Cracked Titanium Frame

Was shocked to discover this crack in my 10 year old Lynskey frame. Is this worth trying to repair? I use the bike mainly for urban and some gravel riding. Does anybody know of someone in Cape Town who might do this?

Chat to the guys at Calculus bikes... they are about the only people I know of that do anything remotely Titanium.

 

That or some aero engineers out at the airport?

Hi, Ti welding is mostly done with TIG, and although a lot of guys can do beautiful TIG, the so-called thin wall welding of titanium makes it a different beast.

 

I would be cautious doing a repair on the position of the crack as its one of the areas on the frame where there's is the highest stress/strain and a welded repair could make future failure unpredictable.

 

Your welcome to drop a pm to discuss further.

 

Thanks,

Thanks for that, I had my doubts because of the position of the crack. I always used to joke about my "Nukeproof" bike.

Just make sure you check the fork length of your fork vs what is prescribed in the warranty.

 

Check the terms and conditions vs your bake setup and make sure your answers and pictures all fall within the allotted bench marks.

 

If you were running a 120mm fork on a 100mm frame OR even a longer 100mm fork than recommended they may start getting sticky.

 

Good luck!
