I know Phil Wood makes an adjustable BB called the Taperlock but I was curious about this Race Face one called the Taperlock as its cheaper and doesn't require any special tools. Has anyone had any experience with it? How much adjustment does it give?

Quote from Speedgoat website:
"We love adjustable chainline bottom-brackets. In fact, we tend to think they're necessary when truly dialing in a bike--making sure it not only shifts well, but also lets you backpedal through technical terrain, and maximize your chain's life. Though the taper is too abrupt to work with Campy and some other cranksets, this is on our short list for favorite bottom-brackets."

The 'taper is too abrupt to work with Campy some other cranksets' part worries me somewhat but I generally use shimano and I imagine that would be ok.
