I'm emailing to let you know how pleased I am with my Mercian frame I
had built up last year. For the past 10 months I've been riding it on
cheap parts I had lying around but have now rebuilt it using some far
better components to really do it justice. It's such a dream to ride,
feels really solid and composed. Its a 631 with Shimano/Dura-Ace
parts, Brooks leathery bits and Nitto bars/stem. Most of the time I
ride it with the freewheel for longer distances. I've never owned a
bike before that actually turns heads!

Thank you Martin for the email and pictures. Please note Martin has had the option for fitment of 2 brakes. Either for fixed or freewheel.
