Review on 🚲 Ultimate MTB Groupset: JGbike Compatible with Shimano M8000, M7000, M5100, 11-Speed Shifters & Rear Derailleur, KMC X11 Chain, Sunrace 11-46T/11-50T Cassettes by David Jennings

I bought this for my son's bike to do some Christmas updates. He rides my old bike that was 3x9, then single speed, now 1x11. I was glad that almost everything you need is in the box. I bought the chain separately. I had a crunch over Christmas but in hindsight I would have bought a bit more as it seems like most online bike shops sell all SLX parts for less. But many online bike shops don't have certain parts, and this kit came right out of the box. I will say we have a 32 oval chainring which is probably a bit small for 26 wheels and most road riding. We will probably buy a 36 in the front to get a little more out of the rear. Also, we didn't know if we should use the extension cord mentioned by one reviewer. I'll have to investigate this further for old 26 bikes. It seems to work, but I'm not sure if it's optimal without an extension cord.
