I have a pretty aggressive ride in a week. 80 miles with 10,000 feet of hard climbing. Not sure if a choice of bike will make any real difference but here are my choices.
1) Alum. frame Jamis with 50/34 front and Sram Apex 11/32 rear. Weight 19 pounds.
2) Full carbon Felt 50/36 front and 12/27 rear. Bike weighs 15.5 pounds.
So which bike would you choose given the options?
