Pumped the tyres up on my modded 406 SS R20 and the wife's 451 Magenta R20 with SA 8 spd for a nice Sunday ride.
Came out a few minutes later to discover I had over-inflated and burst my wife's front tube/tyre, (Stelvio), and I had no spares.

Some days you're not meant to ride.

PS: Nice find, Dynocoaster
