Jack is Rapha's lead designer and ordered his Mercian a while ago. Below is his email.

It was nice to catch up at Bespoked in Bristol. Congratulations on the best utility bike as well. Totally deserved!I just remembered i said i'd send over a picture of the complete bike.I'm really pleased with how it's turned out. I dont think it's necessarily what people expect when they think of Mercian? I normally picture something more classic, barber shop seat tube and thinner tubes etc. But this is a lot more modern looking (just as i wanted!) It's been a pleasure to ride so far. It feels smooth and very responsive.pass on my thanks to the guys in the workshop, they've done a great job.All the bestJack
