DT RWS Skewers
DT's RWS skewers combine the convenience of a QR skewer with the security of a bolt on. They are VERY secure, and easy and convenient to use. Just over 100g for the set, they allow you to get your quick release wheels locked into your frame and fork, giving more secure rotor alignment for disc wheels and generally making sure your pretty face stays just as pretty as it is. The skewer's design allows you to orient the handle independent of skewer tension, keeping the lever out of harm's way.
Price is per set, choose 130mm for rim brakes and 135mm for disc.
