Newer to the forum, have been reading up on all this info... finally don't feel like a big man out hahaha. I'm 6'4" about 260. Currently riding around on a Klein MTB but want a road bike BAD. LBS said CAAD 9 from Cannondale should be plenty strong for years and years... LBS said newer bikes are strong as steel plus with a 61 or 63 frame I will have comfort and a bit of flex. Is it true that AL is stronger now through tube shaping than maybe 10 years ago and will I have comfort. I will be riding 10 to 40 miles per day about 3 times a week. I want the bike set up in a more relaxed geometry (stem and seat) but the frame to be a road? Any imput appreciated!
