What are the options for a single ring set up with specialized cranks?
I wished I could have been able to use carbon ti x mono-ring, but realized that it would not fit in. Chainstays are few millimeters too wide. So I have go with spider that will move the ring outwards.
Specialized spiders, a bit heavy and expensive?http://www.mbr.co.uk/wp-content/uploads/2012/07/12e180080.jpg
is that road 110 bcd?
Lightning reversible spider, where to buy?
EP Mattias custom made? XX1 spider would most likely have a similar chain line problem like x mono-ring.
