The Torelli Bormio stem weighs approximately 155 grams in the 12 cm length. It is produced using the state of the art tri-dimensional (3D) forging process that yields a far stronger and lighter piece than previous fabrication systems such as extrusion and other older forging methods. Our stem graphics allow for reversing the stem for a greater rise.
Rise: 6 degrees, 17 degrees or 35 degrees
Lengths: 8, 9, 10, 11, 12, 13 cm measured along the center line of the stem. I note this because Italian stems are usually measured across the top of the stem and this can yield a 1/2 cm length difference. The 17 and 35 degree stems do not come in the 13 cm length.
Clamp diameter for bar: 31.8
Made for 1 1/8" steering tubes but an optional shim is available for 1" steering tubes.
The bar clamp bolts are a big 28mm apart to give a firm and rigid bar/stem assembly. An optional titanium bolt set can be ordered for the Bormio stem. Ti bolt kit suggested retail: $29.95
Stack height: 4 cm
Assembly torque specs
Handlebar clamp bolts: 5 nm
Steering tube clmap bolts: 4 nm
