I am riding a three-year-old Trek 7300 Hybrid.
For the past several weeks I have been feeling a "ratcheting" while pedaling. I don't hear anything with it, but feel this in my feet. Does anyone have any suggestions as to what might be causing this and what I can do to fix it ? I am not very knowledgeable about bicycle mechanics but would like to try to fix this.
Here are the details: The problem began about four weeks ago. I feel this "ratcheting" in my feet while pedaling, but do not hear any noise. It is not affected by the position of the front derailleur, but MAY be worse with the rear derailleur in gears 4 or 5 but I am not positive about this.
Two weeks ago I brought the bike into the shop for its annual service and I told them about the problem. When I got the bike back the ratcheting was worse
I guess they tightened the cables because I can get into gears 1 & 2 on the rear derailleur and gear 3 on the front derailleur more easily but am having more difficulty getting into gear 1 on the front derailleur.
Other than returning the bike to the shop (not as easy as it sounds due to distance & traffic & time), does anyone have any suggestions for me ?
