So it wasn't just my brakes rubbing. It turns out the my rear bearings were intermittantly seizing up. Yep. That's probably why it was extra painful to ride a simple, flat ride the other day. My entire rear wheel was basically dead.
The guys at Technocycle fixed up the Kona, though -- repaired the cramped bearings, trued the rear wheel and installed some new rear brakes. Biggety bam. Just like new.
Yesterday, meanwhile, I did a quick 10 miles of climbing in the rain. And a lot of really, really cautious descending. In fact, I tried to ride up North Galen in the opposite direction. But when I turned right onto Preston, the switchback descent was -- sorry to say -- too scary in the pouring rain. This is something I have to overcome. Soon. I love climbing, but I can't be hindered due to the descents.
On Sunday, it's supposed to be 95 degrees. I can't wait. But as painful as it'll be, I'd hate to be the pros in Philly hitting the Manayunk Wall in that heat.
