Blah - Chain Tug
I figure I'm probably just unlucky. I'm just running the one combination of chain length, gearing and track-end length to have problems...
Went by the LBS at work to pick up a Surly chain pull today. I've been having trouble with my axle moving back just enough when I put the last turn on that it makes the chain too tight. I should have the solution in my hands, that's what I'm thinking as I head back to work.
Waiting for third shift to arrive so I could get out of there (we're slow and vacation starts tomorrow night - you know I'm working hard ) I threw it on. Seems simple enough, but I notice that with the axle in the furthest hole, the thumbscrew is all the way undone, and it's still a little too tight!!!
No problem, I move to the closer hole, and thread the thumbscrew all the way in. Yup, all the way in. Just.... a little....
I'm sure that if the axle was starting just a couple of mm in either direction, there would be no problem. I'm going to switch over to the 14t side tomorrow, and it should be good. Adding another two links of chain actually leaves the 14t way too close to the back of the dropouts, so that's not a solution. A 1/8" halflink would probably work, or one of the Wipperman chains that are nothing but halflinks. Changing my front chainring could work too, but I want to hold off on that until I get a new set of cranks (leads on affordable, really stiff JSO taper all black 165s are appreciated ) I think even a mm or two longer or shorter screw or a slight difference in the spacing of the holes would work...
No real reason for this post, just needed to vent.... Should have just spent about the same amount for the NJS tugs on ebay and waited, but no, I needed to fix the problem tonight...
ach laddie, ye have the answer yerself, get the mks, sell the surly ad ye'll be set.

I suppose there are worse places he could show up uninvited... At least in your brain, you can assume he's imaginary...
And how am I going to open my beer bottles if I quit smoking without the surly? I won't have a lighter to use then...
Answer me that!
that's easy. carve an opener into the end of your peanutbutter wrench with a grinder.
Can't you just hacksaw 1/8" off that bolt in the tug? I'm not looking at mine and I don't remember the exact mechanism.
If so, it will take you under a minute to solve your problem
I don't have a peanutbutter wrench, so that's not an option. I'm pretty sure I could improvise with whatever tools were nearby, though...
There's a little c-ring that clamps on the end of the bolt, I think to keep it from threading too far... I might be able to hacksaw/dremel it, but I would worry about burrs stripping the threads on the kinda square thingy that's used to create the tension...
If you want to go supa-dupa cheap, let me know your address and I'll send you one of my BMX star-with-two-bolt types.
