Fed up with being shouted at by irate drivers, annoyed with the barrage of nasty comments on Twitter from cyclist haters, sick of people telling you to pay road tax?
Rejoice in their negativity and ignorance by getting on your bike and wearing an 'Upset the idiots' t-shirt, but get one before 30 November or you'll miss out.
The t-shirts were designed by CDF supporter, Stewart Pratt.
They're reasonably priced at £12 for an adult tee and £11 for the kids version. £5 from every sale is donated to CDF.
If you're still reading and you haven't yet clicked through to buy a t-shirt, here's one last reason for getting one - there are only four weeks til Christmas and those gifts won't buy themselves!
