It is fascinating how many different kinds of bicycles there are! Just when I feel like I have a handle on how to repair a particular part of a bicycle, in rolls another bicycle to challenge my ability! But then again it is a reason for my continued interest in helping the GABA (Greater Arizona Bicycling Association) group repair bicycles at various Boys and Girls Clubs in the Tucson area. Besides the fact the young people do not have an air pump or do not know how to use it to care for flat tires, there are other needs such as new brake pads, inner tubes, chains, seats, and/or tires. In a 3 hour period of time, many bicycles get fixed and I learn something new each time too! It’s a great way to spend time with friends also! Good work all!!
