ATACS = happy knees
+1

Older atacs = super happy knees.
+1 also.

I'm pretty sure anyone on this thread would give their first born for a pair of old atacs - me never used em.
No kids but I have a nut I am not doing much with.

They still come up on Craigs/kijiji/e-bay...always pretty cheap and some of the best sealed, most durable pedals I have ever owned. The copious float and lateral movement is the icing on the cake.
I own 3 sets and don't think I will ever need pedals again.
