Hey guys, I was looking around on ebay and found these: http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA%3AIT&rd=1

Has anybody ever dealed with these cranks? I know Corratec is a european company and isn't well known in US so I couldn't find any info. I am mostly interested in weight, but anything else that's worth mentioning would be greatly appreciated.
