I've been watching the DRB belts closely recently.
This path has the belt under a bit of stress. that 90 degree turn on the bearing, is a bit undesirable.
I thought this item wouldn't last much longer. Hanging by a thread kind has a literal meaning.
So... Hmmm. DRB-516B1 + DRB-189B1 3.5mm FCD 1.8 Low Friction Rear Belt and 3.5mm Low Friction Front Belt.
I don't know what makes them think wider belt = low friction... by my calculation, more contact area = more friction. Perhaps the soft brown threads will make the chassis so much faster... haha.
Anyway. turning the drive-train by hand feels a slight improvement in smoothness and I hope durability. Probably something that should have been stock.
Yokomo... are you listening. People don't want to upgrade every freaking component.
If you make a Competition Level Kit. include everything.
