I have a fs831 frame which i want to sell.

Too much travel. There's a well priced LC FS947 that I'd be jumping at, but being realistic, I don't need more than 130mm travel. This FM1001 is perfect for my needs!

Despite the unfashionable-looking compact carbon rocker arm and upside down shock, I think the 1001/1002 is a more resilient frame than the 947 or most other comparable unbranded factory direct frames (or almost-direct, as in the case of Carbonda doing D2C with frames that I think Flybike is actually manufacturing).

The 947's had a couple of reports of cracked stays already, which is a little ominous for a frame that's only been available for about a year. And neither case looks like the rider was a heavyweight doing big jumps or anything. Barely more than JRA situations, from what I remember.

If my 1002 holds up well this year, I'll be sorely tempted to build a 1001 next winter for the 2023 dirt season. Sophisticated suspension systems like linkage driven swingarms and high pivot idler linkages are obviously tempting but it's so much easier to screw them up with a small oversight than it is with a four bar.

And these bikes have some of the best kinematics I've seen in a four bar, with the relatively manageable tradeoffs of low anti-rise (so some mild braking interference with suspension movement) and a regressive dip at the bottom of the travel so you'll need an air shock with good end stroke progression. I don't even think the latter is much of a factor on the 1001, because the dip mainly happens after 130mm of travel.

Could you link these reports or did you hear it from somewhere else? I've heard of the seat stays possibly cracking when removing a bolt, but that was fixed. Never heard of any other cracking issues.

I'm already late heading out for a fat bike ride but IIRC one was in the 947 thread here (didn't involve removing any bolts that I recall, happened on a ride I think) and the other was on one of the major general forums like Pinkbike or MTBR...the latter, probably.

If you look at the 947, its chainstays are noticeably thinner and shaped differently than Carbonda/Flybike's and the dropout area is proportionally much fatter. I remember noticing that imbalance in visual appearance of strength early on when I was considering buying one last year.

When I was doing internal routing on my 1002, I liked what I saw. Some carbon dust that should have been cleaned up at the factory, but nice wall thickness/shaping and solid seams. Smooth port areas that seemed to be part of the mold, rather than cut out after the fact as some are.

Dang must have missed that one, fingers crossed it wont happen to mine :-\

I mean, I don't intend to scaremonger. A couple of anecdotes don't really mean anything, that frame's been fairly widely built by individuals and by OEMs. I haven't heard about any of those OEMs jumping ship.

I also don't want to invite karma on my own build in overestimating it by comparison...I'm famously brutally rough on bikes, weigh -210lbs at the moment (hope to be a lot less by summer), and won't even have a single ride on my 1002 for weeks yet.

Those anecdotes were on my mind when I chose the 1002 in December though, so it seems worth keeping the discussion about them alive. Not least because it could eventually help 947 owners avoid the issue, if there really is one.

Just been out for my first ride on the carbonda 1001, really enjoyed it. It rides really well, climbs well and descends better than I thought it would. I'm running 140mm RS Lyrik and a 185x50mm shock for 120mm rear travel.

I also posted this in the 1002 thread but it should be the same on both frames and maybe someone in this thread will have suggestions:

Any advice on how to make sure these wide mouthed cable grommets between the front triangle and chainstays sit where they're supposed to and stay there? While running the internal routing they came out of place and it was almost impossible to get them to sit flush for some reason. I assembled the bike with them slightly imperfectly seated but now as I move the suspension to set up the shock (equalize the air chambers), they get yanked out of place.

I thought I had the two cables run more or less correctly, so I'm not sure disassembly and agonizing over the cables themselves would help anything. But I'm having a hell of a time pressing them back into place with any of the tools I have while the shock is disconnected and I have the linkage all the way compressed like this....and I worry that they'll just come back out once the suspension moves again.

I've been struggling with them long enough that the temptation to just rip them out and go without any is very strong, but then I'd be worried about dirt and water ingress....but frankly, even if they were working perfectly I'm not sure how much difference they'll make anyway since they don't create a very good seal even when you have the cables exactly straight on either side.

And I think mine are a little twisted in the front frame such that they want to exit through the middle of the opening rather than straight through the sides. That's not necessarily something I think I can reliably change even if I did my cable routing all over again. What the cables do that deep in the frame isn't easily visualized or controllable, even with a magnetic routing kit.

Just received my Carbonda fm1001 from Katie, looks great. I just took a quick pic right out of the box.

I had it painted by them, the color is purple/green chameleon. Total cost shipped to Colorado was $1154.

Just starting to build it up, but wondering about frame protection.

@Neb, where did you get your chainstay protector and downtube/bottom bracket protection? I'm really liking the way yours looks and fits.

Thanks!

I answered you in the other thread.

1150 shipped seems like a lot, what was the price breakdown?

Here is a quote I got. Debating on what I want to get.

750USD/pcs
15USD for headset
15USD for rear axle
190USD for shipping cost

Then others mentioned 5USD for rear hanger.

Then that leaves a little over 175 for paint job?

As for sizing. Any thoughts on 5'6" (168cm) tal with 29.5" inseam (75cm)? Geometry reminds me a lot of my Trance X. Same rear shock travel. I ride a medium in that but some days it feels too big for me. Might be the Standover and the seat tube length. I'm leaning toward a small on this frame FM1001.
