Marin Bikes has been around since 1986 building many great bikes. Based in the birthplace of mountain biking, Marin's road and cross bikes should not be over looked. They are using a tube-to-tube construction on their high end road line that includes the cyclocross Cortina line and their long running Stelvio models as well.

Marin Cortina CX Pro

Highlighted here is the Marin Cortina CX Pro cyclocross bike with disc brakes. The all new for 2014 tube-to-tube construction creates a bike that is light, efficient and agile. The Cortina is available in frame sizes from 49mm to 60mm and the frame weight is approximately 1000 grams. The CX Pro comes with a full carbon fork with tapered carbon steerer and features Shimano's new Ultegra Di2 22 speed groupset with cross gearing and Shimano 785 disc brakes. The frame also features nice internal cable routing and a kinked chainstay for a bit of compliance as well as clearance for the brake caliper.

The Cortina CX Pro will be available this fall and will retail for $5499. The less expensive Cortina CX is available now and features the same frame but different fork, wheels and groupset for $2699.

Marin Stelvio

The Stelvio is Marin's high end road racer and comes with the same tube-to-tube T3 carbon construction as the Cortina, in a race-oriented package. The tube-to-tube construction means each tube is formed and mitered and bonded on a frame jig similar to a hand made steel frame for tuned ride quality. Shown here is the top of the line Stelvio T3 Pro DuraAce Di2. The frame has internal cable routing for either electronic or mechanical drivetrains and weighs in at about 900 grams.

The Stelvio comes in 6 models starting at about $2000 for a Shimano 105 level bike all the way up to the flagship T3 Pro shown here with Shimano Di2 electronic shifting which comes in around $8700. The $2000 level bike gets the same frame as the top of the line model so an aspiring racer in a budget can upgrade over time. The Stelvio is available in frame sizes from 49cm to 60cm.

Our Take

RoadBikeReview is looking forward to testing these two models in the near future. Marin as a whole, is a company that has refocused itself in recent months and has come out of the gate strong for 2014. The Stelvio has long been one of the best riding frames and offers a good value for the money.

From the Manufacturer

"The Cortina is designed and built for competition, but can be used for a wide variety of riding, including as a gravel racer, or versatile commuter. Cortina's have T3 carbon-fiber frames, disc brakes, wide-range double-chainring drivetrains, and larger 33-35mm tires, with tapered head tubes, Power Taper seat tubes, mechanical/electronic-convertible internal cable routing, and carbon straight-blade forks. Design features include Marin's responsive R2 Cyclocross geometry-stable through the corners but with an agile front end to hold the line-and wider frameset dimensions to fit larger tires."

"The Stelvio line is designed and built for racers and serious enthusiasts looking for a Tour-ready ride, with your choice of six component groups. These models offer T3 carbon-fiber construction, tapered head tubes, Power Taper seat tubes, RVS seatstays, PressFit 30 bottom-bracket shells, mechanical/electronic-convertible internal cable routing, and either full- or partial-carbon straight-blade forks. Design features include Marin's ingenious R2 Road geometry, precise steering, and high resistance to deflection from road-surface irregularities."
