I’ve measured my old MTB. I think it’s a 19″ frame with about 22.5″ top tube, and it has a 130mm stem with flat bars.
Perhaps the frame is smaller than 19″ – it’s a Saracen, and I’m not sure if it’s measured to the top or centre of the actual top tube, or to the top of the seat tube (which extends above the top tube by an inch or two).
I put the cranks in line with the seat tube and measured from the top of the lowest pedal to the top of the saddle, and got around 930mm. I wasn’t able to sit on the bike, but I think the saddle might need to be raised a bit for my ideal saddle height.
The bars are quite low in relation to the saddle, and I remember it putting pressure on my hands, and also of feeling nervous on descents.
If I wanted higher bars, other than fitting a stem with more rise, would I need to look for a larger frame? I quite fancy a bike of similar vintage, but perhaps they’ll all have the same riding position.
Do modern bikes have taller head tubes?
