Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque

Works Well, Tastes Good, Lasts a Long Time
Size: 3 Ounce (Pack of 1)
Needed to get a product with no fluoride and not made by one of the large mfgrs of toothpaste. I used to used HELLO, but they were bought out by Colgate. Not a fan. So, I thought I'd try this as I used to live near the area this is produced. It is a lesser sweet taste than the HELLO product lines, but very nice results after just a couple uses and the taste is fine. Works well, tastes good, affordable.

Keeps breath fresh for longer.
Size: 3 Ounce (Pack of 1)
Love this toothpaste. It’s like another brand that made the pm toothpaste that was good for morning breath. I wake up and still can somewhat taste the freshness. Maybe the peppermint is good/strong, but works well without the burning sensation.

Cleaner teeth
Size: 5.5 Ounce (Pack of 1)
I feel like my teeth get cleaned better with this product than usual mass market brands. Only downside is it doesn't have enough mint flavor to act as a breath freshener. But it's perfect if you can't tolerate a strong mint taste.
