What is in a name? Bike names are normally abstract, words that sound cool.

At road. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything except locks but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value — with value determined by how a product compares with items of similar spec, quality, and price. Good scores are more common than bad, because fortunately good products are more common than bad.

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. Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning. We leave no room for compromise when we build bikes for the most demanding and passionate cyclists. It is agile, stiff, smooth-running and sensibly equipped. See configurations. All Together Faster. The Sum Pro in action. See our athletes.

There it's no such thing as an inertial force. While testing affirmed my reservations about some of the finishing kit, the Sum Pro is undoubtedly a quick and able race bike. The frameset is available in two versions: an upper-level Pro with a 'Pro Level Layup' composite construction, and an 'Elite Level Layup', as on the Sum that we have to test, argon18 sum pro.

The Montreal-based brand has achieved WorldTour-level success on the road and more recently on the track under the muscular Midwestern muscle of Ashton Lambie during his world-record-setting 4K individual pursuit attempt. This year Argon 18 announced it would be consolidating its road bike catalog following the likes of Specialized and Scott by ceasing production of its aero-focused Nitrogen and lightweight-optimized Gallium frames. In place of the two models, Argon revealed the Sum series that combines the best characteristics of each. Aero shaping can be seen with the hourglass-shaped head tube, airfoil inspirations on the downtube, seat tube and seatpost, as well as the Kamm tail-shaped fork that is intended to divert air away from the downtube. We like the engineered clearance for up to 32mm of rubber.

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 dropped seatstays and shaped seattube with rear-wheel cutout add in even more wind-cheating tech, while also increasing rider comfort by allowing more flex through the proprietary aero seatpost, with its hidden wedge clamp. Argon 18 says the new Sum Pro with its Pro-level carbon layup weighs g M painted frame , just ten grams more than the Gallium Pro Disc with the aero upgrades. The new bikes all feature fully internal cable routing thanks to an FSA ACR headset system, making routing compatible with any modern disc brake groupset — mechanical or electronic shift. The bike now gets big for road tire clearance for up to x 30c tires, which Argon 18 says is on a modern wide wheelset measuring out up to 32mm wide actual — max 32mm wide rims to fit between the stays, as well. The carbon Sum features 12mm thru-axles, flat mount disc brakes, and gets a pressfit BB86 bottom bracket. Ask your local shop for a more detailed estimate if you need a new race bike.

The Sum and Sum Pro share the same geometry but the Sum Pro uses a refined carbon layup to save weight. Geometry-wise, our size-medium Sum Pro mixes a steep A 54cm stack and

Reasonable performance — but these are not the wheels specified on standard bikes. We cyclists come in all shapes and sizes. The frameset is available in two versions: an upper-level Pro with a 'Pro Level Layup' composite construction, and an 'Elite Level Layup', as on the Sum that we have to test. Province Select. Argon Fit System is designed to provide riders of all sizes with consistent performance and optimal positioning. Matt is an endurance nut who loves big rides and big events. All Together Faster. Tell us about the materials used in the frame and fork? Details like the integrated seat post clamp and the updated 3D headset make sure that each aspect of the bike flows across joints, making it look designed as a whole, rather than a frame with accessories bolted on. 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. Maintenance-wise, we charged the AXS derailleur batteries once a week with the system performing without compromise. That said, I am a bike rider and not a journalist, so here goes. The Sum frame has lowered seatstays, a sculptured seat tube, and a head tube that flows into the down tube, giving it a very similar look to rival models. It is a very clever sum indeed. Would you consider buying the bike?

What is in a name? Bike names are normally abstract, words that sound cool. A Sum, by contrast, sounds rather utilitarian.

With the Di2 battery in the seatpost and the integrated cabling around the stem, I was a bit concerned about how easy the rebuild would be out of the box when I reached Spain. Thank you! It provides impressive performance, with comfort that belies its looks and sharp handling, but something doesn't add up with the pricing and the sum of its parts. The Rival shifters require a little more effort than the Force or Red AXS versions, but this is something you can adjust to. The wide rim improves airflow around the wider tire options that the industry has embraced. Submit your review. Having been one of the first people to ride the new Argon 18 Sum Pro , I now understand the name. Stephanie Wunderle Triathlon. Gallium CS Disc All the engineering knowledge of our pro-level bikes, in a more accessible package. Fast, but not in a way that makes handling difficult. We wanted to share with you the time it now takes to build a complete bike from the ground up.
