“Entry level racing frame with high end features”
The Polygon Helios A5 is Polygon’s aluminium framed entry level road racer. The A5 frame has features found in frames priced at mid range or higher. The frame tubes use sharp angles and minimal curves, with some aerodynamic design. The chunky down tube slims down to a tapered shape at the bottom bracket, adding stiffness to the bottom end. The carbon fork is light and stiff, giving a weight saving. The shaped fork blades also add to the aerodynamic profile of the Helios A5.
The groupset is Shimano’s 105. This dependable and capable groupset fits into the nature of the A5 as an entry level road racer, and will give the rider many miles of trouble free riding with minimal maintenance. Shimano also supplies the RS-11 wheelset. This entry level wheelset suits the Helios, without spending on high tech materials. The rest of the equipment is Polygon’s house brand, Entity. No fancy carbon here, just dependable aluminium.
This allows for future equipment upgrades, as performance improves and budget allows.
Riding the Helios A5 shows it is an entry level racer that gives confidence in the bike’s handling and performance. While the frame is not as stiff as similar carbon offerings, the A5’s estimated 8.8 kg all up weight isn’t something to be ashamed of. The riding position is somewhat upright, again suiting the Helios A5’s intention of being suitable for the entry level rider or beginner. It would also be ideal as a training bike for the more experienced rider who wants to reserve his ‘best bike’ for the Sunday ride. For riders looking to only have one bike, and aren’t interested in high performance or exotic materials, the Helios A5 will fit into that niche very nicely.
