Where to get replacement clamp for folding handlebars?
 
2 Attachment(s)
Hi everyone

I've been using this handlebars for some months now http://bikeforums.net/attachment.php...hmentid=352732

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?http://bikeforums.net/attachment.php...hmentid=352733

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

Yeah I saw those, but they are not quick release. Unfortunately the other model they do, the FHS 2 are not designed to fold forwards.

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?

I looked for this on google but can't find it. Have you got a link to an image please

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.

fietsbob 12-09-13 11:25 AM

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 ..
