I have used these shifter before and not had a problem. I bought this one for a CR80. As usual from Sunline the product was nicely finished and appears tough unitl you get to where it connects to the shaft. I dont know why but they machined a lot of material away from the shifter in this area. and the thickness and way the pinch bolt close are just weak. Also, the splines on the inside of the shifter mount were almost non existent. Between these two ailments even with red loctite the pinch bolt would back out and then the shifter would slip. I almost sent it back thinking that it had to be some kind of manufacture defect due to the lack of proper spline height. I ended up just reinstalling the stock shifter which works fine.
