Ask this Kona rookie how that bike worked out!!!

Probably zero. The old P2C is still a fast frame, especially if the long and low position works for you. With a few modifications it’ll be 99.9% as fast as a modern tri bike, faster than some.

I don’t drink while on the bike

Does the down tube bottle help with aero dynamics?

What about a regular bottle between the handle bars or an aero bar?

Not really but hydrating will definitely help you go faster :)

When I went from my 2009 P2 to my 2014 P2 (bought new in Dec 2015) I didn't notice any speed difference.

I just wanted a new bike.

If you have a gap between your arms then putting a bottle between them is usually considered faster than no bottle.

Down tube may depend on the bottle. I would think the classic P2 is faster without a bottle on the down tube given the entire tube is an airfoil shape. Curvelo published some data a few years ago and said a bottle generally high up behind the seat could be faster, and generally not slower, than no bottle at all.

If I was racing short course on a P2 I would just go with a bottle between your arms.

Very little. The P2 has barely changed shape/weight in 10 years.

Great info

Thank you to all who replied

i have a good friend who makes aero testing for bike components as his job and i saw the frame test data. between the slowest and the fastest, there are 15Watts difference.
this is the worst case scenario you can lose having the worst in the market (P2 from 2008 is not the worst on that list though...)

The P2C allowed for short and tall fits, the P3C was long and low, especially for larger sizes

Right, sorry, I meant compared to the new p2/p3.

Yeah, but all of those exposed cables and lack of an extra cog on the back are really hurting you! (Pink)

We all definitely ask that same question. I wish I knew the answer (2008 Specialized Transition Elite, if anyone cares to chime in), but in my case, my bike handling skills suck (I ride exclusively on a trainer) and my FTP is only 3.6W/kg. I've resigned myself to not investigating other alternatives until I don't weave around like I'm drunk and my FTP is at least 4.2W/kg.
But if I had a lot of money, I'd probably go out and buy a new bike tomorrow. Lol.
