Pearson will build you a bike to match you based on the framesets that they have - the main bits of my Pave were chosen by/fitted to me, or selected by Pearson from their parts to come in budget.
I am sure I could have got a cheaper bike off the peg, but then it would have said Specialized, Giant, Trek, Cannondale, Boardman on the frame but I didn't want that but wanted something different and made for me - hence the Pearson. I didn't have to pay extra to fit narrower bars, a shorter stem, a ladies saddle etc etc
If you have a good sized budget they are very good - their newish Sheen store caters for the higher end.
Most of the frames are made in the same factories but you get a less ubiquitous paint job - that said, I do see a fair number of Pearson frames around, but that's because they've been in Sutton since 1860!
