Pra tirar algumas duvidas, eis aqui um texto que foi publicado no site da marca Dr. Neubauer (http://www.drneubauer.com/index.php?p=11&lang=us), especialista nos pinos de baixa friccao (baixa, jah que atrito zero so no vacuo):
Ban of frictionless long pimpled rubbers
The ITTF has indeed banned all frictionless long pimpled rubbers as from 01 July 2008.
This includes all our current seven long pimpled rubbers as well – as - all frictionless long pimples from other manufacturers.
The “Minimum Friction Level” of 25 micro Newton established by ITTF is so high that only pimpled-out rubbers with total friction will be homologated after 01 July 2008 (the friction level concerns both the surface and the side of the pimples).
There are no changes regarding the current season (2007/2008). Thus you can use your frictionless long pimples until 30 June 2008 without any problem.
We have already started working on new long pimpled rubbers one year ago. These will have friction yet have a promising disruptive effect.
These new rubbers will be ready by May/June 2008 approximately.
Therefore we recommend that you keep your current equipment until May 2008 and then switch to the new rubbers.
