In France. Gosport in Annemasse just across the border. Do not buy in Switzerland. 2x as expensive. Or if you are going upmarket, drive to Lyon and buy there. Anywhere but Geneva.

buy in Decathlon

Oliver. As my bikes always get stolen (or the last one was run over with me on it) I use the fourriere in Petit Sac.  Have onlyx been twice and out of the choice there has only been one that suited me but you can buy for 300-600 francs.

You can even buy Swiss army bikes but they have no gears. 

I did once buy in Gosport in France and was not impressed.  And of course you could always start off by buying the wheel you found and build your own bike 

Plenty of keen cyclists buy their bikes in Geneva.  It is just less hassle unless you are always going to France to shop

You can get some pretty decent ex-hire bikes at not bad bad prices here .

A whole bike, I don't know... However, if you are interested I have a Ksyrium Equipe S front wheel in perfect shape I can sell you for a very good price.

Thats ok.... i just sourced one yesterday..... do you have a back one :) ???

My current bike is a Decathlon Btwin Triban 5... great starter bike but Im looking to upgrade to something a bit racier....... trying to find a bargain on a great second hand carbon bascially... might be looking for a while :)

They have some really good deals in Veloland on second hand bikes.  Just depends what they have in at the time, always changes.  But they have some high quality second hand bikes at good prices. Worth a butchers.

Ooooh this looks interesting, thanks TogJay....

Royle - I bought a 50chf mountain bike from there last year to get around town so will have another look to see if they have anything better... Thanks!

Still trawling through the new pages of petiteannonces.ch daily looking for that bargain race bike.... At the moment I have a good friend in UK offering me his upgraded Specialized Tarmac 2012 for 1000gbp, though I would prefer to find something here, 

Is anyone looking to upgrade or get rid of a sexy road bike? thx

Thanks all the help, ended up buying a great Cannondale Supersix for a good price on Petitesannonces.ch , very happy with it and will be on the roads very soon, 

If anyone wants to take my 2013 BTWIN Triban 5 off me (also for sale on classifieds) I am open to offers as wont be using it, 

Thanks, 

Oliver
