Polygon Helios 200 Shimano Sora 18 Speed, Carbon forks

[bicyclesonline]

The Helios 200 has Sora components, where as the 300 has Tiagra with the main effect being that its a slightly different way that the shifters work. The wheelset on the 300 is slightly better too. Lastly the bottom bracket is more sturdy, with a wider platform to reduce flex and transfer more power to the ground. Hope that helps.
