I show how to install dropbar handlebars and integrated brake shifter levers (brifters) on a mountain bike (with 26" wheels) to build a touring/monster cross/gravel bike. I also change from V-brakes to cantilever brakes for compatibility to the road brakes. And also swap out the mountain front derailleur to a triple road front derailleur. The bike I used for the conversion is a 1998 Cannondale Birkenstock M400. And yeah, I know the wheels need to be trued.

* I switched from v-brakes to cantilever brakes because cantilever brakes have the same cable pull ratio as road levers. V-brakes require nearly double the amount of cable pull to operate properly and won't work correctly with standard road levers.

* I did not use Mini V-Brakes as they only work with tires up to about 38mm wide. I could have used a Travel Agent, but they are known to fray the cable with it goes through the pulley. I chose cantilevers. I'd like to point out that manufacturers like Trek and Surly use cantilevers on some of their current bikes. Check out Surly's Long Haul Trucker.

* Shimano SIS rear derailleurs all have the same cable pull ratio. There is no difference between a road rear derailleur and a mountain bike rear derailleur as far as cable pull ratio (note: 10 speed mountain changed). But Shimano road and mountain front derailleurs have a different cable pull ratio. Since I was switching from mountain shifters to road shifters, I had to change the front derailleur, but not the rear one.
