Hi there,
I’m supposed to make old school style shifter lever attachments (pivots?) located on a downtube. Is there somewhere a general specification for that (I did search but with no result)? It’s also possible that I don’t know the proper english term for that… thanks
Are you using the downtube shifter bosses like these?
I’ve used 75mm away from the headtube for the location along the DT

Thats the thing I’d like to use! need to make them as ordering them overseas is not the best idea for me. “Downtube shifter bosses” is the phrase I did not know and the thing I need the dimensions for

Don’t you know http://framebuilding.com — the european dealer for us? Well, ok, european, hmm, in the UK …
I know, but UK is no longer EU so buying there is not the best deal.
Oh, maybe we should make a list of EU located resellers and producers?
You can get the dorm tube shifter bosses at reset-racing.de, list point 4_Kleinteile_Stahl. Clicking will produce a PDF. In german they are called »Schalthebelsockel«.
I was told that the tips of the shifters should be inline with the tip of the down tube lug. It’s purely about aesthetics though.
But if you’re making a frame without lugs, then you don’t have a point of reference. In that case, put them on the butted end of the tube where ever it looks good to you.
