For this latest Gen 7 version of the Madone, Trek’s aero bike, the US brand removed the IsoSpeed Decoupler of the previous Gen 6 model and left, in its place, a big hole.
OK, it’s not the crude, reductionist approach it sounds like. The old bike’s suspension system at the top tube/seat tube juncture added weight and was mostly redundant since Trek discovered most riders would ‘set and forget’.
And by radically reengineering the frame Trek claims to have saved 300g, and says the new bike is almost 20 watts faster than its predecessor, which equates to 60 seconds per hour when ridden at 45kph. It looks radical, too – always a good thing for a new bike.
