Hope someone can give some input.
I'm in the process of having custom frame built. My current contact points – from a bike fitting several years ago – were given to the frame builder and from those measurements drawings have been submitted.
I've made a few changes during the process (namely to head tube height to save a stack of spacers beneath the stem) but Im not totally sure of the ST angle (currently 71.5º for a seat height of 775mm and set back of 95.5mm, with head tube angle of 72.5º).
The frame is year round rider so full mud guards with 28mm tyres can be fitted hence the slightly slacker angles.
Can some one confirm if this seat tube angle will equate to the said set back at that seat height???? Sorry if a little vague with info
