Carbon gravel frame for 29x2,2 or 29x2,4 tires

[ains]

Hello,

Had anybody seen chinese carbon gravel frameset for 29x2,2 or 29x2,4 tires on AliExpress?

I would recommend to look at a hardtail 29er mtb frame and just put a dropbar on it if you're looking at that much tire clearance.

I am 168 sm height so mtb frame of this small size with rigid mtb fork and a dropbar will look like a centaur (see attached photos)

There are many carbon gravel bikes that fit wide mtb tires and don't look like centaur One good example is Storm Makai - https://stormsports.nl/en/products/storm-makai-beachbike-gravelbike  But they are  a bit expensive

Hope guys from Ali Express will make gravel frames for mtb tires someday too.

Depending on the frame, radial XC tires might allow wider but lower tires on gravel frames-really want to see the bicycle rolling resistance testing on these as well.

That is an interesting info. Will be checking news about those tires.

By the way, just made a drawing of the Dropbar MTB with rigid fork in size XS using BXT-MTB-066 frame. This frame in size XS has almost the same reach as my Carbonda CFR505 gravel bike in size M. But the result is looking really bad

I think it is better to wait until guys from AliExpress will make carbon gravel frame for wide MTB tires than to ride strange looking MTB Dropbar bicycle

Good news! Guys from Seraph and Spcycle from AliExpress wrote me that they will develop a new gravel frame for 700x55 tires in 2026! 700x55 is the same as 29x2.1, so it will be a good option for those who want to ride gravel bike on 29x2.1 Schwalbe Thunder Burt tires. Hope those frames will have affordable prices

Sounds good 👍😊

I was almost getting the BXT -056 for this purpose
, but maybe I will wait a little longer

BXT-MTB-056 frame has a long MTB reach. You will need to use very small MTB stem or use frame one or two sizes smaller if you want to install a dropbar. Also the stack of this frame is very high too. I've compared geometry of plenty of AliExpress MTB frames with my Carbonda CFR505 gravel frameset in size M on bikeinsights.com . BXT-MTB-066 frame in size XS was the only one that had almost the same reach as Carbonda CFR505 in size M. But the dropbar build even of this frame looks very weird. I think BXT-MTB-056 with dropbar will look much more weird 

[Jarkko2410]

Yes I know it has longer reach, than my other bikes .
I would have used 60mm stem instead of normal 90 to compensate that difference.
Also the stack is higher.. yes, but this one was going to be adventure bike, so little
More relaxed position would not be harmful.
Many of the current incoming gravel bikes also comes today with longer
Reach, in my case : they used to be 370-380mm and are now close to 400 in some
Bikes. Idea behind ... Use shorter stem to get right behavior.

I think this looks good..
And with drob bars maybe even better

[Jarkko2410]

Btw.. do we have any other information about the coming frame ?

It looks really not bad. I like that the space between the down tube and the front tire is not so huge like on BXT-MTB-066 frame. It is interesting if this rigid fork is 29, 27,5 or gravel size?

No more info unfortunately, but there is a guy from Spcycle on this forum. Will try to ask him.

[Jarkko2410]

29" fork at least looks like it
