Anyone got some experience with them?
Found a frame on https://www.aliexpress.com/item/1005006285866992.html (https://www.aliexpress.com/item/1005006285866992.html), which offers UDH. Probably you also could ask them to weld it into their frame with 54mm tire clearance.

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 :P).

currently on talk with the same seller regarding a frame... about to pull the trigger after correcting everything

Ok, I wasn't precise enough.
You are right, the posted frame has 45 mm. They offer a frame with 54 mm: https://www.aliexpress.com/item/1005005479664240.html (https://www.aliexpress.com/item/1005005479664240.html).
Thanks for your explanation. For me UDH is probably also coming into gravel (sooner or later). And I want to cut down my spares.
I don't care about external routing on the chain stays. I'd like to have internal on the down tube, sufficient for me.

Which one are you in? What do you want to change?
-
Was looking at this too.
These sellers have really confusing listings, showing completely different frames in different shots, no geometry listed, no shots of completed bikes. You will see the same picture in different sellers offerings, seems like all of these sellers aren't actually the manufacturer.
The welding honestly isn't that great as you can see a lot of undercut on things like dropouts, cable bosses, bottle bosses, etc...but at these prices it's not really a complaint that applies.

Adding customs logo and anodized headtube

Some of those welds don't look great. Store is less than a year old.
From the little I know, Ti is not an easy material to work with. Not sure if I'd risk that much money on an unknown vendor for unknown frames.

Any suggestion but walty? And also some cracked frames within this forum.
-
PYTitans and Waltly seem to be the highest regarded for titanium and even they have failures.

Do you know what are their reaction when a failure happens, do they stand behind their product ?

Not personally. The few posts mentioning warranty claims are not stellar.
-
Bought a frame... will tell you results once received :)
-
About Waltly, I read once someone cracked it and they offered a new frame at half the price or repairing it for free (but one has to cover shipping, which is not precisely cheap). I guess it is understandable for a rather small manufacturer.
Mine is already in Germany. Hopefully by the end of January I will start building it.

Which frame are you going for? Or you doing a custom build?
I checked out their store which I found a nice looking gravel frame with a squarish top tube

went stock on this frame + customs logos,
currently in productions, all the plans were according to listing and checked twice with them before giving my confirmation

nice! post some photos of the frame if you can. when you receive.
-
Now wait n see when it arrives...
-
Nice frame !
Looks super similar to my waltly. I wonder if they are all made in the same factory... ;D ;D
-
how did it all go?

how did it all go?
i have brake left to bleed, otherwise nothing to say.
welds are nice, frame is to geometry i asked for.
cant wait to try it out
picture is before ive passed all hydraulic lines
-
that looks really nice! what headset/bearing did you use? i'm currently getting my Ti built and mechanic is struggling to find a headset

The stock that was sent by the seller is this one

Bearing size are 40x52x8

annnnnnnd done!
Cant wait to good weather to try it out
-
Your post convinced me to get one myself! Have you gotten a chance to ride your new build?

rode it dozen times, getting a 2nd wheelset for more road (50mm with 32mm tires) and selling my rim brake, def my favorite bike

One legitime question, not trying to criticize. Why did you ask for internal routing frame if you where planning to use a standard / redshift stem?
I also have an internal routed titanium frame and I actually regret having made it internal, but I am not sure if routing it out at the bearing cups is the way to go, as more crap is likely entering the bearing areas through the cable openings, and you still get the harder maintenance of the bearings because of the cables goung through them

Why do you regret an internal routed frame? Did you go for an internal routing stem/integrated handlebar? I don't have the bearings on hand but if they're sealed bearings I can't see it being too big of a problem, might wear the bearings slightly faster but I can't see it being significant.

i liked the top routing rather than the frame side, cleaner look.
As for the stem, i had one in stock already, i might try full integrated or semi one day but i dont trust carbon handlebars

I ordered a frame and had issues with the derailleur and rear thruaxle threads on the frame, I showed the seller and they are sending me a replacement frame very quickly too. If anyone was wondering how their service was.

atleast thats good service
mine still flawless

Ordered mine about a month ago with some pretty extreme geo, but not as extreme as Evil Chamois Hagar.
Should be ready to ship next week, but I have yet to receive any photos.
@Ostriker how hard was it to get the special graphics on there?

not that hard, just make sure to be precise and easy to read since they use translators most of the time and review every single graphics and places

Have you seen vids of how fast they're going? their amps are maxed out and they're flying through filler rods! Absolute madlads, not surprising you see a few undercuts here and there. nothing but respect
