Terrible news.
As someone who has been a mountain biker for the last 7 years and started road biking in the last month it really is a stark contrast how potentially dangerous it is compared to MTB.
On a 28 mile ride on Tuesday not only did I manage to fall off, doing more damage to myself than I’ve done in 7 years MTB, I also encountered 2 cars cutting me up and an HGV driving very erratically maybe 1-2m behind me.
You need to have your wits about you all the time and it doesn’t matter how good a rider you are, even the smallest lapse of concentration can result in an accident. This is of course the same in MTB but the difference being trees, rocks etc don’t move; on the road you simply can’t account for what other road users are going to do.
Hopefully Nicky will make a reasonable recovery given his injuries.
