Daiwa 27 Zillion SV TW 100: What’s New in the First Full Change in Six Years

minagiman

Daiwa’s Zillion SV TW has long been the reel Japanese anglers recommend as a first baitcaster. Now, after six years, it gets a full model change. The new 27 Zillion SV TW 100 still weighs 175 g — but the brake, body and gears are all new. Here is what changed compared with the 21 model.

Release: December 2026 in Japan. Daiwa calls it a “super versatile” reel for every bass style, and it is salt-rated for seabass and rockfish too.

Key features

SV BOOST-I — a new brake, a first for Daiwa. Daiwa analysed the braking-torque data of the digital INTELLIGENT MAGFORCE brake in its IM Z reels and recreated that behaviour in an analogue brake. It keeps the SV concept’s easy, backlash-resistant casting while adding distance and better carry at the end of the cast, with less noise thanks to improved AIR brake parts. No batteries, but borrowed digital smarts.
GRAVITY BALANCE BODY. A new Infinite Stopper about 38.8% thinner and a thin aluminium gear side plate allow a shorter gear shaft, bringing the handle knob 4.6 mm closer to the reel foot. Weight stays at 175 g, but the balance improves palming, casting accuracy and retrieve stability.
Solid pinion. A solid pinion replaces the hollow one; at the same diameter and ratio it is over 20% stronger.
Tapered TWS. The level-wind opening is about 31% wider, with a DLC coating for smoother line release.
Oil injection cap. The sub-brake (Zero Adjuster) is gone; instead you can oil the pinion bearing yourself with the supplied tool — handy for saltwater users.
New thinner ZAION star drag with UTD drag and a drag click.
HYPERDRIVE DESIGN gearing keeps the Zillion’s trademark tough, smooth wind.

27 vs 21 Zillion SV TW

	27 Zillion SV TW 100	21 Zillion SV TW 1000
Brake	SV BOOST-I	SV BOOST
Body	GRAVITY BALANCE BODY (handle 4.6 mm inward)	Previous body
Level wind	Tapered TWS	TWS
Pinion	Solid	Hollow
Sub-brake	None (oil injection cap)	Zero Adjuster
Gear ratios	6.3 / 7.1 / 8.5	5.5 / 6.3 / 7.1 / 8.5
Weight	175 g	175 g
Spool	34/24 mm	34/24 mm
Max drag	5 kg	5 kg

Weight, spool size, drag and line capacity are unchanged; the upgrades are casting (brake), handling (balance), strength (pinion) and maintenance. The 5.5 low-gear option has been dropped.

Which gear ratio?

Gear	Line per crank	Best for
6.3	67 cm	Crankbaits, spinnerbaits and other moving baits
7.1 (H)	75 cm	All-round — the first-reel choice
8.5 (XH)	90 cm	Texas rigs, flipping, and salt use where fast slack pickup matters

Other Daiwa options

26 Zillion TW 150: 36 mm spool, 215 g — better for heavy lures and long PE casts.
25 Tatula SV TW 100: same SV brake family at less than half the price.
24 Steez SV TW 100: the flagship — lighter and more refined, where the Zillion is about toughness.

Minagiman’s take

Versatile reels often end up “good at everything, great at nothing”. The Zillion became the go-to by being tough. The 27 model keeps that character and quietly upgrades casting, feel and strength without adding weight — a great update for people who already love the reel. If you want a low gear, though, grab a 21 model 5.5 while you still can.
