Triban 3 here as well (2 in this household).
Have had to make a few changes to mine, shorter stem & narrower bars with me being female, added a pannier rack for commuting and SKS mud guards. Added cross levers + new brake blocks almost immediately (I have grip issues in my left hand so needed the extra braking ability cross levers offer).
Tomorrow she gets a new chain, after somewhere near to 1,900km (since 1st Sept 2012) I have worn the chain out and there is some play in the rear wheel, so suspect the hub - someone else who need to know how to re-grease the bearings. Hopefully the cassette will be OK otherwise she will have to have a some money spent on her.
