26.3 seatpost on '78 Dawes Super Galaxy?!

Hello all!

I have just bought a classic Dawes off gumtree here in London. I have a 34inch inseam and REALLY need more than a fistful of seatpost... but where can I get a 26.3 seatpost?

The post it came with is alloy, marked 'BIRMALUX Made in England 26.3mm DIA'. I am assuming it is original fitment because of the Brooks B17 saddle date stamp 'A 78' - Jan 1978 (and the massive dangerous-looking grooves from the saddle clamp).



So what do I do for a useable seatpost? Any cheap sources in Europe? How many layer of aluminium can do I need to shim a modern one?

I'll be requesting Sheldon B to add this to his database as soon as someone tells me I am not crazy.

Thanks for all the expertise on here - I am now the proud owner of 2 unrideable old bikes, 1 classic, and a beater.

Cheers, Prav.

wow I have never seen one. you can use a 26.2mm post without a shim. 0.1mm is not a big deal. I often find bikes with 26.8mm posts from the early 80s where there should be a 27.2mm I think there was a shortage during the transition period when most high end bike became 27.2 and there were all kind of leftover 26.8s or something.

In the other direction, 26.4mm LaPrade-style seatposts are common as well. They were stock on late 70s Raleigh lightweights, and I've seen those SR/Raleigh post come up on eBay quite often for reasonable price. You can sand that down slightly or lube it and hope for the best.

Cool, a 26.2 post will have to do I guess - LOTS of choice! :-)..
I just don't want to mess up and stretch the seattube on my only nice (531) bike, and I'm not a small lad (6'3" 90kg).

So you reckon a 26.3 is valuable to the right guy? its scratched to s**t - as you can see from the pics. I've got to get one of the gouges on the post from the saddleclamp - I rode it home 10 miles! eek!
