Has any one tried both .Is the sp that much better its the same travel 8.2 but adjustable shocks too. Is the 570sp worth the extra $ .I may get a 15 570eps .I like the price 6500.I don’t ride hard or fast . I do need eps for all the rocky rough trails.the 570 sp does have a cool look to it nice rims its no faster than a std 570.is the old xp550eps better as far as shocks and ride and performance than all 570s? few new xp550eps left around .
