As with all of my MateMod creations I only make things to improve my experience with my MateX bike. I use my bike everyday to get to and from work and my chain comes off at least 3 times a week if I ride over some rough terrain.
So i've made this frankenstein part from a pre-existing chain guide. I can report back that it works a treat! My chain has stayed on all week despite actually looking for holes and lumps to ride over.
The part that I use is expensive to buy in the first place, so I apologize for the price of the part. But if you are experiencing the same problem as I was it's well worth the money.
As always, thanks for the support.
