What are APEX, EDGE, and CORE?

Our three spool bearing classes:CORE — solid standard tuning, good value for money, noticeably better than the factory bearingsEDGE — higher-quality bearings for noticeably longer casts and smoother castingAPEX — the best we can recommend for your reel, uncompromisingly focused on maximum performanceThe reel page tells you directly which class is right for your reel — we make recommendations for each series.

Q: Does tuning damage my reel? Will I lose the manufacturer’s warranty?

Tuning is reversible — all parts can be swapped back. So if you ever want to go to Shimano service, you reinstall the original parts and everything is back to factory condition.Regarding the warranty: Bearing replacement is usually unproblematic (spool bearings are wear parts). Replacing handles or other components could theoretically lead to warranty discussions — but in practice, most warranty cases involve damage unrelated to the tuning.

HOW IT WORKS — 3 STEPS

Step 1 — Find your reel

Search for your reel by manufacturer, series, or model code. Whether it’s a Shimano Curado, Daiwa Tatula, Abu Garcia Revo, or Quantum Smoke—if it’s listed in the shop, we’ll find it.

Step 2 — See compatible parts

Click on your reel. We’ll show you all the tuning parts that genuinely fit your model—no list of 500 bearings where you have to figure out which ones actually work.

Step 3 — Tune it

Order directly from the shop. We pack every order ourselves—you get what you need, not what some algorithm suggests to you.

FAQ — Frequently Asked Questions

Find your reel in the finder above and click it. On the reel page, you’ll see all the compatible parts—spool bearing sets, knobs, handles, star drags, and whatever is relevant for your model. No guesswork, no need to research it yourself.

Standard tools are sufficient for most tuning: screwdrivers, tweezers, and possibly an Allen key. On some Shimano baitcasters (Curado, Bantam, SLX, and co.), the spool is secured with a small pin—you need to remove it to replace the bearings. That’s what the Pin-Remover, a simple specialized tool, is for. On the reel page, you can see whether you need one—if so, it’s linked directly.

Yes—with one caveat. The DC brake itself is electronic and can’t be tuned; there’s nothing to adjust. But bearing tuning works just as well on DC reels as on any other reel—you get longer casts and smoother spool performance. Swapping knobs and handles is also no problem.

On each reel page, you’ll find the recommended knob sizes directly below the image. We researched this by hand for every series. So, for example, if you have an SLX and 25–27 mm is recommended, you’ll immediately know which knobs to add to your cart.

Sure. With spinning reels, it’s mainly about different knobs, longer handles, line rollers, and reel stands. Just search for your Stella, Stradic, Tatula, etc. in the finder—we’ll show you what fits. Spool bearing sets aren’t available for spinning reels; they’re a baitcaster thing.

Just drop us a quick message—we’re constantly updating the database. We can often add the reel within a day or two once the specs have been properly researched. It’s usually faster than you think.

What does tuning actually do?

A tuned reel spins more freely, lets the lure fly farther, and gives you a more precise feel at the drag lever. Especially when fishing for pike and catfish, where the cast determines your chance of a bite, you’ll notice the difference immediately. With the right bearings, knobs, and handles, you get the most out of your reel without over-modifying it. And if you eventually want something different after all, everything can be restored to its original state.
