Trek Domane SL 6 Disc Road Bike Gen 4 2023
With an aerodynamic yet comfortable frame and electronic shifting, Trek’s Trek Domane SL 6 Disc Road Bike Gen 4 offers good value for money who want a bike that can tackle everything from long, fast-paced rides to back lane exploring and everything in between.
The frame is made from Trek’s 500 Series OCLV Carbon that balances weight, stiffness and strength whilst also featuring their IsoSpeed technology for a much smoother ride. IsoSpeed allows the rider to be better isolated from small bumps, irregularities and vibrations from the road surface for less fatigue and more speed without reducing the efficiency of the power transfer. Clearance for tyres up to 38mm wide means that there are plenty of opportunities to explore less well-travelled lanes and trails in comfort and there are top tube mounts for a bag and an internal storage compartment in the downtube that provide ample room for nutrition, spares and tools.
Updated Kammtail tube shapes ensure that the frame is aerodynamic at speed without any undue weight being added and the design is Trek’s 1.5, endurance-biased geometry that allows for a fast, efficient position which is also comfortable enough for long sportives and even multi-day trips. The very handy addition of hidden mudguard mounts also means that this bike could even be used as a year-round option for riders who don’t want to forgo speed and performance when training in the wetter months.
Bontrager’s Paradigm Comp 25 wheels are specifically designed to work with wider style road tyres such as those on the Domane, as the 25mm inner width provides good stability and support for them. They are tubeless-ready, allowing the tyres to be run at lower pressures for less rolling resistance, fewer punctures and more comfort.
Shimano’s evergreen 105 groupset has now received the Di2 treatment, and so offers effortless electronic shifting at a reasonable price. The wide range of gears is ideal for the bike’s broad brief, with a 1:1 climbing gear available for the hardest hills and an 11t sprocket for high-speed descents. Connecting the system to Shimano’s E-Tube app enables some personalisation of functions to be programmed and gives access to other ride metrics and interesting data.
