Good service

I visited Peloton&Co today in Spitalfields to take part in the Kask amnesty offer (you trade in any helmet and get the Vertigo, usually £165, for £100.) I'd never heard of the place but it's a really nice little cafe with good food and even better beer. However, the best part about it is that they let me keep my current Kask helmet! So I didn't even have to trade anything in. Two thumbs up from me.

Can it be ANY helmet? or does it have to be kask?
