Schwalbe Big Apple 28″ Tyre – RaceGuardThe Big Apple started off the Balloon bike trend more than ten years ago: Comfortable cycling without using complicated technology! Air cushion tyres are used as natural suspension. Inflated to around 2 Bar a Balloon bike rolls really easily and with a full suspension effect. A normal tyre with a width of 37mm must be inflated to a rock-hard 4 bar, in order to roll similarly well.Features: Size: 28 x 2.0 ETRTO: 50-622 Execution: RaceGuard Compound: Endurance Skin: Lite Bar: 2.50 – 5.00 Bar (35 – 70psi) EPI: 67 Load: 135kg Weight: 740gBuy Schwalbe Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
