Argon18 sum pro

At road. Our reviewers are experienced cyclists that we trust to be objective.

What is in a name? Bike names are normally abstract, words that sound cool. A Sum, by contrast, sounds rather utilitarian. Mathematicians may disagree, but I have never thought of a sum as cool. Maths does however have a wonderful logic and precision. Having been one of the first people to ride the new Argon 18 Sum Pro , I now understand the name.

Unlike many of its competitors, which have almost unanimously gone down the proprietary or one-piece bar-stem setup route, the bike sticks to a traditional non-integrated cockpit. This makes customising the Sum Pro easier — good for fettlers with exacting requirements — while the short stack naturally positions the bike towards the aggressive end of racy bike fits. Argon 18 says the frame features truncated aerofoil tubing throughout, with an optimised down tube said to help shape airflow around a water bottle. Up front, the fork uses bladed legs with plentiful clearance around the front wheel and tyre, and an hourglass-shaped head tube, which fits a 1. The frame fits a BB86 press-fit bottom bracket. I had my size-medium test bike set to the middle of the three settings 15mm , providing a stack of mm and reach of mm. This might not sound much, but the steering feels quite relaxed as a result. More on that to come. The In my case, knowing where my optimal sitting position should be in relation to the bottom bracket, I was able to fit the saddle in the middle of the 20mm setback range offered by the seatpost as opposed to pulling the saddle forwards. At the time of writing, the bike continues to be sold with this previous-generation drivetrain as opposed to the latest Force AXS groupset.

You want more than that. Meet the best of the best: aero to match the Nitrogen, pure road performance to match the Gallium Pro, with race-ready handling and premium ride quality. The all-new Sum Pro features our most advanced layup and technologies to get you to the front of the group and keep you there, through the climbs, the corners, and the sprints. For our newest generation of bikes, we wanted to push our 3D System even further by merging it seamlessly with the frame. Our road race geometry is designed around the razor-sharp reflexes and precision handling required for racers of all levels. To achieve the optimal balance of comfort and performance for our endurance line, we needed geometry uniquely aligned with the demands of long-distance riding and racing. In conjunction with the best geometry, we also needed to optimise frame topology and carbon layup.

Own the season: the Sum will get you ahead on the climbs, keep you there on the flats, and power you through the sprints. Decisions, decisions… made easy. With a layup engineered to maximise aerodynamics while keeping weight low, the design process for the Sum allowed us to strip away all unnecessary weight within the new aero profile tube shapes - all while maintaining maximum power transfer.

Maths does however have a wonderful logic and precision. Having been one of the first people to ride the new Argon 18 Sum Pro , I now understand the name. It is a very clever sum indeed. My specialty is ultra endurance road, having cycled around the world twice, both in record-breaking time, which takes a very specific type of road bike. But whereas most professional cyclists will only ride their team bikes, my role as a GCN presenter means that I get to ride a huge variety of bikes.

The weight isn't exceptional, but the components used indicate that there are numerous ways to reduce it if you wished to. Langsam replied to ShutTheFrontDawes 1 year ago 1 like.

Call it the sum of the best parts of their Pro-level road racing platforms, combined into one superbike…. It gets the same light weight premium carbon layup as offered by the all-rounder Gallium Pro race bike, balancing race-ready stiffness with all-day rider comfort.

The Rubino Pro TLR tyres will, I think, when run tubeless, improve the ride further than the tubed ones on our test bike. The weight isn't anything to write home about, but the bike manages to convey a sense of urgency while climbing. Sorry, I'm too much of a bargain hunter and it costs me nothing to keep around an unused account if they don't have anything that I want. Rate the tyres for value:. I ride an XL frameset and chose all-season tires, but even still the complete build weighs in at 7. This makes the bike feel heavier than it is. I can't talk about value for money over brand though, as I have what friends have described as the Specialized demo fleet in my garage. How was the bike in terms of height and reach? But it does have a noticeable by which I mean not significant but also not imperceptible difference in acceleration. Did any part of the bike feel too stiff or too flexible?
