Not so long ago I followed the crowd and changed a perfectly good set of tyres that I had no issues with.
Guess what I bought? Hans dampf for the front and a Nobby Nic for the rear.
My god it's an aweful set up for me! Way too much drag for my liking and more grip than I need. I can imagine I'd love them if I had ski lifts around me to ease the pain of squirming their draggy grippy knobbles up the trails and had a load more descending to actually get enough speed up so I can use the grip.
I've appreciated them on the odd descent in the Lakes and the Peaks but the rest of the ride has suffered for having them on.
On this one I have to say I shouldn't have followed the herd....
What are your sheep like mistakes?
