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 Yaen (approx. 10g), 1.0 Yaen (approx. 11g) Stainless steel shaft: 1 mm, Roller section: 0.8 mm Hook: Katsuuichi Out Barb S (with barbs) Shimano flip-up roller Yaen slides well and advances even at low angles, but the price makes me hesitate when deploying the Yaen. I use my self-made roller Yaen as a substitute. Although not as good as the ARB roller, the balance is the same as the original roller section, so it advances excellently. Everything except the roller section, such as length, weight, and balance, is copied. The Shimano roller Yaen in photos 6, 8, and 11 are for reference only and are not included in the product. The photos are reused, so there may be some slight discrepancies. We do not accept requests for discounts. Thank you for your understanding.
