New for 2017, the Nashbar Carbon 105 Road Bike is your do-it-all, workhorse road warrior that can handle whatever endeavors come your way - be it races, fondos, spirited group rides, or simply riding for the pleasure of riding's sake. At its heart is a C5 high-modulus carbon fiber frame for an ideal combination of performance and comfort in an all-around competition-grade road platform. The C5 carbon weaving process translates into a frame that is incredibly stiff without adding unnecessary weight. The carbon frame features a BB86 bottom bracket for added stiffness and weight savings while the oversized chainstays and minimalist seatstays ensure a stiff platform for climbing and sprinting as well as comfort throughout long days in the saddle. The carbon fiber fork, with a 1-1/8 - 1-1/2 taper alloy steerer, is lightweight and ensures responsive, predictable handling. The Shimano 105 5800 2x11-speed components spec'd at the shift/brake levers, derailleurs, and cassette simply perform as well as their Dura-Ace and Ultegra peers without the hit to your bank account. Shimano 105 is the epitome of stuff that works - day in/day out, year in/year out, no matter the conditions at hand. A FSA Gossamer mid-compact crankset with 52/36 chainrings combined with the Shimano 105 11-28T cassette strikes an optimal balance for gear ratios to handle steep ascents, steep descents, as well as flatter roads with equal aplomb.
