Not on a Lurcher, but with another horizontal dropout bike I found that if my chain tension was too high the wheel would get tweaked to the NDS of the bike by moving the NDS axle back a touch. This reduced chain tension and is not controlled by a chain tug.Any one else running the lurcher with the single speed drop,out having issues with chain tension? My rear wheel has a 135x12mm hub and I tried using 2 different types of reducer axles and no matter how tight I try to tighten the nuts, seems like chain looses tension after a couple rides. I finally gave up and bought some chain tugs and installed on both drop outs and seems like the wheel,is still slipping., how is that even possible? The tugs should prevent the wheel from sliding forward right? Anyways, just curious if anyone has the same issue. Wondering if getting new drop outs might help
All I had to do to resolve the problem was to run the chain with a little more slack in it. That is better for the drivetrain and your bearings anyways.
