Can't say as I've ever heard of that brand, but I'm in the US. I found that they're only $10 in NZ http://www.kiwivelo.co.nz/store/inde...product_id=754 (there was another google response that showed an Australian shop selling them for $39 called Cell Bikes). Might be particular to your area of the world, couldn't find a thing by trying varying googles with On-Air (bikes, components, etc). Does this shop specialize in cheap?
