Is there certified status for bicycle mechanics? And does anyone know of a trained and conscientious mechanic in the Portishead area? I had my bike serviced (a basic one) before the Dartmoor Classic at the local bike shop. All seemed to be in order, albeit with the rear brake rubbing very slightly on the rim (discovered whilst turbo training). Didn't think much of it and didn't get time to take back to shop for checking, so had to wait to look at it at the hotel the night before the event. Hubby and I thought it was just cable tension causing the problem and tried to adjust but made no difference so had to wait till morning to get the Performance Cycles mechanic (who knows his business!) at the event to check it out. Turns out the whole brake assembly was loose where it attaches to frame and causing the brake to stay locked (no rub/locking after he tightened that up and gave it some lube) and could do with an individual servicing. I was not happy that my local mechanic that I paid money to, had neglected to make a basic check that all things were tightly attached! So, as I'm not a very mechanically inclined female, I would like to find a mechanic who knows what they are doing!
