RIO Micro Swivel
RIO’s Micro Swivels are the perfect accessory for reducing line twist when casting large, wind resistant flies. Adding a swivel between the tapered section of your leader and the tippet allows the tippet and fly to spin without twisting the rest of your system, resulting in smooth, tangle-free casting all day long.
Swivels are also useful in long indicator leaders used in stillwater. By adding a swivel, the angler can add weight and also create a stopper for a dropper leg and fly to rest on after a fish has taken the fly.

I’ve used the micro swivel on windy days and it makes a huge difference in casting smoothness. No more tangles when using long leaders or heavy flies. Easy to attach and durable.

Works well with my indicator setup in a calm lake. The swivel holds the dropper fly in place after a strike and prevents line twist during casting.

Perfect for my fly fishing trips. The black nickel finish looks professional and the swivel stays secure under pressure. No slipping or wear after several uses.
