I have a question:
Anyone knows why initial post mentioned T700/T800 carbon, but official site is Toray M40J T800 / T1100 now?

If i remember correctly, originally there were 2 versions listed on the page regular and super light

Mine fits just right. You can buy ball end hex bits for hard to reach areas. I usually use those on brake mounts and shifter bolts
Mine has similar shape and when I try to torque it up to spec, it slips - the angle is not close enough to 90 degree. And it scratches the seatpost too... Anyway, it's not that much of a trouble :)

Ordered: Geometry looks pretty progressive for 535 frame: reach is long - 399, but stack is not too high. 0-offset is available also.

Well done. Much, much wiser choice than Ali frame. I'm yet to see anyone hating on their Speeder frame.

Thank you. The main reason for the frame - pretty interesting geometry. But the stiffness is always the question for the price range - would be interesting to check.

I’m also not hating on my 48d and it has been great but it’s very stiff.
In the end I was much more satisfied with it than my giant propel. But that may also be due to the fact that I expected a bit more from a frameset that cost 3x more.

Only drawback could’ve been communication with Justin

I did about 13000km on mine and counting. Love the frame
I completely rebuilt it for this season: new wheels, cockpit, 0 offset seatpost, new ltwoo er9 v3 with 4piston calipers, galfer rotors, new cassette, chainrings. Weight with pedals, bottle cages, computer and varia mounts is exactly 7kg
I also recently installed 34c vittoria corsa tires. They measure just under 34mm on my 24mm internal rims and there's plenty of room left. You can probably put 38 in the front. In the rear there's still 4mm of clearance with the 34.

Looking to get this and wondering about geometry. Is their size 450 closer to a size 48 in Cannondale? I plugged them into Bike Insights and this looks like a slightly more aggressive Supersix Evo frame in my size of 48. Would this be right? I'm only 5'5 so can't really go to any smaller size.

Also how do you get started with ordering? Click on the contact button on the website or email justin?

You are right. And it's pretty much the same as the 2026 model.

I started from the inqury on their website and continued via e-mail with Justin.

Question about geometry as I am considering this frame.  I am 175cms, 80cms in seam. Currently ride a Medium Giant TCR with 5mm spacer, 110mm stem.  Would a size 480 or 510 be more suited for me?

Hi 174/83 seam here and I would go with 480.
Currently riding on 384mm+531mm

I was in the same boat as you, exactly same height and same in seam, I went with the 510 because I wanted to have a slammed cockpit
Looking back if I were to buy again I think I would go for the 480 with a riser handlebar.

If you want you can look at my photos to have an idea of how tall the seat post would be for you on a 510.

During the internal inspection, Sorry - forgot to take photos, so just the text:


To make it clearer - these are very very minor flaws, the mechanic said that most well-known brands have much more major issues

- Definitely not a single shape mold because the back triangle is glued on, but that's completely normal
- The main thing that the mechanic noticed is that the carbon sleeve under the bearings is not the same width everywhere - in the front part it is 1/2 smaller than in the back, but this is only noticeable visually, after assembly I did not notice anything
- In the upper tube there are two glued patches at a distance of ~5 cm from the headset - it is difficult to say why they are needed, perhaps just for better stiffness - so it might be even good


- The frame is clean inside and looks good.

- I can confirm that the frame feels good in my hands, it is stiffer than my Yoeleo R6, maybe like the Supersix Evo Hmod, or maybe better.

 In general, I am very satisfied with the frame. If there is anything new, I will update the post.

This frame looks a while lot like the Twitter gravel v3 in this image
