Taking our BMX heritage and combining it with modern MTB technology, the Avenger is perfect for smashing it down singletrack on the weekend or just getting from A to B in style. With an injection of aftermarket parts from Shimano, WTB, and FSA, the Avenger is also stacked with some very special components we designed specifically for this bike based on some of our favorite parts from our mid-school BMX roots. The full chromoly frame, fork, and bar keep the Avenger tough and agile, while the larger 27.5" wheels with 2.30" tires allow you to tackle any terrain in your path. We spent a lot of time on the Avenger this model year and we couldn't be prouder of what we created; A bike that is as fun to look at as it is to ride. If you're looking for the ultimate weekend machine, look no further!
