It seems I am always tinkering with my bicycles. No, I am not a mechanic and do not have the ability to be a mechanic, but I do work -- or tinker -- on my bikes. I can change a cassette, clean a chain, change tires, clean the bike, adjust this or that.

What I have noticed is that the more expensive my bikes have become it seems they need more tinkering. Basically what this means is that a more finely tuned bike requires more maintenance than a "workhorse" type bike.
