Rocky Mountain Oxygen 50 AC Road Bike

The Rocky Mountain Oxygen 50 AC Road bike makes getting out and enjoying the pleasures of cycling a straightforward process. While miles roll by, reliable and intuitive components like Shimano 105 shifters and FSA Gossamer brakes do their duties effortlessly. By mating up a 12-27 cassette to a compact crankset, the Oxygen 50 AC offers a gear spread that can climb mountain passes and chip away at century rides. A century may seem like a daunting endeavor, but the formed aluminum front triangle puts all your effort into covering ground and carbon seatstays keep you at ease over road imperfections for mile after mile.

  • Triple Butted Aluminum main triangle with Delta Process Molding for tubing shapes that increase lateral stiffness
  • Carbon Seat stays and Fork work to correct annoying road imperfections
  • Easton EA30 bar and stem combo for positive steering input
  • Shimano RS-10 wheelset with bladed spokes for cutting through the wind
  • FSA Gossamer cranks with compact rings for high cadence spinning

Bottom Line: Get out and ride.

I'm thinking about buying an Oxygen AC 50. Although i've

I'm thinking about buying an Oxygen AC 50. Although i've never ridden one, it's got great components for the price and a trusted name. However, having never sized one out, I'm looking for some input. I'm 6'2" with about a 33 or 34 inseam. I've been looking at 58 cm bikes locally, but I'm thinking the 60 will probably be a better fit than the 57, especially since I'm looking for a more upright riding position and I wouldn't want to have to extend my seat post a ton in order to get full extension. Any suggestions? The bikes I've been testing at 58 cm are the Cannondale Synapse, Specialized Secteur and allez, if that helps at all.

Patrick I am 6-2 and I would get the 57. It has a 575mm top tube. A Specialized 58 has a 582 and a Trek 58 has a 573 ... this is right in the middle of these two popular bikes. So maybe you need to think abou tif you like to ride really long... You are in the middle of the two .... Too long is a big problem ... I would bet most guys 6-2 would be happier on the 57 tho...

Patrick,

You're right the 60cm will be a better fit for you. The 57cm will be too short.
