The Manitou Mastodon Pro fat bike suspension fork is a long awaited and worthy competitor to the Bluto. Cold tested (wink wink) and ready to ride, the Mastodon is a great option for people looking to add front suspension to their fat bikes.
Some people claim that fat bike tires run such low pressure that they act like a natural suspension fork, but if you've ever ridden a mountain bike on a trail, you'll know the difference. The Mastodon helps smooth out your ride and really let's you take your fat bike anywhere.
Real-world trail suspension for your fatbike! All-temperature performance soaks up chatter and big hits on freezing cold snow as well as it does on shimmering hot sand, and everywhere in-between.

I bought this Mastodon to replace an older Bluto on my fat bike. It's far better. Whereas my Bluto suffered from lots of "stiction" (only briefly made better by a rebuild) the Mastodon is smooth from the start. I've only taken it on a couple singletrack trails so far but the difference is sufficiently dramatic that I highly recommend it.
