I purchased a potenza groupset from Vanilla bikes. Their price was especially attractive, even allowing for postage to Australia and their service exemplary. There was an issue with Campagnolo changing the spec of a component that Vanilla recognised and advised that it would be better to wait until the new model arrived. Bottom line was that I paid for the 2017 model and got the 2018 model - no extra cash asked for. Vanilla's communications are excellent. And the Potenza groupset? It's a work of art!
