I think I may have bought a G4 too, but I didn't really want one because they get slated due to the new clamp design. I thought it was the G4 I was taking a risk with not the G3. Seller says they're going to post new bolts out asap. I wonder if they're a bike shop?
I think there's a load of ST ones listed as LT.
Cane Creek website sells the elastomers, properly labelled and matching them up the best way I found to identify what's what.
Pretty sure that one's a G3 ST.
The one I got is a G4 ST, I think the50mm travel will be enough for me.
