I'm currently using michelin Carbon's on my durace 7800 wheelsets. I've mounted and dismounted over 100 tires, but it's just plain pain to mount the carbon's. I only went with them cause it's durable, decent grip while still relatively light. I use my bike mainly for commuting to work, so being stopped on the side of road for 20minutes trying to mount/dismount a tire is just frustrating. Any other tires out there that is good and easy to put on?
