Fixed Time Trial Bikes

Not necessarily, but this is just a visual wind tunnel

That's the only type of wind tunnel I have ever used. I used it for my TT position, tweaking until I had a similar position to decent testers (Laurence Harding, Tony Martin, Peter Tadros, Fabian Cancellara, Michael Rogers etc). Not quite as clear cut with a frame but I don't see why the same principal shouldn't apply vaguely.

My hunch is that my Chinese friend bought a proper TT frame, scanned it and tweaked a bit before bunging into production.

As Jorj has said, you're not going to get a wind-tunnel tested frame for less than £2k and I am looking to spend a lot less.

These frames at least look clean, without the sculpty stuff on the early PX bikes and others. I would be surprised if a wind tunnel test didn't prove they have got the basics right.

Haha, yup, @GideonPARANOID is correct.
Two days ago @cake posted on my thread that they have one coming up for sale, might be worth a PM, @quickerbybike, if you want one.

Thank you Lukas. They are very handsome bikes. Hard to get hold of though.

I think I am going the chinese route. I look forward to derision from the forum.

No derision, but I'm sure there'll be interest. What's the geo like?

75 and 72.5. Perfect for what I want. 51 has a 535 top tube.

They seem confident that a fork swap to one with drilling for brake is no problem. I am a bit sceptical. We'll see. I'll reveal all when I know.

Huge image now deleted. See haidelibike if you are interested. Mine is ordered.

Crappy picture of mine at the local club 10 HQ last week.

What frame is that?

Dolan Pursuit Champion

Thanks very much, wasn't sure if it was one of the old alu On-One/Planet X track frames.

They use the same seat tube/clamp/post. Maybe same far eastern manufacturer.

Interesting... have to admit didn't know of the Dolan Pursuit Champion. Reading your thread I admire the passion for something most people wouldn't look twice at, but in actual fact it is something special.

Thank you very much :-)
@cake, near the (current) end of the thread, has, or did have, one for sale recently, if you're shopping.

Probably shouldn't but am investigating - thanks. Shame my local 10 isn't really suited to fixed :(

I've finished my fixed gear TT bike just in time for dirty roads and cold weather. Really pleased with it. Not at all the old man's take-no-notice-of-me-I'm-only-racing-myself rig that I had in mind. aeroweenies changed my mind on the frame and the Diderot effect influenced the rest. China made it all possible within budget. £1146 built.

Photos here. A dull day and a lame photographer. Plenty of duplication. https://photos.app.goo.gl/CsTHXnKFULvmLLHW7

Worthy thread update!

Would look great with a Miche Pistard Air or Rotor Aero chainset :)

Love it!
How's the quality/fit and finish of the frame and included parts? What's the wedge seatpost clamp like?

I told him to get a Vision NS, but I think it would have broken the budget.

Good recommendation.

(In other words, I was given the same advice and followed it).

He did. It would have.

Thanks Lukas.

The carbon frame and fork seem very good. The headset fits snugly and I would expect that to be one of the things to not work on a shonky frame.

The seat clamp seems completely solid so far. I was not brave enough to use the 7.9Nm specified for a specialized transition but 5Nm seems solid.

The paint job is mostly very good but masking round the track ends was a tiny bit lax.

Track ends themselves are the low point. Two plates sandwich the carbon. The plates are too slender and have deformed a little. They are maybe 2mm. The plates are held in position with 12mm countersunk screws. The inner plate only is threaded. The threads protrude 1mm and foul the wheel axle/hub. I have replaced with 11mm screws which are impossible to get hold of (friend made them for me). I imagine that's why they chose 12mm (easy to obtain).

Also the bolts to push the wheel back were cheap. One was bent. The knurled locknut was very rough on the threads. Cheap parts. I have replaced.

Lastly the above bolts are not level. They are parellel to each other but angle slightly upwards within the slot.

I'm really happy with it. The quality is not what you would expect on a Time.

Thank you! Just too much money I'm afraid. This was supposed to be a simple bike. Frame and wheels have gone a bit off brief but I didn't want to keep upgrading parts.

Sounds decent enough! Glad you're happy with it. As usual with a lot of unbranded Chinese stuff; nothing a little DIY can't resolve.

I've now ridden it hard for 50k on less-than-perfect Surrey roads, including at 55km/h.
No seat-post slippage. No headset rattling. No BB shell issues. No broken fork! Frame, bars, wheels all seem excellent. Feels fast. Not too unforgiving either. Very happy.

There, I've taken some risks for you all. Buy with (more) confidence.

Looks fantastic in that colour top work, which bars are those?
