storing bike outside - avoiding trapped moisture and rainfall (bike covers) I just got a specialized tricross for riding in the city and going on short tours around Europe. 

Unfortunately I don't have enough space in the corridor of the house so I will have to put it outside in the garden. In the UK we have a lot of precipitation so I want to get a good bike cover. I was wondering if anyone can recommend me a special kind of material or brand for a cover. I know that one of the main issues is condensation so I guess it needs to be a breathable material. 

Is the Oxford Aquatex any good, does anyone have experience with this model or with the brand in general?

Any suggestions welcome! I want to take good care of my baby... :)
You know, I worry that marketing firms have brainwashed the entire world into believing that you need to spend a lot of money on fancy materials that are waterproof and breathable. Honestly, just spend a few pounds on a poly tarp and your bike will stay as dry as the day you bought it. Just be sure that you take the bike out to give it some fresh air each day so that you don't have to worry about condensation building up and causing problems. You'd still have to do this anyway even if you bought something expensive, no matter how breathable the salesman promised you it would be.
