Once I was back in my shop, I was able to do a better test to determine it was the axle. The BB is the only thing that remains stock on the Trek at this point, and since I don't know much about its history I can only imagine how many miles it has on it. I also suspect my recent intermittent sprints during my commute probably didn't help, and a rather intense sprint that I did on my last stretch of road before pulling into work yesterday morning is probably what did it in.
I didn't have a spare BB to install, and every shop was closed at this point, so all I could do was angrily wrap my bars with some new Lizard Skin tape.
|ARE YOU HAPPY NOW|
|Beautiful day today...if I can't ride outside, might as well work outside!|
|You served me well.|
|Brand new and ready for lots of mileage!|
These two thankfully used the same tool for installation and removal, so I didn't have to buy another one.
|One of the many types of Shimano BB tools.|
Everything got cleaned and regreased, and installation was easy.
|Fresh new axle!|
Anyone wondering, the belt just kind of hangs out when I pull the crank.
|Just hangin' out.|
|Pretty spot on!|
The belt tension felt a bit high, so I adjusted it down a bit. It's the same as tensioning a chain, just a slightly different dropout design on this particular District.
|First these are loosened.|
There are a few areas that can be tweaked to adjust tension. The dropouts themselves have to be loose, and then the tension bolts are tightened or loosened.
|These little guys.|
After a few minutes and only getting my finger almost chopped off by the belt once (if it were a chain, I probably would be missing a thumb right now) everything was good to go. I'll test later to ensure everything is playing nicely together, but right now I want a smoothie.
The whole process maybe took thirty minutes. I think the most time consuming thing was cleaning the grease off my hands to take photos!
