Tubing

But, but, but.. people on the internet have said 531 is some of the best tubing ever!
...so comfortable, lightweight, strong, beautiful, elegant, British, classic, coveted, unbettered, wonderful, springy, avec souplesse, tight, forgiving, resilient, responsive...
How can you argue!

Certainly looks like it's given this guy a boner:

531 is old hat compared to modern steels. it was replaced by 525 which is the cheapest steel reynolds make (i don't include 520 which is just rebadged tubes not made in the u.k.)
saying 853 is more fragile is complete and utter bollocks. if you look at the specs for 525 which replaced 531:
UTS - 48 - 58 Tsi

              100 - 130 Ksi
              700 - 900 MPa

compared to 853:
Reynolds 853 - Heat Treated

              UTS - 81 - 91 Tsi
              180 - 210 Ksi
              1250-1450 MPa

the only thing it could possibly lose out to is perhaps dent resistance due to the wall thickness (down to .4)

HA! you allowed unbettered to slip through your grammar-filter Platini..
Keep ignoreing littel mistaikes please.

Nothing wrong with unbettered.

I'm using 700531 SLX steeluminium, and Sheldon wasn't lying when he said it was greater than the sum of its parts. The vertical compliance is fucking mind-bending.

But is it laterally stiff enough?

columbus 'boner' will almost certainly have the required lateral stiffness.

it would if it was double butted

mercian and bob jackson OTP still run 531. and because what prav said above, rpm is wrong (as usual)!

how can I be "wrong" when all I said was there are better tubesets than 531?

I never said you couldn't still get it, fuckbrain

you come out with so much bullshit on this forum, ever tried thinking, or reading abit before posting?

My post about 531 was taking the piss a bit dogs..
In a fight between a builder and a scientist my money is on the builder.

they don't, it's 631.

dale is wrong as ever.

first bit was in response to mrsmith. 2nd bit to u ;)

"531 is awesome tubing" t-shirt is on the way, with token pair of risers ;)

standard tubing for BJ is 631(525stays) any 531 they have is old stock. mercian have some old stock tubesets too. when i replace the bent top and down tubes on my mercian i'll get them to fit the lightest/strongest tubes that are available to fit the lugs. they can save the heavy hard to get hold of stovepipe for people like dale :-)

531 is nothing special. Maybe in 1970 it was something special but now.. meh.

RPM is right. Dogs is wrong. I am off to the pub now.

Mercian frames have been constructed using Reynolds double butted tubing since 1946, giving us vast knowledge and experience in the properties and qualities of the tubesets.
Reynolds closed production of 531 and 653 tubing over recent years. 531 has been replaced by 631 butted tubing, the stronger equivalent of it's predecessor. Our friends at Reynolds tell us that 631 tubing with 525/725 stays are upgrades on 531. These are now the standard tubing options used in our frame range.
653 has been replaced with 725 chrome-moly butted tube sets.
For frames in 853 tubing and the even lighter 853 Pro Team tubing - see individual frame models.

                            For further tubing information                                  please check out Reynolds website [www.reynolds-cycle.com](http://www.reynolds-cycle.com/)                                  
                           At                                  the time of writing this website we are in the                                  fortunate position of having stocks of 531                                  and a small stock of 653 tubing still available                                  (while stocks last). Please specify your choice.

531 tubing is the same price as 631 tubing.

                            653 tubing can be added                                  to your frame order at a cost of £100.00 + VAT.

Next week on Mythbusters, we take a look at Velocity Deep-V rims, hipster or dumpster...

This thread's gone down the tubes...

LOL - Hipster or Dumpster!

they don't, it's 631.

dale is right as ever.
explains why i don't like either.

It's all about 531c.

Oh hang on, it isn't.

531st the touring tubing is really nice

531db is real low-end stuff.
