Surly Preamble Drop Bar Bike Nothing More is Needed Gravel bikes continue to grow in popularity as they are truly a one-bike-does-all type of bike. These bikes are perfect for riding on the pavement and tackling those fun gravel grinds. The Surly Preamble Drop Bar Bike is a pavement and gravel utility worker that proves you don't need to cut corners or clip coupons to make a more affordable steel bike. You just need to keep stuff simple. The Preamble can run racks and fenders and carry a couple of water bottles. Smooth and efficient on asphalt, the Preamble's double-butted main triangle provides a resplendent ride feel and withstands abuse from life's inevitable potholes. This version of the Surly Preamble comes with a Micro SHIFT 9-speed drivetrain. With a 40T chainring up front and an 11-36T cassette on the rear, you'll have no issues cruising the bike paths or tackling those longer rides with all your gear. Avid BB7 mechanical disc brakes provide reliable stopping power on the pavement and in the dirt. 21mm aluminum rims are paired with Kenda Kwik Tendril tires that roll smoothly on the road but can also take you on hardpack dirt surfaces.
