January 5th – A fiddly maintenance job this evening. Studded ice tyres currently fitted to my bike have small, very hard carbide studs in them to grip black ice. They sit in pockets in the tyre tread, and on the back in particular, if you skid on tarmac or brake very hard, they rip out.

Once I’ve lost ten or so, I delve into the spares box and whip out a small bag containing replacement studs, supplied by Schwalbe, the tyre manufacturer. 

By deflating the tyre and pinching the cavity, with pliers one can pop fresh studs in, using a drop of washing up liquid as a lubricant. Fiddly at first, once you’ve got the hang, it’s easy to do.

It may sound overzealous, but for the want of a couple of studs, you could slide. A stitch in time, and all that…
