Paragrafrytterklubben -- Principia appreciation

I picked the bike up on Monday near Derby. I met the widow of this man, whose bike it was. http://www.cyclingweekly.com/news/latest-news/cyclist-killed-10-mile-time-trial-named-72-year-old-founder-local-club-335992

Sad times

Better pictures of my rs6, with second wheelset from @sykodrama:

nice!

Aces! :)

Very nice, not fussy, simple and clean. Somehow the green tyres even look good...

@PhilDAS @sykodrama @doubleodavey

Thanks all!

IANAPWB but doesn't wear on the anodising like that suggest over tensioned spokes?

walks away

Haha, if so, my fault, the wear happened when I had built them, @sykodrama is only responsible for the rebuild :)

Also, note the opposite wear pattern on front and rear...

I always thought that the front wear pattern could be explained by the fact that braking on the rim pulls on the spokes under the brake, and since they are radial, the rim will always be pulled slightly towards the brake pad just where the nipple is.

Very very nice. Always loved principia’s

Sorry, didn't mean to cause offence.

@Sveinung yeah interesting how its reversed between the wheels.

Someone could probably explain it, @mdcc_tester or is it @scherrit that builds a lot of wheels?

Thanks!

I don't think you did :)

Would be very cool if either of the two would care to comment, are they alerted by mentions like that?

doesn't wear on the anodising like that suggest over tensioned spokes?

No, they all do that sir. It's because the wall of the rim is thin and the shape is poorly designed to transfer spoke tension to the tyre bed, so it bulges and dips as the spoke tension tries to pull it out of shape. It's typical on pretty much all tubular rims which were made from a squashed round drawn tube rather than being extruded to their final shape.

are they alerted by mentions like that?

Yes :)

Ah ok, I maybe read that it was the spoke tension that did it and inferred the 'over tensioned' part.

Cheers.

Wonderful, thank you for clearing that up! (For the record, the front rim is a Mavic CX18, the rear a GP4)

Recently picked this up to use as a winter build (seller’s photo) . It’s a 2004 RSL -AS which is basically an RSL but has clearances for mudguards and slightly slacker geo. Came with a full carbon ITM fork and principia headset , which are supposedly made by Chris King .

Thought the colour, called “Oasis Green” looked a bit like ti in the photo but in reality it sits between dirty gold and a metallic turd, depending on the light! No that keen on it tbh, but seems a shame to respray as after cleaning it up the anodising is in excellent condition with barely any marks. Leaning towards silver over black groupset ..

Good looking bike. Does the raceface seatpost have integrated cockring?

Ha! Yes apprently so and it's for sale if you want it. :)

Here is my 2006 revolution in anodized black. I currently need to replace the Principia 3d headset which I will have to order in from denmark. It currently weighs 7.71kg.
My old RCS s6 is up for sale https://www.lfgss.com/conversations/312865/#comment13987423

Found some info on Principia, storing the links here for future reference/anyone interested.

Exerpt from the latter, about what happened after the bankrupcy:
Principia of Denmark
"Principia of Denmark owns the rights to the Principia name in the Nordic countries and the rights for the original drawings and and the the technology behind the original brand. They have kept the original design while some things has improved tells product mananger Jens Leth.
...The interest in the new frames has been great and we have already sold 25% of the planned production of carbon fiber frames. A Danish Principia will be equipped with a newly developed superstiff carbon fork. There will also be Principia wheelsets and Principia tires.
...The alu frames will be made in Principias own alloy, Principia Magnum Tubing (PMT), an alloy which according to the manufacturer offers more comfort."
Principia International
Principia International is another company with the rights to the name Principaia. Not in the Nordic countries, but in the rst of the World. This will primary mean USA, England and Germany which traditionally have been important markets, but also Holland, Italy and Austrailia and a number of other countries has an authorized dealer.
This company also owns the original technology.
They have also developed their own carbon frames and also developed the alu frames further...
A Sicilian offer
The reason why theres two different brands with the same name but different model programs is actually quite simple. Lars Hjort was the man who bought the rights to Principia after the bankrupcy in 2004. Later he sold off the rights to the Nordic market. "I got an offer I couldn't refuse from Dan Bike inc. which is a part of the HF Christiansen inc. http://www.hfchristiansen.dk which is the company who is now behind Principia of Denmark. This inc. also owns the rights for Nishiki bikes in Denmark and hence has experince developing carbon frames. The Nishiki frames is also part of the test of Danish carbon frames in this issue.
Confused?
If not, here's a littel twist to the story. Principia International with Lars Hjort owns the rights for Boreas, a brand which already has a history tied into Principias history. "The price for the rights for Boreas was in a whole other and much lower price range than Principia" tells Lars Hjort. Under the Boreas brand Danish buyers has accees to a program of carbon of alu frames like the two Principia brands. A critical look at the Boreas frames reveals strinking similarities to the corresponding Principia International program. So with a Boreas caron racer in the test there called for "Battle of the Principias" in the Danish carbon test elsewhere in the magazine.

^ good investigative work!

A more up to date shot of my tt2

I've had a TT28 frame in black for a bit, it was a forum purchase that never got built. I recently resurrected it, gave it a clean and put some forks on it.

I then put some parts I have been collecting on it.

Not far away from getting all the bits together, some finishing kit and cables yet to arrive.
