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. It's not as good as the ARB roller, but it has the same roller part as the original, so the balance is excellent, and it advances remarkably well. 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. We do not accept requests for discounts. Thank you for your understanding.
