KMC - E-Bike (BOSCH GEN 4) ChainringsKMC E BIKE (BOSCH GEN 4) CHAINRINGS A drive is efficient when chain and chainring work together perfectly. The most important factor here is an optimum form and force fit, which is created by a minimum of play between the drive components. Precision is the central KMC issue in the development of advanced drive components. For the Bosch Gen4 chainrings, for example, they designed a completely new tooth profile: It prevents the chain from falling off

I was using the Paula’s brand but stopped ordering because the price kept going up. This came up in my search and it’s almost the same except it has a stronger concentration & has a few more added benefits. It’s also about half the price. This product works great & I’ve been using TruSkin Vit. C moisturizer for years now so I knew their other products work for me and are good quality.

It works for my Very sensitive skin

This is the most gentle liquid exfoliant I've ever used. I have very sensitive skin and 3xs a week doesn't bother my skin at all! I Highly recommend it. DS

Bye bye ingrowns and dark spots

I love this exfoliant, I've bought it 3 times already. I use it on all my hyperpigmentation on my back, underarms, and face. It really helps with my ingrown hairs and reduces the appearance of dark spots. Super effective, I love it!
