You are right. I was talking to someone associated with the trade and he told me that they are massive, only deal with quality stuff and everyone from
Evans, Halford,
Wiggle,
CRC, Cycle Surgery and nearly everyone with a quality bike would have something from them. Privately owned, very low profile, never advertise and in the mould of a traditional importer cum wholesaler. I looked at them and you can see that they have taken a vertical approach from the bars, frames and right down to the tyres and pumps, and all are quality stuff from Campy to god knows what else. And Leighton Buzzard is where is all happening.
I am sure others can provide more insight.
