Neither are ideal, in my opinion. The BMC seems like a converted road TT frame and has a pretty low bottom bracket, and feedback I've heard on the Cervelo is that it's one of the least stiff carbon track frames on the market. It's designed as a pursuit bike. On my the other hand, either will work fine for a non-world class rider.

I got $10 that says that OP ignores everything we've written and he buys the "coolest" looking pursuit bike they can afford.








...and sells it within a year (doesn't matter if he sticks with the sport or not, same result).

That’s not true, I’m no searching the coolest bike. I earned a non expected money and I’m trying to do a good purchase.

1.- Dolan, Felt and Fuji are difficult to find here and now with the Covid is almost impossible. I tried at least in 15 stores.

2.- Steel frames and Dixie Flyers commented here are not available in Europe

I have the trackmachine 02 because it was the only option 2 years ago, I tried with other brands and it was impossible.

T4 and TR01 are the only frames I found ready to ship to spain for less than 3000$ (R96, Argon, Pinarello, Koga... are too expensive)

I made a research and I found the following info and I think both are enough good for me:

T4:
Lasse Norman Hansen 1.03 London 2012 Kilo
Jonny Wale (HUUB Wattbike) 1.00 Kilo
Switzerland 3,5x TP
https://www.velonews.com/gear/road-g...t4-track-bike/

TR01:
Stefan Kung 4.14 IP
Switzerland TP 3.56.x
Gael Suter 12.8 Flying lap
Rohan Dennis Hour Record

I asked to some people in my local velodrome and they all are agree that both are better than the DF4(said by an OG medalist)

So after 2 weeks I thank you all your opinions and messages, I really appreciate them.
I tried to follow your advises but it was no always possible. In terms of sport, here we don’t have the same variety of products as in the USA or France/Belgium/Netherlands because there is no many amateur sport.
I sent no less than 30-40 emails to different stores searching here mentioned frames.
So I think that statement is not fair and I was asking a last opinion about those two frames.

thank you all

You could get TR01 plus Ribble Eliminator AL as an unexpected substitute of T4 for under 500 Euro, international shipping included.


Eliminator appears as a twin of T4 at least in terms of geometry (Argon 18 Pro has very close geometry, too). It has HT and ST that are a few centimetres longer. Just compare the relevant sizes at Bikegeo.net. Thus only the stiffness of the aluminium would remain unknown before testing.

I guess you've decided against the Dolan anyhow (totally happy with mine), but I find it hard to understand why Dolan wouldn't ship to you.

Some sizes are not available on the Dolan Web and the only size I found available for me in Spain is only 190$ cheaper than the BMC.

Well if those are the only choices, I'd go with the Cervelo. At least it's a track bike, the BMC looks to be a converted road bike. In over 10 years of racing in two countries I've never seen one in person. Cervelos are pretty well represented.

Apart from it's limitations in rear disc compatibility it's a very good frame, maybe not as stiff as the dolan but miles better than the BMC (which only people sponsored by by BMC ever really used)

Again OP should really just stick with his current frame until he can really describe proper and actual deficiencies, people have gone far faster on significantly less stiff bikes and it's definitely not holding back any beginners. Even bikes like this went sub 10 in the 200m time trial

Duratec is a Czech frame maker that may suit. Mine is custom and a rather large 63cm top tube. It’s a whole lot stiffer than the carbon frame that it replaced. Hydro formed tubes allow them to produce a really stiff frame and the bike handles like a dream on the boards

Argon 18 Electron C Frameset; 2000 GB Pounds; Stack/Reach (M): 515/418mm; weight (M): 2175g; max tyre clearance: 22mm.

A properly fitting, adequately stiff steel bike with:

• Modern bars
• Quality cranks
• Quality pedals
• "808"-style wheels or disc + "808"

Would be "fast enough" to take any rider right up to the Elite National ranks. Seriously.

Aerodynamic qualities of frames are the lowest bang-for-the-buck on the $/gains scale in cycling. Fit is most important.

What does a modern, fast, steel frame look like?

I was just as fast on that as I was on this:

Don't get me wrong, frames can be sexy has hell and great to admire...but it's the size, geometry, and stiffness (relative to you) that matters...assuming that there aren't any malfunctions like slipping aero seatposts or tilting seat binders.

This is why people are saying that a steel or aluminum frame that fits is the best way to go. Carbon fancy frames are a luxry, not a requirement to go fast.
