Modified G3 Onyx brakes which double as a heel pad. See http://www.lornecameron.com/2013/plu...inding-brakes/ . I wanted to put them on inserts this year so I could take them off for +1000m days to save a bit of weight, but test installations didn't go perfectly and I'd be totally screwed if I fucked them up, so I left them as-is. Brake deployment seems much better now with Vulcans - I'll update the blog post soon.
