The bikes you have listed are all rear loaders, front loaders with have steeper head angles and more rake.
Tire size also effects front end geometry, fatter tires require less trail.
Measuring frames off the building jigs is notoriously difficult.
Rack stiffness has a large effect on handling of a loaded bike, racks with poor triangulation can make an otherwise
good bike handle poorly when loaded.
Bike setup effects handling.

Re: Which handlebars for 1960's rebuild
Nitto makes very fine quality traditional looking bars and quill stems.
Some Nittos have the centre sleeves, the super light versions don't.
The Gran Bois Phillipe bars are Nitto superlight.

Re: pc10130 chain splitting?
From SRAM concerning their 10 speed chains.
PowerLock
SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect our 10 speed chains. While PL does not require special tools for install, the especially tight tolerances of 10 Speed drive trains mandated that each PowerLock is good for a one-time application only.

You are worrying about grams and riding armadillos ??, I have lorry tires with lower RR than armadillos.
Which brings up what pump are you going to use to add air to the tires everyday ?, one that won't rip out
a valve when you are not quite awake in the morning. (I bought a Mountain Morph while touring)
Standing around waiting for patching or carry several tubes between you and patch in the evening, which is faster ?

Re: Freddie Grubb restoration
IRD makes new 5 speed blocks, google Interloc Racing Design.
Suntour made Ultra 6 blocks, narrower cog spacing, but still fits a 120mm hub.
I'm using one with a Benelux Mark7 derailer, works fine.
Simplex stuff is extremely popular in Japan so Ebay prices on excellent condition stuff can get silly.
British bits go for less, the Benelux Mark7 is as good as Simplex, the Super 60 requires a special
tool to adjust the cage tension.

Re: My new (1950s) tandem
The crank being farther out ?, maybe the spindle is for a bike with a chaincase.
The headclip is looks like 1.5in, they do show up on Ebay every once in a while and go for silly money.
Good news is the races are heat treated and very very long wearing. Headclip stems are different,
no expanded bolt in the stem, the bolt on the top race clamps the stem in place, you can use
a regular stem with the expander bolt removed most of the time. Some headclip stems are
22mm in diameter, instead of the modern 22.2.
Phil Wood does odd spacing hub on request, 40/48 hole hubs for freewheels are available.
Tektro does long and xtra long reach dual pivot brakes, new levers are highly recommended.

Old ??? I think not, the problem is the bike is too new. Find a shop with mechanics older than you and have
them fit a good vintage chainset. A Stronglight 49d or a TA ProVis with smaller rings, 46/30 is a good combo.
If you want to use current stuff a "compact" with 48/34 would be a decent choice.

Re: The difference between a "Sportive" and an "Audax" bike
DavidT wrote:I have always understood that an Audax bike is essentially a "fast tour" bike? Essentially based on racing geometries but with a bit more comfort, the option of fitting accessories such as mudguards and racks, and a wider gear range.
If you get to the French inspired version of Audax, the geometry is different to accommodate the handlebar bag,
the accessories aren't, they're permanently attached to avoid bits rattling loose. The frame is built to be more
flexible than a racing frame, no sprint points in Rando and the riders aren't putting out Pro levels of power.
If you have been riding for 40+ hours you don't want a skittish or stiff bike.
This is the way it was done back in heyday of Rando and the Technical Trials in the 1940s.

Re: Jerseys: Sportwool Vs. 100% Merino
100% merino s/s Jerseys, excellent quality, the pockets will sag more than a Rapha.
The colour bands are woven in, not pieced in like Rapha.
The trainers are like a mid weight sweater, embroidered not flocked, lovely stuff.
No French designs, the owner has it in for the French.

The sizes are about 1 off from Rapha xxl = xxxl in Woolistic.

Re: How to classify club rides
Fast rides, you see the team car and the Belgian domestiques lined up.
Speedy ride, skinny people in lycra fiddling with heart rate monitors, skinny tires, no saddlebags, all non-ferrous bikes.
Moderate ride, Old guys on old bikes, some grey hair, lots talk about where to stop for coffee (cake stop in Brit)
Fun ride, lots of tweed, chaincases, people sitting upright like proper gentlefolk
and the lovely tick tick of Sturmey Archer.
Rides to avoid, people wearing wool, with french handlebar bags and very shiny hammered fenders,
they're going for a quick 400k lunch run.

Freight trains have priority over Amtrak (passenger trains), so Amtrak trains can have long delays,
you sit on the track and watch endless freight trains crawl past you. Greyhound (bus) is more reliable
and they will take boxed bikes. US airlines see bikes as a revenue source, they figure you'll pay silly
money ($140 one way) to ship your bike. When traveling to a tour here, I ship the bike via UPS
and fly, at least my bike will get to the start of the tour.
