No offence intended RikiRiki. Cannondale King was having an extremely generous day which, I hasten to add, I missed by a matter of mere moments :cry:
As to a price, it's hard to say. Cannondale Kings pair were the only ones I've seen for sale on here. XT IIs usually make good money and are actually quite common it seems.
I'm serious about these being the shifters to have if you're running a 6-speed rear. (Don't remember if they'll index on a 7-speed cassette).
Perhaps look at the average cost of a 7-speed set and try them at that price.
