This evening I went over son no. 2's crashed Ridley with him, after last week's slide he had on something black and dark in the cold - either black ice or diesel.
He'd torn both shifters off their mounts, torn the bar tape on both sides badly, worn off the laquer on his 3T Aeronova bars (they've done 4 years of winter riding, so aren't new) and worn part of his Garmin off, damaged his saddle, the left pedal and part of the left shifter. That was the bike damage. He's intact but bruised and sore still.
We worked to remove the bar tape, get the shifters back on new mounts and add mini-TT bars for TT road training. Bar tape will go on tomorrow but the frame appears to come away without any damage. Which, given the damage elsewhere, was surprising.
