Free Bike Wheel Tools-- Nipple Inserter and Power Drive Bit

Here is the scenario. Your spokes are stretched, you can no longer true your rim. Maybe it's time for replacing the spokes with new and save your hub and rim from the dumpster.

Cut the spoke to about 6 inches long.

Grind or file to a point

An electrical wirenut works perfect for the cut side.

Insert the pointy side into the nipple and slightly turn, the nipple will attach to the inserter. Then place in rim hole and attach spoke to nipple by turning wire nut cap.

Use the nipple to cover the pointy side for storage.

First you start with a flatblade bit. If you have ever laced a rim, you know there will be lots of turns with a spoke wrench initially. This will speed up the process using a power screwdriver. I would recommend a slow rotation screwdriver, 200 rpm or less

Start filing or grinding the bit back leaving the center as is. Constantly check with a spoke nipple. Take your time, speed is not your friend here.

When it is done, the point will fit into the hole of the nipple and the edges will fit the slot of the nipple. A great timesaver.
