The SpeedDisc i19 offers race worthy weight (450 grams), and excellent strength characteristics. The disc-brake-only SpeedDisc i19 features WTB’s Global Bead Seat and eyelets, but lacks the I-Beam and Unbendium Bulge of the LaserDisc series.
WTB SpeedDisc i19 Rim 26'' Specifications:
Usage: Cross Country.
WTB SpeedDisc i19 Rim 26'' Technologies:
GBS: WTB’s proprietary Global Bead Seat design utilizes deeper grooves for the bead seats as well as two raised lips that lock the tire’s beads into place on the rim. GBS–featured on LaserDisc, SpeedDisc and Dual Duty series rims–holds the tyre firmly in place and greatly reduces the chance of “burping” the tyre off the rim in heavy lateral loading.

Rated 5 out of 5 by AlexK Looks good, check the valve type
The reason I write the review - this rim comes with the hole for PRESTA valve, not schrader as you may expect from cheap rim.
There's nothing more specific I can tell - bought this rim as a spare, so no real life tests were made. The rim makes good visual expression though - well finished and such.
The real weight is 449grams.
