Re: Black Roughtop
Team 177 does not use SBR rubber from McMaster. They found a local supplier who gave them various samples of rubber and tread material. They took those samples home, tested them at various loads on carpet, and selected the material that suited them best.
That's about all the info I have, unfortunately. So, I can't comment on the exact material, who the supplier was, or what their results were. Just another note, they are not using the IFI wheels this year. The wheels are custom made from pipe/tubing and welded end caps. Very slick.
