Hey, all--
I'm in the market to upgrade my aluminum TT/Tri bike to a full carbon frame. I'm currently riding the entry level Cevelo Dual which has worked well for me on short-course races but it's a bit heavy (20+ lbs w/full Dura Ace) and the ride is pretty harsh espeically on longer (40-50+) rides now that I'm training for a 70.3. I'd like to get the light weight and stiffness carbon can provide along with the more comfortable ride. I've got my eye on what looks to be a pretty decent full carbon TT frame but it has external cable routing (the Cervelo has internal).
My question is this: Does having thin cables running the length of the top and down tubes really affect the aerodynamic properties of the bike all that much? Keep in mind here that I'm a 40+ age-grouper who averages around 22mph on my bike legs in Olympic/International distance races so I'm not Norman Stadler averaging 26mph. So much of bike marketing is hype and jargon and I'm just trying to get a realistic sense of whether external cables really has any signficant impact on how areo the bike is.
Thoughts and suggestions are appreciated.
Thanks!
