Where to get replacement clamp for folding handlebars?

Hi everyone

I've been using this handlebars for some months now

They are not the best design in the world, as they sometimes come loose, and one time they were loose enough one of the quick release clamps broke as I put pressure on the handlebars.

Trans-x don't make them anymore, nor spare parts but I would like to repair them.

Problem is, it's a push button mechanism for release. I can't find any quick release clamps with push buttons.

So, has anyone seen any anywhere?

Thanks

I would be writing, calling or e-mailing the company that sold them or the manufacturer. You are not going to find parts from other sources. Google should find you where Tranz X is. They may even send you the parts or a new handle bar because they don't want the liability of that part breaking and you getting hurt. Roger

trans x , i expect just ordered a batch production run from someone over there.
they sold slow, so never re ordered.. you should have bought 6 .

if its worth real money a US Machine shop may be willing to try .. Doubt you will like the price.



How about a Bike Friday 3 piece handlebar?

mail me a camera.. or ask at Bike Friday . com in Eugene, Oregon.

heres the deal;
3 layers of Alloy tube.. 1 sleeve inside , bar halves of 7/8", and slit sleeve outside
squeezes the whole thing together, when stem tightened around bars..

a small bolt thru the face plate puts the split, consistently, in the center...
works same if stem face doesnt open, 1 bolt bar clamp around 1" tube..

Could you just replace the button lock cam lever with a non locking lever from a qr seat post clamp and then seek alternative means of keeping it from opening, starting with keeping it tight?

I did replace the broken one with a normal one, but they don't tend to have as much a curve on them than the supplied one, meaning they don't curve around the handlebars and don't lock up as much. Keeps coming loose.

I'm trying a couple of things at the moment. Will report back when I get some results

Sounds interesting. Don't follow exactly what you're saying, well sort of. Have you got a photo or diagram of what you're suggesting? Sent an e-mail to Bike Friday, so I'll se what they say

These folding handle bars are very interesting.. I gather you have added them to a bike as opposed to having purchased a new bike with them on.. It appears that they would make a bike narrower.. pictures?

Another alternative that I have seen recently for making a bike narrower is a stem that unlocks and turns the bars 90 degrees. It seemed simple and safe.

I was not successful in finding a goggle link

I installed the Swiss Nlock stem on a customer's Moulton ... very nice piece ..

I think fietsbob was referring to something like in the attached link
http://store.bikefriday.com/product_...ducts_id=13127

Traditional handlebars cut into and then a sleeve inserted.

Except NOT.. they have not shown everything they Make, in the online store section.

http://www.bikefriday.com/bicycles/mountain these are fitted with a split bar,
that they manufacture themselves.

For further information, use the telephone ..
