Review: Perfect reel upgrade - excellent grip and quality - This GOMEXUS power knob is outstanding! Perfect fit for my Shimano Stradic reel and the installation was incredibly easy. The knob provides excellent grip even with wet hands, which is crucial when fishing. The machined aluminum construction feels premium and durable. It's much more comfortable to use than the stock knob and gives me better control and leverage when reeling in. The knob spins smoothly and looks great on my reel. This is a must-have upgrade for any serious angler. Highly recommend!
Review: Fits Shimano Spheros as well! - I've kinda struggled to reel in the bigger trouts and reds on my Shimano Spheros 4000 and holy cow this knob made a difference! The stock knob is flat and thin, and with my big hands I could basically just pinch it between my thumb and index finger which led to a bit of a problem when I had 20+ inch fish on the line. This thing took my reel to a whole new level! It's a very easy install. On my Spheros, all I did was unscrew the two screws on the stock knob's nameplate, then unscrew the main screw to the shaft. Then I just slid the two bearings on either side of the Gomexus knob and used 3 of the thinner spacing washers. Some locktite is definitely required for the shaft screw, as you cannot torque it down because it will tighten down onto the bearings and prevent the knob from spinning free. But man is it an improvement over the bushings on the previous handle. I can now get a whole hand grip on this thing and crank those big fish in. As far as color and quality, it's solid. The gold.color is a lot more of a deep yellow gold than the gold on the Spheros reel. I might have gotten just a black model if I knew the difference, but I don't really care how my equipment looks as long as it's working. At a glance, it looks stock, but up close it's definitely a different color. The build is pretty sturdy. I went from a plastic handle to a milled aluminum piece, so it's already a drastic upgrade. And the quality is surprisingly good at this price point. Everything is smooth, the paint and finish is sharp, and it's really just more than I expected. Overall, it's a heck of a deal for under 20 bucks (at the time of writing). The 38mm model DOES fit the Shimano spheros sw 4000 even though it's not listed. I'll be upgrading all of my reels with this handle/knob.

## Questions & Answers

**Q: Will this fit Sahara XG 4000**
A: If it fits the SHC3000HGFI I cannot see why it will not fit the Sahara XG 4000.

**Q: I need 3 for penn clash , 2500, 3000, and 4000**
A: We have 35mm in black gold, black silver, black red, silver gold and silver smoke black fit your reel perfectly. Please refer to: https://www.amazon.com/dp/B078XSHY4D

**Q: What size shaft  knob do i need for a shimano stradic st4000xgfk?**
A: I am not positive - I have been putting all my gomexus knobs on baitcasting handles which require Shimano A fitting.  It appears that Gomexus will tell you that a stradic 4000 spinning reel handle will take a Shimano A knob...   Spinning reels of 5000 or larger require a Shimano B knob.  Hope that helps.

**Q: What size should I get for the shimano sedona 5000?**
A: you can choose 38mm/41mm for sedona 5000
