The upated Polygon Helios A road bike cuts 150 grams, adds SRAM UDH and a threaded bottom, and an aim toward improved livability.

Polygon’s Helios A undercuts the big brands and claims to offer all-round race performance. Can it deliver on both price and ride?
Undercuts big brands on price
34 mm tyre clearance for versatility
Ability to swap between proprietary aero seatpost and standard 27.2 mm round post
Potential for greater compliance and comfort with round seatpost
Brand seemingly unsure how to define the bike (race or endurance)
Frame geometry remains fixed, limiting transformation into a true endurance bike
