I'm on APEX 35mm on a PFL Copa, and they are DREADFUL. they are so so crashy. They handle incredible on any road that doesn't have a bump. Train crossings? say goodbye to your spine. They are SUPER low at the front which looks really great, but honestly spend the extra money and get the H&R's, I will be going for them in the new year, Ride Quality is severely reduced on Apex
