It's time to change your riding Protocol with a full suspension mountain bike that's ready for the trail. Introducing the 27.5" Schwinn Protocol 2.7, also known as your new weekend warrior. This souped up MTB sports an aluminum dual suspension frame with a powerful Schwinn suspension fork for soaking up all the bumps and thumps in your path, and strong mechanical disc brakes for crisp all-condition stopping. 21-speed trigger shifters mean every hill and path are yours for the taking. Toss in extra wide double wall alloy rims for added durability, 2.25" wide knobby mountain tires, and a durable Schwinn alloy crank for premium gearing, and there's nothing the Protocol 2.7 can't handle. All it needs is a rider... Like all Schwinn bikes, the Protocol 2.7 comes with a limited lifetime warranty for as long as you own the bike. Enjoy the freedom of riding a Schwinn.
