Fix People's bikes!

6 months ago you were asking some very naive questions about bikes and your local bike shop ripped you off and did some really bad work on your bike.

I would strongly suggest you get some proper training before you offer your services to other people.

From your list of services it appears you are not ready to do gears, which is one of the things that people frequently find problematic.

Not much of bike maintenance is rocket science, but it would be useful to ensure you have a reasonable knowledge base before you begin.

Yes but I have learnt a lot since then:)
