I bought this for my Son's bike to do some Christmas upgrades. He is riding an older bike of mine that was 3x9, then single speed, now 1x11. It was nice that almost everything needed is in the box. I did purchase a chainring separately. I was on a Christmas time crunch, but looking back I would have price shopped a bit more, as it seems most online bike stores would be cheaper for all SLX parts. But a lot of bike e-tailers are out of certain parts, and this was ready to go kit. I will say that we got an Oval 32 chainring which is probably a bit small for 26 wheels and his majority road riding. We will probably purchase a 36 front to get a little more out of the back range. Also, we did not know to use an extender that 1 reviewer mentioned. I need to do more research on this for older 26 bikes. It does seem to work, but not sure if it is optimal without the extender.

I will be buying another of these kits. Installed without issue and took very little adjustment to dial it in. Shifts well under power. I have zero complaints with this groupset.

Excellent product and quick shipping
