After copping a massive branch to the shin a mate of mine stook pity on me and gave me a pair of 661 shin protectors, after a few months rehab I put them on and they have saved my now very ugly shins from yet more damage, chicks dig scars but sometimes not that many! they aren't the most expensive pads on the market but they do the job, as for rear protection they wrap around a fair bit so you should be covered. I'm just a dumb chippie who rides bikes but give them a go.
