Hello, I am going for the new 505 SL. I ordered the non-integrated version which would take a little bit longer to deliver. So I decided to swap to the integrated version. Has anyone experience which integrated stem would fit? I prefer to have handlebar and stem separat for easier maintenance. Thank you for suggestions.
-
I would check the headset spec to make sure that it is 1.5 to 1.5, but my guess would be that they are using the ACR spec. In which case any semi-integrated stem should work. There are a few from name brands as well as Chinese manufacturers.
Can you share any details you have about the 505 SL? Any images? Information is sparse and when I asked about it Adam basically said "yes, its a thing" without much else.

Katie sent this photo and wrote: "The headset size is 1-1/2"* 1-1/2”ACR". As soon as the frame arrives I can provide photos. Should be in Germany in 10-20 days.The one attached also came from Katie@Carbonda. Right now I prefer the Specialized SL7 stem, not sure if it fits and if I need something more like another headset. I am not building up myself, a friend does the job. But I want to have everything ready. Right now I have a Carbonda 696. Very good gravel bike, just made the mistake to buy a size too big. Like many others... So now I'll try the 505SL.

Yes it is 1.5"/1.5"
T47 BB is the first available
UDH hanger
They provide CGB02 an integrated handlebar, flared by 6cm on the 40cm wide.
I'm looking forward to get and see the two I ordered.
One will be a mullet Force/XX and maybe the second too :D

Hi Carbonazza, do you think the Specialized SL7 stem would fit? Do I need anything else? Headset?

You'll need a 1.5" dust cover
Ritchey is doing one :

This one looks promising, but I never tried :

Hello Carbonazza, the photo shows the included headset and what seems to be a dust cover. On top of that I need the Ritchey cover? Sorry for asking again will be my first integrated stem...

Ask them, but this is probably the dust cover that is just designed for their handlebar, not the SL7 stem.
In your case you need a more generic part, such the Ritchey one.

Where do you find info on this frame? I can't find it on the Carbonda website.
-
Seems to be their new frame. Just write to carbonda and ask for it. Geo almost similar to the classic 505 (not on their hp either but can be googled) https://www.carbonda.com/road/gravel/cfr505.html Small changes were made and it is 200 g lighter. Mine is in custom for almost 3 weeks now....

I received my CFR505-SL this week, building up with Shimano GRX810 2x11. I've never been disappointed by Carbonda, and pretty happy with the quality on this one. They did forget to include my seatpost clamp, fortunately have a spare in my parts box. Will post more pictures later.
I've built up many frames up over the years, this is the first using an integrated handlebar (the CGB02).
Differences between CFR505-SL and CFR505:
- Headset size: 1-1/2"* 1-1/2”ACR (two 40 x 52 x 7mm: 45x45 deg bearings)
- Rotor size: 160/180 mm
- The rear brake cable exit was changed to the same design as CFR707
- The front derailleur cable routing was changed to the same design as FM1056
- Seat tube was changed to normal seat tube clamp design, same as CFR696
- Removed rack and fender mounts. Only keep two sets of water bottle cage mounts. (My frame has 3 with the downtube mount)
- Max tire size:700x42c / 650B*47c
- Max chainring: 50-34T / 42T
- T47 bottom bracket
- All mounts removed from fork. There are internal and external routing versions.
Build Notes:
- Rear caliper: flat mounts on the chain stay are 25mm thick, so if you're using Shimano calipers & SM-MA-R160D/D adapter, you will need 38mm long bolts (Shimano part Y8N208020)
- Headset bearings: Don't quite trust the quality of the supplied bearings, and considering what a PITA it will be to replace the them, I plan to order new Cane Creek or Enduro bearings for the build
- Front derailleur: cable uses housing from the shifter to to a plastic guide below the BB (pic attached). From there it's inner cable to the RD. You'll need around 1.4m of housing
- Rear derailleur: cable use housing from the shifter all the way back to the rear derailleur. I'm using a GRX810 RD, so I need to use the flexible Shimano OT-RS900 housing where the cable exits the frame to the RD. I'm using a Jagwire Double-Ended Housing Connector CHA062 to join the two cables. Note the Jagwire Pro cable kits (e.g. PCK500 ) also include the flexible cable section and double-ended connector.
- Get some Internal Housing Damper foam (6mm ID, 10mm OD) for the rear brake hose and shift cables to stop it rattling in the frame. I have some made by Jagwire (ZSK600), you'll need around 2-3m

Got my CFR505-SL built up yesterday with Shimano GRX810! Still waiting for my wheel parts, so using a spare wheelset with 32mm tires until they arrive.
Did the inaugural ride ride today which was cut short by a slipping seatpost >:(. Carbonda forgot to include my seatpost clamp but immediately sent me one, which is in the mail. I'm using an old spare clamp I had, but it has never gripped well, even if the seatpost is slathered in carbon paste.
First impressions are that the bike is very comfortable, absorbs a lot of vibration from the road. I ordered the 420x90mm integrated handlebar, and I have to say the top is kinda narrow. I would say get at least a 20mm wider bar that your normal bar width. The drops are wide and very comfortable.
-
@dogsbollocks what size is that?
-
It's a large - 564.1mm top tube, 594.6mm stack & 388mm reach

Hi, my 505SL arrived after 5 weeks in customs... Already build up, looks great! Only problem so far I choose FSA ACR headset, seems to work. I go for semi integrated to be flexible.
Which semi integrated stem will work with FSA? Right now I mounted a Specialized SL7 stem but the spacers do not fit...looks weird.
-
Bike is ready and fun to ride. Setting up was easy with the help of a friend, just stem/handlebar was tricky. I decided to go for semi integrated as I love my cheap PRO Discover handlebar. Like so many others I had to learn that FSA headsets only go with FSA stems, so I ditched my favorised Specialized stem. The first FSA ACR/SMR built quite high and although we cut the fork quite conservatively it was too short... So I went for the FSA ACR stem which works fine with 10 mm spacer which will maybe be reduced. Now I needed an integrated handlebar and was surprised that there are not too many on the market that fit. I wanted a little flare so went for Ritchey. All the others have too much flare or no flare or, like deda, 31.7 mm instead of 31.8. Seems like everyone has his own systems and makes sure nothing fits.... I am quite happy with the bike. Unfortunately I had to install lights as winter is coming and it gets dark early.

Great component choice which gives the bike a fast and clean look!
I'm curious about your ride impressions. Knowing it's a light frame and that the seat stays & the fork blades look thin, I'm wondered about the stiffness of this frame.
-
As the CFR505/SL is a gravel frame, I would assume it's designed to be compliant and absorb vibration. I've been riding mine for a few weeks now, definitely a very comfortable ride. If you're looking for a super stiff race bike, this would not be it.

Thank you for your feedback, good to know it's very compliant. For me, compliance and stiffness (lateral & torsional ) are separate properties. For sure in gravel the absorption of shocks is important, but since it is marked as a gravel race frame, I would like to know how it accelerates and behaves in corners.
Thanks

I think it likes corners ;-) I am 80 kilos and the 505sl isn't wobbly at all.

Isn't the cornering determined a lot from the rear length? If you check this the 505 (either the old or the SL) are quite short compared to other Gravel frames. How stable the steering is depends on the angle of the fork and the trail.. and the stem length. ;).. so you can tune this a bit. But the rear geometry is fixed.
Compared to a road bike the 505 is a bit less nervous. For the stiffness of the SL I am out.. cause I have the "old" one.

How do you protect the chainstay?

Put 25mm tires on a deep carbon wheelset, and you'll get a stiff bike feel with it 8)
Compliance comes from big tires, and the 27.2 seatpost(something you can't make stiffer ;D), the frame and fork are not flexing at all.
-
How do you protect the chainstay?
I bought a roll of helicopter tape on Amazon, and cut a kind of trapeze(20-25cm long, 25mm at the derailleur - 15mm at the BB) with rounded corners on all bikes I build
-
Does this frameset have mudguard mounts? I've read that it doesn't but unless my eyes are deceiving me I think I can just make one out on the RH dropout in one of the photos of jakonodi's bike.
-
No, there is no holes at the back of the BB.
And not on top of the fork.
But I use this now:

I do have the classic 505 and still..i use the quickly removable fenders. Very similar to the ones from Carbonazza, they are the SKS Speedrocker. They cover the wheels a bit more. They are very functional, I use my 505 as commuter bike and I ride at any wheather :)
-
Thanks both, but I need full coverage mudguards. Shame - this would be a great winter bike frame otherwise.
-
@dogsbollocks are you based in the UK? Also, what headset cover are you using? Is it a Carbonda supplied one?
-
I just stumbled across this thread. The frame and it's quality (plus good seller reputation!) is very tempting! ... if there wasn't the short distance between front axle and bb ... since I rode my current Velobuild GF001 in Norway on long and steep climbs I became allergic to toe overlap. This is one of the main reasons why I want a new frame...
P.S. I was also tempted to buy either the Lexon GFX or BXT 135 since they have enough room for my toes. But how very helpful this forum is which keeps me from buying junk from bad vendors.

Hi all
First of a couple of posts about my build of this bike.
I’ve bought the integrated frameset in XL painted RAL 5025 - metallic effect Pearl Gentian Blue. The frame has arrived and quality of manufacture and paint job is very high, even better than the already good 29er hardtail I bought from Carbonda last year.
I wasn’t sure whether I’d want offset or zero offset seatpost so bought both. And like a number of others looking at Carbonda’s integrated gravel bars, CGB02, ideally I’d have wanted a longer stem and narrower bar than they offer (80x400, 90x420, 90x440, 100x440). But I took a punt at their 44cm bars and 100mm stem version. And as someone else has observed, they actually feel narrower than their stated width, which for my preferences is a good thing. They feel stiff and the cable ports are well finished (and wide).
I’m halfway through building with the parts listed below. Will post pictures and conclusion when finished. For now, a word on the headset:
I wanted to replace the headset that came with the frame - mainly because I don’t trust the bearings (and with an integrated set up I didn’t want to be replacing them in a hurry…), but also because the FSA ACR headset cover looks neater than the Carbonda one. So I ordered the FSA ACR #55, which is compatible with the Carbonda bars (and spacers). Slightly problematic. The headset top cover works well with the bars, and looks better than the Carbonda one. And it is compatible with Carnonda’s top bearing compression ring (which as it happens looks like a better design than the FSA one). But the FSA bearings are a) 51.8 OD wheareas the Carbonda ones are 52 (which is the required size for the frame, the 51.8 bearings are a bit loose); b) the FSA bearings are 36/45 and the Carbonda ones are 45/45 (which makes no difference if you don’t mix and match race and compression ring); but c) the FSA bearings sit much lower in the frame and so (either) top cover rubs against the top of the headtube when tightened. So, I’ve gone and ordered a pair of Hambini MH-P16 bearings and plan to use these with the Carbonda compression ring, Carbonda crown race and FSA headset top cover. We’ll see.
Build list:
- SRAM Force XPLR 2023 1x (with Pass Quest 42T chainring)
- Ali X cheap ‘Carbon Fibre’ saddle. Now use this on all my bikes - cheap and comfortable, even on my hardtail
- ZTTO T47 bottom bracket. Looks ok, not ridden.
- two pairs of wheels: both rims supplied by Leon at Yuananbike - 24mm internal, 39mm depth tubeless hooked. One pair will be built 28/28 with Pillar Wing 20 straight pull on Goldix GDR310 hubs. Waiting on rims. Other pair being built 24/24 with Sapim CX Ray on Malcolm’s Borg hubs (The Cycle Clinic). Will put 33mm slicks on the 24/24 and Conti Terra Trails on the 28/28.
- ZTTO bottle cages.
Cheers
Ben

I didn't find it in the threat: Could anybody comment on frame and fork weight?
-
The pictures Wing sent me showed 980g and 400g unpainted. I think for XL but not sure. I didn’t weigh the frame/forks painted.
-
980? Dont Carbonda claim a 1200 weight? That is a big weight improvement.
