RARE '90's Ringle' 3DV Purple Ti-Stix Combo Seatpost Collar w/Ti-Stix Lever - EC

Description

Vintage '90's Ringle' 3DV (violet/purple) "Ti-Stix Combo" Seatpost Collar with Ti-Stix Lever.
This is an original Ringle' part from the early '90's.  It is in excellent condition (see photos).  This one was listed in the catalogue as the smaller of the 3 sizes that were available (for 1-1/8" size seat post).
The internal clamp diameter of this Ringle collar at the bottom end that goes around the seat tube measures aprox. 28.7mm and the internal clamp diameter at the top side with the internal bead is aprox. 26.6mm.  The inside bead on top of the clamp keeps it from sliding down the seat tube (Photo #5).  The measurements were taken in the all the way open position and will get smaller as the collar gets tightened.  Please don't hesitate to message me with details of your frame's seat post and seat tube measurements so we can make sure it fits.
The collar itself has seven 8mm drilled-out holes.  The quick release is a standard cam-twist except that the side opposite of the lever tightens as it threads into the collar. The threaded rod is made from grade 5 6AL-4V titanium. Complete part weighs just 43 grams.
