They say 45mm tire clearance, not 54mm. Having designed mine with Waltly (see this thread: https://chinertown.com/index.php/topic,4490.0.html) I realized it is not that straightforward to make a really big clearance gravel frame. Several items get into the fight to limit it:

- internal routing
- short chainstays
- standard seat tube
- cranks with small Q-factor / large chainrings

all of these complicate having a very large clearance. So either you sacrifize the internal routing on the right chainstay, or you make the chainstays longer (>440mm), and/or you make the seat tube curved or joining the bottom bracket rather on the front side, or you put some cranks with larger Q-factor and maybe a wider bottom bracket.

In my case, my compromise was a standard 50mm clearance, with chainstays at 435mm, shift cable going below the right chainstay instead of inside (although going AXS in the end, so this does not bother me ).

My 10-51 from vgsport with XD hub works perfect with my GX AXS. That is the experience I have so far.

Nope but I find it quite useful. Thanks mate.

However, I still need to find a UDH gravel frameset. And I have no idea if there are any available. I see that in some you can choose the BB but never seen UDH finish.

I made a custom titanium one with an udh hanger to test in the future the new derailleurs from SRAM, but for now I was planning to use it with the old GX AXS non-T.

Frame reach of 390mm with a stack height of 582mm for a size 56 JH-10 is considerably upright for being advertised as an aero frame.

Don't look only at the reach. The top tube is really long because the seat tube angle is quite slack. Actually the geometry in that bike does not make much sense. I would have expected a much more vertical seat tube to move all the weight to the front and get a much more aero position and more efficient pedaling.

The JH-15 is really nice, except for that super low stack: 540 in size 54. That is just too damn aggressive for the average Fred (i.e. Me). My custom titanium has 60 mm taller stack than that

Ok, it turned out quite well actually and they accepted some discount for the mistake and change of plans. So yes, for now I can keep my recommendation on this manufacturer (Waltly)

First picture from before, the others from after the fix. You can see it, but  not very noticeable I think.

A friend and I are working with a manufacturer on two custom TI gravel frames. Due to miscommunication between their sales/manager and their engineers/designers, they made a mistake in the front derailleur mount. We specified clearly and many times that we did not want a welded mount, but something removable. The sales manager understood well that and confirmed that, but apparently in the final design that was left out and nobody noticed (I honestly looked at it, but thought it was indeed the corrrect design, apparently it wasn't). They are aware it was their mistake though.

In the end we are going 1x chainring, and we are left with this fixed in position. It is honestly a real pity, because otherwise the frame looks great amazing, the manufacturer did a great job with the welds and we  are  very happy how this turned out.

What can be done about it? The manufacturer says a screw-mount at this point is out of question, and so is re-making the frames, but that may be able to remove the mount and we can use a tube-clamped hanger if needed. I guess they would cut it out and polish?

- Do you think they can eventually get a decently looking tube doing this cutting it out and polishing the frame?
- How about structural integrity? any thoughts about this? would it be safe? or prone to failure/crack?
