Today, I be mainly playing musical front wheels/tyres. Bear with me, there was method in the madness, not madness in the method!
I took the Campagnolo Neutron off my CAAD 5, the Campagnolo Proton off my DIY 6-speed Specialized, and the Mavic Aksium off my old Basso turbo bike.
I took the Continental GP 5000 tyre off the Neutron, the good Michelin Lithion off the Proton, and the worn Lithion off the Aksium.
I put the GP 5000 tyre on the Proton, the Good Lithion on the Aksium and the worn Lithion on the Neutron.
I put the Proton wheel on the CAAD 5, the Aksium on the Specialized, and the Neutron on the Basso.
This was all triggered by a stupid decision to ride my best bike all year round, a few years back. All of the bikes have rim brakes. One winter of riding on wet salty/gritty roads was enough to grind away a lot of the braking surfaces of the Neutron. I didn't want to scrap the wheel so I kept on riding it, but seeing photos of rim failures finally decided me - I definitely do
NOT want my front wheel exploding on an 80+ km/hr Pennine descent!!
So now I have my best (but now fragile) wheel safely on my turbo bike, my second best (but still good) wheel on my best bike, and a chunky (but acceptable) wheel on my knockabout bike. All bikes still have the same front tyres as before.
