[QUOTE=Salamandrine;19222422IIRC 531P wasn't as nutso light as 531SL. Frames were a few (8?) ounces lighter than regular 531.[/QUOTE]
On your latter comment I'd rethink what you written - eight ounces is one half of one pound; in addition the 531 Professional tubeset, to give it it's correct name, was a replacement of the 531 SL set (and apologies; your former comment is nonsense).
The Pro' tubeset would be nominally lighter at 1900 gms, than the 531 C tubeset at 2050 gms. My own SBDU frames is built from the Pro' tubeset, and one of my Roberts is built from the earlier (531 SL) set.
Can't think why a decent builder would build a touring frame in Pro' !

Because it is not a touring frame but a randonneuring bike. Going long distances fairly fast to keep within a certain time constraint.

I don't need a lesson on the difference, been riding handmade bicycles for four decades. My comment is still relevant, 531 Pro is still an unusual choice for a frame not designed for either TTs or racing.

Then I'm kind of surprised that Follis didn't consult you before speccing this tubeset.

Nicebike, and fairly rare stateside.
I'd commute on it, but wouldn't lock it up in a rack. 531P is fairly thin-walled tubing and will be more prone to dents and dings from other bikes.
My current commuter has Tange 2 tubing, which is slightly thicker than standard 531, and it looks like it was attacked by an elf with a ball-peen hammer after two years of rack use.

Beautiful bike, it's nice to have something light and fast when you're that much every day. It doesn't look like there is much room for large tires, but if you have smooth streets and roads you won't need them. I used to commute on tubular tires. I would replace the ESGE rear rack with something stiffer like a Blackburn.

I've commuted more than a few times on this. It is built with 531C. The tires are Veloflex sew-ups on Mavic GP4 rims.
I can tell you the weight of the extra ink for the letter C on the decal has absolutely no effect on the frame's performance. It does just fine. I would not expect a P to be substantially heavier. Mind you, I weigh only 160lbs and carry only a substantial lunch and smarffone in a handlebar bag.

I believe those Mavic hubs used aluminum axles, and the 7-speed rear leaves a rather long unsupported length. Mine did fine for years and a 3-week credit card tour. But it's another reason to "ride light" over bumps and tracks as others have suggested.

The relative tube weights in this flyer are interesting: Reynolds 531P was about 10% lighter than 531C.
