Love the finish and hub
Bought this set a few months ago, and FINALLY got out on the trails yesterday for my bikes maiden voyage! I love how snappy my bike feels. They seem to be perfect for my riding style overall. Wider wheel so went with a 2.5 and love the feel. The Hydra hubs are amazing as well. Riding some skinny lines and logs, the extra engagement really gives you more control! Overall, I'm glad I went with these i9's.
Wheels arrived in great shape. They were both true and easy to set up tubeless. I was able to get them seated with a floor pump. No compressor needed.
... But still in the box. Waiting on some other parts before I dive into my build. I'll update this as soon as I try them out. I do know that the hub has a crazy crazy engagement! Looking forward to abusing them!
