thanks guys. i live in chicago and the winters out here suck big time. have to skate indoors, and the indoor masonite pool i skate is so damn slick you slide alot and need something grippy. im waiting for the vallely lightning bolt to come out and il set that up with a set. should be a good combo. ;)
I don't know an actual number but I'm guessing around 88a or so.It's been too cold here to go out and test them and our indoor park is closed for good.Should be warm enough this weekend to give 'em a rip !!!!
STF's and SPF's are over 100 on the A scale which does not actually go that high so if you extend it out they are between 103-105a. Bones started using the b scale which is more accurate for the hardness of fast skate wheels but this confused people who were only used to the A scale so Bones decided to coin the SPF,STF,DTF and ATF terms for their lines.
