Description
The Norcross EX is that bike. The monocoque frame is powerful and sure footed because of the oversized BB and head tube which houses the full carbon tapered steerer tube, just like the one Jonathan Page raced all of last season in places he can’t pronounce either.
The Norcross EX features BB30, a tapered head tube and steerer and better mud clearance than last years frames. The EX frame is roughly 100g heavier than the SL model, so still plenty light.
Frame: Constructed with Aerus Composites 20T high-modulus carbon fiber and BB30 bottom bracket shell, oversized tubing for superior stiffness and tracking, 1 1/8 - 1 1/2 inch tapered head tube, slightly taller head tube than Norcross SL, FSA Orbit C-40 CX 1-1/8 inch top bearing, 1-1/2 inch lower bearing integrated headset included
Fork: Aerus Composites C4CX Carbon Cross fork 1-1/8 - 1-1/2 inch tapered steerer tube
