I just bought an indoor trainer to use with my 3 speed raleigh. It has the sturmey archer
rear hub with the chain . I am wondering if there is a better way to mount this as the chain is pinched by this mounting. I tired peddling the bike and the chain keeps slipping...is that because of the lack of shift via pinched chain? I looked at the slack of the chain itself and it doesn't seem like it's too slack..there's no room to take one link out. Should a bore a hole on the trainer itself on that side to allow the chain movement?
