Velobuild GF-002

[coffeebreak]

Additionally, my frame came without the two "doors" in the down tube. Under the bottom bracket and next to head tube. Chris said they have been doing this since two years, but all the pictures I see of Gf-002 builts have those.

Anybody also received a frame without the doors? I'm wondering if this particular frame I received is just a lemon.

Thanks, appreciate any help.

Welcome to the forum. I have this frame. Is there a rubber grommet in the chain stay where cable exits? Mine has one. Try removing that.

I'm trying to picture the doors you mention. What would they be needed for? My GF002 did not come with any doors in those areas.

No rubber grommet, the bottleneck is rather in the middle of the chainstay at the narrowest part. Its a hard stop, like carbon or metall, but not rubber.

As for the doors, I think they'd be used for access to the tubes for cable routing etc. Not a deal breaker, but was wondering why there are two versions of the GF-002. On the shop website they are displayed on all the pictures.

I see now what you mean. In case you haven't, try routing it with the frame upside down.

I ended up inspecting the frame with an endoscope and I could clearly see the bottleneck and where the EW-SD50 plug was stuck. Impossible to get through there.

Ended up cutting the cable, pulling it through and then soldering it together. Not the most elegant solution, but it works (for now).

Hey Everyone,

I'm new to this forum, currently working on a built of the Velobuild GF-002.

I'm having extrem issues routing the Di2 cable (EW-SD50) through the right chainstay. The plug off the cable just doesn't fit through the narrowest part. A shifting housing can be pushed through with force. I've tried all the special tools for routing, but the plug just won't fit.

Anybody has experienced similar issues with the GF-002?

me too, no doors, I was informed by Chris after placing the order.......I wish to use the one next to the head tube for the rear brake compressionless cable housing...end up fitting hydro disk brake instead of mec/hydro.

Yes, I added 3 or 4 plastic BB spacers on the drive side and that did the trick. Initially I added one less because the small ring wasn't rubbing but didn't take into account flex when under load so remember to add an extra one if possible.

@hazzer19 and others: would you expect spacers also being needed for a 46/30 chainring combo on this frame? Interestingly, velobuild said that this setup would need a longer front derailleur (?)

Yes, with 46/30 you'll need a longer front derallieur hanger otherwise you'll not be able to set the derallieur correctly. I just realized this 2 days ago when I placed my 46/30 cranckset....Chris is sending me the longer derallieur hanger, waiting for it.

This forum is unbelievable! Thank you, I'll ask for the same.
Btw I find it interesting that although this is the exact same frame design as Carbonda696, Spcycle SP-G20, Ican X-Gravel, only velobuild so far has told me that there could be a problem with the FD.

I ended up having to use BB spacers on the drive side for mine. Found out the hard way and chewed up a bit of the BB area with the chain ring before spacers were installed. Ran 2x for a long time with the spacers and no issues, eventually and eneded up going 1x and love it so far.

I know this response is not directly answering the question but thought I'd add it in case its useful to someone..
I used 48-33 and it works at the bottom limit of the standard derailleur hanger.

Do I read this correct, that I'd need many more BB spacers for the Riro crankset?

Or are spacers in any way going to be needed, as @hazzer19 described? Setup is still going to be a 30-46t chainring combo with a dub bb.

Learning more every day

Did anyone mesure the frame triangle inner dimensions in size 56?
Planning on getting a full frame bikepacking bag, either off the rack or custom.
My frame will hopefully be on the way soon!

Seeing this now. I have size 56 frame, if you are still waiting for these dimensions I will let you know by tonight!

Thanks coffeebreak! I received in the meantime:

For future reference, in size 56:
1. The inner top tube length measures around 48-50cm (it’s bent at the head tube)
2. The inner seat tube length is about 44cm
3. The inner down tube is around 58cm

Just realized i never posted pics of the 2 GF002 i built. The orange is mine. I ghetto painted it myself.
Farsports wheels, hookless (so my fat ass can hit rocks tubeless without worrying about breaking the rim)
Conti Terra Speed 40C tubeless w sealant - nice, but wears out fast.
Sensah 2x11 mech. Horrendous FD. Wouldn't recommend Sensah, i built 4 bikes w Sensah 2x11 mech, had a RD die for no reason, and Sensah told me to eat a *ick. And the FD is trash.
Jagwire keb-sl brake housing.
I do not love the brakes now that i have ltwoo er9 hydraulic on my road bike. in fact i will not build another non hydraulic bike for myself (i'm 80-85kg though).
All frames are Medium.
I had a lot of fun with the bike last year, put 3.2k km on it, as well as quite a few hours on the trainer. This year it's in fact been by home trainer bike, and it's developed a bunch of creaks i need to diagnose (almost certainly my fault / sweat).
The road one is the VB 168 with gangster deep wheels (Farsports too). I find it helpful to see them by side to realize how different the geometry is.

It was my 1st gravel bike. I quickly then bought another road bike, because this absolutely does not feel like a do it all road bike. The geometry just doesn't work for me on the road (too high, too slack, doesnt feel good going down hairpins). The vast, vast, vast, vast majority of my riding is road. I kind of wish i had more occasions to ride gravel, because i did enjoy it. But i find myself going for the road bike all the time.

My buddy with the black one is a runner so he bought it mostly because he's a lawyer and wanted a pretty bike / FOMO. He's happy with it though, the bike is a head turner. He uses it as a road bike.
