After distilling much of the information available on the "folding bike forums" over the years I always wondered how it was a Ti-Frame was NOT commercially available as a folding bike. I am curious about your project and where ever you have one built, it will be pricey. I would imagine it could get cheaper to have 5 or 10 built since there are questions of frame jig-set up and bulk-pricing, though I would be a bit skeptical about a Chinese-made quality Ti frame. It would be hard to do 'quality control' from overseas and determine the exact type of titanium tubing which would be used, welds etc. Also as much as I like the Swift design: I would also consider a "Folding Twenty" style ti-frame, preferable made in the USA. ( BTW: The guy slamming Bike Friday's should take a step back and look at who is actually building the brand of frame he has chosen to ride: What is their wage and how good is the quality of frame built by under paid/ under duress worker? Will they replace his frame when it breaks? )
Anyway, it looks like the project/subject you have raised might be a mute point since the good people at Swift stand by their product. I encourage you to weigh your old frame and compare it to the new one. I would love to know the weight difference of the new Swift and the old Swift. I think you will be surprised.
Always appreciate your information and experience on this forum.
The place I contacted is titanproducts.com. Sight only. I have bought a Ti Brompton seatpost from them before.
Good call on comparing the old and new frame weight. I expect very little difference, Al is so light, perhaps a few 100g.
Let us know if you go ahead with the ti-Swift I might be interested.
google of " titanproducts.com" . does not come up Titanium, referring to the metal..
but a Titan company with products
got the actual Link a non rusting seat post for the Brommy interests Me..
aluminum over a Carbon fiber tube epoxy bonded , is also an interesting Option
if it accepts 14 st in the saddle..
Their aliexpress store is
The Brompton post is
I am very satisfied with mine.
How long did it take for your post to come in? I've been tossing around the idea of getting one of the Ti ones off eBay,but these are much cheaper.
My mistake, it is titanproduct.com without the s.
Too bad its a zero set back head, the pentaclip off the back, and the saddle shoved back work .
no setback wont..
guess I can pester them about a 22.2 top aluminum post, telescope - sleeve arrangement..
jur - did you make the clamp on this seatpost? A neat idea -- with the bits well visible. Is it holding the saddle well? No rotation? (re: first photo, half circle clamp)
That's a standard current saddle clamp design. I haven't had it move. There is room for improvement on that design - the hole through the post for the rod holding the bolts should be as close to parallel as possible to the seat rails.
The company still has not gotten back to me regarding the frame quote. Not sure if they are back from New Year or not.
I received the replacement frame in the mail yesterday. Now to find some time to move all the parts over.
The new frame is 2.6kg, just the 2 main parts. More than I thought. I will measure the old frame once I have stripped it.
I have got the new Swift all built up and weighed the old frame. Came to a total of 2.0kg, so there is 0.6kg difference between the two. More than I thought. My scales are not that accurate though, it goes in 0.2kg increments.
Back to the titanium Swift:
I got a quote from the company to produce a Swift frame in titanium, to US$1200. A matching fork in titanium would be $200. Postage is on top of that.
It seems an acceptable amount to me. I do not have permission from Peter Reich to go beyond one frame, so if there are any takers to investigate a group buy, I will go through Peter to see how we will work this out. I am not interested in making any money out of this, I have a good job, so cost price only. Any profits from a group buy would go to Peter.
What kind of brakes? And are you still going with an extended tt?
I'm going to see Peter Reich in a couple of weeks, so I will mention the Titanium frame idea to him. I might be interested too if it makes sense ...
Jur, That actually sounds like a pretty good deal. Looking forward to seeing the finished product.
