I'm looking to buy a 15 degree or larger 90 to 100 mm mtb stem in a 31.8. Easton site says they make on in a 20 degree but I can't seem to find one. Thompson's 15 degree are for the 25.4 handlebars. Maybe bontraeger, I think they have a 17 degree. I just haven't been able to find a 4 bolt front cap upperend stem yet. Can anyone help with a link?
