Re: pic: Drivetrain WCD
The two idlers on the gearbox. Are they on bearings? What size bolt are they?
All the tension on your chain will cause a force on your idlers upward, wanting to bend the bolts.
Also, if your idlers are not on bearings, there will be a lot of friction between the chain and those bushings, due to the same tension from the chain.
If it was me, I would use the two chain loops.
