Brian Dobiaswrote a review of Maxxis Ikon eXC/3C/EXO Tire - 29in on December 9, 2013
These tires as described are low profile and fast rolling. They have more volume then other race tires and the EXO sidewall gives it some extra strength in the sidewall. I've ripped through two small block 8s sidewalls in 2 months and haven't had a problem with these sidewalls. This is a popular tire in Utah.
