message: "with 20 TPI (a thread pitch unique to bike pedals)." - MAlvis (22:46, 15 November 2006)
:While Sheldon Brown confirms the 20 TPI, my Sears/Craftsman 50 Piece Tap and Die Set (hardly anything fancy) contains dies of size 1/2 x 20, 7/16 x 20, and everyone's favorite 1/4 x 20. Also, my Park Tool pedal taps are labeled only 9/16 x 20 (LH and RH), and the pitch matches exactly the right hand 1/2 x 20 tap that comes in the Sears set. I'm skeptical of the claim that 20 TPI is "a thread pitch unique to bike pedals." Does anyone have a source or additional information? -AndrewDressel 21:06, 16 November 2006 (UTC)
replies: text: Okay, so while 20 TPI is the correct pitch, there doesn't appear to be any evidence that it is unique to bicycle pedals. I'll remove that statement. -AndrewDressel 14:41, 22 November 2006 (UTC)

replies: text: I'm not familiar with the term "chainset", could someone clarify where it's used? I assume it's a regional term.  --Keithonearth (talk) 19:47, 5 July 2009 (UTC)
replies: text: It is not in the OED, but then neither is "crankset". -AndrewDressel (talk) 14:35, 5 September 2011 (UTC)

I can't find a source to confirm either one of these claims. Can anyone else? -AndrewDressel (talk) 14:13, 28 March 2008 (UTC)

message: It might be worth mentioning that altering the length of the crank alters the effective gearing, inches development doesn't change, but leverage does in any particular gear. This is discussed in Sheldon Brown's gain ratio page.  —Preceding unsigned comment added by 203.59.177.34 (talk) 02:17, 6 June 2008 (UTC)

message: Should this be spun off to its own entry?  Currently Chain Ring redirects somewhere quite unhelpful. 220.233.42.204 (talk) 11:35, 5 July 2009 (UTC)
replies: text: I just found chain ring (spelt as two words) in the OED: n. (b) Cycling a sprocket on a bicycle which transfers power from the cranks to the (rear) wheel by means of a chain, so I've created a disambiguation page to which both spellings redirect. -AndrewDressel (talk) 14:00, 5 September 2011 (UTC)

message: It worth mentioning the different sizes of axles diameters and the standard (24 mm shimano etc.) same size axle means that one can change BB from the original and it will stay compatible. --Nathandor (talk) 08:26, 6 November 2010 (UTC)

message: Your page seems to miss out this basic data.   With the front shifter's cable pull it allows knowledge of the front derailleur's shift ratio, (actuation ratio).   I notice that some spacings are about 10mm while others are closer to 6mm, but the data seems only to be available by measurement.   Nonetheless a few such dimensions would be useful.   Are double and triple spacings the same? Ronpedia (talk) 13:35, 5 September 2011 (UTC)
replies: text: I can find no mention of chainring spacing in any of my sources. Not even Berto's "updated and expanded" The Dancing Chain mentions it despite extensive coverage of differences in the number of teeth supported between adjacent chainrings. -AndrewDressel (talk) 14:06, 5 September 2011 (UTC)

message: Expanding chainrings seem to be repeatedly invented and fail.
They are a more complex form of Expanding pulleys, which seem just as dubious with pages of patents and little actual use.
I suggest they be added to the article, but this requires some hairy net spelunking for sources. Musaran (talk) 20:49, 29 October 2016 (UTC)

message: There seem to be some thoughts lowering the crank size for children's bikes can lead to the center of gravity of the bicycle being lowered which may be beneficial for children.  I dont want to do a bad edit a B-Class article on this. Thankyou.  Djm-leighpark (talk) 08:12, 26 June 2018 (UTC)
replies: text: I don't know who is thinking this, but I wonder how they think a lower center of mass may be beneficial for children. -AndrewDressel (talk) 12:08, 27 June 2018 (UTC)
