Designed to give a precision response in deep going. Our longest stud - approx. length 25mm (excluding threaded section). Show jumpers love this stud to help with tight turns in a greasy outdoor ring. Take care: we do not recommend this stud for use on ponies, and would be cautious about using it on the inside due to the risk of striking the opposite leg - most users use a shorter stud on the inside in combination with this on the outside.
