Please.

all i want to see is power improvement.

At threshold?

. . or black but ideally white.

Or any carbon TT frameset with a 54 or 56 top tube really.

Zwift is a nice distraction due to its interactivity

It must be fun or it wouldn't make up 70% of my Strava feed!

I am not easily bored so solo riding outdoors or on the turbo has more appeal.

edit: seems that you should maybe do the 20s at 95-100% of FTP

Yes that's more how Coggan's guidance reads. I think that if you do them a bit too easy you get most of the benefit. A bit too hard and it's a different type of session and you get very little of the intended benefit (also too hard tends to put me in a hole for a while).

For me, if finishing both twenties is in any doubt then I'm doing the session too hard. If I have got it right then during the first twenty I am impatient and half-wheeling the PM. The second twenty then needs a fair bit of focus.

I think it's in the nature of this type of training that two or three watts too many can make a huge difference to RPE / ability to complete the session without a lot more whimpering than is optimal.

I am (tediously) evangelical about Coggan's threshold training. It made a big difference to my racing. Since I am always banging on about it but nobody ever listens / copies I assume the sessions do not suit most people.

That's the session, yes. Once or twice per week. Incremental improvement through the winter like Milo of Croton and his bull calf. Gain a watt or three per week. Week fifteen feels like the same effort as week 1.

But no FTP testing. The 2x20 is a weekly test. "Training is testing, testing is training". Innit.

Old hat now. Still seems very effective and I wouldn't expect to get fit without it.

Zwift sounds like a training nightmare to me.

A key benefit of the turbo compared to say Richmond Park or Regents Park is that there is zero chance of me being distracted by someone else or worse-still goaded into changing my effort.

I stare at the screen. I listen to the whine of the turbo. It's the least complicated, most calm hour of my week.

And Coggan's incremental threshold improvement's via 2x20s through the winter still works doesn't it? Seems to work fine.

Kingston-based tester and family cargo-bike rider.

Got three TT's I want to not be shit at this summer, mid-May, late-June, mid-August. I've always tried to peak for say a 3 or 4 week period when there's a bunch of stuff I want to be a bit less slow.

This is my recurring problem. I know absolutely what to do from November to April (well it's good enough anyway) but then it all goes to pot once racing starts. Too much tapering perhaps. Fitness falls away or fails to increase. The main thing is that the certainty of purpose goes out of what I'm doing. I drift. I hope you get some answers here so I can read them.

Has anybody got one of these? Sold by Velosa / Cabin or Covas Bike Store or Elite Wheels, all on Ali Express.
Carbon clincher disc wheel with 23mm wide rim. Freehub can be swapped to fixed. I'd include a link but Ali seems to be down.

It's just what I need. I currently race on a fixed wheel bike and would like a disc. Geared bike might follow later this year.

I have had very good experiences with purchases from China in the past, including a clincher disc wheel. It would just be nice to hear from someone who has got one of these hub swapping discs.

Thanks Dave. The bike is actually a nightmare to keep clean. Matte paint a silly choice.

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.

Worthy thread update!

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

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.

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

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.

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

He did. It would have.

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

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

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.

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

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.

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.

In a good way?

Why hasn't this appeared anywhere on this thread?

Haidelibicycle say they can supply with a fork drilled for brake.

BXT say they can't.

So it is, thank you. Looks ideal.

What is that frame please Lukas?
