big apple k-guard

The 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, with a similar effect to full suspension. A normal tyre with a width of 37mm must be inflated to a rock hard 4 bar, in order to roll similarly well. * Dynamo Compatible: With dynamo ribbing for extra grip. * K-Guard: protection layer reinforced with Kevlar fibres. The protection standard for every tyre from the Active Line. * Balloon bikes: Air suspension built-in. * Performance Line: Excellent quality for intensive use. These are the best value for money tyres. **ETRTO:** * SCC017: 55-622 * SCC018: 50-254 * SCC029: 50-203
