I, and my fixed, made our maiden voyage over the weekend in a 109km Audax - makes a change to my Rohloff!
It's a Pearson Touche 2010 using a 48x19 (20 on the other side), with Ultegra brakes, Halo Aerorage wheels, Selle SMP Evolution seat, Continental Ultra Gator Skin 700x25 tyres. It's been to
Bike Dynamics for fitting which resulted in the seat height being lowered by 2cms(!), fitting a shorter stem and a change of handlebars.
Currently contemplating changing the chain ring for a steel one and perhaps opting for something smaller. Also tempted by upping the tyre width to 28mm to help take the shock out of the ride.
