Hi All I am building my first trials bike it is an old 2002-2003 T-MAG, the forks I have with it have a really long steerer tube. My first question is how many mm of shims would you cut the steerer to suit, bearing in mind I will want to do a fair it of trial and error with regards stem height. My second question is I have a pair of Try All Flat bars with a Try All Nuc 30 degree 150mm Stem, is this ok with regards length and angle, or would you recomend something else??? Many Thanks In Advance Tom
