f'iz:ik® saddles offer a wonderful accessory slot attachment that seems to be woefully underutilized. We saw the need years ago and began prototyping various ways to mount lights to it. Eventually we designed our first universal mounts and offered them for sale as a DIY part on Shapeways. We continued with that effort, and can now offer even better mounts for f'iz:ik saddles.
Our new mount has been improved in a number of ways, and we now offer both a secure screw attached mount, and a convenient clip-in mount. We have made the mount thinner and more streamlined, and also made if slightly lighter and more durable. The 5th generation mounts are also slightly longer, to accomodate small saddle bags without requiring the extension.
Pick a mount style - either the secure or clip-in type.
Attach the desired arm that will hold your desired accessory.
Attach the mount to the saddle, and clip or screw in your accessory to the mount arm.
