A couple inches of snow fell yesterday morning and, with the streets covered, I decided that a mountain bike would be my best option for a powdery morning commute. I pulled my GT Outpost down out of storage, bolted pedals onto the cranks, and set off for work. A block or so down the road, I shifted onto the big chainring and nearly immediately noticed the chain jumping - especially when I mashed down on the pedals to pick up speed. When I arrived at work, I quickly discovered the problem: the bottom bracket spindle was loose inside the housing and wobbling pretty badly.
When I got home that evening, I pulled the bottom bracket out and replaced it with a used one I had stowed away in the shop. The cranks are spinning nicely now. Turns out the rebuilt Truvativ bottom bracket that I installed on the bike in April was a piece of shit. So I replaced it with a cheap Shimano that I've had for years and simply refuses to die.
Despite the mechanical problems, it wasn't a bad commute. Since the snow was still fresh and not too deep, I got plenty of grip with the 2.0 inch Bontrager knobbies that are on my mountain bike. I meandered over to the Jordan Valley Greenway and took the trail for about half my trip, which gave me a nice respite from riding in traffic in poor road conditions. It didn't take me much longer than usual to make the trip from home to work, even with a short stop on the Greenway to snap some pictures. Not too bad for a frigid snowy Thursday morning.
