In total, Trek say they’ve shaved off 300 g compared to the predecessor, which would be a significant weight reduction. The SLR 9 with the eTap groupset weighs in at just 7.36 kg in size 56, making the 2023 Madone SLR Disc the lightest Madone Disc on the market. Weight optimization – How much lighter is the 2023 Trek Madone SLR 9 eTap Gen 7?Īs the predecessor, the 2023 Trek Madone SLR is made of OCLV 800, which is the highest grade carbon that Trek offer. All these figures are relative to the 6th generation Trek Madone. The optimised rider position alone should save around 10 W, giving you total saving of 19 Watts at 45 km/h in the drops. the new IsoFlow system, improved tube shapes and cockpit design (without the rider). Accordingly, the American brand claim to save 9.3 Watts with the bike’s improved aerodynamics, i.e. Trek have attempted to quantify the promised gains. The enlarged bottom bracket area is claimed to optimise the bike’s aerodynamics Even the water bottles and the front mech have been integrated into the frame design, and the enlarged bottom bracket area takes advantage of the latest UCI regulations to further improve aerodynamics, like on the new Cérvelo S5 or SCOTT Foil RC. The slightly flared drops should offer improved control over the bike while also optimising the airflow over the rider’s thighs in order to reduce drag. A narrow handlebar for better aerodynamics with flared drops to retain control: the new cockpit claims to offer improved aerodynamics by putting the rider in the optimal position and channelling the airflow over the rider’s thighs as smoothly as possible. As such, the handlebar of the Madone has been designed specifically for this bike, bringing the rider into an aerodynamically optimised position. So, there are a lot of gains to be made by optimising the position of the rider. After all, the rider produces the most wind resistance by far: riding on flat terrain, as much as 75% of the total drag is caused by the wind resistance of the rider, from speeds of just 15 km/h. It’s not just thanks to the new IsoFlow system that the aerodynamics of the 2023 Trek Madone SLR Disc have been improved, but also via the cockpit and therefore the position of the rider. Improved aerodynamics of the 2023 Trek Madone SLR 9 eTap Gen 7 Increased, weighing around 300 g more than the IsoFlow No, it changes depending on the extension of the seat post Yes, can be adjusted according to the rider weight Trek IsoSpeed vs IsoFlow – An overview of the differences Trekĭamping element, seat post decoupled from the seat tubeīetween the seat stays, seat tube, and top tube The new IsoFlow system on the Madone SLR consists of trapeze shaped cut-out in the seat tube where it would usually meet seat stays and top tube. Besides the striking IsoFlow design, Trek obviously spec the bike with high-end components, including some from their in-house brand Bontrager, and offer deep customisation via the Project One configurator. Trek have completely overhauled the existing IsoSpeed damping system, implemented several aero optimisations such as bigger aerodynamic compensation surfaces, according to the latest UCI regulations, and reduced the weight significantly. The American brand promise a wide range of advantages and claim to have solved some of the issues of its predecessor. The 2023 Trek Madone SLR Disc is more than just a looker with its radical design and all-new IsoFlow system. The reactions ran the gamut from “that’s definitely a mad one” all the way to “at first I thought it was a joke, sadly it wasn’t.” There was a lot of speculation, but now we’ve finally got the first in-depth test results. When the first photos of the 2023 Trek Madone SLR at the Critérium du Dauphiné went live, the online community went nuts. Trek claim to have developed their fastest bike yet with the all-new 2023 Madone SLR, and caused an uproar in the community while they were at it.
