Originally released in 1993, the Challenger frame and fork kit was conceived in a golden era of BMX when racing and trail riding could be done on the same bike. It quickly became one of the best-selling frames ever… and now, 30-years later, it's back! For this very limited-edition reproduction kit, S&M have gone with a 21” top tube, upgraded to a CNC-machined head tube and laser-cut drops. A 1” threaded headset and 1” seatpost clamp are included with each kit. ###section### Product Specs MATERIAL: Chromoly HEAD TUBE ANGLE: 74.5° SEAT TUBE ANGLE: 71° CHAIN STAY LENGTH: 14.25" BB HEIGHT: 11.6" WHEEL SIZE: 20" STANDOVER HEIGHT: 9.25" DROPOUT SIZE: 10mm HEADSET TYPE: Integrated BB TYPE: Mid BRAKE MOUNTS: Brakeless GYRO TABS: None WEIGHT: 6lbs (2.7kg) ###section### Product Highlights Neutral geometry for responsiveness and stability Best suited for Trails and riding Fast High-quality Chromoly construction Made in the USA Strong and durable dropout ###shogun-image-section###
