Carbonda Gravel CFR505 build

[carbonazza]

Hello Sebastian,

Yes, very happy.

It is a 54.
With a relatively short 90mm stem.
The reach was already a bit too long for me (I'm 178cm, 89cm inseam).

I have planned a 170km ride in September, but for now, it fits me well, and never had any back or other pain when riding.

Amazing bike and love the color. Did you go on that long ride? How was it? Looking to build essentially the same bike but with Force Cx1 and a few other differences

Yes I finished it! 166km of gravel, with 2600m of elevation gain, the ride is called the Dirty Boar.
And happen every year, in between Belgium and Germany.
Everything went well, I didn't get any mechanical issue, not even a flat with the Maxxis Ramblers in tubeless.
My friend rides a Force CX1 and is very happy of it. The cassette has a better range compared to mine.
Good luck for your build, and do not hesitate to ask questions if needed.

Hey guys,

really a lot of useful information here! I am about to order an CFR505 aswell. @Carbonazza, how wide is your crank? I am searching for a crank for a 1x11  with 40t set up aswell.
Did you use the headset provided by carbonda? Is it any good? I think you mentioned the axles are not worth taking them...

Cheers
Chris

What do you mean by wide? The Q-factor?
It is on a BB92, with a SRAM Red crankset.

Did you use the headset provided by carbonda?

Yes. I'm using $10 headset on all my bikes. Just insure it is the compression plug model, not the starnut.

I think you mentioned the axles are not worth taking them...

This one on the rear: https://r2-bike.com/DT-SWISS-Thru-Axle-RW-RWS-12x142-mm-E-Thru

This one in front: https://r2-bike.com/ROCK-SHOX-Thru-Axle-Maxle-Stealth-Road-12x100-mm (well I use the 15mm version as my fork is 15).
You can buy any road 12x100, just insure the pitch of the thread is 1.5

After using my gravel frame as a road bike for a year, I gave it a proper upgrade few weeks ago

The transmission is the SRAM AXS Mullet: Eagle derailleur, cassette and chain. Force shifters.
It is a Garbaruk 46T chainring.
And Deckas discs.

The wheels based on Novatec 411/412 hubs, and ultralight 29er XC rims, CR-ray spokes are still fine.
And I got as well a new fork, for 12mm axles( I initially took a 15mm one, but it was making swapping wheels harder )

Carobonazza - can you tell me how thick the chainstay is?  I am trying to order flat mount bolts and don't know what length to get.  And does anybody know what diameter the flat mount bolts are?  I've got access to plenty of stainless metric bolts and might just use them instead of ordering bike specific ones.

[carbonazza]

The chainstay is 25mm.
If that helps you guess, they need a T25 key.

If you've got plenty, take an M4 or M5 it should be one of them if it is metric.
Sorry for the imprcision, I ride tomorrow morning, and it is already too late here in Belgium to start messing up with my caliper to measure it

@carbonanza, that's a pretty cool looking Garbaruk chainring. I've personally used the much cheaper Chinese Deckas and sort of in between (price-wise) Stone chainrings and wonder how the quality compare to these Russians (or Czech?) Garbaruk.

[carbonazza]

There wasn't that many options to fit with my Quarq when I was looking at it.
It seems they are quite known by motorbike fans.
Their first cassettes were quite fragile a couple of years ago.

The ring works smoothly with the Eagle chain.
I even did a crazy 600km ride this weekend with it, with a freshly waxed chain and no additional lube.
But it is only a couple of thousands km old, so a bit early to know about quality.

They seem to take the bicycle gear seriously, I'm confident it is a good choice and start to put their rings on bikes I build instead of Absolute Black that clearly went through the roof with their pricing.

They are Ukrainian that moved to Poland by the way

[tripleDot]

Agree with Absolute Black... absolutely too expensive. I've run over 2.5 thousand kilometers on my $8 Deckas chainring and it still looks like it can take another 10 thousand kilometers.

On the 54cm frame size do you have any issues with toe overlap when turning sharp?

On the 54cm frame size do you have any issues with toe overlap when turning sharp?

No, but it may depend on the position of your cleats on the shoe.
My shoe size is 43 or 9.5-10

At some point I tried to put them far back, and I had it.
But after a few scary moments, you get used to it, and avoid being in that situation by moving your pedal on the right side of the wheel.

Hi... Does anybody have an alternative e-mail to order a frame from Carbonda? Have had a hard time trying to contact them through their website. Thank you!
