This was my first customized build.
Bought from the proceeds of a RIH frameset I turned into a ‘fixie-conversion’ and sold on.
It had a Dura Ace 7400 group on it, but the left hand shifter was not functioning well, so I upgraded.
I got a DA 7400 seatpost and headset, and put DA 7700 on, the same as Rabobank used.
I’m not sure if it’s an Slx tubed ‘Spiral Conic’.
It was without a Columbus decal when I got , so after looking around on the net,I saw similar bikes entitled ‘Spiral..’
that did not have the crimped down tube normal associated with the model, hence my assumption.
I should really undo the bb to look for the tell tale internal spirals.
I changed the saddle to a rolls, my butt couldn’t get on with the Brooks on longer rides.
