Recent aquisition, built with Ultegra SL,open pros laced to 7800 hubs, Ritchey post,regal saddle, cinelli bar and stem. Takes 34.9 FD clamp, the beaurtty is in the tubes, bike rides well, the 42 chain stays coupled with the stiff steel is a great combo.
The Ultegra SL blurs the line between 7800 as expected. Not sure on the cage choice. Reccomendations appreciated.
