Just in case for example the vitus frames sent to the states compared with the ones that went to south america had big differences in the bonding and forks for example.
I know roads are different here than in S/A but what we noticed back in the day was that the ALAN forks that came to the states were reinforced internally. The ones that went to S/A and maybe europe were not, so after a year probably the fork needed to be replaced after a nasty accident.
In my country and we checked experience with colombians, argentinians and brazilians and for them as for us all Vitus and Alans after 2 years max, in some cases like sprinters after 6 months some tubes were unbonded badly, the ones that came to the states were taking way long to have a problem in the bonding. Probably with the years the bonding got better but the american market is so big that many products have to come with better quality or the loss it is too big. Who cares about 100 frames per year market when in the states u sell thousands. so thats the market u need to take care off.
Good luck with that frame anyways, are good stuff...
