Control tech vs controlstem dating dilemma

[Commanderrb]

I was going to post a picture but figured if you answer this you’ll not need one, anyone any idea when the control”stem” branded stems swapped to control tech branding. I’ve one of each and want to get it broadly period correct on latest build.

Good question, unfortunately documentation about Control Tech is rare.

At BikePro they had pictures with 1996 copyright print of both, Control Tech and Control Stem labeled stems.
http://www.bikepro.com/products/stems/contech.htmlBut maybe those pictures are outdated or not from 1996.

Other documenation show ealier also just Control Tech logos any longer
e.g. this buyers guide from 1994


Maybe Mombat could be the source of information.
They miss a detail page about Control Tech, but their parts history section
http://mombatbicycles.com/MOMBAT/BikeHistoryPages/Timeline.htmlIs listing for 1991 and 1992, Control Tech "Control Stem" stems, for later years just "Control Tech" stems

Incredibly helpful thankyou, on the basis of those links I think I will leave the control stem on the ‘90 bike it’s on and put the control tech labelled one on the ‘94 build underway ( or buy a better one as it’s hammered). Brill
