Grooved sprockets have cut-outs at the bottom of the tooth to allow the escape of mud that would otherwise be trapped between the sprocket and the chain. This prevents tension from being placed on the chain and the resulting accelerated wear
Using advanced computer engineering alongside CNC machining, Renthal consistently achieves perfect concentricity, fitment, load dispersion and uncompromising strength whilst ensuring maximum power delivery.
Features:
- CNC Machined - To account for the extremely high tolerances required for engine components, Renthal utilises in-house CNC facilities to accurately machine each individual sprocket to the tightest tolerance possible.
- Core Refined - Core-refined 655M13 Nickel-Chrome-Molybdenum alloy steel provides the ultimate combination of strength and hardness.
- Mud Grooves - Self-cleaning mud grooves between every tooth on both sides to help prevent dirt build-up.
- Case Hardened - The case hardening process ensures that the sprocket has the longest service life possible. Each sprocket undergoes heat treatment to harden the surface.

My number one choice for dry mouth. Really works and worth it.
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
These do work for very dry mouth. My dentist recommended these because l am on a medication that causes dry mouth. I had no idea it could be this uncomfortable ! It gets to the point I cannot spit after brushing my teeth, can’t make the kiss sound to call my dog, even my voice has been affected. It’s the worst.
Sometimes though one tab isn’t enough. I use 3 at once at night. One on each side of mouth between my teeth and cheek, sticking them to my cheek and one on the roof of my mouth. If you have trouble with them sticking to your cheek, definitely try the roof of your mouth.
The taste is extremely mild. It’s hard to describe but the flavor but it’s not unpleasant in any way. I rather like it. You get more of a very slight gel consistency when they melt which is what you want.
They last in my mouth for hours. I haven’t timed it but it’s half a night’s sleep some nights if I’m asleep. During the day they don’t last as long but still a long time.
I’ve been trying different products for dry mouth and I do like to mix it up but this is my go to for serious dry symptoms and nighttime. I really like the sticking feature they have. Will continue to buy.

Good for dry mouth
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
These are one of the few things that help with the pain of my Sjogren's dry mouth. They stick securely and safely. They have a mild minty taste with no menthol. They dissolve without grittiness. I highly recommend them.

Works great, not always comfy but I do recommend
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1), Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
I am a senior who raised a family, had a career and held down a household. Apparently, however, I’m not competent enough to use a mint 🤷♀️🤣 The first one I tried to “install” ended up in a mess in my lap. After putting on clean pjs I decided to try again, my hubby glanced over and asked why I was trying to stick my fist in my mouth and when I started laughing the mint shot halfway across the room. I am nothing if not persistent, so decided to practice with a couple. I put one in my mouth and attempted to position it with my tongue as the instructions suggest, within 2 seconds it firmly attached to the roof of my mouth. I finally managed to get two stuck onto my gums (using my finger) and they worked perfectly! Of course when I woke up there was a small tan drool spot on my clean pillowcase. I assume it’s from the side of the mint that attaches, which is a tannish brown color. Now I use one per night, they can be really hard to use sometimes but are extremely effective. They have a slightly sweet, very pleasant taste. I use multiple dry mouth products as I have COPD & use oxygen 24/7. I am prescribed 2 inhalers and a nebulizer, all of which cause awful dry mouth - to the point of feeling like my lips are stuck to my teeth some mornings. These are the ONLY things that have made that seem like less of an issue. I sleep an average of 5 hours per night and the mint has already dissolved by then, but my mouth still feels moisturized. I don’t notice any weird taste when I drink a glass of water upon waking, just a pleasant non-taste. I do recommend, just be patient! Photo is front and back next to a Tylenol caplet

Great product
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
These are so helpful for me. My dentist in Chicago recommended them about 7 years ago because I have severe dry mouth. Typically I'll use 3 to get me through the night. I'll put another in my mouth after taking a sip of water if needed. These have (I believe) prevented me from having any cavities since I started using Xylimelts. The active ingredient prevents bacteria from attacking my teeth. My dentist has been pretty impressed with the outcome. There are multiple flavors, I like the mild mint and the unflavored ones. They are a little expensive, but well worth the price. Especially with no cavities and being more comfortable at night. I love the fact that they stay where you place them too.
