I thought about a turnbuckle for a lot of people were using 'em in the youTube videos. But I decided to use what I had laying around before I went out & bought one. It has worked well in my roughly 30 miles of riding so far. My tension tube has only 1 setting, either attached or not. To me, you only want enough tension to get the job done, too tight & it's unnecessary friction. Too loose & it slips. Mine works great but will slip instantly once it gets wet, as I found out after a rain shower. I will go to a turnbuckle if need be but all is well with the simple pull down tube.
