Quick inital review, I love it.
The frame is different, the tubes are not round they are triangular due to hydroforming or whatever they call it. The top tube as you look down is completly flat. That said the frame feels nice and stiff the few sprints I have done for fun have felt crisp and no loss of energy felt in the frame.
For me I really like the stock seat for comfort so far
The fork is taing some getting use to coming from a suspension fork that eats up all bumps.
The only thing I can say bad on the bike so far is the brake rubber, The brakes feel fine but I think the rubber is poo poo, or I just like a little more bite personally.
Honestly I think I got alot of bike for the $$ and I can see this as a bike I will upgrade to better components as time goes on rather than look for a new ride. Up grades are 1/2 the fun in biking and automobiles
