Hi guys i am building a tt burke and have all the parts apart form the frame any suggestions on good frames for tt bikes?
Thanks
One that fits you. Try measuring your inseam torso and so on. If trying to snag from classifieds this will at least give you whether you want long and low or high and tight.
Price?
New or used?

There are tons of good bikes out there. At a minimum you need to know how you fit on a bike (long/low, short/tall) plus a budget before anyone can recommend a frame. It makes no sense for people to recommend frames you can’t fit well on nor afford.
I’ve heard the Felt IA FRD is a decent rig

Thank you guys

Shiv TT probably has more major TT wins racked up than any other over the last few years.
Cervelo P5 is the fastest. Start there.

Having owned and raced both the Shiv TT and the P5, I recommend the Shiv TT … no contest. Many, considerations. Couldn’t say which one is faster than the other (though I’ve had consistently better race results on the Shiv TT). But the Shiv TT is at least a pound lighter, rides and handles better (same wheels/tires used on both bikes), and cruises silently because of the way the cables are run, whereas the P5 is a flippin’ rattle trap on anything but the smoothest roads. That bike drove me NUTS! Plus, if you have a low front-end setup, it’s very hard to achieve on the P5. The Shiv can be restrictive that way, too. But it’s better than the P5.
Be wary of reading wind tunnel data of the frames and base your decision on that… The fact is that the rider accounts for the vast majority of the drag and the position you can achieve on a given frame will hence have a much greater impact than the aerodynamics of the frame. In other words, you may be faster on a seemingly less aerodynamic frame than on the best super bike.
Start off with a bike fit and then purchase the most aerodynamic frame that fits YOU.
I agree with the advice to be wary of wind tunnel data. Remember that most of the yaw angles experienced in the US are 0 to 10 degrees. Anything above that is rare. Cervelo is the king of low yaw angles

This is funny. You say to beware of wind tunnel data, then you say “Cervelo is king of low yaw angles.” Let see you substantiate that without Cervelo’s wind tunnel data. If I’m on a 2% or greater downhill grade with low wind and smooth-as-glass pavement, I might pick the P5 over my Shiv TT. In any other situation, I’ll take the Shiv TT any day of the week.
I loved Cervelo up and through the P4. (I loved the P4 despite the funky rear brake. We don’t need no schtinkin’ brakes!) But with the P5, they departed from their historical geometry and screwed the bike up, in my view. In the real world, riding on hills and flats and good pavement and rotten pavement and everything in-between, the Shiv TT is the best TT bike I’ve ridden and I’ve had way more than a few.

It is kind of funny the way I wrote that. I was sourcing Quintanna Roo’s wind tunnel data, Felt’s tunnel data, and Cervelo’s own tunnel data. From -10 to 10 degrees yaw, the P5 is king. Granted, it is just tunnel data and we all know that wind conditions can change on race day. If you look at pure tunnel data, Cervelo wins, their is no disputing that. What I meant was on being wary of tunnel data, is to just look at the average wind yaw angles in the US and then compare to tunnel data. Since most wind is 0 to 10 degrees yaw, any company beating another above that yaw angle is really pointless
What about the P5 did you not like?

I got ya and you’re right. People DO need to be leery of wind tunnel data. But performance in the tunnel isn’t the entire story. I used to LOVE my cervelos. But they made a dramatic change in geometry with the P5 compared to prior models and that didn’t suit me well at all. I have short legs, a long torso and a low position – all ideal for the OLD Cervelo geometry. I tried to make the P5 work for me, but it just didn’t. Plus, it’s a heavy pig and it’s brutally stiff and harsh. For me, there’s nothing the P5 does that the Shiv TT doesn’t do better. But I could say the same thing about the P4 (were it not for the rear brake).

That makes sense. The geometry is definitely different. I have a 2011 P2 and love it. I would definitely buy a P5 if I had the money. That’s the beauty of these superbikes, they are all aerodynamically close to each other in the tunnel and really, you can’t go wrong with anyone one of them. Each one has the capability of being better than the other on race day depending on the conditions. The industry is at the point of marginal gains. I am a Cervelo fanboy because I love how they are an engineering powerhouse, and as an electrical engineer, I can relate to a company that is all about the numbers. I am, however, not blinded by my joy of Cervelo and can recognize that at the end of the day, the fastest bike is dependent on the fit for each person. A bad fit on a P5 will be slower than a great fit on a Shiv. I’m just thankful we have so many options.
