The Midnight Special is an endurance road bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement. It excels on pot-holed, deteriorating pavement and the occasional long stretch of gravel. The Midnight Special’s 700c tires eat up road chatter and absorb all the bumps in the road for a much more comfortable ride. - 100% Surly Chromoly frame, main triangle is double-butted; 1-1/8" threadless Chromoly fork- Rack, fender, and three sets of water bottle mounts- Flat-Mount disc brakes- 44mm head tube- Tire Clearance: 27.5 x 2.35" (w/o fenders), 700c x 42mm (w/o fenders), 650b x 50 (w/ fenders), 700c x 38mm (w/ fenders) Frame Midnight Special Fork Midnight Special Steel Rims Alex Adventurer 2, 700c, 32h Hubs Novatec Spokes DT Swiss Champion 14G Tires Teravail Rampart 700 x 38 Light and Supple casing Bottom Bracket Shimano RS501 Crankset Shimano RS520 Chainrings 50-34T Shifters Shimano R7120 Front Derailleur Shimano R7100 105 Rear Derailleur Shimano R7100 105 Cassette/Freewheel Shimano R7101, 11-34t, 12-spd Chain KMC X12 Brakes Shimano R7170 Rotors Shimano RT26, 160/160, 6-Bolt Brake Levers Shimano R7170 Handlebars Salsa Cowbell Tape/Grips Black Cork Stem Promax DA-296 Headset Cane Creek 40 Seatpost Promax 27.2 x 300 (offset on 54-64cm) Saddle WTB Volt
