The Service Course SL-70 is the bike fitter's go-to bar. The short reach to the hoods allows a proper fit without compromising stem length and steering control. With the revised ramp angle, proper fit is now achievable on even the most challenging setups. The 70mm reach is the shortest of Zipp's new Service Course bars. 128 drop. Whether it's a rider with a shorter torso or a bigger rider getting aero by pairing this bar with a long stem, this bar helps put just about any cyclists into his or her optimal position. The SL-70's flattened top provides a better fit to the hand and is clip compatible. Five sizes. 7050 aluminum.
