Diamondback Hook 27. 5" BikeHooked On RidingWhen it comes to fun out on the trails, nothing quite beats a long-travel hardtail. Hardtails are great for climbing, singletrack, descending, and just all-around fun. The Diamondback Hook 27. 5" Bike is easy to pedal up the hill and is a bomber on the way down. It has an aluminum frame that uses 120mm of travel on the front. The frame is internal dropper ready, comes with an ISCG-05 chain guide with a roller, and has a progressive geometry. The Hook 27. 5" Bike comes with a SRAM X4 8-speed drivetrain. The drivetrain is great for moderate hills and longer rides out on the trails. Radius BH-960 hydraulic disc brakes provide reliable stopping power so you can descend under control. With the Diamondback DP25 Double-Wall rims paired with Vee Rubber Crown Gem tires, you'll be able to ride in a wide variety of conditions.
