Bugaboo cam or frog.
Replacement foam only.
This will make your bumper bar as good as new.
Bit of wiggling an pulling to get foam on but takes 5 mins, rip old foam off.
Apply some washing up liquid inside new foams an they wiggle on, onceon they will stretch into place.
I have been selling foams for prams for years any question please ask.
Cheaper option rather than purchasing a whole new bumper bar.
These will not fit the cam 3 look at my other listing.
