BBR worked with Elka Suspension to come up with a high quality, rebuildable, adjustable pitbike shock. The result is their brand new aluminum body Stage 2 playbike shock. A perfect match to our Stock Comp (or older generation Super Stock) swingarms, these Elka shocks feature adjustable rebound damping, adjustable preload, and a giant 16mm shock shaft. We had Elka valve these shocks for aggressive adult riders (and fast kids) and they're sprung for 165-200 lbs. riders.
