Title: Tagoola road frame: development log #1
Post by: Ada on October 14, 2026, 01:11:58 AM
As many of you know, we've been making carbon wheels for quite a while. Thank you for the support. It's what let us keep going in an industry we love.

We ride every week, and over the years we've ridden a lot of frames. At some point we got curious: could we build one ourselves?

So we're making a road frame, and we'll share how it goes along the way. The first prototype is being prepared. When we have something real to show, we'll update this thread.

We'd love to hear from you.

Usually 1st frame size is 54, sometimes 56.
For sizes 56 and above (and maybe even 54), frame must clear Contingental GP5000 35C on modern rim (measures 40-41mm). Whether smaller sizes need 35C, maybe a vote?
For sizes 56 and above there should be more stack than a Specialized SL9 (probably at least 20mm more in 56 (more?), and more for bigger sizes). This is something it would be interesting to have a vote on.
Steep seat tube angles are important, zero offset seat posts as well (modern / progressive geometry).
Aero features are important (a narrow head tube, and features no less aero looking than an SL9). Aero features at the back do not really matter, but a narrow / aero seatpost / seat tube is important.
Comfort is important, stiffness too, weight too.
BB probably needs to be T47 because a lot of cranksets have a DUB axle now and that doesnt work with BB86.

Which sizes would you want first?
Don't care as long as small size are available at some point

What matters most to you in a frame?

What tire width do you usually run on the road?
Smaller I run is a 30mm GP 5000 S TR, biggest is 35mm GP 5000 S TR. So I think 40WAM tire clearance is expected on a current road frame

What would you most like to see in the next update: photos, weight, or test results?
Photos, geometry chart.

First of all, I'd like to see some originality in the frame shapes....so many frames coming out lately are basically copies of the SL9... I really hope *not* to see another SL9 clone!

Personally, regarding the design, I'd like something along the lines of the Factor Elara (without the "big" fork), Cervélo Aspero 5, Quick Pro Er:One, Merida Reacto, or Canyon Endurace CFR... perhaps paired with a riser handlebar (Tavelo style, not Y1rs).

Another very important aspect for me is the attention paid to graphics (also the logo's name and font) and colors...a comprehensive approach to the graphic design and color scheme can really elevate the frame and give it a "premium" look.

I think UCI certification would be highly appreciated.

I like the SL8/SL9 geometries, though perhaps you could be a bit bolder with a steeper seat tube angle (STA) and slightly longer reach.

As for sizes, I'd prioritize the most popular ones: from 52 to 56/58.

A reasonable price is, of course, always appreciated.

Good luck with the project!

Which sizes would you want first?
I am size 56/58, but I can wait for my size as long as I can buy it eventually.

What matters most to you in a frame?
In the medium-to-long run, I will be buying a road bike frame with wider clearance. Think LongTeng's LTK-266-D-SL, but with more progressive geometry, similarly lightweight, and potentially more aero. If the frame ticks these boxes, the price is not my major concern as long as it remains below what some of the established Chinese road frame brands charge.

What tire width do you usually run on the road?
I am currently running 28mm (30mm WAM) tires, but the whole reason I am in the market for a new frame is wider tire clearance. I've had an itch for gravel lately, so I would like to get something that is optimized for the road, and keep a second wheelset with ~40mm WAM for when I want to do gravel.

What would you most like to see in the next update: photos, weight, or test results?
Everythingggg.

Which sizes would you want first?
54 and 56

What matters most to you in a frame?[
Lighteeight, Progresive geometry, steep seat tube angle, some aero, stiff frame where necessary, and comfortable where needed.

What tire width do you usually run on the road?
I run 32mm tyres but for my next frame I want 35-38 wam for future proofnes

What would you most like to see in the next update
Photos, specifications, geometry chart, weights... Everything  ;)

Which sizes would you want first?
52 / 54, but as long as other sizes dont take too much time, I dont care if I have to wait a little bit longer

What matters most to you in a frame?
The looks! If my eyes dont like it, I wont buy it -> That its not the next 98 % copy of a western frame (like SL8/9) -> aero but not all out -> geometry -> weight -> cost
But everything is important. For the looks: I like riser Bars, especially when its in a line with the top-tube (without spacer) like Y1RS or Cervelo S5

What tire width do you usually run on the road?
32 C

What would you most like to see in the next update: photos, weight, or test results?
photos -> geometry -> weight

Which sizes would you want first?
I mostly don't care but size XS or S.

What matters most to you in a frame?
A geometry with a very long reach and low stack combined with a steep seat tube angle and adequately long front center. Something similar to Ridley Noah Fast 3.0 or Ridley Falcn RS 2.0 and I wouldn't mind something even longer so I don't have to use a 160 mm stem.

What tire width do you usually run on the road?
28 mm.

What would you most like to see in the next update: photos, weight, or test results?
Geometry and photos.

Personally I'm looking for a 76° STA and a lot of reach. Probably 420 reach and 540 stack in my size. I'd compromise on a lot of things if a bike has good geometry. I won't compromise on geometry no matter how good the rest of it is.

Geometry is the key for me as well, everything else doesn't really matter all that much.

I'm tall and need a size XL frame, but that obviously won't happen at the start. Anyway, something like the Ridley Falcn RS 2.0 would be great: around 450 reach, 570-580 stack, steep STA of 75-76 in even the larger sizes (none of that "size XL is basically an endurance frame with 72° STA" nonsense), and the possibility of an offset seatpost (I personally don't need as forward a position as many people like, but I still want a ton of reach, so a setback seatpost would be a great compromise). And please, none of that high stack nonsense! It's been a nightmare this past year with every single Chinese brand pushing for a high stack frame. I can't run an integrated handlebar on something with 620 stack, I'll need a very negative stem for that. Whereas a low stack bike is perfect because then everybody who wants extra stack can just get one of those shiny new riser handlebars.

As for other points, I don't see the point of using big tyres on the roads we have here, but I guess having room for at least 35mm WAM tyres is what most people want (I'm okay with 30mm WAM).

This sounds exactly like me. 450 reach, steep STA of 75-76, I would say stack of up to 590 is ok. Frame lines wise, I think both out and out full on aero bike and race-y lighter aero bike are fine. No need for too skinny shapes and completely weight weenie focus.
