Bike looks to be able to take bigger yet , wont happen anytime soon. Yes I am still running tubes.
I've found that you have to relate the tire size to the rim width. I currently have 28s on my older Madone, mainly because I couldn't get 26s. But they are too wide for the rims. The cornering is a little mushy because the profile is so much wider than the rim. Also, mounted narrow rims, they measure only about 26.5 mm wide, fully inflated. This is probably why they don't feel appreciably more comfortable than the 25s I had been using. Also, they're difficult to push past the brake pads when fully inflated.
