Hi folks,
Today I picked up a year old 2013 Specialized RockHopper. After going over the bike with a fine toothcomb, adjusting, lubricating, and cleaning, I took the 29er on its maiden voyage. As I was going uphill, I tried to upshift from the crankset middle cog to the smallest cog and the chain got stuck between the chainstay and the crankset.
After doing some research on the possible causes, it seems that a bent or damaged tooth on one of the crankset cogs is the likely culprit. After examining the crankset I found a tooth that seems to have been damaged and is not as pointed as the other teeth. I am attaching a picture for reference purposes.
Do you think this damaged tooth is the source of my chain suck problem? Should I take this as an opportunity to replace my crappy SR Suntour PFF crankset with something nicer? What about the bottom bracket, should I replace that too while I am in there?
Thanks in advance!
P.S.
Some of the troubleshooting steps I have taken are as follows:
- Cleaned the chain and made sure there were no stuck links
- Adjusted front derailleur per Shimano instructions
