New Tt design vs old - time difference

Can’t seem to find any data on the newer Tt frames with intergrated front end and aero brakes vs the older normal design? Looking at the cost difference. Going to australian national TT and maybe the worlds as well.

Is there a big time saying on the frames?

There aren’t that many Bayonet bikes that you can use for TT. Pretty much TM01 and DA unless you can dig up a Speed Concept with legal bars and forks.
Most of the UCI legal stuff is a couple of years old now, there is almost always the possibility of gaining speed by careful equipment selection.
What are you using now and how are you set up on it?

The integrated front end bikes aren’t always the better ones either.

You can see quite a few comparisons if you peruse the bike data here:

As a rule of thumb, the modern P5/Speed Concept type bikes are compared to the older generation P3/Spec Transition/Trek TTX are about 100g of drag @30mph or about 40 seconds faster per flat 40k

You can narrow that difference some by using one of the top modern aero cockpits, careful cable routing, aero front brakes, etc.

Not intending to hijack a thread, but the “integrated front end” made me ask something I’ve always wondered:
Gen 1 SC 7.0, Tririg Omega and Ventus 2 vs

  1. `Gen 2 SC integrated front end and
  2. n.P2 with Ventus 2.
    For slower back of pack riders, with same super 9, front 808 or 1080, probably higher wind yaw angles than FOP guys. Close enough to a wash re the bikes?
    Thanks for any opinions, Jack.

I’d say between the three, “close enough”. Gen 2 SC will be the fastest of the three but by a very small margin… I’m guessing ~10secs/40k. It also has a really really really nice cockpit :slight_smile:

You can order the new SC in UCI legal trim and there are still some P5-3s floating around.

Appreciate the opinion, GP :slight_smile:

I think this article on the p4 gives some good insight:
http://www.slowtwitch.com/Tech/Cervelo_P4_in_the_Tunnel_1929.html

It is a little dated but it shows what a regular brake, good frame, good aerobar can do against some integrated front ends

I think a P2 with a top notch aerobar and an aero front brake would be hard to distinguish from any other top frame in the world if you just looked at the wind tunnel data. Not impossible, just hard =)

Thanks Jackmott!
I did read that article, as well as a lot of threads and white papers (Aeroweenie being an awesome amalgamation of data!) regarding the idea that the major difference aero wise between the 2nd gen SC and the 1st could be mostly the cockpit. I also read and agree with your opinion re the n.P2 with a top end cockpit such as the ventus/aduro/tririg/etc. in several other threads. I was just wondering if the 1st gen SC could match up to the n.P2 or be close enough, with the same cockpit/front aero brake for a high yaw angle slow guy.

Well the high end gen 1 SC comes with a nice cockpit and integrated brake, do you mean the lower end one?

Yeah I think the lower end gen 1 SC with a top aero bar and aero brake should fair nearly as well as anything.

Lower end one :). With a Ventus, it comes out to about $1,200 or so not including wheels. Super thanks again!

Maybe where you come from. Not so easy in the antipodes. AS far as I know we still haven’t had any UCI Legal 7-series in NZ, don’t know about Oz (where the OP is).
7 series in UCI trim would be the best speed/$ way to get sorted for serious TT.
