Its just generic Peter, they all came in poly sleeves, stapled both ends, no markings or anything, they are very similar to the fusion ones, but fusion they aren't!!
From memory, they are knurled in the guts bit, and once nipped up, I've not had one slip.
I wish I could find more, but haven't as yet, of the 4 i've had, 3 have been on stolen bikes, so they are out there!!! (let me know if you find one on either a 94 shredder, 04 quad or 07 retro ripper!!)
