thanks! just weighed it a couple of days ago when you ask me for the weight of the stem. the bike with hayes stroker rear brake on it ways 12.760kg. the rear wheel is a Halo SAS 26" rim laced on da bomb head spin 9speed hub and dt champ spokes, so yeah, when i finally saved up for two 26" Atomlab pimplite rims, a Hope Pro 2 Disc Rear 10mm Bolt-Up (if anyone know a lighter and better 9speed hub please let me know) profile cranks, this thing should under 12kg.
