Good. Karma for trying to ruin the TdF with stupid faces
It may be meant as a joke, but it's a poor one.
Tommy rides for all to see the effort, which I am happy to see in contrast to some of the poker faces of the past. Someone who rides with his heart maybe more than his head, and the peloton needs characters.
A freak crash and painful as well. These are the ones which hurt the most and often cause (yet another) collar bone to go, or worse.
It could be that the cage had opened a little and the bottle was loose enough to fall out, this can happen and get a bit worse without being noticed by either rider or team mechanics. I know, it's happened to me but without the disasterous consequences suffered by Tommy.
The Tour of Belgium is actually a strange race, a combination of flat and windy plus "berg" stages with plenty of pave. Almost like an extended, multi-day version of RVV, and a hard race (as if any Belgian race is easy!).
