The Mayhem 140 is designed to run 150mm or 160mm up front. Default build spec is 150mm, but since every bike is built to order, going to 160mm is as easy as asking. If you currently own a Mayhem 140 and want to change fork travel, you don't need a whole new fork, you'll just need an air spring in the travel you desire. These are inexpensive and relatively simple to install.
