700c 28mm - Gravel-ish tyres

[Richard A Thackeray]

I run Marathons on my CGR ('28') & they cope with most things

Even to this extent
This is about as bad as I'll go

You can ride in a lot of places on slicks - as a teenager I did it without thinking about it! - but they will show limitations at some point. Otherwise CX riders would use slicks in dry conditions.

You can indeed!
I've ridden along the same route on Duranos, but with it not quite as bad

I've used a 'file' pattern CX tub, in dry conditions in years gone by
