That's not bad. If you like the bike, do the repair and get a many more miles out of it. It should be just as good as new.

I would also have them look it over for any tell-tale signs of impending doom elsewhere on the frame.

I owned a Speed TR (my first folder), that and the TT are from the same time period. Looks like the same frame to me.

Thanks. Interesting, the crack is across the weld. Other instances that I've seen, the weld is intact with the fracture just beyond the weld suggesting that the welding weakened the neighboring material.

FYI, the FnHon frames tend to be of slightly higher quality in terms of the paint and weld finish. As far as I can tell, Litepro no longer sells frames for rim brakes. Disc only with Litepro.

AliExpress for an Fnhon frame looks a doable option, delivery is not actually extortionate, LitePro store's prices are extremely competitve, albeit only the disk brake option shows up when I search, hopefully if I message them they can reply pointing to rim brake option. I like the purple one! Very plummy!

If assembly is way beyond me I will more likely get a mechanic to assemble.

Would anyone know, is the frame for the Speed D7 or Speed TR measurably/geometrically any different to the Speed Pro TT frame? I can see some second hands going around, squinting at online photos they look the same thereabouts? My Pro TT seems to be much rarer whereas I can probably source a D7 fine.

So seems there's options, this thing will live on one way or another

Thanks!
Welding a frame is doable but, your have very little material to work with; the fracture is very close to the hinge pivot point. And, without a jig, it is very complex.
As other said, the Fnhon is a great option but if you need it quickly, it wont work (I had to wait 8 weeks for my litpro wheel to arrive near Malmesbury.

Did you call CH White? They may still have frame which they do not advertise on the site. My smooth hound and Hammerhead were in a corner of their stock room

Alternatively, you could by a cheap second hand Dahon or Tern link from ebay/facebook etc.and transfer all the parts of the broken Speed TT to the newly purchased bike. At beginning of lockdown, I converted my HeliosD7 (budget thing) into a "helios X18TT" fitting parts that comes with Dahon speed TT or Tern Verge X18.
There are 2nd end speed D7, vitesse d8, tern link c7 for sale ~140/160 at the moment

oh that suuuuuucks....

It's time for a New frame.

You don't want a weld that close to the hinge. It's just not worth it.

Is folding a requirement for the frame replacement?

It looks like the break initiated with the hinge and caused the weld in the upper portion to fail. Just guessing.

If you look for an old 406 20 inch wheel Phillips badged Dahon their frame is a 4130 chromolly frame and much the same as the old Speed Pro bikes..In fact any old chromoly frame made by Dahon should do the job pretty well as long as they have the conventional derailleur..
I bought a Dahon Vybe recently for 10 just for the spares..It was in a very poor state but I am very impressed by the frame..looks well made and very good for an alloy frame..
