An obscure wheel size is no longer a safe way to differentiate your rig from that rust bucket on the bike route next to you. Now even your uber niche 29 plus can be bought at Walmart for $199. First they conquered the $99 fixie, then came the 32'ers and now fat tire 29"ers. 650B is sure to fall next. Quick, liquidate your bike collection and switch to 27 1-1/4" before its too late!
