Fixing hub gasket squeal
At 200km you should be able to take the bike to where you bought it for a free tune-up to adjust brakes and derailleur indexing etc.

Ask to have the front hub looked at as it definitely should not be making noise and will be covered under the warrantee. The problem might be fixed by lubricating the area around the rubber gasket, but you want to make sure there is not a problem with the bearings.
