The Zipspeed Tandems are fitted with rubber sealed, deep groove bearings for optimal performance and a lifespan of several thousand miles/km. The side plates are made from Aerospace Grade 7075 Aluminium, to minimize flex. We have also introduced a stopper to help to defend the trolley frames from impact during end-of-line braking. The main attachment point is large enough to accommodate a wide variety of carabiners & Snaphooks. There are extra attachment holes for a secondary lanyard and a small central hole which can be used to fit an accessory (handle bar etc).
We offer versions for 13mm (1/2"), 16mm (5/8") or 20mm (3/4") cable. The centre redundancy axle is fitted with a colour coded collar, for easy identification.
