I’ve snapped saddles before, but I’ve never thought “oh, I wish I’d thought to carry a spare one with me”.
Strangely, last weekend I went away and had fitted a new Brooks Cambium saddle during the week. I was so sceptical it wouldn’t cripple my bum for life I took a spare with me in case it was intolerable.
Despite feeling as comfy as a board when tapped, out on the bike it’s the comfiest saddle I’ve ever ridden!
