Title: Carbonda Gravel CFR505 build
Post by: carbonazza on December 21, 2017, 03:49:49 PM
Finally !! After about a year of mental convolutions, I decided for this gravel frame:
http://www.carbonda.com/road/gravel/cfr505.html (http://www.carbonda.com/road/gravel/cfr505.html)

My contact at Carbonda was Hedy Lee.
Perfect communication, very professional and kind during the whole process.

I received the frame, fork, bar and seatpost today from Carbonda.
Along with a matching pair of ultra light rims from Peter( 29er hookless, 300g - 19mm inner width )
What a day !

Just a couple of screws to tighten and ready to ride !  ???

First impressions are great.
The frame looks of very high quality, outside as well as inside !

The objective is to have a winter training road bike, that can ride in the forest too.
Making the parts as interchangeable as possible between my 041 and my ultra posh Canyon Ultimate.

Looks like they did a good job on the fade..

What is the component build plan?

For the wheelset, the idea is to make them compatible as:
I will give a chance to D411CB/D412CB Novatec instead of my usual expensive and heavier Hope's.
And straight pull for the first time too with 28 Sapim CX rays.

Then for the transmission.
Beware it becomes frankly aristocratic  ::)

I did put a quarq powermeter on the roadbike this summer.
As a result, had a spare Sram Red crank that I will re-use here.
If everything is compatible as it seems, putting a single CX1 chainring on it.
Probably 38T like on the 041 or maybe 40T.

I should have gone for a road bike trip in the Alps this summer( I couldn't after all ).
But in that plan, I bought a couple of compact chainrings.
And a medium cage derailleur(wi-fli etap) and an 11-32 cassette.

Of this I will re-use the medium cage derailleur and buy a cheaper 11-32 cassette.
Keeping the Red cassette and rings for actual road mountain climbing, and able to swap rear derailleurs between my bikes.

All these re-uses "force" 8) me to go with the SRAM etap hydro levers and brakes here too.
That way I'll have a totally swappable, set of components between my bikes depending on the need or in case of failure.
I hesitated a long time with the SRAM Force 1x groupset, but went for the big plan.

Here is my secret hope:
SRAM will provide in the coming months/year a 12sp etap long cage rear derailleur and road cassettes.
That will be compatible with the existing shifters.
And at that point I will be able to use/swap almost everything on all my bikes.

Any updates?

Considering the CFR 505 myself and I'd like to see what your end result looks like. Off to a great start, though. The frame looks amazing!

Family vacations are currently preventing any progress 8)
However I’ll try to order the missing parts this week to get them when I’m back.

Everything but the chainring and brake discs are there.
I got even two Haribo bears bags from r2-bike.com (http://r2-bike.com)

Build time !!  :D
Hopefully nothing is missing, everything is compatible, and my spoke lengths are correct( these are my first straight pull wheels  ??? )

I think this frame just moved to the top of my list. Well, when I get around to building a CX bike that is.

Any chance of running an internally routed dropper on it? I know that sounds odd but it would be nice to lower it a bit while on rougher stuff without getting off of the bike.

... Any chance of running an internally routed dropper on it?

If you stick to BSA ;) you are probably out of luck, as the shells are usually closed.
You could still route it from the front derailleur exit hole if you go 1x or etap, for a semi internal routing.

But if you go for the BB86, there are holes in the BB space where you could route a cable from the front derailleur( 1x ), or both derailleurs entry(etap), fiddling over the BB to the seatpost.
However it is a 27.2mm, so not many options.

Haha, well played.

I can live with BB86 or BB92 shells as the GXP cranks still work  ;D. My daughters CS-406 frame I just got from Peter has the BB92 shell and that was open like you mentioned. I tried the OTSO Warakin and loved that bike. The durability of the stainless steel frame has some definite benefits but being lightweight isn't one of them. So I've been searching for a generic carbon frame with similar geometry and this one is pretty darn close. Some things are a little off but one calls for a 400mm axle to crown fork and the other calls for 385mm. That should make up for the HA difference. I guess I'm just looking for more of a road capable drop bar mountain bike than a trail capable road bike. If that makes sense.

It is built !

From a quick tour around the block, the first impressions are great.
Feels light, stiff, agile to turn and I love its ultra-flashy look compared to my other black bikes ;D

Some doubts or issue I had during the build:

For the ones who care about this: it weights just over 7.4kg as it is on the pictures, and feels very light when holding it and riding it  :D

WHOW !!! Awesome build !!!!!

And at the end, what did you spend at total ?

Can you please tell me the rim types ? Or a url to Peters shop ?

Probably about 2600€ but reusing a crank and rear derailleur I had already.
Probably around 3300€ otherwise.
A Force CX1 groupset would have been a quite cheaper option, but incompatible with my etap road bike.

The rims are http://xmcarbonspeed.com/Productinfo.asp?f=1472
Beware they are limited to 60psi/~4bar max.
I'm not sure I'll be able to reuse them on my road bike, as mountain climbing wheels because of that tire pressure limit.

That’s an awesome build! You must be stoked.

So they can make the frame with fewer cable routing holes?

Also, what about the hubs? Why did you choose Novatec hubs? Just curious on your choice over other options.

Stoked is the right term, yes totally!
I can't decide myself to ride it in the mud yet :D

So they can make the frame with fewer cable routing holes?
Yes some folks on the ridinggravel forum asked for not having mudguard screws, so I guess there is some flexibility available.

Also, what about the hubs? Why did you choose Novatec hubs? Just curious on your choice over other options.
I wanted to try a straight pull and light wheelset.
Then I saw these, relatively cheap for their weight, compared to other light brands.
Read about good and bad stories about Novatec hubs on the web, and decided to try.
They look very well built, we'll see how long they last.

Awesome looking bike Carbonazza, love the paint, whats the saddle your using? It looks very light and comfy.

Looks like some options for a dropper post.  Wonder if you can request no front mech mounting and holes.

Can we see tire clearance?  Would a 42 fit?

Thank you! Yes, I'm very happy of the paint. It looks even better live.
The saddle is a Gub model 1156, you can find it on Aliexpress for $45-$60 depending the seller and period of the year.
I was riding the same saddle shape before, but bare carbon.
Even if the padding is quite thin on the Gub, it makes a noticeable comfort difference.
Beware it remains a hard saddle.

The seatpost is a 27.2mm.

They may politely tell you it is not possible, but yes, you can request a no holes frame :)

For the tire clearance.
The tires at 4bar(60psi) are around 40mm width.
And there are about 9mm of clearance on each side of the tire, front and rear.

For the chainring, it is tight.
With a 40T, I can move a 2.5mm allen key between the frame and the ring, but not a 3mm.
I think Carbonda say on their web site a 42T will fit.

What's the total weight on this beast?

Looks fairly light.

I'd love to build up a sub-16lb gravel bike.

As MTB2223 pointed out, it weight 7.4kg or 16.3lbs. Not that far from your target.
Unless you mean 16lbs without pedals, in that case we're in ;)

You could shave grams with a lighter cassette and a lighter seatpost( I got the carbonda one ).
The final discs should be lighter too.
And I found a nut for the Hardlite axle, some grams less there. Now it is an Aliexpress e-thru axle.

I'll weight the definitive build.
