This morning was a great ride, a little tailwind to make it nice and easy. But when I was about a half mile from class, I started to feel my right pedal wobble a little bit. It was a very strange sensation, so I walked it the last half mile because I didn't want to destroy my crank arm and my pedal. After class, I walked the bike the mile over to the lbs and their tech called it a warranty repair so I got two new pedals and a new crank arm (I tried not to destroy them by not riding but the damage had been done) and the nice fellow straightened my rear derailleur hanger for free cause he felt bad that I walked my bike a mile and a half today. You gotta love the customer service at a good bike shop. I wish I hadn't walked all that way, but all and all not a bad day.
