Specialized Gravel Bike - Convert 90’s Mountain Bike to Gravel Bike
In this one, I convert a 1990’s Specialized Stumpjumper mountain bike into a modern gravel bike, complete with drop bars, disc brakes and tubeless tires. I do it right and I make it modern. You can do it too! The end result is a beautiful bike that I can ride anywhere I’d like to go. And I’ve saved another 90’s MTB from the landfill.
