I'm 98% complete in preparing my new-to-me 1978 Trek TX900 for the road.
Two years ago I sold my 1974 paramount, a bike I had owned since new. I also sold a Trek 400 that had become my frequently used sports bike for Chicago area rides. I had been searching for a suitable replacement when the TX900 was shown to me.
The TX900 was referred to me by the most experienced Trek collector I'll ever meet. It 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.
One issue to solve is that the bike was in Portland, OR. A Facebook friend responded to my request and became the facilitator. The bike was inspected, purchased and delivered to a Portland area LBS for shipping. In 10 days from initial contact it was in Chicago.
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 perfect.
The drivetrain is a mixture of Shimano Dura-ace and 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.
