ISC Tandem Pulley 50mm Wheel

The NEW Zipspeed Tandems represent industry leading Zipline Trolley innovation at its most affordable! The design of this mid-sized trolley uses state of the art engineering techniques to ensure that the Trolley will run and run! 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 minimise flex. We have also introduced a rubber brake buffer to help to absorb the impact at the end of the run. The main attachment point is large enough to accommodate a wide variety of Karabiners & 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") Wire and the centre redundancy axle is fitted with a colour coded collar, for easy identification.
