That was me. It was however on the steep section of the Angliru but I'd already had 4 uneventful days including the Lagos de Covadonga and the Alto del Gamoniteiro. Also no issues in the UK in 18 months. Summary, the Angliru is an extreme test but high temp blow outs can happen.I also had a moment of fear during the night, recalling it being posted on here, or perhaps on the BR forum about someone having the Ridenow tubes blowout on them on a descent - and of course this is a rim brake bike.
