When I re-grease the linkage on the rear suspension there's one nut (connecting arm to frame nut) that I can't get a torque wrench on because there's not enough room. So I've been tightening it without the torque wrench wondering if it's too tight or not tight enough. Didn't want to spend the $ for one nut. Finally after several grease jobs and worrying about that nut I decided to buy the adaptor. The instructions were easy to follow. I was able to use the adaptor at a 90 degree angle to the torque wrench so I didn't have to recalculate the torque. The tool works awesome and I tested it to some other nuts that are accessible with the torque wrench alone. Spot on! I basically bought the tool for one nut but I'm glad I did. I am a wrench head and love to work on my bike and want it.done right. To me it's worth it for the peace of mind. Nice addition to the tool box!!
