(via ちろの山岳自転車哲学 ・リローデッド・ 2013 RockShox Revelation 650B: 2013年はね、650Bが来るのよ。)
知らなかった・・・
A veritable tsunami of 650b bikes and components is bearing down on the global mountain bike market. Even though the wheel size—halfway between a 26-inch wheel and 29er—is not new, the product category has been relegated to the fringes of the market. But the flood is coming.
Both Fox and RockShox are making all-new fork models with 650b-specific lowers for 2013, nearly every tire manufacturer surveyed for this story acknowledged they have new 650b product in the pipeline, and even though they won’t fess up to it this early in the game, some of the biggest bike brands in the industry are already on board. Expect to see some unexpected companies field their first 650b bikes in 2013, followed by some serious market saturation in 2014.
