Re: Frame sliders?
LOL..., mine have had crash testing, you could say that.
I stand by Vortex..., get the base, only have to replace the delrin pucks, it's nice.
I wore one down at Barber and still have a bunch of "rash" room on it. Then I had a nasty get-off at Roebling Road recently, and the engine mount bolt actually bent and the slider base was fine - a testament to the durability.
Speaking of delrin..., if you need some knee pucks, I'll swear by oesaccessories.com now. If you do STT days in the SE, it's the twin's shop that do the tire mounting..., anyway, these pucks last!!
