Great but no valves
4/5 Does not come with valves installed. Under “features” it states that come taped and valved, but that is falsely advertised. Expect to buy valves.
Fantastic Wheel / nice upgrade over stock
Needed to replace my previous stock rear wheel on a 2018 Scott Scale 710 plus. Initially had an 27.5" w/ an XD hub and Ordered an XD hub specific wheel. Ended up receiving an 'XDr' Hub, which worked perfectly with my SRAM Eagle cassette, as they included the necessary 1.85mm spacer. Be careful when removing the plastic protector rings from each side of the wheel's axle housing. They are pressed onto the axle housing 'end caps', which you may need to pull out of the plastic protection pieces (used for shipping). Performance wise I love the wheel. Definitely far more engagement points over most stock wheels on lower - mid tier bikes, and makes the bike feel 'better' than new. I will definitely be purchasing the matching front wheel. Great upgrade for a new bike with inexpensive wheels, or freshening up an older mountain bike.
