A9X PRODUCT FEATURES
LOOKS FAST – FRAME DETAILS
BLINK AND YOU’LL MISS IT
When it comes to frame finish, this IS the bike – subtly changing between different purple hues as the sunlight filters through the leafy canopy, hitting the frame, whilst you descend those picturesque switchbacks. From the details on the seat stay, textures on the downtube, and deep etched Polygon logos on the forks, you’ll not only feel fast but look even faster. Whether you’re cruising to the cafe with the local bunchie or ripping it in a crit, you’ll definitely be turning heads.y.
THE PERFECT COCKPIT
AERODYNAMIC – ERGONOMIC – REINFORCED
BLKTEC and Token joined forces to create the R8 bar – showcasing the perfect balance between ease-of-use and aero engineering. The adjustable cover permits routing without removing the stem so that you can easily install and upgrade your cockpit. Better yet, the R8 setup looks the part – keeping you looking fresh whilst out on the road.
SLEEK GPS MOUNT
PRACTICAL – EASY INSTALLATION – AERO
We know it’s hard to find a suitable cockpit that has a practical GPS mount – one that’s both easy to install and isn’t an eye-sore. With that being the primary mission, we chose to fit out the A7X with the BLKTEC R8 cockpit for its easy access GPS port – allowing for additional attachments when you’re ready to travel off the beaten path.
DEEP-SECTION CARBON WHEELS
AERO – LIGHT – STIFF
Perfect for undulating courses (reducing efforts at higher speeds) and time trials, the Entity WR5 (50mm) carbon deep-section wheels prioritise aerodynamic efficiency and are ideal for impact absorption. Oh and who can forget, they look bloody good (especially alongside the chameleon purple colour of the A7X).
LIGHT UCI APPROVED FRAMESET
LIGHT – APPROVED – RACE-READY
Tried and tested by one of the best UCI continental professional cycling teams, Terengganu Polygon Cycling Team, the Helios needs to live up to a certain standard – as you’d expect. Well, now you can be confident that if you’re a serious racer (or aspiring pro), that your bike will meet the UCI (governing body for professional cycling) technical standards; thus, you’ll be able to mix it with the big dogs – not stressing about buying a new bike that meets the organisations’ standards. Approved frameset aside, the ACX frame weighs approximately 800g and if we look at the A7X as a whole, the total weight is 8.1kg.
WIDER TYRE CLEARANCE
OPTIMAL ROAD ABSORPTION – VERSATILE
Coming with the new industry standard 28mm tyres, the wider tyres (relative to 23 & 25mm) are optimal for a variety of both weather and road conditions. Moving away from 25mm tyres, the larger tyres offer better grip (which are GREAT when it comes to rainy conditions) and provide ideal comfort without compromising on rolling resistance (relative to larger tyres, such as 32mm).
GEOMETRY
RACE-READY GEO
FROM BREW STOPS TO THE CRIT TRACK
When it comes to geometry, we (roadies) care about comfort and performance. The Helios was not only meant to fly up hills and be railed on descents, it was also meant for long days in the saddle. The Helios was designed to hit the sweet spot – providing you with the perfect balance between stability, descending capabilities and power transfer. From the long wheelbase (approx. 1000mm *Size L) for a more stable ride (lower center of gravity) to the slacker head tube angle (72.5 degrees *Size L) for predictable steering, the Helios was meant to be raced. On top of that, the seat tube angle is on the steeper side (73.7 degrees *Size L) – positioning the seat in a more forward position, allowing for an optimal aero tuck. Whether you’re looking to put the power down in a sprint or beat your mate to the cafe, the Helios is the bike of choice.
24% REDUCTION IN DRAG
INDUSTRY LEADING
Polygon has completely re-designed the Helios lineup – using cutting-edge technology to boast an industry-leading 24% reduction in drag over the previous generation. In addition to the improved drag reduction, the design of the Helios was predicated on authentic riding feedback – gaining performance insights from both professional riders and amateurs. This resulted in the integration of suitable reinforcements along with a larger tyre clearance – enabling you to effortlessly control, corner, and conquer even the most daunting of terrain.
RACE-WINNING DNA – MAXIMUM POWER TRANSFER
OPTIMAL POWER TRANSFER
From the flats of Turkey to the high mountains, the Helios has proven its dominance – helping the Terengganu Polygon Cycling Team rider, Jambaljamts, win the general classification, Sprint classification, and KOM classification during the Tour of Sakarya. When developing the Helios, Polygon focused on maximum power transfer – reinforcing the bottom bracket and right chainstay to instantaneously transmit pedaling power to the wheels.
FEATURES
SHIMANO 105 DI2 R7100 GROUPSET
ELECTRONIC – PRECISE – FAST
The groupset we all know and love, but better. The new Shimano 105 R7100 Di2 is the most revolutionary road groupset Shimano has ever released. From the 12-speed cassette, electronic shifting (up to 3 years of battery life with easy-to-change CR1632 batteries), more gear range, and 10% increase in pad clearance, this is the groupset you’ve been waiting for. Just like Dura Ace and Ultegra, the new 105 Di2 is highly customisable – using Shimano’s user-friendly E-TUBE project app. Now you can set up your drivetrain exactly how you want it, all with a touch of a button. Not only is this the biggest tech revamp 105 has ever seen, the hoods are similar to Dura Ace and Ultegra – giving you a sleek and ergonomic design/feel. This newly beefed up groupset pushes 105 beyond entry-level.
BUTTERY SMOOTH SHIFTING – ANY TERRAIN
ANY TERRAIN – SMOOTH SHIFTING
Boasting wide ranging gears, the 12-speed 105 comes with an 11-36T rear cassette – allowing you to easily pedal up daunting climbs and push on descents. Along with the large range, the cassette spacing is narrower, allowing for seamless shifting. In addition to being able to navigate any type of terrain, the move towards electronic shifting provides you with unparalleled shifting performance – experiencing faster and smoother shifts under maximum torque (pedalling force).
105 R7100 HYDRAULIC DISC BRAKES
WIDER CLEARANCE – QUIETER RIDE – EASY MAINTENANCE
Yes, we hear you, we hate when our disc brake rotors rub. Well, with the new 105 hydraulic disc brake calipers, that is less of an issue – thankfully. The new lightweight mono-body construction design provides you with 10% wider pad clearance, eliminating that pesky ‘Whoosh’ (quieter braking system). But that’s not the best part, if you’re into home maintenance, the new one way bleeding system allows for simple maintenance – streamlining the oil route throughout the system to prevent air bubbles from being captured in the system. Alongside the maintenance friendly bleeding system, the SLX disc brake rotors deliver both powerful and consistent brake performance for all riding conditions – allowing you to tip in with confidence.
ENTITY WR5 DEEP-SECTION WHEELS & 28mm SCHWALBE ADDIX TYRES
AERO – LIGHT – STIFF
Simply put, the WR5 wheelset is near perfect for most terrains – whether you’re going down a steep descent or ripping it up your local KOM. The stiff spokes along with the stiff carbon body allows for optimal power transfer; allowing you to travel faster, with less effort. Along with the deep-section Entity 50mm wheelset, the A7X comes with 28mm Schwalbe Addix all-round road bike tyres, providing you with a balance of protection, durability, rolling resistance and grip. Straight out of the box, the Helios A7X comes with innertubes; however, the WR5 wheels are tubeless compatible and can be easily converted once you’re ready.
