Finally had a fitting done to my bike, as I am doing a century in 2 months and found that after being on the bike for 2 hours straight that things started to hurt a tad bit. One thing that I found was that I need wider handlebars, and I was told that I need "longer cables" to go from what is currently on the bike (42cm wide bars) to the 46cm bars. Do I really need to buy new cables...as cables are universal in length and I can just adjust what I have on the bike now?
For what it is worth, getting fit to your bike is the best money that you can spend. Not that my bike was completely jacked as far as fit, but I did learn a lot during the fitting...and that in itself was worth the coin.
