Carbonda Gravel Carbon frame CFR707
Colt__Seavers:
Hi folks,
BIG NEWS! After Carbonda sold the CFR505 to Thesis, they were working on a new gravel frame set. It seems to be finished now. It's code name is CFR707 (FM1186 is the flybike name)
Common sizes will be available very soon. The uncommon sizes like XXL will be available at the end of this year most likely.
The frame set is like a combination of 505 and 696. It has a more appealing design like the 505 with its lower seat stays and the big tire clearance like the 696. Its wheelbase is pretty large to make room for big tires, so it's not like the 505 with its pretty short WB. So right now Carbonda is not offering road based / short WB / low stack gravel frame as a 505 successor, which might be a downside for some of you. Still, this new frame will be the right fit for a lot of you guys.
I like the sleek integrated seat post clamp and the 505 front end and seat stays. And I like the big tire clearance. If you want to run 700c 32mm on it, it might look odd with that big space between rear tire and seat tube.
Also the very high stack values are appealing. Top tube length is a little longer than the 505, but could be compensated by shorter stem.
Here are two pictures with 700c road wheel set, the frame drawing and the geometry sheet.
also check out the riding gravel thread, this forum get's a lot of attention.

I've built quite a few 505, as a versatile bike.
You can use on road, or gravel, just by swapping wheels.
It has very good handling and is looking great on both.
There are multiple things that surprise or sadden me here:
The BB86, they were offering the 505 in BB386
The chainstay length, compared to the geo drawing, don't you think they did put 650b wheels for the picture? The gap between the seat tube and tire is so huge.
The 30,9mm seat tube will be harsher than a 27.2.
For more dropper options? Oh my...
The headtube is not the usual tapered, but two 52mm holes, is this for full internal routing?
And I'm not particularly fond on the moustache look of the seatstays connection.

Yeah same thought here too.
I just got the info that it will have BSA. Which doesn't match the pictures and drawing. Still have to confirm that.
I assume a lot of things might change until it's available for pre-order at the end of September
There will be two version for cabling they say.
Let's see what changes and what the future brings
RDY:
Chunky joins seem to be increasingly popular on dropped straight (rather than noodley) seatstays, both with the big brands and the Chinese (LightCarbon & TanTan Gravel).... however that one looks bizarre, and very ungainly and ugly.
Personally I like the option for fully integrated, though I hope it comes with an option for just stem rather than full integrated 'cockpit', with a few options for angle and reach, and provision for spacers rather than solely zero stack.
I'm assuming the frame design is 'native' to BB86 and others will be retrofit. Or maybe it's just the proto.
30.9mm is a bizarre choice. This is hardly the most progressive geometry on a Chinese gravel bike ... so presumably won't really be in the running for dropper builds anyway.
I'm still interested in those new Workswell frames, if I ever see any feedback.
