We have 3 boys that ride their bikes hard and constantly need adjustments/repairs. I have a lot of the necessary tools and try to repair them myself but can never get the brakes (V-brake, center pull) just right or the derailleur. I'd like someone to come by and see if I need any other specialty tools for working on bikes and how to do tune ups, adjustments, etc. I think 2-3 hours should do it to start. I'd like to find someone that works in a bike shop ideally.
