The B903 puts the bar and stem in one piece. It brings the familiar split-stem shape of an early mountain-bike cockpit to a modern 1 1/8 inch threadless fork, with no separate stem to choose.
Made by Nitto in Japan from chromoly steel, this is the 710 mm B903 in black. It is a different model from the wider B923. The fixed assembly makes checking your position before ordering especially worthwhile.
