The one piece aluminum Unibutt is precision machined so the pin-plug, gimbal, fixed hood and ferrule are in perfect alignment with the guides. A Teflon O-ring at the ferrule assures a snug fit, keeps out moisture and prevents corrosion. The hoods are custom anodized in Shimano Tiagra gold and the curved Unibutt increases your leverage by as much as 30% while in a fighting chair.
