SHIMANO YUMEYA Custom Spool 4000M

AR-C Spool
A lightweight spool made with Shimano's unique processing technology to achieve the two goals of "no trouble" and "increased casting distance". The special shape of the spool ring creates a "line straightening effect" that allows the line to be released in the best possible condition.

S A-RB
The A-RB is the industry's first bearing that uses "surface modification" to form a "passive layer" that repels rust. In addition, the SA-RB seals the sides with a rust-proof material, greatly reducing salt buildup caused by salt recrystallization inside the bearing.

Seawater OK
Shimano's unique high-performance bearings, S A-RB and A-RB, which repel rust, and the exterior are treated with anti-corrosion, so you can use it safely even when fishing in the sea. We recommend washing it in the shower after use to ensure long-term comfortable use.
