Mt Bikers - Tensioner Q
I have a question about fixed tensioners, such as the Rennen Rollenlager, Sette Chain Guide II, Gusset Bachelor, etc...
All of these fixed tensioners have two lock points. One being the axle, the other being the rear derailleur hanger. I'm trying to understand if something is normal here, seeing as though I own the Sette Chain Guide II.
If you have the chain tensioner on and adjusted properly, then flip the bike upside down so the bottom of the chain was on top, and then push down on the chain a good bit, is it normal for the tensioner to move, therefore slacking up on tension?
Reason I ask is my chain tensioner has a lot of wear marks where the bolt downs are. I wasn't sure if this would be a reason to cause it to be "slippery" for the bolt to grab onto to lock it down properly.
I started to think maybe this was normal seeing as though Sheldon's guide emphasized on how tensioners shouldn't be used with coaster brakes due to the amount of lower chain tension backpedaling causes, since tensioners aren't made to withstand that force.
Just trying to think out loud and get some ideas on whether or not this is normal. I did it totally on accident when I was testing the tension on the chain so, like I said, just wanted to ask. Thanks guys!
