Schwalbe is coming

These have spent more than a year atop various cupboards, awaiting their intended weather, but as it ought to be here by the end of the week and I had a spare evening I finally got round to fitting them. I'd gone for the narrowest possible but there's a lot of space between the tips of the studs and the mudguards, so I may well see if these can be squeezed into the normal bike so that fatter tyres with more studs can go on this one.
