Threading gauges! Joke apart, check this and Sheldon Brown's entry for threadings. For English threads you can count (with some patience) the number of peaks per inch as is explained in the first link.
Being probably a custom ordered bike, the type of thread used might have been the choice of the original owner of the bike: Any idea about how old is the bike? Spanish bikes, as far as I know, used either French or Italian threadings in the 70s and 80s. The French threading became relatively obsolete (apart from France) by the end of the 70s, as the ISO standard became the reference for the components industry. My bet is that, given Zeus reputation for Campagnolo knock offs, chances are that your fork has Italian threading, assuming it's the original one.
Hope it helps

Pretty ingenious way to do it!

All cogs are equal, but not identical...
Once I bought a cheap cog to try a higher ratio than the one I usually ride and, when it arrived, the threads of the cog were so badly done that I never dared to fit in the hub: it didn't screw smoothly more than one turn. The last thing you want is to ruin a relatively expensive hub (and wheel too) just to fit a crap cog. Apart from that, there are also important differences in terms of the quality of the steel, of the machining of the teeth, weight, etc...
A Shimano cog will sort you out for 15 quid.
Not as shiny as the EAI, but well-finished and reliable. -

Just following a similar thread on other forum with first hand experience of people who have fitted the exzentiquer BB and it seems that it works fine for ss. The cranks have to be hollowtech. If fitting a MTB crank, you may need to file the inside part of the crank where the granny attaches as, I believe, this exzentriker BB is designed for road cranks with two (not three rings). Still, for the price it retails, I will go for the ENO hub, specially if you are going to run it on a fixed where there is no problems with rear brake going out of placement.
A couple of pics to see an actual installation of the exzentriker BB on a ss -

If you are not too concerned to maintain a tight clearance at the front, it is probably worth getting a good old chromed road fork drilled for a brake.
PS. If you want to get in contact with other fixed gear riders in Spain, visit our modest web page and forum at simplifika.tk (although it's been down lately). Alternatively, you can post any question on the classic bike section of the foromtb.com where there are few single speed and fixed gear enthusiasts too.
Good find.

If replacing, which I would recommend, first check whether they are long or short reach, bets are that they are the old, long reach callipers. Think you can mount the recessed allen key fitting calipers, but alas since these are normally modern short reach, you might not be able to fit them there. Just measure the diameter of the fork steering tube, to know length of the fitting you need.

Been there once. The guys are quite friendly and will let you have a look to all the piles of stuff they have there: it can be a good place to source parts for a pub-bike but don't expect to find any treasures....loads of donated cheap halford-style MTB. No road bikes when I was there, though.
Worth a visit if you live in the area and looking for parts. -
A guy with the same phone number is also selling this RidgeBack Horizon. Here the description seems more legit http://www.gumtree.com/london/78/23567878.html but you never know.....

I always love the old plain cloth handlebar tape like this one: enough gripping to your hands and also to handlebar + you can always wrap / unwrap it with out ruining it ;-)

I have always found their 2nd hand bikes overpriced. The staff is not particularly friendly either. When looking for odd bits, they never let me have a look at the piles of stuff they have at the back of the shop and always tell me to come back Saturday morning.
To be fair, however, I managed to persuade them to let me have a decent peugeot road frame for 20 squid, but that was back in 2000 and there were under different management.
I have always wondered how they manage to do any profit... -
Lol, is that the original frame you got with the unipack?
If so, it certainly looks good (not the horrible aluminium frankestein bikes I saw on the unipack thread) The chromed rear triangle, as well as the track drops, speak of certain quality....
Stupid question: with the pics below all makes sense now
