The Forge Edgmont is in keeping with Forge’s commitment to exceptional performance and price. The geometry on the 6061 all-aluminum frame is designed for control and responsiveness. Powered by the higher grade Shimano Acera drivetrain and Shimano Altus rapidfire shifters that perform effortlessly through 24 speeds. The 26x2.10" ITS Ninja Tires are designed for off-road riding yet equally suited for a ride through town. XCT-V2 SR Fork smoothes out nature’s terrain while the Tektro brakes provide stopping power and reliability. 17.5" frame stands over 30.8H" fits most riders 5’5" to 5’9". Note: Frame size is determined by measuring the distance from the center of the bottom bracket (the bolt that locks in the crank) to the top of the seat tube. Stand-over height is determined by measuring the distance from the ground to the top tube. A bike that you ride only on paved surfaces and never take off road should give you a minimum stand-over height clearance of 2", a bike that you ride on unpaved surfaces should give you a minimum of 3" of stand-over height clearance and a bike that you ride off road should give you a minimum of 4" of stand-over height clearance.
