PLEASE help me. I never had a problem on my bike, but for the last 2 weeks I've had a constant pain in my left knee. I moved my saddle up by about 1cm without any problems. After about 2 weeks after moving the saddle up, I started getting the pain in my left knee (only left). Now for the other changes: 1. I started at a new company which involves me travelling 220km per day in my car. I drive a Citi Golf (old VW Golf 1 shape). Can it be the travelling? 2. At work I don't have the most ergonomic seatng arrangement. (My chair is f&$#*%). The chair catches me on the bend on the back of my knee. Can this cause the problem?
