Sometime last year, a chap from another company on my office development cornered me to ask about bikes and commuting to work. He only lives a few miles away so subsequently got himself a second hand Marin MTB.
Roll on a year and a bit later he grabs me again and said that his bike shop said he needs a new chain and cassette and the gears sorted. I mentioned that he should buy the items and do it himself. He gave one of those blank stares. So I said if he get's the components I will do it for him.
So he got the new bits and one lunch time (I had bought some tools in) I showed and helped him change the components over. I also indexed the gears and tightened the brakes. He was surprised at how relatively easy it was.
He wanted to give me money for my trouble, but I said don't be silly, just buy me a pint one day.
Well a few weeks later, he knocks on my office door and gave me a pressie.
