Got a 1994ish Bridgestone MB4 that I want to turn into a 650B gravel bike. Any advice is appreciated. : r/bicycling

For example, you can use it to store a spare tube, multitool, CO2 cartridge, snacks, and your car keys

I built up my BlackHeart as a singlespeed, with the option to easily convert it to 1x drivetrain by slapping on a cassette, shifter and rear derailleur, but I had so much fun on the singlespeed that I have no plans to add gears
