After a Niner RLT9 steel and a gravelificated BMC Alpenchallenge, I have just ordered the Carbonda cfr505. At least Carbonda calls it the cfr505. They're a front-end dealer for Flybike components, I heard.

To avoid the pain of going through customs in Belgium, I have found a very helpful retailer in Holland. The surplus of going through them, to me is well worth it. The headaches and surprises I have had with several sets of aliexpress rims so far... Better if going through XDB, but best to avoid completely.

The dealer in Holland is CycloCarb

He also changes their seatpost to another one which works a lot better without the slipping issue and suggest to get some real bearings instead of using those that come with the frame.
Just for kicks, I ordered the monocoque handlebars too, we'll see.

Folks with Carbonda orders, how long did it take from when you placed the order to delivery?
Frame send 2 weeks from order (as quoted) and 1 week to deliver.
Thank you! I'm so so excited for mine, hopefully it will be here before Thanksgiving

33 days from payment to dispatch, including custom painted frame and seatpost. The paint didn't work out the first time so they had to re-do it. Also, they didn't have stock of CFR696 back in May, but seem to be getting orders out faster now.

Hey Guys,

has anyone build something with a Mondince frameset?
It looks quite good for the money.

Like the look of the 3T Exploro but not the price so have gone for one of these,
Tiedace FM-CX039 TA of Aliexpress in the 30% off sale that started today, came in at £354 with all the discount codes i could apply.
http://www.haidelibikes.com/product/sho ... .php?id=41

Plan is run it 2x11 with SRAM Hydro brakes, customised to run Di2 shift levers and Ultegra Di2,
FSA K-Force cranks with Stronglight CT 2, 33, 49, chainrings. might seem a weird ring setup but i already had the 33ring and the 49 was cheap as its an odd size. Gonna use a Canyon copy one piece bar and stem unit and Chinese carbon saddle.

Not sure on the cassette specs yet. but i have bought / built some reasonable spec wheels for peanuts by scouring the web for sales,

For 650b MTB, a set of Progress XC1 with Vittoria tyres, they came in at £120 without discs and cassette,

700C for road, 24 hole Dati 6 hubs, laced to Pacenti SL25 rims with DT swiss Revolution / Competition spoke mix alloy nipples and Challenge Paris Roubaix 27mm tyres, these worked out at £170 for the lot, again minus discs and cassette.

And for road plus,

32 hole American classic hubs, laced to KOM SL 25 rims with DT swiss Revolution / Competition spoke mix alloy nipples and Pacenti Pari Moto 47mm tyres.

Sorry if the answer to this already lies somewhere in the thread already; I haven't been able to find it.

Is there an Open Mold version of the Open UP out there somewhere? I am talking about same geometry (including 420 mm chainstays), round 27.2 seatpost, internal cable routing, etc.? I have seen a couple offerings from Workswell and Carbonda, but those seem to have longer chainstays. I also found the one below with 420 mm chainstays, but it has a proprietary seatpost which is a no-go for me. So I am basically looking the same frame as below, but with a round seatpost instead. Help a brother out please :)

The same question for me. Has anyone out there an answer?

Hi, what is your impression of the clamp and the seatpost? Do you think it is stable and in a good quality and what about the frame in that area?

I’m hoping for under 8kg. The crank is supposed to be under 600g. I have a X11SL chain that weighs 250g with all links and Xpedo M Force 8 Ti pedals at 214g

It's probably too early to comment much about the seatpost clamp, because I haven't fixed the height or torqued the clamp assembly. I am still waiting for the crank and won't ride the bike for a couple more weeks probably. The clamp is just three triangular pieces, and if you'd like to see it in more detail I can pull it out and take a photo.

Thanks, but that‘s not necessary. I know that fixing from other bikes. I'm more interested in whether the saddle clamp is stable and does not break during the first ride.

Can you fix mudguards?

SRAM uses DOT fluid for the brakes while Shimano uses mineral oil. And my understanding is that you can't use both together as the seals may deteriorate when they come in contact with a fluid they're not designed for. Just using SRAM discs, with Shimano calipers and levers will be fine of course.

DutchMountains, you can kind off run a mixture,
I remove the Sram shift mechanism and brake lever from the brake body, and replace it with a modified Di2 shift lever with its electronics pack. The modified brake lever runs on the same pivots that the Sram brake lever ran on, and the Di2 electronics fit where the Sram mechanical shift system fitted.
I've modified about 5 systems this way some with disc brakes and some with HydroR rim brakes.
So the whole system that sees brake fluid is Sram so no fluid issues and you get Di2 shifting, You might ask why. Well i intially did this on 3 HydroR rim setups.
Then did other custom setups for disc versions, as several UK shops where selling the Sram stuff really cheap and wrecked or scuffed up Di2 levers often appear on Ebay.
My CX bike is Sram hydro levers operating Formula R1 callipers, and the Sram shift levers operate minature switches wired up to a Di2 climbing electronics module and an XT Di2 rear mech.

Heres a pic how its done.

That would be unfortunate if the clamp is not secure, to say the least. I will report back. There are front and rear fender mount points.
