Built for Blasting
Running this stem in a 55mm with 720mm bars on a '09 Heckler that I ride as my do-it-all, aggressive trail bike. Stem feels stiff, although not the lightest (but I wasn't really concerned with this).
Swapped to this from my slammed Easton Havoc stem that felt a bit too cramped. Happy medium between control when you're blasting and having room to stretch out on the pedally bits.
