These are made in hi tensile steel to make assembly of the SIP tubeless wheel rims much safer. Price is for one stud - 4 required per rim.
(SIP Lambretta tubeless rims come with very poorly made extended hub studs and later the versions are in stainless steel which are not strong enough or long enough. )TIP - Do not use with AF tubeless rims as they use standard length screws.
