Was very easy to install, however after 6 months of very light use the dummy sprocket stripped and sheered the bolt and now it’s unusable halfway open. I can’t seem to find a replacement dummy sprocket bolt and no way to contact seller..Update: after some time the seller did follow through and send a sprocket. I think the dummy sprockets should have threading that can shear off. Maybe they can make a model where the dummy sprockets are heavy thru bolts with a greased pin
