Dropouts are carbon.
I think 56 is the largest you can get.
Mine has a uniform matte finish which tells me it's clear coated with matte paint.
It's pretty stiff but feels better to me than my aluminum frame road bike. It didn't beat me to death on the rough rural roads.
I use Conti 4000s II 25mm tires which are actually larger than 25mm. I can't personally say if you could fit 28's in there but these fat 4000s II tires work.
I rode in a century ride Saturday and I am in love with this frame. It's the first time that my hands didn't hurt after so spending long on the bike, 103 miles - 6:29 riding time. Anybody wanting a carbon race frame it's one of the best deals, if not the best, going right now.
