Right, now I'm converting a bike (tandem) from flat bars to drop bars.
It has a stem on it (well not on it, it's on my desk) which, I think, is 25.4mm fitting at both ends (steerer and handlebar ends). It's a quill type which opens up, rather than the front coming off.
Now I have some shiny new handlebars, with no amount of coaxing are they going to fit them onto the stem, the radius of the bend looks tight, but the real issue is that they are 3T mutant bars with bumps at the bottom which are tight.
Now, the way that I see it is that I can either get a new set of bars with nice shallow drops, and scratch them to buggery to get them on the existing stem, if they will fit at all. Or I can get a new quill stem which has the front opening up like an A head (i.e. the front coming off) or I can get a quill adapter and fit an A head stem.
What I want to know is what size adapter and A head stem do I want? Can I get a quill which has the front opening up? I think that my bars are 25.8mm and my steerer tube is 25.4mm It's a bit of a mind field and I'm struggling to get my head around it.
