I have been running a Trials tire up front, and its been great, I have been wanting to replace my rear tire for something "different" for a while now, and while i have been lusting for the duro, I like the look of the Maxxis Ceros and ordered one up today from the local shop. They seemed confident in mounting, and even included the mounting in the price of the tire, so i couldnt pass it up. Its supposed to be in thrusday or friday, so I am excited to get my new tire on. I ordered up a a new chain and sprocket set also, i had been running the 15/50 combo, but went back to the stock 14/50 for the larger tire. Anyone else here have a Ceros?
