This is the best upgrade (aside from a fork upgrade) for the Trek Marlin or any entry-level mountain bike. Of course, this upgrade could be done on a BMX Bike, dirt jumper, road bike, etc.
I will be lacing the rim to a Profile Racing "classic mtb hub". Profileracing.com/store/
Disclaimer: I recommend watching other wheel building videos (with more details) to get an accurate and detailed list of steps on how to lace and true a wheel. This video is for informational purposes only. Work on your bike at your own risk.
Good luck on your next project!
