WB200 Bike Mount
If you run the S53 bars this is mount you want. It is sexy, aerodynamic and well built. It complements the S53 Whispbar. Why have such nice aerobars and mount a hideous rack on it. The 15MM adpater attachment is slick and actually is secure despite how it appears.
Yes it is pricey, but if looks, performance and true compatibility are important to you then this is the rack.
I ordered another one and sold off my Inno mount.
