I can (just) get 28c GP4000s in but have to deflat ehe rear to put the wheel in and the front rubs a bit on the fork crown. Need to take a file to the fork crown over winter, only needs the sliveriest sliver taking off.
The ride is really nice. Compliant without being theleast bit noodly. But no, not harsh at all.
Although I'm not a great judge of these things, this is only my third road bike in 30 years. Rather pathetic I know, considering the company!
I need to clean it up a bit, then I'll get a pic (or 2) up
