The 2011 Fox 36 fork now comes in a 180mm option for the freeride masses, relatively light weight but with more travel pushing the Fox 36 family into new territory. While this was a natural progression for their series, it's not a new fork that's interchangeable within our range with standard 160mm options. The axle to crown length may not be dramatically longer, but the added stress this puts on the frame is cause for concern on bikes designed with a maximum length in mind. So, if you choose to ride the 180mm fork on an Alpine 160, you do so at your own risk and at the cost of your warranty. There are frames in development more appropriate to this fork, so stay tuned for 2012 if you're looking for something more aggressive.
