Handy to have a few spare as root starts chew them
Posted on 6th Nov
Rotostarts eat these for breakfast so even if yours hasnt started slipping yet, a spare one is a vital addition to your spare parts box. Fitting is a piece of cake but dont be fooled into lubing these up to much when you put them on - its normally stray oil / grease that causes them to slip in the first place!
