Bike Description

27.5"-Wheels; the perfect combination of fast-rolling and maneuverability. The Nail Trail 27.5 features a 100mm Rock Shox Reba fork with a 15mm Maxle through axle, a Shimano Deore/Deore XT 2x10 speed drivetrain and new M615 Deore brakes, and Schwalbe Racing Ralf folding bead tires.

Bike Features

Hydro II Tubing

Hydro II Tubing

Hydroformed 6061 aluminum-alloy frame tubing engineered to tune the flex properties of a frame with high precision, providing stiffness or flex exactly where desired and maximizing frame performance. Hydro II is our second generation engineered shape tubeset which provides lighter weight tubing with similar strength and ride qualities as the previous generation.

27.5” Platform

27.5” Platform

Newer frame layouts designed to maximize the inherent benefits of 27.5-inch wheels, which combine the speed and stability of 29-inch wheels with the agility and acceleration of classic 26-inch mountain-bike wheels. 27.5" wheels allow a clearly different riding feel than 26" or 29" frames and bikes. This platform blends the features into an true all around Mountain Bike that satisfies the needs of many different riders. It has some of the rolling efficiency of 29ers, but coupled with the more robust and stiff feel of 26" wheels.

Tapered Head Tube

Tapered Head Tube

As bicycle forks evolved, the diameter of the "steerer tube" of a fork, and the "head tube" of the frame (which houses the steerer tube and headset) have steadily increased. Years ago, forks were fairly standard at a 1" steerer diameter. This increase to 1-1/8" (also known as OS) in the 90's, and even 1-1/4" and 1.5" sizes became some what common. In particular, 1.5" was used on Freeride or downhill frames due to the inherent increase in strength that comes from the larger diameter. But there were some problems, 1.5" forks required very large head tubes, and were heavy. As the sizes evolved, it was realized that using a tapered steerer tube would offer up the best of both worlds. Marin uses tapered forks that have a 1.5" lower diameter, but then taper to a 1-1/8" upper diameter. This reduces weight, but keeps very high strength where it's needed, at the base of the steerer tube, where it meets the fork crown. This type of tapered fork greatly increases stiffness and strength, while keeping weight to an absolute minimum. Unlike maky other companies, if a Marin bike has a tapered head tube, it also has a tapered fork, to take maximum advantage of the technology.

Marin Race Geometry

Marin Race Geometry

Frame layouts optimized for competition and hard efforts, placing the rider in the most efficient position for pedaling and steering inputs. Longer effective top tube and shorter chainstay lengths put you in a more stretched out pedaling position, and keep the rear wheel closer to your center of gravity for sharper handling.
