Trek Domane Gen 5 returns to basics, trimming 305 g by dropping IsoSpeed
Trek’s Domane Gen 5 trims about 305 g by dropping IsoSpeed and in-frame storage, relying on a revised carbon layup, a round seatpost, and 40 mm tyre clearance to preserve comfort. The lighter frame and fork enable six sizes and builds from 900 Series to 500 Series, with top models around 6.63 kg, a 20 mm rise cockpit for a more upright endurance ride, and no in-frame storage but extra bag mounts; 35 mm tyres are supported, balancing aero and rolling resistance. Pricing spans the range from entry SL to high-end SLR models as Trek positions it as a lighter, more affordable all-road carbon option.
