Frequently asked questions
Trek ’s road bike range has been based on two main models since 2024: the Madone (aero/racing, which has also replaced the Emonda since 2024) and the Domane (endurance/comfort). The Emonda, which was the lightweight, climbing-oriented model, was discontinued with the launch of the Madone Gen 8: Trek believes that this new Madone is as light as an Emonda whilst being more aerodynamic. The Madone Gen 8 uses OCLV 900 SLR series carbon. The Domane stands out thanks to its rear IsoSpeed, tyres up to 38 mm wide and a more upright endurance geometry. The three models – Madone, Domane and Emonda – form anagrams of one another, a hallmark of the brand.
OCLV (Optimum Compaction Low Void) is Trek ’s patented carbon manufacturing process, which reduces micro-air bubbles in the composite to achieve greater stiffness for the same weight. The OCLV 500 series is used in the SL models (mid-range), the OCLV 800 series in the previous SLR models, and the new OCLV 900 series in the 8th-generation Madone. The OCLV 900 incorporates 20 per cent stronger fibres, allowing for less material to be used and thus making the frame even lighter. This technology is developed at the ‘ Trek ’ factory in Waterloo (Wisconsin, USA).
Yes, IsoSpeed is a mechanical decoupling system between the seat tube and the rest of the frame that allows for independent vertical flex. On the Domane, front and rear IsoSpeed significantly reduces vibrations transmitted to the hands and buttocks on rough tarmac. On the 8th-generation Madone, IsoFlow technology (a cavity beneath the seat tube) provides 80 per cent more vertical compliance. This makes the Domane the most comfortable ‘ Trek ’ road bike, comparable to the Specialized Roubaix on challenging sections.
Yes, Trek Bicycle Corporation was founded in 1976 in Waterloo (Wisconsin, USA) by Dick Burke and Bevil Hogg. The brand started out with silver-brazed steel frames before switching to carbon. Trek owns or distributes the following brands Bontrager (components/accessories), Electra (lifestyle bikes) and Diamant (German bikes). The high-end carbon frames are manufactured in the USA; the mid-range models are assembled in Asia under the supervision of Trek.
Project One is Trek ’s customisation service: you choose the colour, components and size of your bike using the online configurator. Available on the Madone, Emonda, Domane and Checkpoint gravel ranges. Over 500 colour combinations are possible, depending on the model. The bike is built to order in the workshops at Trek; the lead time is usually 4 to 6 weeks. Project One prices are approximately 10–15 per cent higher than those of stock builds.
Trek Uses the H1 (aggressive/competition) and H2 (comfort/endurance) systems to adapt the geometry to different levels. The size Trek corresponds to the seat tube length: 47, 50, 52, 54, 56, 58, 60, 62 cm. The online size guide Trek matches height and inside leg measurement to recommend the optimal size and geometry. A posture assessment at a retailer Trek is recommended for high-end bikes.
Yes, the Checkpoin Trek is the gravel bike in the range, available in carbon (SLR, SL) and aluminium (AL). It accommodates tyres up to 45 mm and features mounts for pannier racks, mudguards and additional water bottles. The Checkpoint is available with either Shimano GRX or SRAM XPLR groupsets, depending on the configuration. For long-distance bikepacking, it is compatible with all standard panniers on the market.
Yes: recent Trek frames use universal standards (12x100/142 mm thru-axle, Centre Lock or 6-bolt disc brakes). Compatibility with DT Swiss, Zipp, Fulcrum or other wheels is complete on recent disc-brake models. Aeolus Bontrager s are supplied with standard fittings, but switching to other brands is no problem. On older rim brake models, the 9 mm QR standard is used.
For the Madone SLR (top-of-the-range), Shimano Dura-Ace Di2 12-speed and SRAM Red AXS are the standard configurations. The Madone SL (mid-range) is available with Shimano Ultegra Di2 12-speed, offering excellent value for money. Mechanical groupsets are available on the Madone SL 5 with Shimano 105 12v for those on a tighter budget. The Di2 or AXS electronic groupset is highly recommended to take full advantage of the TiCR internal cable routing.
Yes, the Allant+ and Domane+ ranges cover road and city e-bikes. The Domane+ LT is Trek ’s electric road bike, featuring a discreet ‘ Fazua ’ motor integrated into the down tube. Its appearance is very similar to that of a conventional road bike and its weight is kept to around 12 kg. For long distances with elevation gain, it’s an excellent option for cyclists who want to explore without exhausting themselves.
