Description:

2023 TREK MADONE SLR9 GEN7 P1 58CM SRAM RED eTAP BRAND NEW READY TO SHIPThe American brand called it IsoFlow, removing the previous compliance-improving IsoSpeed system entirely, with the intention of improving aerodynamics and saving a little weight.Meanwhile, the rest of the Madone saw an aero overhaul – there’s a straighter top tube, deeper profiles around the head tube and bottom bracket to fill the UCI’s so-called ‘compensation zones’, plus a remodelled integrated bar-stem that’s said to help the rider improve their aerodynamics.It all sounds pretty enticing to a racer or a speed-obsessed sportive challenger, and the Madone has proven to be a bike worthy of its place at the top table of aero-optimised race machines.A couple of curiosities aside – issues that you could argue should be remedied in a bike whose asking price is well in excess of £10,000 – it’s a pro-level bike in every respect.The Madone has been Trek’s foremost race bike for many years. First seeing Tour de France action in the early 2000s, it started life as a lightweight climbing machine, before transitioning into an aero bike in 2015.That aero overhaul also took many of the lessons learned from Trek’s comfort-oriented race bike, the Domane, and the lightweight Emonda, with the brand integrating its IsoSpeed technology in the top tube / seatstay junction in one of the most aggressively distinctive aero race bikes in the pro peloton.But that design had its drawbacks. Although retained for a 2020 refresh of the Madone platform, the IsoSpeed decouplers were seen as unnecessarily complicated compared to other, simpler competitor tech (alongside the rise of road disc brakes and the increased tyre clearance they offer), while it added weight, too.In fact, Trek said pro race mechanics would often simply set the decouplers to the stiffest setting for their riders, and leave it there.So, with the unoriginal brief to make the Madone “lighter and faster, as always”, and bearing in mind the years of pro rider and mechanic feedback, the bike has seen an overhaul that waves goodbye to IsoSpeed and welcomes IsoFlow, which is said to improve aero performance and save some of the weight IsoSpeed was adding.The result is that with a rider atop it, the new Trek Madone is claimed to be 19 watts more efficient at 45kph.According to Trek, that can save you 60 seconds over what would have previously been an hour’s ride, and you’ll still save 59 seconds at 35kph, and 58 seconds at 25kph.Not all of that can be attributed to the IsoFlow system, though. The frame tubing has seen a refresh of its Kammtail-inspired design.Gone is much of the curvature of the top tube, for instance, and the UCI’s compensation zones – the zones in which each UCI-regulated maximal tube cross-section intersects – have been filled in somewhat, in a trend we’ve seen across a few of the latest aero bike releases, including the new Scott Foil RC and Cervélo S5.The new aero bars are also claimed to account for half of the aero and weight savings alone, enabling the rider to more naturally and comfortably access a more optimised riding position, thanks in part to the narrower hood position.The new integration shaves 150g from the overall weight of the bike, with the other 150g being dropped from the rest of the frame.The frame itself is crafted using Trek’s top-of-the-line 800 Series OCLV carbon, which you get on any specification of the new seventh-generation Madone SLR.In the size large (56cm) on test, the Madone SLR 9 eTap tips the scales at 7.29kg – that’s without any dressings, including pedals, bottle cages and the out-front Bontrager Blendr head unit mount (which wasn’t available at the time of the test, but which every purchaser will receive with their Madone).Compared to other top-spec aero road bikes, that’s just shy of Scott’s 7.22kg claimed weight for its Foil RC Ultimate, and is likely to be comparable with Cervelo’s S5, which Simon von Bromley has tested at 8.2kg dressed in SRAM Force eTap.
