Summary
Trek’s fifth-generation Domane replaces its long-running IsoSpeed comfort system with a simpler carbon frame, a new 27.2mm flex seatpost and stock 35mm tires, with clearance growing to 40mm.
SLR framesets are 305 grams lighter than the prior generation, and Trek says the new bike still comes within 5% of the old model’s vibration-damping performance while boosting pedaling stiffness by 6%.
The carbon Domane SL starts at $2,399.99, the range tops out at $11,499, and a 50th-anniversary Project One edition costs $14,999; Trek claims 6.63kg for the SLR 9 SRAM 1x build.
Trek said bigger-volume tires opened the way to a lighter, less complex endurance bike, and added that existing IsoSpeed-equipped models will continue to be serviced.
