Thank you for viewing. This is a set of two self-made, flip-up roller Yaen (0.8 and 1.0). Length: 34 cm Weight: 0.8 size weight (approx. 10g), 1.0 size weight (approx. 11g) Stainless steel shaft: 1 mm, Roller section: 0.8 mm Hook: Katsuuichi Out Barb S used Shimano flip-up roller Yaen slides well and advances well even at low angles, but the price is high, making me hesitate when deploying the Yaen. I use my self-made roller Yaen as a substitute. It's not as good as the ARB roller, but it has the same roller section as the original, so the balance is excellent. Except for the roller section, I have copied the length, weight, and balance. The Shimano roller Yaen in photos 6, 8, and 11 are for reference only and are not included in the product. There may be some slight variations in the photos as they are reused. We do not accept requests for discounts. Thank you for your understanding.
