Canyon Dancer Bar-Harness II (X-Wide/36) (Black) Makes use of heavier thread with more stitches in the pattern for greater strength and the contrasting thread color aids in detecting flaws or damage. The cross straps are held farther away from the switch gear. The "cups" eliminate possible damage to grips. The new cups hold the cross straps and your tie downs further out on the bars to better clear a wider variety of fairings. The new cup is even easier and quicker to install correctly.
