Small in stature, and big in heart — just like your little boy or girl. Inspired by their Grand Tour-winning Madone, Trek's KRX is a race-worthy steed, destined to propel your preteen to the finish line faster than ever before. Its zippy Trek Alpha aluminum frame is quick and nimble, and with 26-inch aluminum wheels, this dialed-in rig is race-ready. Whether your little champ is looking to go far, fast, or both, the smooth-shifting, wide-ranging 18-speed Shimano Sora drivetrain is up to the task. Sure-stopping cantilever brakes with secondary bar-top levers inspire confidence, while the kids-specific seat and Bontrager stem, bar, and seatpost just might make you jealous.
