Which has had me wondering what type of bird would just die and get mashed up and what would send you flying over the handlebars at 25mph? where's the crossoverfrom dead tweetiepie to no front teeth and road rash city? So far I have (based on a Road bike):
Magpie and bigger = no teeth and road rash
Blue Tit and smaller = mashed, dead and rider probably maybe stay on the bike.
Somewhere in the middle there must be a crossover, what about a blackbird? what would they do?

bonj said:Let's ask ourselves how fast the bird would have to have been flying to live.
if the bird flew through at the widest point i.e. the circumference which we'll assume is 27" and a 16 spoke wheel, then it had a gap of 27"/16 = 1.6875" = 42.8625mm to get through.
assuming 20mph, then this is 8.94 metres per ssecond, or 8940 millimetres per second.
This means the bird had only 8940/42.8625 = ~a 200th of a second (5 milliseconds) to get through.
If the bird is, say, 100mm long, then it must have covered its own length in that time, so it must have been flying at 0.1m/0.005s = 20m/s = 44 mph, which is JUST feasible, but it would have had to have been lucky.
Any more than 16 evenly spaced holes in the rim, if dellzeq was going faster than 20mph, or the bird flew through at the centre of the wheel rather than at the edge, then it would have had to have been going even faster.

Wigsie said:A fine theory Bonj, but have you seen Dells Spoke set up? Pics of the Colnago were on a different thread and they are definately bird friendly (at pretty bloody sexy for spoke arrangements too)
