I've been beating on this Hardrock for the past 5 years. I ride 99% on the road doing hills and lake loops. I spent $350 on this bike and so far only upgraded the necessities.
Continental sport contacts tires
I have a nice Cannondale R1000 I use for my more serious rides and I'm not interested in a new bike. I just want to upgrade components as I wear them out. After a tune up visit to my local LBS the guy tells me the reason I keep having issues with my derailleur is it's bent and can't be adjusted farther. He was able to get it to run true but he doesn't think it will last, he wasn't trying to sell me a replacement so I have no reason to doubt the guy. The derailleurs are Shimano Acera and from what I have researched they aren't that great.
I ride alot of local events and group rides with a couple Clydesdales so this bike suites my needs. I like this tank and would like to keep it for many years to come.
What I want to know is should I just upgrade the front derailleur or go ahead and replace both derailleurs? I'd like to hear suggestions on what would be a good solid option.
