Glue Metal Saddle Post Clamp

    Anyone recommend a metal glue that might work on this ? i tried Gorilla Epoxy but no joy.

    The clamp is specific to Rose bikes and I am looking for a replacement from them but there is an unspecified delay on the order. I've asked what the story is and if the part is in stock (even though it was listed as in stock) and am waiting to hear back.

    Is there such a thing as a metal glue which would do that? I'd assume it's a lost cause, with such small glue areas.

    As magicbastarder as pointed out, there's insufficient contact area on that. If you're determined to give it a go, perhaps an external curved strip could be bonded across the break and around the front of the clamp. That would give you more surface area. Personally, I wouldn't risk it.

    The problem with gluing this piece is that when you use it, the glued joint will be in tension, in other words using it, by default, will result in trying to pull the glued joint apart.

    The other problem is that you're trying to glue aluminium (I presume) in, as mb pointed out, a very small contact area.

    What might work is an epoxy putty (Quiksteel is a brand name). As the name suggests it's a putty rather than a liquid, so you might be able to build up a layer outside and around the break, which would be stronger than just gluing the face.

    You could combine that with mefistofelino's idea of a piece of strapping, and build up the putty at the edges of the join as well as the face.

    A real bodge job might be to use a jubilee clip around the seat post clamp when you have it back in place, but again, I don't really know if I'd trust any of the above

    Thanks guys.

    Regarding risk there was a bang when it happened and I initially had no idea what it was. It was only a couple of minutes later then the saddle started dropping that it became clear. Fortunately I was only 1 km from home so the out of saddle riding wasn't too much of an inconvenience.

    The part is

    Anyone recognise that as a rebranded somewhat standard clamp that could perhaps be found on other bikes models too ?

    I don't recognise it, @harringtonp, but I'm interested in the failure mode of that part. Given where it snapped, I'd be interested to know if you used a torque wrench when tightening it up

    That's good to know thanks. They hadn't come up in the initial searching I did

  • Registered Users Posts: 2,568 ✭✭✭harringtonp

    I can't remember. It was last tightened at least months and probably years ago. I do have a torque wrench and even if I tightened it without it, I'm usually careful not to over tighten.

    The clamp is 10 years old, came with the bike in 2013

    Just be aware - that exact same ad came up for me in several different websites in different countries. Maybe some webscraping going on?

    It's on stock on Rose when I go onto it, maybe check again, or does the delay only show when you are at checkout?

    I had ordered it well before posting this but the order was in a processing status for a long time.

    Got on to them, think they had difficulty finding the part but it is now on its way to me.

  • Registered Users Posts: 2,568 ✭✭✭harringtonp

    Does show the risks of purchasing bikes that use non standard parts.

    Rose aren't too bad. The saddle post, clamp and saddle were quite specific to them but the rest of the bike pretty standard

    I believe Canyon have been non standard in the headset area

    Aye forget about trying to glue that you'll just be wasting your time. It wouldn't even torque up let alone be durable.
