Talbot Frameworks Tandem - Sik Fadez Family Chariot

This is why you can't have nice thing.

Main reynolds tandem tubes have arrived!
There's talk of shaping them using a custom die and two 10 ton press' to give this family chariot the all important Aero edge.
The other tube selection hasn't been nailed down yet.
No skinny tubes here.

frnar.

Mandingo would be proud of this tubing.

R785 shifters have arrived. Can't see why they don't brand them as Dura Ace?!?

i was with @scherrit the day after and asked who had been using the fitting jig for a bike so small

It couldn't wind in anymore. Smallest it went.
What are you getting fitted for?

The mamil chariot - my cannondale synapse. Plus it was an excuse to catch up with Corrine, Fettle and Tika too.

She's broken her wrist? And she still wants to ride a bike. Badass

Indeed! Did it doing a cartwheel! She insisted we go out for a ride last weekend too. Even wanted to carry her bike down two flights of stairs! Casts seem to come in any colour of the rainbow these days.

This makes me seriously consider a tandem for me and the 7 year old Lord of the House.

Brilliant, Luath 24 ride, as soon as I am fit again you have to show us some routes please?

Do it. She loved our old one! So much quality time together.

Sounds like an awesome idea :)

Matt's Anvil Journeyman tandem jig extension brings all the boys to the yard, because his jig, is bigger than yours.

After some time sitting in purgatory at Heathrow, and being lost by Royal mail, it's here!

Tube sample pressed and ready and being sent later today and jig extension unboxed.
Today is a good day. Full steam ahead.

Looks like a crank for @BareNecessities

Custom formed tandem chooooobs for aero benefits. Easily a two hander girth wise. So sexy.

hefty.

I hate to ask, but why? Wouldn't stiffness be your priority?

This will never be ridden at sustained speeds where aero benefits would come into play;) Stiffness is absolute key here and oval is stiffer than round. Plus, I dislike skinny tubed Tandems.

oval is stiffer than round

In selected directions. Presumably that's the drain pipe.

Look, I ain't no man of science. Pretty sure I saw something on the Santana site first then read a few discussions. No doubt, I've misunderstood to a degree. Matt's main man Tom is a man of science however (Cambridge physics grad) so I reckon between the two of them they'll get it right :)

I'd steer clear of advice from somebody who uses "efficiency" in that context without qualifying which efficiency they are talking about.
