Mine was going up a slope that was compacted snow and made into shiny ice.
People were walking down the sides of it on the snow. Went up the middle tyres gripped like Velcro. Tried to make them spin out but no go. Very impressed.

I fitted mine this morning and have just spent the last hour riding up the steepest, iciest hills I can find. 😀

Bloomin’ draggy on the road, mind!

Ordered mine Wednesday from next day tyres. Still waiting for them to arrive 🙁

I have a feeling the snow and ice will be history by the time they arrive. Rollers for me tonight 🙁

First proper ride on my Pros today, very good… Though is it just me or are they unbelievably tramliney when there’s ruts?
