Thank you for viewing. This is a self-made, flip-up, round roller Yaen L size. Length: 34 cm, Weight: Approximately 11 grams, Stainless steel shaft: 1 mm, Hook: Katsuichi Out Barb S (with barbs) Shimano's flip-up roller Yaen slides well and advances even at low angles, but the price is high, making me hesitate when deploying the Yaen. I use a self-made roller Yaen as a substitute. Although not as good as the ARB roller, it has excellent advancement because it balances with the same roller part as the original. Except for the roller part, I have copied the length, weight, and balance. The Shimano roller Yaen in photos 6, 8, and 10 are for reference only and are not included in the product. There may be some slight variations in the photos as they are reused. There may be some size variations due to being handmade. We do not accept requests for discounts. Thank you for your understanding.
