You can tell that the folks at XLAB have probably spent a lot of time on their bikes. Is there a helpful accessory they haven’t figured out how to make? The XLAB Aero Cage Optimizer seems to be proof that if there is a problem, they will try to find a solution. Frame builders generally try to do their best to cater to the greatest number of body types, but once the bottle cage bosses have been drilled, the riders just have to work with their placement a best as they can. With the XLAB Aero Cage Optimizer, you can now adjust the cages to sit exactly where you would like them. It can mount any place that a bottle cage can, so if you want to adjust where your cage sits on your frame, your rear hydration carrier or even your aerobar hydration system, the Aero Cage Optimizer will fit. You will be able to adjust your cage up or down by as much as 1.75 inches. The XLAB Aero Cage Optimizer comes with aero cage optimizer plates, three sets of different length screws, a set screw to secure the plate position, Nylock nuts to secure the plates to Torpedo Mounts, and black spacers to make it all look great and professional. The whole set up only adds 30g to the weight of your bike, but will add oodles of practical comfort.
