Upgrade your downhill bike to a 7 speed DH specific drivetrain.
Get the major benefits of X01DH for a fraction of the cost. OneUp Components' DH Block converts a 9,10 or 11 speed mountain cassette to a 6 or 7 speed downhill cassette, with integrated spoke protector and 2 tooth jumps through the majority of the cassette. Get faster, more responsive shifting; no more multiple shifts to find the right gear.

SRAM: X01DH is great, but who want's to spend $300 on a cassette and have to upgrade to an XD driver? Buy a DH Block and a new SLX 11-36 mtn cassette and you have an 11-24T X01DH compatible 7 speed cassette for less than $100!
SHIMANO: Converting a 10 speed Shimano DH groupset to 7 speeds lets you take advantage of the great value Zee rear derailleur and shifter. Another plus, the Shimano Shadow+ Saint and Zee derailleur designs are much lower profile than X01DH and less vulnerable to trail strikes.
