Kids Ride Shotgun Pro Adapter – Trek Knock Block Used but fully functional Kids Ride Shotgun Pro Adapter for Trek Knock Block headset systems. The adapter has some light wear on the top surface from normal use. There is also a small area of cosmetic damage on one side (see photos). Neither affects its function. Removed from my previous bike and no longer needed as my new bike doesn’t require the adapter. Compatible with Trek bikes using the Knock Block headset system and intended for use with the Kids Ride Shotgun Pro child seat. You can also use this to delete the knock block system too, even if you aren’t using a shotgun seat. What you see in the photos is what you’ll receive. Any questions, please ask.
