Paragrafrytterklubben -- Principia appreciation

Thanks! Fairly roomy then, maybe would fit 25 on wide

Is it a standard headset? The listing recommends a replacement

tapered, 1 1/4 inch and 1 1/8 inch

my LBS replaced either the top or bottom bearing with a BB bearing (I think).

I think that it is a rebadged Chris King headset, but not totally certain on that

I've made an offer...

it's not on ebay anymore....fingers crossed for you

Still there for me and a pal who I got to check in a wild panic

sorry! was looking under bikes and not frames...

Sold for 135quid, I made offer for 175 with postage but got rejected.
Dibs if you will ever sell it.

Noted. I won't hang on to it forever. Really excited now though, need to start cobbling together some nicer bits!

Congrats!

FYI, I run 27 mm Challenge Paris-Roubaixs on my RS6 Pro.

Awesome, good info thanks

My Frankencipia or Cannoncipia. Forks come from a C'dale after I smashed original ones on a car. Just fitted new Maxxis tires and longer steam which surprisingly came with more comfort. Still want t

Wow. Wish you hadn't posted that, looks like I've overpaid for the ebay one. That's a better frameset (I think? brochures are hard to decipher at a glance), with a services headset, for less £££

principia tt6 light on eBay.

never heard of that model before

Here’s my principia rsl (1994) nice anodization on this 1 :) bought it with a wound up fork in it and tuned some parts and put light parts on it to get it at 6.97 kg. Best bike I’ve owned so far (and I’ve owned lots of bikes...)

Here’s my ellipse SX currently at 5.88 kg (without pedals and bar tape) but also with some heavier part still. Don’t know how it drives copped for 220€ with chorus 10 speed group. Than started looking for lightweight parts to do a budget weight weenie project (sub 6kg for sub800 euros.) crafted my own outer cable set that weighs only 19,3 grams :D still looking for titanium skewers and have to stick some other wheels in.

An other principia RSL (probably 98?) picked it up really cheap, will start the project when my sub 6 ellipse principia is finished :)

This is really stunning, great work on the build.

welcome @HubertEverts!

Lovely!

Can anyone advise me on what size seatclamp I need for my Rex e SX? It's measured at 35mm but that seems very rare and 34.9mm seems very common

Thanks all! Im almost finished with the Sub 6kg Principia ellipse SX, will post pictures later :)

@alialias 34.9 fits, since the seatpost clamp can be opened 0.1mm doesnt matter. (thats porbably the tolerance on those things anyways.)
