What stem lengh are most of you using. I ride a 05 16" Reign 2 and have a long travel Lyric fork on it. I was wondering if I should get a shorter stem and how that would effect the setup. I ride aggressive trails pretty much all downhills but need to earn them too. I, up until recently have been running the factory 90mm stem but have borrowed a 70mm was is still ok. Wondering what the advantages of a shorter stem are and whether I should go for 60-65mm or something. What you think?
