Giant P-TRX 1 MTB wheels review£799.98

Solid but pricey wheelset

BikeRadar score2.5/5

We’ve ridden these wheels a lot on Giant bikes this year and they’re decent performers. The deep-hooked rims means actual tyre stance isn’t that wide, so bigger tyres can feel bulbous. But with mid-width tyres, the P-TRX 1s corner precisely. The rims hold on to tyres well at low pressures if you convert them to tubeless with the supplied tape.

The straight-pull DT Swiss bladed spokes are tight and even, with no loosening during testing despite low flanges leaving a long unsupported length. Wheel weight is low too, and the freehub picks up fast and spins silently, which stealth fans will love.

The price seems seriously steep though, especially as you’ll have to source 142x12mm axle converters separately from DT Swiss as Giant “can’t supply them”.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
