I have been reading posts on the site for quite some time now and find it very helpful. I just decided to become an active member and ask you more experienced folks for some guidance.
While I realize that it is more about me than the bike, I want to make some improvements to my bike and want to know the best bang for the buck for noticable improvements.
I have a 2010 Giant Defy Alliance 0. This is the version that is half carbon and half aluminum. I like the geometry and it is comfortable, but I am struggling to keep up on some rides and I am looking for any edge I can get on the bike. Granted, I am riding with more experienced riders and we average 18-20 on various rides.
The bike has Mavic Aksium Race wheels and complete 105. I was surprised to find out this weekend that the bike weighs 20.92 lbs. as weighed with saddle and pedals. I would have thought it would be lighter.
I have an opportunity to swap the 105 components for complete Ultegra (new) for $660.00. This alone would shave 8 ounces. The other item I am considering is a new wheel set. However, I am 6 feet tall and weigh 220 lbs. (down from 237 and hoping for 210 soon) and I don't want to buy the wrong wheels that won't support a heavier person.
