It's awesome

By Nick Mazzone from US, Illinois

I have ridden this bike for ~3,000 miles. This bike is unreal. It handles super well and it is fast. Looks great, especially the blue. I can not wait to upgrade the wheelset and see how fast I can get this bike to be. Well worth the price in my opinion. I thought I would still ride my old road bike sometimes after getting the Gallium CS. However, my old one just does not compare. This bike rides and handles so much better that I hardly use my previous road bike. The only thing I changed was the seat, the standard one was uncomfortable on longer rides. Stoked to keep putting the miles on this bike and I will absolutely buy another Argon when the time comes!
