano dérailleurs are definitely better.;

very goo derailleur for the $. Shifts Solid and easy to tune. Also seems to be built for more abuse than comparable shimano derailleur (Sora/Claris).;

I replaced every part of a Haro v2 except frame and Rockshox. Sunrace products go on sale sometimes where you cant lose. I used Sunrace 12-25 rear cassette. Wanted to use a short cage but backed out but think I got one anyway. I replaced a old alivio and the Sunrace quality and materials seems as good or better. Shifting is quick and it holds adjustment well. Thebtwo Sunrace products I use are most
definately better than "old" Shimano. If keep an eye out can get them for under $10 each. Add something and use free shipping and you will be satsfied.;
