Title: Chain's a bit slack
Post by: Si on 28 March, 2008, 09:45:59 am
Sorry, had to be first :P  No, there is indeed a question related to slackness.

Thoughts on tugs for wheels that use QRs on frames with forward facing slanty ends?

Does anyone do them anymore?
Do you think that they cause problems if the tug is holding the QR spindle rather than the axle?

I've bodged one up but...it's not the nicest thing in Christendom.  My initial thought was to put the tug inside the end so that it did go around the axle rather than skewer but this changed the chain line (could rest the back I guess).  So at the mo I've a 'normal' tug hanging onto the skewer.

Fixedwheelnut uses them - Cyclo made them, I think.

 Yes I use the old Cyclo chaintugs, usually pick them up at Jumbles for a few quid a pair.
 E-bay ones go for ridiculous money.

They look good - does the thread of the bolt match an adjuster hole at the back of a "standard"  forward facing dropout?

  The threaded bolt screws in to nut fitted in the tug and pushes against the back of the drop out, I do tend to locate the thread into the hole to centre it. The nut you can see is then screwed up against the tug as a locknut.

Ah, it's occured to me that those cyclo ones won't be any better than my bodged ones for my bikes as the holes in the two arms are the same size: I've got a standard QR so the outer hole needs to be smaller.  But been doing a few short sharp hills today and I think the bodge is holding together OK.
