Last week’s Tire Juggling post got me thinking about our collection of bicycles and their tires. We currently own five bicycles, one tandem, two road bikes and two mountain bikes. Every one of those bikes have different size tires on them. Our tandem has 26″ tires. My mountain bike because it has a large size frame it is mounted on 29″ tires and Donna’s being a size small frame came with 27.5″ tires. My road bike has 700c tires while her road bike has 27″ rubber.
Whenever we go for a mountain bike ride I carry two different size spare tubes and trust me, those 29″ & 27.5″ MTB tubes are big. At least with the road bikes, a 700c or 27″ tube will work with either size size and for the tandem a 26″ tube is all it takes.
If 5 bikes sounds like a lot for two people, ha, at one time in the 90’s we had seven. We had a pair of dedicated club ride road bikes and a pair of road bikes set up for commuting to work. We had a pair of Bridgestone mountain bikes and a Santana Sovereign tandem. But those 7 bikes required only 3 different tire/tube sizes, the tandem and road bikes were on 700c tires, the commuting bikes sported 27″ tires and the mountain bikes rode on 26″ tires.
