Bike Attack loves Shimano components; Ericson's middle name is practically "XTR". We will always recommend Shimano Cranks, Pedals, Derailleurs, Wheels, and Brakes. Shimano is the leader of the global bicycle component market, commanding approximately 50% of the market share. Its products include drivetrain, brake, wheel and pedal components for road, mountain, and hybrid bikes.

These components are generally organized as groupsets intended to be used as a near complete collection of a bicycle's mechanical parts. Shimano does and excellent job of categorizing their components for specific uses, weights, and price points.

Newest addition to their line is the electronic shifting system DI2.

Bike Attack is a certified DI2 service center.
