Hi all,

I need some help since I want to get prepared for when my frame arrives - size 54:

What is the frame thickness at the rear break caliper, or what ist the correct length of the Brake caliper mounting bolt C? See bottom rigth of page 40

I am talking to this seller from TFSA (which I never heard of before and they are new on Aliexpress) in case they could fix a custom version for me without shifter holes and raw carbon from the mould.
https://www.aliexpress.com/item/1005003099890350.html?pdp_ext_f=%7B%22sku_id%22:%2212000024086326303%22,%22ship_from%22:%22CN%22%7D&gps-id=pcStoreJustForYou&scm=1007.23125.137358.0&scm_id=1007.23125.137358.0&scm-url=1007.23125.137358.0&pvid=9d8c7f65-e52d-46a4-aa22-c9fb9fcfce03&spm=a2g0o.store_pc_home.smartJustForYou_6001726214177.0

As the seller did not have a headset to use a regular stem...
This starts me thinking if it is possible to use a genuine Tarmac SL7 headset and even maybe a genuine Fact 12R fork. There are no forks on the internet, but perhaps it could be ordered as a spare part through LBS.

Darimo seatpost? Understanding from the Velobuild 168 thread, Velobuild had a slightly different shape to their seatpost making it impossible to fit a Darimo or a genuine SL7 post. Is it the same for all "copy" frames?

IIRC TFSA is the OEM behind brands like Sava, Twitter and Delihea

Rather than being a simple purveyor of generic frames like most open mould brands, TFSA is a bit different because they got their start making literal fake frames. In terms of general credibility and quality, I'd rate TFSA below the average open mould brand. There is no guarantee that tolerance critical OEM parts (especially seatposts) will fit either because although they may appear close, dimensions will never be truly 1:1 since they're not working off the same factory mould.

Handlebar considerations – a hint

Along with the 168 frame I ordered a 100/400mm fully integrated handlebar. I also ordered the VB-HB-021 (2021 New Carbon Handlebar with Separate Stem) with a 110mm stem and a 400mm bar. With the VB-HB-021 option I intended to have a longer cockpit compared to the fully integrated one. However, it turned out that the VB-HB-021 option is shorter than the fully integrated one, although number wise the stem is longer.

Handlebars and stems are always very tricky. What you have seen could have been seen beforehand (if you know what to look for and know about the hurdles there.)

Lets assume the integrated one also has a bar and stem part to explain your problem.

The integrated bar has a given reach of 80mm vs the 75mm of the separated bar. So with identical stems the integrated one would be 5mm longer - this would lessen the difference to 5mm with identical 100mm or 110mm stems.

BUT the stem angles are different - the integrated one levels out, while the separated one still has some upward angle.
This is very hard to decipher from the website - I tried to illustrate this below.

1 is the separated one - see the angle? Also visible in the placement of the measure of 90/100 etc.
2 is the integrated one - no angle at the connection point.

So if you are just looking for the "reach" of the stem the 100mm integrated one is probably more like 95mm and the separate is angled so much upward that 110mm might be less than 100mm - combine this with 5mm less reach in the bar and your observation makes sense.

You can play around with the Stem Comparison tool to figure things like this out in more detail: http://yojimg.net/bike/web_tools/stem.php

BTW: Full disclosure - I would have made the identical mistake and as I went with the integrated bar and had to guess the real reach with no real angle given it came out a bit different than I planned... paired with the long SRAM Hoods my fit is a little off, so more spacers than planned have to stay for the moment.

Re: VB-R-168 & FSA SMR stem The FSA SMR (assuming you mean ACR/SMR) system uses a similar, but different top/headset cover and c-clip design than the supplied hardware from VeloBuild.

If you choose to use FSA's ACR system you will need the following:

1. ACR Top Cover / NO. 55R 1.5" ACR STD headset system.
2. An FSA ACR stem or ACR integrated 1-piece cockpit.
3. Any ACR spacers if the headset system does not include them.
4. Most likely a thinner upper headset for the headtube opening, because the ACR system in general leaves quite a bit of "gap" between the new top cover and the headtube. The supplied ACR c-clip is pretty thickkkk.

A few folks in here have been able been to use a hybrid mix of both Velobuild and ACR headset hardware. Just depends how deep down the rabbit hole you wanna go. The stuff listed about will at least get you where you need to be.
