When my son started at age 15 doing triathlons and crits on his on a Specialized Allez with 105 ($700) and regularly finished ahead of others with much more expensive bikes. At 17 he saved up enough to get a Cervelo P2 with Rival ($2100) and again finished ahead of many with Dura Ace. He replaced the Allez with a Trek Madone 6.2 with Force at age 21 since he was working at a LBS and got a mechanics discount. He chose Force over Red purely for the cost savings and he felt that Force with wear less.
The point is you can't speed if you're not already fast.
Now I went with Red eTap from Rival simply because I could afford it.
