So, Tandem users,
The last few weeks I have been dealing with cracks in my Santana Sovereign frameset. I had always thought Santana was one up back in 1996 when I purchased the tandem. I have never had a frame failure on the many single and also tandem rigs I have owned over the years. Now I have to deal with Santana for cracks on the head tube and stokers seat tube on a 1996 frameset. Back then, we were a 300 lb. team, the captain being 180 lbs. The frame is anodized purple, from what I have read, anodizing will harden the surface. Is this hardening enough to cause a stress crack in the head tube and stokers seat tube (just above the seat stay weld to under the stoker seat clamp area). My main worry is that they will want to repair the frame and charge me the paint cost. This is a double edge sword, meaning I purchased this bike because of the anodizing since I sweat so badly, paint peels before my eyes. And yes, the anodizing also shows sweat stains. To me a new frame would be the best solution as I now don't trust the old frame because I feel that it may be brittle do to the anodizing. Anybody have any thoughts?
