Amazing rear wheel for XC
This wheel is a huge upgrade over my stock wheel. The i9 hub is buttery smooth and the engagement is instant. It's stiff but not harsh. My speed on the trails has definitely improved. The price was a steal.

Great wheel, but the loud hub is not for everyone
Performance is top notch: light, stiff, and fast. The i9 hub sounds like a swarm of angry bees, which is cool to some but annoying to others. I personally like it, but my buddies complain when I'm behind them. Otherwise, it's a fantastic wheel.

Perfect XC upgrade
I've been riding this wheel for a few weeks now and it's night and day compared to my old wheels. The acceleration is immediate and it holds speed well. It's also held up to some rough sections. Highly recommended.

Dented the rim on a small rock
I'm a lighter rider (150 lbs) and I hit a small rock on the trail and the rim has a noticeable dent. I've had cheaper rims that took harder hits without damage. Maybe I got a bad one, but I'm not impressed with the durability.

Reliable and fast
I've put over 200 miles on this wheel, including some muddy races, and it's been flawless. The i9 hub is excellent and easy to service. The rim is true and stiff. The only reason for 4 stars is the weight could be a bit lower, but for the price, it's fine.

Great wheel for the price
You won't find a better rear wheel with an i9 hub at this price point. It's light, stiff, and the hub is incredibly loud and fast. I've ridden it in rough terrain and it's been rock solid. I'm very happy.

Feels expensive
This wheel feels like it should cost triple. The hub is buttery, the rim is strong, and it looks sharp. I've already ordered the front wheel to match. Do it.

Good wheel, but check the spoke tension
The wheel is good, but the spokes were a bit loose out of the box. I had to tension them after a few rides. Once I did, it's been great. Not a big deal, but something to watch.

Not as light as I hoped
I bought this for my XC bike expecting a significant weight savings, but it's only slightly lighter than my old wheel. The hub is awesome though. If you're looking for a performance upgrade, this is it, but don't expect a super lightweight wheel.
