I have a 2007 Trek Pilot 5.0 with a 105 crank 50 39 34. (Ultegra 10 cassette)
I would like a bigger chainring because I am running out of speed (topping-out).
I also rarely use the smallest chainring, so I might (might) change to a double.
How do I know what type of BB I have, and what is comparable if I do decide to change the entire crank? ( am very mechanically inclined, but ignorant to what is comparable to what). Any good bike mechanics books to look for that cover a lot of this stuff?
I am not a racer, and ride about 1500 miles a year. Most of the terain is rolling hills, and most of my rides are 20-25 miles.
Any suggestions on types of cranks to look at would be greatly appreciated.
Thanks in advance,
Bob
