Manitou Mastodon Comp Fat Bike Fork

6 reviews   |  

STOCK NOTICE: Out of stock. Check here for Mastodon PRO inventory.

The Manitou Mastodon Comp 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.

From Manitou

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.

Worth it!

It was a long wait to get it, but I'm happy I waited! Just got it put on and went for a ride. Action is smooth and very responsive! I could tell I had much better traction over my old ridgid fork. Feels great on sand and rocks! Looking forward to more rides with the Mastodon!
