Craig @ Avalanche absolutely rocks! when he first came out with his fork cartridges I was the very first person to put one in a 888. his adapters were dialed in for Boxxers, but 888 adapters were still in the prototype phase when I bought mine. the ones he sent didn't fit right for my 888, and within 3 minutes of sending him an email he responded with his personal cell # to get everything properly measured and sorted out. new adapters were built in less than a day, and he didn't charge me to ship new adapters via same day courier.
Avy goodies are works of art. CNC'd (and anodized) aluminum used everywhere, the valving is absolutely spot on, and Craig bends over backwords to make sure you're happy. given the choice between Avalanche and PUSH, my money would go to Craig every time.
now that he's able to work his magic on shocks that are garbage from factory (specifically the DHX Air, yes I've owned one), that's something I'd strongly consider instead of PUSH or Cane Creek. I've ran CCDB air rear shocks on my DH bikes for the last 2 seasons (with multiple DB coils on the 3 DH bikes before that). and as awesome as they perform, Cane Creek's customer service couldn't be more brutal. had I kept my DHX Air, it would be sent to Craig and my DB airs likely would go away.
