Hey JzG, you managed to make lawyer tab longer than dropout (bicycle part). :-> --Christopherlin 23:38, 14 March 2006 (UTC)[reply]

Well is it my fault that lawyer tabs are controversial? ;-) No objection to a merge, but the redirect should remain of course. Just zis Guy you know? 00:01, 15 March 2006 (UTC)[reply]

Suggested Merges

Anyone got anything against them? If not, i'll probably do them this afternoon. --Lordandmaker 10:30, 24 April 2006 (UTC)[reply]

Suggested name change

This article should probably be titled forkends, since it talks about not only dropouts, but track forkends and front forkends. Dropouts are just one type of forkend. Unfortunately, there is no article on forkends, only dropouts. Jaywalk3r (talk) 01:59, 28 September 2010 (UTC)[reply]

Finally done. -AndrewDressel (talk) 13:48, 19 July 2012 (UTC)[reply]

The same guy?

This page links to John Forrester, an 84 year-old British MP, calling him an industry expert. His page makes no mention of cycling - a case of same name, different person?

Yes. Guy (Help!) 16:20, 22 November 2006 (UTC)[reply]

Not quite the same name. The cycling John is spelled Forester. Jamarks 17:29, 1 March 2007 (UTC) jamarks[reply]

Still a stub?

Seems complete now. Any objection to removing the tag? -AndrewDressel 14:42, 23 December 2006 (UTC)[reply]

I'm going to change it to a "Start", as it is certainly no longer a stub. In fact, it's probably B-Class. So I've changed it again. - Ice Ardor 06:33, 7 June 2007 (UTC)[reply]

Better picture

What about a picture of a front fork with lawyer lips. In my opinion that would be a much more clear photos. —The preceding unsigned comment was added by Wfisher (Talk) 00:38, 18 January 2007 (UTC).[reply]

Chain tensioners

The expression chain tensioner seems two be used for to different devices:

1. a device that dynamically takes up slack in the return section of a chain. It cannot be used in fixed-gear application. A rear derailleur is an example of this kind of chain tensioner. The Surly Singleator is another. Sheldon Brown calls these 'pulley-type chain tensioners'. They can be adjustable or spring loaded.
2. a device that statically sets chain tension at the rear dropout before the axle nuts are tightened. It can and often is used in fixed-gear applications. The Surly Tuggnut Tensioner is an example of this type.

Are there separate names for these two different devices?

Track fork ends vs. dropouts

The article classifies track fork ends, i.e., slot openings face rear, as dropouts, which is incorrect. Dropouts allow the wheel to be removed without derailing the chain first. Track fork ends do not allow this. —Preceding unsigned comment added by Jaywalk3r (talkcontribs) 00:51, 28 September 2010 (UTC)[reply]

That appears to have been corrected. -AndrewDressel (talk) 15:54, 21 January 2011 (UTC)[reply]
Actually it does not seem to be corrected; or else I am confused (a real possability...): it would seem that there is no such thing as "horizontal dropouts"? A drop-out is a vertical or semi-horizontal fork end, but a horizontal fork end is not a drop-out, as there is no "dropping out" possible? If so, then shouldn't all references to "horizontal dropouts"(etc) be changed to "horizontal fork ends"? (i.e. see picture caption, "Horizontal rearward-facing track fork end (not a dropout)") Grye (talk) 04:28, 12 May 2014 (UTC)[reply]

Rear derailleur hanger misalignment

An anonymous user has twice replaced

If it is out of alignment, the rear derailleur will not move far enough, with respect to the rear sprockets, with each click.

with

If it is out of alignment, the rear derailleur may not keep the chain in line with the rear sprockets, with each click of the shifter.

and I have reverted it twice. Here is why:

  1. I believe the original is technically correct. With indexed shifting, a bent hanger prevents the derailleur from moving the correct amount because it is moving along the hypotenuse of a right triangle whose base is parallel with the rear axle.
  2. The new text is vague and seems to suggest that it is the orientation of the rear derailleur cage and not its position that causes the problem. While misalignment of the rear cage can be an issue, it can also be caused by a bent rear derailleur and it does not vary from click to click of an indexed shifter.

Sheldon Brown has this to say on the topic at [1]:

If the rear indexing works properly when using the large chainwheel but not on the small chainwheel, or vice-versa, this is often a sign that the rear derailer hanger is bent.

and

Note, wide-range Campagnolo derailers have cages that are not intended to be vertical; the lower pulley is farther outboard than the jockey pulley.

Thus, the symptom of a bent hanger is that indexed shifting is not consistent over all the sprockets, and the rear derailleur does not have to be aligned with the rear sprockets for correct shifting. I hope that by discussing the issue here, we can avoid a minor editing skirmish. -AndrewDressel (talk) 15:54, 21 January 2011 (UTC)[reply]
