Note: this question is about a QR chain tug, not a chain tug for a QR skewer. Just so we're clear.
My Google-fu must be weak after too much indulgence over the holidays, or maybe it just plain don't exist. I'm looking for a chain tug for horizontal rear fork ends to replace the threaded tug bolt that is currently built into the frame.
A. I like having the bolt/tug to help precisely tune the chain tension, rather than the "wheel walking" technique we all know about.
B. I'm considering running two sets of rubber this winter and anticipate doing a lot of swap-outs before my daily commute.
C. It adds precious seconds (lol) to my tire change routine and I can't find anything else I want to tweak on my current whip, so I'm micro-tuning now to feed the addiction.
Motivation (from one of my comments):
The objective of this theoretical QR chain tug would be to allow you to "set" the proper tension using the wingnut, but then be able to completely release the entire mechanism to be able to derail the chain and then remove the wheel. When you reassemble everything, just tighten the QR lever and you should be back to the correct tension, so then you tighten your axle bolts and you're off to the races...
Anyone know of / invented / hacked such a device?
Feel free to slag me and say, "just shut up and ride".
