Long Term Review
Giant TRX0 Wheelset Reviewed
I published my first look on the Giant TRX0 wheelset here in May of this year. Since then I've been riding and racing on the TRX0 wheelset. I've done 700 hard kilometers on the wheels, enough to share fully flushed out impressions.
Mounting up my favourite Schwalbe, Maxxis and WTB tires was fairly easy. Some tire levers were required, but I could inflate each with a simple floor pump. As far as rim protection goes, the test was conducted without tire inserts. Fit and finish of the hubs is excellent, as to be expected from DT Swiss.
The wheels came stock with DT Swiss' 18-point engagement star ratchets. Having come off a high engagement hub, it took some time getting used to the 18 points. Once I was rolling it rarely made a difference, but on occasion I found myself wishing for faster response. I was able to track down a 36 point engagement star ratchet set, which took a matter of minutes to install and I rarely found myself wishing for more. DT Swiss offers a 54 tooth ratchet upgrade kit if fast as possible is your preference.
In terms of feel on the trail, these Giant TRX0 wheels feel very similar to the We Are One Agents I was on most recently. I noticed the lower rotational weight with the Giants however, and this difference is almost entirely in the spokes being used on the Giant wheels. The TRX0 wheels are snappy when accelerating and for my riding and aggression level I really liked the level of stiffness. Stiff enough that the wheels never felt vague, but not so stiff that they felt harsh or jarring. I'm not sure if it's the high spoke tension, but the Giant TRX0 wheels always felt very precise to me. The wheels always seemed to be tracking in exactly the spot and angle I placed them.
In this year's local racing series (the NSMBA Fiver World Series) we raced some of the roughest trails around. In one race I clipped one tree and rode full speed directly into another. The front tire took the brunt of the impact, which then twisted and bent the fork . The impact was violent, and the force to bend the fork passed directly through the wheel, which was shockingly unaffected. The wheels went on to survive another particularly harsh test; being raced down Ned's Atomic Dustbin. This trail is a fast sinuous ribbon of wheel-destroying rocks. Unless you walk your bike down you are going to smash your wheels into something hard. I raced with reckless abandon, smashed some stuff, and wound up winning the race. A post race inspection showed the TRX0 wheels were no worse for wear, without any tire inserts.
While smashing some cutties one of the spokes in the rear wheel finally cried Uncle and snapped. Strangely the spoke broke near where it crosses another spoke, and not at the ends where you'd normally expect. At first it looked like abrasion between the spokes was the culprit. However none of the other spokes showed any signs of abrasion. The spoke was on the none drive side, which eliminates chain damage. It looks like a crash or shuttle rash damaged the spoke enough that it later failed in fatigue. Luckily these spokes are fairly easy to replace. Ultimately I'm impressed with the strength and durability of the Giant TRX wheels."
I'll be the first to admit that I was skeptical of Giant's latest line of carbon mountain bike wheels. However the Giant TRX0 wheels proved excellent performers on the trail, and impressed with their durability. Coming in at 1588 grams for the set they were surprisingly precise and durable. They're not cheap at 2,100 CAD/2000 USD, but you are getting an excellent wheelset for that price. If that price is too steep, Giant offers a sister wheelset, the TRX1, for 1,300 CAD/ 1182 USD. The TRX1 uses the same rim as the tested TRX0, but with cheaper hubs and spokes. The Giant TRX0 seems to be a well thought out, and well executed wheelset and proved to be a top performer on the trails while exceeding my expectations.
