I have enduro fork seals on my sid, and holy crap they are amazing. I took the SID apart to check for dirt inside (just to test and see if these seals are that good) and they are. I know some people who complain about the fork wiper seals on rock shox, but think of this also. Enduro fork seals, not only being superior to any and all wiper seals out there, are actually 5 dollars less including shipping than OEM seals! ANd i think this thing with rock shox stuff breaking down is a lot more BS then truth
