what's the travel on your fork?
I'm really really tempted to pick up a dbair. Just something about it makes me really want one. Also want a Santa cruz v10 which would never be used for its true purpose as my sc blur lt is more than enough bike for what I end up riding.
I ran a DBair on my Aurum last season, and have run DB coils on my DH bikes for over 5 years.
the DBair is godly - tons of adjustability and very little stiction (worlds better than a vivid). be warned that running one really depends on the suspension characteristics of the bike, as it does ramp up at the end of its travel. I upgraded mine to the larger air cartridge, which makes it more linear, and it works well on my Aurum. but not all bikes will work well with an air shock.
coop - few DH brakes on the market match or beat the Saints (m810s and m820s) for power or fade. I run Formula the Ones, and have zero fade (and monster stopping power), but few shops carry Formula parts. if you have any issues while riding, you're pretty much hooped unless you're in Whistler.
there's a good chance that I'll be switching to the new Saints for this season. they seem to match my Ones for stopping power, and every shop in Canada has parts for Saints.
right now I'm in a dilemma. started shopping for a more jump-friendly DH frame and had my mind set on a Banshee Darkside. went into Calgary Cycle last night, and they offered me a screaming deal on an Intense M9 frame.
was initially looking for something with ultra-short chainstays (~16.5"), with 7-7.5" of rear travel, but with the deal they offered now I don't know what to do haha.
decisions, decisions.
