Rocky Mountain Bicycles unveiled a new model today--the Thunderbolt--a bike that blurs the lines between cross-country efficiency and trail bike confidence. Or, to quote the press release, "When XC gets rowdy, the incredibly agile Thunderbolt shines.... At last, an XC bike dedicated as much to flowy singletrack as to punchy technical climbs."
