Bottom Bracket bearings shot - is it my riding style?
I commute to work on my bike 3 or 4 days per week, and ride additionally on other days. Generally my ride duration is 40 to 50 minutes. Fitness is one of my major goals. I tend to keep in a lower gear and spin fast to keep my heart rate up. I also tend to power up hills in the same gear. I'm pretty strong and on the heavy side.
Riding home from work, my bottom bracket started skwauking badly - so I assume it's the bearings.
So am I doing damage by powering up the hills?
