hiya mate- Right I think I have for you. You know on the F crank, he left and fight are actuallt identical arms, just the right is drilled and tapped for the spider, and threaded for the lockring. You can still see the boss of the left crank. Well, I have a right crank, with no spider. It is NOS, still in the packet. It does have the lockring and bot with i thoiugh. You know this is hens teeth stuff, so I'm afraid it is gonna be £35 posted. I do have a lot of one off lefts andrights of RSRs and e cranks too, but not much in the way of pairs, and certainly no new pairs. Anyway, let meknowwhat yoy want. I can do a brand new pair of F in red for £70 too if interestd?
cheers mate,
