The Asher Pacey 5.59" twin fin set comes with a stabiliser. Use the stabiliser when the waves get bigger or if you want more drive and stability. This set has purely been inspired by Asher Pacey's progressive, yet stylish twin fin surfing. They perform well in all conditions and deliver maximum drive, speed & hold through turns, whilst maintaining a lively, free flowing ride that is iconic to twins. This set of fins is recommended for twin fins with a pulled in tail.
