Am not sure about trigger shifters from SRAM, but I do know that Shimano is doing everything they can to push everyone else out of the marketplace, including limiting the ability of e-tailers to sell their products on-line, especially if there is a discount. Same as with Chris King products. Tried and true Japanese marketing 101. Sell with as little margin as needed to survive until you dominate the market and then take over and price and sell as you wish.
