Sadly, I just had to glue up my last two pristine Veloflex Crits. I thought I was going to be able to patch the Vitt CXes, but the tubes came out looking like wrinkled prunes. Only one had sealant in, but both were thin and stuck together. Funny thing is that I have some of that same tubing in my patch kit which feels just fine, but it looks as if wear has chafed a lot of the tube in these recent flats away. Anyone have this experience? On a similar note, can anyone compare the tubes Veloflex used in the early 2000s in their Crits with those they use in their current sew-ups? The old Veloflex tires seems to have beefier latex tubes than the Thai made Vitts I first used on my Mooneys.
