2019 Iron Horse Bicycles Aluminum Frame Unity 3.1

Lightweight and agile, the Unity is ready to hit the trail. The entire Unity lineup has hydro-formed aluminum frames that are mapped to eliminate excess material where it isn’t needed and increase material in areas of the frame that experience higher stress. This keeps the Unity lightweight but also strong in places where it needs to be. The Iron Horse Unity 3.1 model features a great component lineup including the XC aluminum hardtail frame with SR Suntour XCT suspension fork featuring hydraulic lockout that provides a lightweight yet durable ride. The Shimano Alivio/Altus 27-speed drivetrain with Shimano Altus shifters offer quick, smooth gear changes that will have you cruising at speed downhill and pedalling easy while climbing. The Promax hydraulic disc brakes ensure precise stops in all conditions. Hydraulic disc brakes are the top of the line in the mountain bike world and use hydraulic fluid inside of the cables instead of a wire to provide the most stopping power with the least amount of effort. Take off on your next trail adventure with the Unity 3.1 by Iron Horse.
