I have a Giant TCR2 that I have had for a couple of months now. Great bike, lovely to ride but the one reservation I had before I bought it was that it came with a triple chainring set ( Shimano 105 52,42,30 and a 12 - 25 cassette ). Its not too hilly where I live and my preference is for shorter faster rides as opposed to all day tours. I have not needed to use the 30 yet. I am only 35 and 160lbs and consider myself fairly fit so I am considering converting to a double ( 52, 39 ) and 13 - 23 cassette. A setup I have used over the last 20 years.
I have read many of the previous posts on the double v triple question and understand that I can simply replace my 30 and 42 rings with a 39 and change the rear cassette without any problem. However will the rear mech and also the front mech require changing ? I have read in some adverts that different mechs are available depending on wether or not you have a double or triple.
Opinions welcome.
Thanks in advance.
