Industry Nine gave the Grade300 a complete face lift. They stretched the rim to a 30mm inner width while adding material to the bead wall for increased durability. All while not adding any extra weight. This new rim, combined with their System spoke and Hydra hub chassis makes for one incredibly strong wheelset weighing in at 1880g. This wheelset is stout enough for park laps but still light enough for race day. Rounding out the new look are their new and improved rim graphics. The stiffer spokes provide unrivaled cornering and tracking performance through the nastiest terrain -No more wheel flex throwing you off line. The added stiffness also makes tuning easier; eliminating the mushy, vague feeling most DH wheels deliver allows you to accurately judge everything from tire pressure to suspension settings. Throw in DH-specific spokes, and lace it to one of the lightest, strongest, and widest DH rims out there and you've got the ultimate DH wheelset.
Industry Nine set out to create the most durable high engagement hub system possible. The result was their new Hydra rear hub which boasts an astonishing 690 points on engagement. The hub features 6 pawls that work in 6 phases, this means that all the pawls, and the teeth on them, catch the teeth on the drive ring individually instead of simultaneously. In other words, every time the drive ring moves to the next tooth, you will hear six individual clicks. This new-to-the-industry design limits and minimizes the wear and tear on the system and provides a more consistent ride. The hubs also feature a new stiffer axle system with larger bearings increasing the hubs overall longevity.

AZ riding beat up my stock wheels. Consequently, I needed to get something better. I did my research and the Grade 300 Hydra Wheels were what I decided on. I am 5' 10" tall, weigh 200 lbs and the 300 lbs weight limit on the wheels is nice! I have been riding them for about 4 weeks now and am very happy with my decision. I noticed right away that they rolled a lot better than my stock wheels and that they can handle the riding that I do, which is mostly in the Phoenix/Metro area...technical and rocky. They have taken some big hits and not a scratch. Lastly, they get a lot of compliments out on the trail, too. People like the looks and the way the Hydra hub sounds.
