This could be me being very thick but when I set up my saddle on a new ITM Milenium stem I ignored the angle marking and used the heath robinson approach of a book on the saddle and a woodworking spirit level to ensure a very slight upward tilt. This left me with a slightly negative reading against the angle markings on the seat stem so I remeasured constantly to ensure my approach was correct. Over the past year though I am not so sure. I feel as though my weight is being forced too much towards the bars despite the seat being positioned well back on the seat post. I am very comfortable on the drops but on the tops it is a bit too tiring on the shoulders. I have been comparing the position to another bike I have which is more comfortable and the only difference I can find is that I have the seat slightly lower ( 3 to 5 mm ) on the more comfortable bike. I am not sure this is the major difference though and wonder if my approach to measuring the seat angle is just inaccurate and it is by fluke I have got it right on the more comfortable bike. Opinions please.
