Author Topic: Quick Pro GR:One - First one in the wild? build suggestions / hack to 2x  (Read 52402 times)

I didn’t plan to buy a bike at Eurobike.  8)

In fact, I was in Frankfurt for work and figured I’d swing by the show on Saturday. But as these stories tend to go—things escalated.

Wandering the halls, I came across the Carbonda booth (Carbonda Sports Equipment Co., Ltd.). Initially, I was drawn to their carbon road wheelset—the woven finish looked nice. While chatting with the team, they mentioned that everything at the booth was on sale. Apparently, they didn’t want to haul it back to China.

Their showpiece was a new AF 01 Gravel frame. But coming off a Cannondale CAAD12 (54) and more recently a Cube Cross Race C:62 (53), I was leaning toward something more race-oriented. The Cube has served me well but with limited tire clearance and a notably high bottom bracket, I was thinking about something with more clearance but still universal.

That’s when I noticed a Quick Pro GR:ONE frameset quietly sitting on a back shelf. I wasn’t too familiar with Carbonda at the time, but the Quick Pro branding rang a bell, and the frame’s finish caught my eye.

They also had a set of their Canwin GC50 carbon wheels on display (the GC60s had already been sold). The price of the wheelset? Surprisingly competitive.  I took a walk and gave myself some time to think.
A few quick geometry checks later, it looked like the Medium GR:ONE would fit me almost perfectly.

So I went for it. I justified the leap by telling myself I’d be one of the first to ride and report on the GR:ONE—and honestly, the price was still very competitive compared to retail. One quick PayPal transfer later, the Carbonda team began wrapping up the frame and wheels.


Frame, handlebar, wheelset and they even threw in the mounted tires, which I only realized later were already set up tubeless, sealant and valves included.

It all came together so quickly that just two hours after vaguely entertaining the idea of “maybe a new gravel frame”, I was walking through the halls grinning, with a new Gravel frame somewhat wrapped in bubblerwap an a lot of tape.


Now comes the fun part: the build.
I’m planning to transfer the Ultegra / GRX Di2 mix from my Cube. The catch? The GR:ONE is 1x only, and I’ve always preferred a 2x setup.
The Shimano team at the booth strongly advised against retrofitting a front derailleur… which of course just made me want to try it even more. So we’ll see how that unfolds.

If anyone’s curious about the geometry, I’ve already uploaded the GR:ONE to GeometryGeeks and added a comparison to my other bikes for reference. Their website and overall presence is just not good enough for their premium prices, but maybe that's something they can improve upon.

At the moment, the frame and wheels are still sitting in my car—no tools, no scale, no real way to check weight or inspect build quality in detail. That’ll have to wait until the weekend. First impressions are solid, but I’m curious to see how the carbon finish, tolerances, and internal routing hold up under closer scrutiny.

As for the Cube: I’m planning to rebuild it for a friend. Ideally, I’d like to go with a more budget-friendly groupset, possibly something non-Shimano.

So if anyone has recommendations, be it Sensah, Wheeltop, L-Twoo or something less mainstream, I’d love to hear your thoughts.
Feel free to drop me a message or comment.

Looks like you made a great deal — the frame looks super nice! With all the buzz around this brand, if it lives up to its reputation, the quality should definitely be there. Looking forward to seeing the final build, weight, and an in-depth inspection of the frame!

The topic of alternative groupsets has been widely discussed on the forum. From what I’ve gathered, they all seem pretty solid, but there are a lot of L-TWOO users who appear satisfied with their purchase. Also, check out Aliexpress for Shimano parts — you can sometimes find full groupsets for not much more than L-TWOO or other alternatives, which makes the relatively small price difference hard to ignore.

Is buying things at the show common?

Now I’m really pissed my work trip to Frankfurt is NEXT week instead of the original plan of being there last weeek/weekend.

jonathanf2

Wow you scored! Not many of us get to inspect our frames or wheels in-person, so it's awesome you got to buy equipment on the spot! I would have checked out some other booths and see what vendors are willing to sell!  ;D

Is buying things at the show common?

Depends on the show and what parts they are showing. But yes "trade fair deals" are quite common, especially if things are in production already or "production-ready" showpieces.
Slow on the climb. And everywhere else.

Wonderful paintjob!

The 18K wave is real or is painted?


How much did you cost the frameset?

There is no price on website...

Hey everyone,

Thanks for the interest and messages!

Yes, the 18K weave is real. I’ll get a few more detailed shots uploaded by tomorrow at the latest.

Admittedly, I’m feeling a bit guilty about storing the frame in my car in some random Frankfurt parking lot.

As for the paint job: contrary to what the Quick website says (they call it “iced/frosted”), the finish looks more like the dark color was applied via ceran wrap technique over the lighter base.

Price on the website is retail price ¥ 13600 ≈ $1900 US

I also picked up their integrated handlebar. They had both the gravel and road versions on display—mine is likely the Quick Zephyr SL, not the SSL.

Now the big question:
What’s your take on fitting a round aftermarket front derailleur clamp, like this one:


My idea: mount it with some sort of 3D-printed insert to fill the missing portion of the clamp interface, plus add frame protection under it to preserve the finish. The frame has plenty of tyre clearance, at least on the website.

Would love to hear if anyone has done something similar—or reasons why it might be a bad idea.

Maybe chainring clearance could be an issue….depends on what cranks/rings you are planning to install.
e.g. I am on a Dura Ace 9200 crank with 48/33 rings on my new Yoeleo Altera…needed some tiny spacers to clear the chainstay…but still was able to engage the safety pin on non drive side…

Trying to use a front derailleur clamp on a carbon frame is a sure way to destroy it. In contrast to aluminium frames, carbon frames are only strong in the direction in which the fibers are laid out. The force that you exert when clamping a derailleur clamp is directly opposite of where that tube has strength.

It's the same reason why you should always clamp your bike on the seat tube when putting it on a bike stand, and never on the frame itself.

You would need to bond the (carbon) derailleur clamp to the raw carbon of your seat tube instead of clamping it on if you want any chance of succeeding/having a safe setup. I even think that you would need to reinforce the whole are with some extra carbon to account for the extra forces that the front derailleur would exert on the seat tube during shifting.

I would also go with Serge's suggestion and use epoxy. Before applying anything, test the fit: mount your front derailleur (FD) to the hanger and check if it can be positioned correctly on the frame.

If the position is fine, mark the spot on the frame. Then lightly sand the area until you reach bare carbon. Test-fit again to confirm, and reapply your markings—measure twice, act once. Once you're confident everything aligns, apply the epoxy.

Also, make sure to sand the hanger where it will be bonded so you're working with bare metal rather than any paint or coating. A properly prepped surface on both parts is key to a strong bond.

On a side note: does this mean this frame does also doesn't have space to mount a chain guide?

Buying a new Quick Pro from Carbonda ...

Are Quick Pro part of FBA?

RDY

FBA = Flybike Asia.

I thought I'd read elsewhere that QuickPro were the new house brand (together with a couple of other minor stakeholders) for another unrelated OEM / ODM.  But maybe it was unfounded speculation.

Usually Carbonda / FBA don't show their kit on other brands' frames at shows.

Well it's a tough cookie you've decided on with this 2x stuff. I really wouldn't reccomend epoxying a hanger. There's a reason even non removable front hangers have always been riveted on carbon frames. Whatever you do, you need to reinforce the tube where you plan to mount the hanger. Strip the paint on that section and reinforce it with a couple layers of carbon weave. A semi decent carbon repair service could do it for you pretty easily

If you were brave, you could then rivet on the hanger or some threaded inserts, but going back to your original idea of a modified clamp and giving yourself playroom for locating the hanger is better.

Hey, here are my first impressions of the frame, along with photos:
https://imgur.com/a/0Xo5rf6

I really like the paint and overall finish. On closer inspection, there are some minor imperfections in the clear coat—not a big issue, but worth mentioning. The black metallic/silver areas have a glossy clear coat, while the carbon weave sections feature a matte or satin-matte finish, creating a nice visual contrast. The decals are also well done: white with a holographic effect when hit by light.


On the fork, the brake mounting points are embedded aluminum inserts, unlike the frame, which uses carbon mounts. Not sure why they didn’t opt for a full-carbon solution here

The frame comes with a UDH mount.

One detail that stood out is the different thread pitch used for the front and rear thru-axles:
   Front wheel: Ø12 × 121L × M12 (P1.5) × 17L
   Rear wheel: Ø12 × 172L × M12 (P1.0) × 16.5L

Handlebar is the SSL version, 400mm x 100mm.

Since the frame was a showpiece, a few parts are currently missing:
   Spacers for the handlebar
   Handlebar bolts and insert to fix the bar to the fork
   Top cap and steerer tube plug

One thing I’ve been asking myself: should you order an extra set of thru-axles while you’re already having something shipped?
Any other additional parts, that I might be missing?

Regarding the front derailleur:
Thanks for all the input and warnings. I’ve ordered a cheap carbon clamp-on mount and will test whether I can shim the seat tube—measuring approximately 29.6 mm at the front derailleur position—to fit a 31.8 mm mount using an aluminum sleeve.

Epoxying something directly onto a frame of this quality just doesn’t feel right. But this workaround, while not ideal either, has the advantage of being reversible—at least in theory.


PS: Is there a way to embed an Imgur gallery directly in the post for easier viewing?

Let me know if you’re interested in any additional photos or specific details—happy to share.

Put on a new Rival XPLR 13s...

Don't mess with front derailleur clamp and setup..
