RLucas Posted May 30, 2019 Share Hi Hubbers! I have an aluminium MTB rim which has started to split open at the point where the rim is joined. While the rim tape and tyre hold the rim together well enough, I can't convert to tubeless because of the air leak. Any suggestions for repair centres in CPT? Will it need to be welded? I figure soldering the joint won't hold well enough Please help! Louwtjie86 1 Link to comment Share on other sites More sharing options...
Chavo Posted May 30, 2019 Share Sounds to me like you would be better off buying a new rim. I would suspect that joint in the rim would always remain weak, even if it can be repaired Link to comment Share on other sites More sharing options...
droo Posted May 30, 2019 Share That's not a problem you're going to solve with a welder - rebuild with a proper tubeless rim and you're goo to go. Yusran, Sepia, RLucas and 1 other 4 Link to comment Share on other sites More sharing options...
mahleu Posted May 30, 2019 Share Is it a double walled rim? A good aluminium welder should be able to fix it, you may need some extra sealing of some sort to make it airtight. What size rim? There are usually a few loose hoops floating around the classifieds. RLucas 1 Link to comment Share on other sites More sharing options...
Yusran Posted May 30, 2019 Share What size rim do you need? I have an old pair of 29" white Crests just hanging around in the garage, never used but old and dusty.

RLucas Posted May 30, 2019 Share I really don't know... it probably is. it's the standard wheels on a Momsen AL651... rebranded Alex Rims. Thanks for the question... I didn't consider the double wall. I'm gonna consider the welding option before getting replacement rims Is it a double walled rim?

Yor dude! Thanks for the generosity! Unfortunately I have a 650b at the moment... first mtb so paying quite a bit of school fees What size rim do you need?

Louwtjie86 Posted July 24, 2019 Share Hi Hubbers, was searching for a forum covering what I found on my rear rim this afternoon, couldn’t find anything specific, thought someone here might have some answers. Found a small bubble on both sides under the rim decals where the rim is joined together. Definitely not seen it before, can it be some form of rust? Front rim still looks perfect.

Alouette3 Posted July 24, 2019 Share Very likely just the decal lifting. Water etc can creep in under the decal at the joint,. remove it and take a peak underneath if you are concerned. My 29er DT Swiss 1900 rear rim is also splitting at the joint and leaking air. Stans is sealing it, but I need to start looking for some replacement.

V12man Posted July 24, 2019 Share I'm gonna consider the welding option before getting replacement rims This is NOT an economical way to go - no longevity either - listen to droo and replace the rim gummibear 1 Link to comment Share on other sites More sharing options...
