After stripping a rear pin wheel I am looking for some 12mm REAR hex adapters for the b4/b44, but this also needs to be with 12mm hex rear wheels for the b4, as i only have pin type.
Don't mind if scratched / anodizing coming off etc along as they work.
Wheels can be with yellow mini spike schumacher's, really don't mind if scratched or dirty as long as they roll straight

.
PM me details and pictures.
Thank you
