My dad was a farmer by upbringing and, later, avocation.
By vocation, he was a mechanic and from the time I was 12 and all through college that was my summer job. So working on bikes comes pretty naturally to me. The only thing I have not done yet is replace a head set.
I've read that by the time you replace your chain three times, it's time to swap out your gears. That time came this weekend. I had a Truvativ crank with an otherwise Ultegra gruppo so I bought an Ultegra crank, bottom bracket and cassette (went from an 11-26 to an 11-28) and set to work.
Pretty straight forward though not quite as easy and smooth as I had thought going in to it. I think I got it right -got to buy a new torque wrench- and it survived its 7 mile installation lap which included some considerable effort. The bottom bracket squeaks a little more but all-in-all it's smooth and quiet.
Just a great way to spend 4 or 5 hours on a sunny Saturday afternoon.
I'm realizing my next bike might not be a bike but a frame
I have all the components I need.
