Swings and roundabouts

What you lose on the swings you gain on the roundabouts.
- Gertrude Lawrence, "A Star Danced"

I fitted a new seatpost and seatpost clamp last week. As well as looking frankly excellent, they gave me a weight saving of about 85g. Not much, you might say, but then the old seatpost was carbon, so I wasn't expecting too much ... although 85g is nearly two KitKats, so not too shabby.

However, last week I also replaced my quite worn and suddenly very puncture-prone Fusion 5 Kevlar Pro Tech tyres with a pair of folding Continental Gatorskins... and they added 70g.

Gah...
