Highlights: The Vertex 70's frame uses proprietary Rocky Mountain aluminum tubing (they call it Form). Calling the top tube and downtube shapes unique is an understatement. Even an untrained eye will notice the downtube's shape change to meet the different load requirements of the bottom bracket and headtube area. The internally-butted downtube twists and widens to almost 2.5 inches wide at the bottom bracket. All this manipulation negates the need for external gussets. The seatstays and chainstays look more traditional while offering great tire clearance (something Rocky Mountain riders expect).

Best quote: "The narrow bar made tempo climbs a real treat as the bike calmed down and held a predictable line. We got back in the saddle and used a more spinable gear for the best results on the climbs. We need to mention that the bike's weight distribution is a real delight. Riders didn't have to work to keep the front end down or slide around looking for traction."

Bottom line: How can you call an aluminum hardtail versatile? Simple. Want to race cross-country? This bike will do it. Want to be part of a 24-hour race team? Get your partners on this bike too. Never plan to race but want a responsive, lively bike that doesn't demand its rider be in Olympic shape? This bike doesn't punish the rider who has a job. Finally, don't want to lug around a lot of extra bike that may be overkill for the trails you ride? The Vertex 70 keeps things simple. If you look at the Rocky Mountain Vertex 70 as a poker hand, you've just been dealt four aces.
