Choose your model. The SO or the WA.
Easy to Install:
SO: Just remove your seatpost and slip it on. The snug fit keeps it in place.
WA: Wrap it around the seatpost and secure it with the nut and bolt.
One frame number holder
One 4mm stainless steel socket head bolt
One #8 stainless steel nylon insert lock nut (the nylon insert keeps the nut from vibrating loose, no need to over tighten).
For replacement nuts and bolts use the Next Gen Spare Nut Pack.
A word of caution when placing your bike on a roof rack with a frame number attached.
