If anyone needs to have confirmation about a specific bike or frame, then the first thing to do is to ask the dealer who supplied the bike, as they should be aware of any issues.... or at least they can check through their supplying national distributor.
If that isn't enough contact Tern directly through the global website ( ternbicycles.com ), and the enquiry will be routed to people who can give a definitive answer.
Lastly, and primarily for the UK, I am happy to be contacted as a last resort.... and will always do my best to help get answers and action where required.
