I spent a lot of time wondering if I made the right choice, and whether I should upgrade etc. Then I discovered that the more I ride, the less I want to upgrade or change my bike - it is only when I am not riding lots that I start looking at bike shops. So the solution for me was quite simple - ride lots, ride frequently - and since I am back to commuting by bike, this is daily
Yes exactly. Just getting on and riding a lot will help to identify areas like pedals or tires that could use improvement. Riding rather than second guessing will also allow one to identify and get used to the little quirks that every bike has.
