Steep and cheap has some great prices on Rockshox forks right now. And don't forget to factor in the $40 coupon code and the 9% cash back that ActiveJunky is offering. A 27.5 Pike RCT3 for $375 shipped with the coupon code then you get $37 back from AJ. Or the SID XX 29er 100mm fork for $396 shipped with $39 cashback. Or for $10 more you can get the SID RL in the Boost 29/27.5+ version.
