Any have a similar experience?? I am riding 808 Firecrest CC rear wheel with a 23mm Tangente tire, on a Parlee TT frame. I have some slight wear on the sidewall(s) of the rear tire, and have realized that sometimes when I get out of the saddle to sprint or climb or accelerate, the side wall of the tire brushes the frame near the BB/chainstay junction. Is this slight wear dangerous?? Anyone have the same and switch to a 21mm tire and have it resolve? Thanks for input..

yeah that could be bad, theres not a lot of material on those sidewalls

horizontal dropouts? can you adjust it away from the chainstay it is hitting?

According to zipp's website they recommend a 21mm tire, which is wierd because on Hed's website they say if you run anything less than 22mm tires you void the warranty. Aren't they sharing the same patent or are the new zipp's not as wide as the Hed c2's

Did you have this issue in the past? Is it the tires or perhaps the frame?

I have no understanding how patents work but why if the Firecrest shape is so great did Zipp not patent it, seems like with other companies like bontrager, Flo and others starting to create similar wheels for much cheaper because they don't have the same level of R&D that Zipp is going to make their other non Zipp wheels obsolete.

Patents work badly in the US ;-)

That said not everything is patentable and lots and lots of things have been done in the past. It possible that the Zipp shape is predated, but just not marketed. Or given the cost of chasing down patent violater they may have decided its not orth the cost to patent the shape.

Actually, patent enforcement can be quite profitable. Most companies cannot afford to challenge a patent, so rather than go through a lengthy, expensive and uncertain challenge, they will simply acquiesce and pay a licensing fee.


Specialized does this all the time with "their" patent for the Horst Link.
