I have about 2500 miles on my custom Waltly 29er frame.   On my most recent adventure, I noticed that a crack has developed in one of the top rear triangle tube where it is welded to the seat post tube.   I just wrote Sumi at Waltly, and asked what to do about this. 

Wow that looks quite dangerous! I'm curious to see what will happen.

I don't think it is dangerous leading to a catastrophic failure.  It appears to be a stress crack right at the edge of the weld in the heat effected zone of the seat post tube.   These types of cracks next to a weld are often due to improper purging of the area during welding where oxygen reacts with the metal causing it to become brittle.  Sometimes this type of crack can be due to too much hydrogen in the area as well.

If you are up for posting some photos of this build, I'd be grateful. I'm considering Waltly for a gravel build and I'm currently looking at one of their standard frames. Not sure if it's the same one you have.

Sorry, hadn't seen this post Photos

My Waltly going 3 years strong, I've used it for road & Gravel, no dramas..... I'll be ordering a second in a week or two

* Dates are when bikes are built not when frame were received.

Nice builds !

I'm going to buy a titanium from from titanproduct. They've been responsive and helpful with the alterations to a frame I'd like. I'm waiting to hear back on final details but I'll make a post in the future when I have ordered it and then ongoing after receiving it and building it up.

And then an update if i ever remember, likley not if the frame is going strong but definitely if it cracks!

Does anyone know how much a Hi-light G0 3d printed bike costs? Just want to get an understanding of the prices of 3d titanium nowadays

You would be lucky if they even talk to you without being an OEM. Hi-light was yet only in b2b.

Have you tried asking [email protected]? They once commented on an IG post, but not sure they truly considered B2C or if they stayed with B2B, only.

I did ask them, and they didn't give me a price, but they did give me the name of their local distributor. I also found out that their G0 gravel isn't out til May - so we don't know its pricing yet either.

i tried to find someone in AU but no luck, only option for me so far is a online store in singapore called carousel.... frame selling for about $3000

Looks like one can get it in China for the equivalent of about 2200 USD. Uploading a PDF print of their Chinese "eBay" store.

Thanks for this. Here's the TL;DR on the Hi-Light G0 based on your pdf:

1. 45mm max tire clearance
2. ~$2190 USD
3. Looks really nice based on the photos

My take: the Waltlys are better priced at around $1600 for also a 3d printed bike, and based on this forum at least, has more of a track record.
