The mountain bike website NSMB published a “First Impressions” review of the new Giant TRX WheelSystem, detailing the features and technologies in the composite trail-riding wheels and describing initial riding experiences on the TRX 0 in a 27.5 wheel size.
“Giant employs some interesting tech in the wheels,” wrote tester Tim Coleman. “One of those is Dynamic Balanced Lacing (DBL). Giant uses different spoke tension on the same side of the wheel for the “pushed” and “pulled” spokes. The idea here is to allow for optimized spoke tension when the wheel is actually in use, and not when it’s bouncing around in the back of your Tacoma.”
Coleman also described the new carbon rim profile: “The new rim is made in their factory in Taiwan and the rim profile is common to both the 27.5 and 29 inch diameter rims… 30mm internal width, thicker rim beads, and hookless design. I like the increase in material on the rim bead to not only increase strength, but to also increase the impact area of the tire to reduce the chance of pinch flatting. Somehow Giant managed to pull weight out of the existing TRX carbon rimes, while making them more durable. Rim weight is 480 grams for the 27.5 and 490 grams for the 29er.”
As far as the ride quality, Coleman wrote: “I've done a number of rides on the wheels so far including two races. In both cases I was really happy with my riding and placed well. I also absolutely bludgeoned the rear rim into some rocks (not on purpose, but we all get a bit wild once in a while) with no flat or rim damage to report so far.”
