Chris King Bottom Bracket Grease Purge

So I ordered the Chris King bottom bracket purging tool and thought that we had everything that we would need to provide this service. Turns out that we also needed a grease gun with a Zerk fitting, you can't just use the typical grease gun. I found this hand pump that comes with Phil Wood grease tubes.

Now that we had the tool we had to try it out so Sam brought in his bike. The first thing that you have to do is remove the black plastic ring.

Then you plug the tool into the bearing and start pumping new grease. The old grease and dirt gets purged out. It's a pretty slick system. We now have all the necessary tools to perform this job at our West Bank and Midtown locations as well as on the Mobile Repair Unit.
