Hey guys, today I'm going to replace
the broken spoke nipples from my Trek 720 Multitrack
Firstly, take off the tire and rim strip
The only way to take off the nipple is to unscrew it from the inside of the rim
A flathead screwdriver won't work because the spoke is sticking out
A plier won't work either
Find a flathead tip, grind the middle of the tip using a Dremel cutting wheel
Cut a slot with the required amount for the spoke clearance
Now use the tool to turn it counterclockwise
Don't turn too hard because you might strip it
And finally, replace the nipples and true the wheel
