thread_title: To do

message: Does the Tufo 'tubular' cited as an example of a tubular without an inner tube truly constitute a tubular tire?  If a tubular tire is defined as 'any tire that is designed to work on a tubular rim' It would not work.  If tubular tire is defined as 'any tire that is stitched closed to form a torus' then this tire almost works.  The reference refers to it as a 'tubeless road' and 'tubular clincher' tire.  I am interested by the tire but inclined not to cite it as a reference that a tubular tire doesn't contain an inner tube.  For the moment the article claims that a tubular 'almost always has an inner tube'.  This seems like a fair compromise until we resolve this.   Ender8282 (talk) 23:44, 3 February 2009 (UTC)
replies: text: Do not confuse Tufo's 'tubular clincher' tires, designed for clincher rims, with their pure 'tubular' tires, designed for tubular rims. Perhaps the current definition is not worded in the best way possible. It seems that the salient aspect of 'tubular' is that the tire cross section is in the form of a tube, and then the Tufo tubulars definitely fit. This VeloNews article and this Road Cycling article have no trouble calling Tufos tubulars. The slangy 'sew-ups' would be no weirder than 'clipless pedals' or 'threadless stems'. -AndrewDressel (talk) 14:26, 4 February 2009 (UTC)
replies: text:  The Road Cycling article still talks about a tubular-clincher.  The VeloNews article is most definately NOT talking about a tubular-clincher hybrid.  This most certainly proves the point that 'not all tubulars have a seperate innertube'.  I might prefer that the VeloNews article were used instead of the current bike-eu article only because it is refering to what I understand a tubular tire to be.  However the Bike-eu and the Road Cycling articles provide a picture that explins what is going on far better than VeloNews does. Ender8282 (talk) 16:46, 4 February 2009 (UTC)
thread_title:  Tufo Tubular 

message: Caption to :Image:Bamboobike.jpg claims that the rims are wooden... I doubt this and there is no mention of it in the image summary. They look like rusted steel to me. Have messaged the image uploaded but consider this a request for any other input. bad·monkey talk to the {:()  ::  05:55, 3 April 2007 (UTC)
replies: text: Yes, the wooden bit is actualy the tyre. If there were no metal rim as well, then how would the metal spokes be fixed to the rim securely enough perform well?Gregorydavid 13:10, 3 April 2007 (UTC)
replies: text: In fact it is highly likely that the rims are made from wood.  Wood was the most popular material for rims around that time and metal rims only became popular (on safeties) with the rise of rim brakes (which this bicycle does not have).  The tires are certainly not wood, they are pneumatic rubber types, the valves are visible coming out of the rims. Will.law 17:13, 3 April 2007 (UTC)
replies: text: Wood definitely have been used for making rims. LDHan 21:42, 3 April 2007 (UTC)

text: The fact that wood has been used for rims is not in question; merely what this picture is of. If you look around where the rim meets the tyre (which is most certainly not wood!), you can see shine and reflections which give it the appearance of metal to me. bad·monkey talk to the {:()  ::  03:39, 4 April 2007 (UTC)

thread_title:  Wooden rims 

message: At time of writing, the article says:
: The number of spoke holes on the rim normally matches the number of spoke holes in the hub. Some unusual rim designs have no holes for spokes, for example Campagnolo road rims and the Velocity Zvino MTB rims.
Huh - Campagnolo rims (presumably, the rims used on Campy's own wheels) don't have spoke holes? Both my sets do! Which wheels don't use holes for spokes? If it is just a few designs, we should probably say "...for example some Campagnolo road rims...". —The preceding unsigned comment was added by WikianJim (talk • contribs) 20:12, 15 May 2007 (UTC)
replies: text: Anyone? WikianJim 19:22, 28 May 2007 (UTC)
replies: text: Here's some info on the Zvino []  & [].  I think saying that they don't have holes is misleading though.  The rim still has holes, just in a separate section of the rim.  AFAIK, campagnolo rims all have spoke/nipple holes. Just not in the 2nd layer of aluminum so you don't have to use rim tape. Will.law 14:59, 30 May 2007 (UTC)
replies: text: Right, I get this now! On a double wall rim they have holes for the nipples to poke through, but not on the bit that touches the innertube/tubular. WikianJim 16:03, 1 June 2007 (UTC)
thread_title:  Rims with no holes for spokes? 

message: Sorry again about the revert, but the recent change had a lot of points to discuss
#It lost two alternate name "sew-up" and "single" that I think are very useful in an encyclopedia article.
#It added "hooks" to the definition of the alternate tire type commonly, and apparently erroniously, refered as clincher. See the discussion section just above this one to see that "hooks" do not define clincher.
#It tosses out a reference without replacing it as discussed above.

thread_title:  Lead section and definition 

message: Can someone tell me if (and why) the mention of UST here?  It seems irrelevant because UST rims are still made around the same 26" standard as non-UST rims, and this section of the article is talking about the size of the rim, right? HuntClubJoe (talk) 21:21, 12 June 2010 (UTC)
replies: text: I believe a discussion of 26 x 1.25, 26 x 1½, etc. should be included because for the average reader the 'wheel' includes the tyres.  People should understand that the size 26in is only nominal, and the sizes of the various non-standard tires should be explained in terms of the UST/ISO/ETRTO standard. Hedley 06:03, 7 May 2012 (UTC)

thread_title:  giving it the greatest strength to weight ratio of any man-made structure? 

message: I don't understand how to measure the the diameter of the tire or rim, from the way it is described in the article. Both says smth with "where the tire sits", but exactly where is that? The tire and rim has an overlap if measured from the center of the circle and out. It needs a more precise/explicit explanation, or perhaps a diagram.

thread_title:  Nonsensical statement ? 

message: This article disagrees with another in Wikipedia. From this article:
:The average 29-inch mountain bike tire has an outside diameter of about 28.5" (724 mm).
From 29er (bicycle)
:... the average 29" mountain bike tire is (in ISO notation) 59-622 - corresponding to an outside diameter of about 29.15 inches (740 mm).
Neither has a reference.

message: I'm convinced prior art for nipples in the hub (and not in the rim) goes to Ringlé, 1991, but cannot find any reference for it online.
They've been later bought by Sun, who've been the first to actually integrate the nipples (1994? 1995?) and not Industry Nine (2018) who are credited currently.  — Preceding unsigned comment added by 2A01:598:A006:6453:4C6E:AFFF:FE0C:8218 (talk) 01:20, 7 January 2020 (UTC)

thread_title:  Other types 

message: @McKnight, I undid the first of your two recent edits, because I highly doubt its content. Whatever the mechanic quoted in the reference witnessed, the explanation must be wrong. Rim diameter does not decrease with tire pressure, at least not noticeably. If rim diameter changed, rim circumference would also need to change. This in turn would require that the rim material would noticeably compress, which it does not. Solid materials, in particular metals, usually do not noticeably compress with pressure. Aluminium has a Young's_modulus of 70GPa. Let's try a naive approach and assume that the pressure is along the length of the rim. (I know it does not, the tire pressure is radial, but my gut feeling is that the end result remains about the same.) To get the length contraction, we divide the tire pressure (about 10bar=1MPa), by Young's Modulus and arrive at 1MPa/70GPa = 1/70000. For every meter of rim circumference, the tire compresses it by 14µm (0.014mm). Not noticeable, I'd say. --RainerBlome (talk) 20:46, 3 December 2021 (UTC)
