Trek Domane SL 7 Disc Road Bike Gen 4 2023
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.
Ultegra Di2 R8100 is Shimano’s second-tier electronic groupset that offers high-performance shifting and impressive braking. Light lever presses actuate the crisp shifts effortlessly, no matter whether climbing uphill or sprinting full gas, and the combination of a 12-speed, 11-34 tooth cassette and 50/34 chainset ensure that either scenario is well catered for in terms of ratios. The system can communicate via Bluetooth with smartphones and GPS devices for access to extra information and customisation of certain functions.
The Bontrager R3 tyres and OCLV Carbon Aeolus Pro 37 wheels are both tubeless-ready so can be run at lower pressures for fewer punctures, more comfort and lower rolling resistance. At 37mm deep, the rims are deep enough to confer an aero advantage at speed but not so deep as to be troubled by crosswinds, and light enough that they excel when the road turns upwards, making them an ideal match to the versatile frame.
