They shipped mine today, on last day of the Ali shipping window.

Exciting to have something to get the testing kit back out for. Been mothballed for a bit. I'll put the GP5000 TdF TT tires on it.

Now need to get rid of the "error 404, legs not found" part of the TT problem.

That's the new rim shape. Numbers pretty impressive on the new 6560's, but the older ones were only 26mm wide so it may be a little be skewed.

Versus: gotta swap tires to be fair but you get idea

Nice, I’m having a hard time seeing the tire interaction in that last picture. But the one on the “Princeton” is perfect

The “aero moulding” on the gp5000 TT TdF also seems like it’s in an intentional different spot versus a normal gp5000. I wonder of there is magic there.

I feel the PCW idea is to optimize the “not a front disc” rule of open area with the big trispokes. Like having a front disc without all the issues one would bring.

Hopefully the new GP5TT’s are the same as the TDF special. I’ve got a pair of those right now. I also have some of the new VeloFlex Record 25 clinchers. BRR kind of did the 23 dirty using a 100g butyl tube. The tube weighs almost as much as the tire (125g). The original natural rubber one was fastest of all. Luckily I’ve got 3 of those but are reserved for track racing when it counts (natz and worlds)

Now just need someone to combine these deep spokes with a 100mm rim profile and a Revolver Troika brake rotor fairing

Has anyone here done aero testing on these wheels?

Have you tested GP5000 TT with "Troika"?

That will be the test, I just didn’t swap the gp5000 tt onto it yet so it’s a fair test. Troika rep vs PCW rep.

The rim width of both for tire interaction is about identical.

Disc or rim brake?

I'm waiting my "Troika"...

I'm still rim on a Trinity.

I've enough invested in the bike that I don't care to go disc anytime soon. Riding even my road bike I don't feel the need. Cyclocross and going disc brake made a lot of sense and helped a ton in wet/mud. But I'm not routinely on the brakes long enough or hard enough to justify it on the TT bike. Also I don't really ride road in the rain. If a TT is in the rain you're still almost never on the brakes for where I live.

Would love some decent, inexpensive US-made trispokes. Recommendations on models and where to look?

It's probably hard to find both a US-made and inexpensive tri-spoke. I'd be surprised if you could find any made in the US, actually. Dimond/Red Crown sells one but I'm not sure where it's made or if it's open vs. closed mold.

Maybe a 90's DuPont/Specialized trispoke. Or a doctor triathlete looking for the newest upgrade. I don't think inexpensive carbon and US made apply anymore if you want something new.

Light bicycle just released their new trispoke

I expected it to cost more after they priced their disc at almost $1500. If I was speccing that out I'd go chosen hubs and a grooved brake track for rim. $615 is pretty reasonable considering I haven't seen a similarly designed one on Aliexpress yet. And the claimed weight is much lower than the trispoke I'm running now.

I'm quite surprised as well!

Think I'll pick this up. Hoping I can find a 21 int disc in the classifieds soon

After doing ~ 200 runs of aero testing this year so far in 2024 I can tell you calf sleeves do not work for everyone. I've seen as much as a 10+w penalty. The right calf sleeves, when they work, can be a huge help. The wrong ones can be a huge penalty, 2+ min/90km. (i've tested 2 HUUB models, WYNN, and 1 or 2 others I can't remember - no consensus on which was the fastest....or slowest.)

I'd erase the red on the BTS as an absolute as well.

I've tested the brand Emotion out of AUS this year on the roads on a few athletes. Wasn't the fastest option for all of them but was for iirc ~ 60-70% of them. Reasonable as well, ~ $650AUD.

All their wheels are reasonably priced. If I was was still racing I'd ponder bringing a 3 spoke and disc wheel back to the US to race on.

Thank you for all the insights you have provided in this thread!

Have you found any similarities between the profile that tested daster with a tri-spoke? Perhaps faster / slower depending on the width of the fork or how close the wheel was to the downtube?

This post reminded me that I never got the wheel I ordered towards the end of November. I just checked the order page for it and it says "processing" . . . wonder if I'll get this newer one or if I'll get a wheel at all?!

Have you seen the Carbonal disc (22mm ID)?

I'm actually more surprised that the 88mm deep front wheels that are just below them are only $256! That's crazy low.
Interesting that it's 88-is this a copy off of the Premier wheels which are rated really well?
