Thank you for viewing. This is a set of two self-made, flip-up, drum-shaped roller Yaen (0.8 and 1). Length: 34 cm Weight: 0.8 size weight (approx. 10g), 1 size weight (approx. 11g) Stainless steel shaft: 1 mm, Roller part: 0.8 mm Hook: Katsuichi Out Barb S (with barb) 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. Although not as good as the ARB roller, the balance is the same as the original roller part, so it advances excellently. Except for the roller part, 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. The photos are reused, so there may be some slight discrepancies. I am not accepting requests for discounts. Thank you for your understanding.
