This TX900 has everything I wanted in a C&V bike, including: Columbus tubing, 3x6 drivetrain, 700c wheels with Campy NR high flange hubs. The fact that the bike is an American brand and that the frame size is XXL is perfect for me.
The frame size is 65cm c-to-c by 60 c-to-c. The stand-over is snug but the reach from the saddle is just right.
The componentry is mostly a mixture of Shimano Dura-ace & Deore XT! The crankset is SR Apex with 52, 40 & 34t chainrings. The pedals are Suntour Superbe. The headset, brake levers, brakes and shifters are Dura Ace. The hubs are high flange Campagnolo NR 36 hole, the rims are Mavic . The odd-ball drivetrain must have been added to the frameset in stages. Chances are that the Dura Ace bits were installed on the frameset when the bike was new and the other items were added later. I consider the drivetrain to be ideal for hilly century rides, so it will remain.
