500

[edit]

I've seen bikes in the past with Reynolds 500 tubing. Google suggests that it does exist although I don't know anything more. Anyone care to dig up some info? brob (talk) 13:19, 12 September 2008 (UTC)[reply]

[edit]

I have removed this link as it was added to refs section by a user that would appear to be connected with the content. It a review of a 953 frameset in Cycling weekly but was posted by User:Rourke953, so would appear to be WP:COI and/or an advert WP:Spam. I leave it for others to decide if its suitable as a reference for the 953 tub section.

653 tubing and Eddy Merckx

[edit]

From the article:

"653 - Following feedback from Eddy Merckx that a pure 753 frame was too harsh for certain stages of the Tour de France, Reynolds produced a 653 tubeset which combined 753 stays with 531 main tubes and forks. The 531 used was a thinner gauge than usual produced specifically for use in the 653 set. Eddy and other riders were very pleased with the result, which combined a light, ultra-stiff and efficient transmission with a more forgiving and comfy ride."

This paragraph is unsourced and seems to be factually incorrect.

653 tubing was introduced in the late 1980s, round about 1987-1988 and Eddy Merckx retired in 1978 so I doubt Merckx raced on 653 frames or even had any connections with the development of 653. In addition, 653 was made of 753 stays, 653 main tubes and 531 forks, not 753 stays with 531 main tubes and forks. 81.131.16.161 (talk) 21:12, 27 March 2009 (UTC)[reply]

My understanding is that the 653 tubeset (excluding the forks) was identical to the 753 tubeset prior to the heat treatment phase. The only difference between the two final tubesets was that the 3 main tubes of a 653 tubeset did not undergo the same heat treatment process as a 753 tubeset, hence their strength and stiffness was not quite as high as 753 tubes. The point to this was that the 653 frame could be subsequently built using high temperature braize techniques, and did not require the frame builder to be 753 approved (753 needed low temperature braize methods to avoid damaging the 753 heat treatment). As the rear triangle tubes of a 653 set were 753, one presumes some weakening of the rear triangle tubes probably occurred when using high temperature braizing methods. A final 653 frameset weighed exactly the same as a 753 frameset, and had the same tube thickesses (as the source tubeset was identical to 753) and was almost as strong. I have Reynolds brochures confirming this. — Preceding unsigned comment added by 194.106.220.85 (talk) 13:27, 23 January 2015 (UTC)[reply]

History

[edit]

A couple facts in the article on the history are conspicuously absent from the respected bicycle history book Bicycle:The History from it's little blurb on Reynolds. I've put {{fact}} tags up, but especially the 1897 date for d-butted tubes date sounds dubious. Herlihy mentions the introduction of 531 and d-butted tubes in the same sentence, no mention of d-butted before that. It's just a short blurb though, so I'll leave it up there for now.--Keithonearth (talk) 06:07, 11 September 2009 (UTC)[reply]

oops, I found a ref for the patent. I should have looked more, before complaining about no ref.--Keithonearth (talk) 07:38, 11 September 2009 (UTC)[reply]

531SL

[edit]

The article has the following:

"531SL - Special Lightweight tubeset - 531SL was a tube set sold in the 70s which has 531 main triangle drawn lighter than standard and 753 rear stays. This was replaced in 1981 within the Reynolds range by 653."

The source given is "Taken from an email reply written by 'Terry' at toptubes@reynoldstechnology.biz dated 6th October 2008". According to Wikipedia policies, this would seem to be original research. Wikipedia articles are based on published content from reputable sources. The above assertions also seem to contradict the following from a Reynolds brochure:

"Reynolds 531 Professional:
This set supersedes the REYNOLDS 531 SL set and has improved weight and performance charateristics."

531SL was actually replaced by 531 Professional (531P) 92.40.79.16 (talk) 00:30, 21 November 2009 (UTC)[reply]

K2 steel tubing

[edit]

Rather than edit the page unilaterally, I'd like to suggest adding K2 to the list of steel tubing types (perhaps between 501 and 520?). K2 is/was cro-mo tubing from Reynolds, designed exclusively for Raleigh, and was used in place of 501 (at a similar price-point to 501) between ~1993 and 1995. There are still some old K2 frames going around, but there is very little information available on the web about this type of tubing - nothing much more than the odd passing comment on cycling forums over the years, or a brief mention in the preface of some ancient Raleigh catalogues.

Hilariously, a recent blog post I wrote looks to be the most 'authoritative' discussion of K2 tubing on the web, but it doesn't exactly meet the standards set by wikipedia's rules on citations... https://retrosteelrider.wordpress.com/2015/03/18/reynolds-501-the-entry-level-workhorse-of-vintage-mountain-bike-frames/ — Preceding unsigned comment added by 77.54.90.209 (talk) 00:18, 19 March 2015 (UTC)[reply]

For transparency, I'm the user who suggested adding K2 above, now registered with a wiki account. I've added K2 to the article, along with the link mentioned above. I hope my addition has been both useful to the community with an interest in historical bicycle tubing, and correct within the rules of wikipedia.

I've also added Reynolds Optima, apparently the successor to K2/501, to the list of steel tubing. Andrewjhumphrey (talk) 10:16, 20 March 2015 (UTC)[reply]

731

[edit]

I have looked at several magazine adverts placed by Reynolds in the late 1980s, all showing the various transfers, there are none shown for 731 (no letters, normal diameters) but some show a 731os transfer, which accords with my memory of the time of 731 being sold as a tubeset for heavy riders. — Preceding unsigned comment added by 188.31.10.39 (talk) 02:38, 18 September 2015 (UTC) http://www.velocipedesalon.com/forum/f2/reynolds-731-a-19682.html — Preceding unsigned comment added by 188.31.10.39 (talk) 02:41, 18 September 2015 (UTC)[reply]
