Took a 2012 DS 8.4 for a ride today since it was in my size next to us and the door. It felt much closer to the previously mentioned Cannondale(heavier albeit), and further away from the FX series I rode the day before. I'm not sure if I can swing it for the 8.4, but pretty sure the 8.3 if that's what I decide. I really enjoyed the ride on it. The handlebars could maybe go up an inch higher and I would be happier. I'd like to maybe change out the tires to a flat top with knobby side tires(I know, probably not the right terminology) like I've seen on other peoples bikes in the forum. I liked the hydraulic brakes as well. I didn't even realize they were until after I brought the bike back up to the shop, I thought it was just a different feel because of being disc. I'm hoping to maybe pull the trigger on a bike in the next 7-10 days.
