This deal allows you to upgrade, while using all of your existing parts, with the exception of the front hub. You will need to either relace the wheel with a through-axle hub, or replace it altogether.
I wanted to use a Manitou Mastodon fork, so I just sold the Bluto and helped pay for the Mastodon.
The Bikes Direct frames are never cutting-edge, even when brand new. But, how cutting-edge does a hardtail fat bike really need to be?
Using this as my all-rounder mtb, and I love it.
BONUS: Mine came with no decals or graphics. The stealthy flat black paint looks great.
