Ten years ago, I built a Road/Sport frame designed to use a simple 1x9 drivetrain and a single shift lever. A few weeks after it came back from getting a durable powdercoat finish, that bike and I began a supported transcontinental ride from Seattle to Boston, with an improvised victory lap around Nova Scotia. I loved that bike. It climbed the Rockies, it turned South Dakota into a blur (well, maybe the heat helped that), it went fast when the big boys decided to play, and it was stable under 20# panniers at the end. Two years later, I used that bike to follow the Lewis and Clark route from St. Louis, MO to the Pacific Ocean, and, once again, it was just perfect - simple, reliable, and comfortable. Back home, it became my favorite bike for group social rides, centuries, and a variety of supported and credit-card tours.
Five years ago, I built a replacement frame, using the same geometry and tube set. But this time I carved a set of Pacenti Artisan lugs (not yet available the first time) and sprung for a gorgeous Joe Bell paint job. The first frame had been a plain workhorse, and, even though the components were all the same, there was something about the new frame's beauty that made the ride even sweeter. This was still going to be the lead dog on my sled.
Shortly after finishing the "beautified" 1x9, and without proper warning, my cycling preferences took a sharp turn toward fat tires, low-trail geometry, riding in "normal" clothing, and adapting to an aging body. I rode my 650B bike the most, and tried out (and liked) Albatross bars on it and on my low-trail 700C loaded touring bike. I bought clothing from Rivendell. I swapped my SPD pedals/shoes for naked cage pedals and sticky-soled Adidas flats, and re-discovered how pleasant it is to ride with free feet. I confirmed that the social riders at the back are laughing lots more than (and often about) the racer wannabes out front. Cycling life was good. In September, it dawned on me that I had not taken the 1x9 off the hook at all this year. Oh no! This called for a makeover.
The photo above shows my 1x9 in its reconfigured state. The component changes include a Nitto moustache handlebar on a shorter 8cm stem, light cage pedals, a lower tread-width classic Dura Ace crank, and a slightly smaller (38T) chainring. The frame was built for standard reach (47-57mm) caliper brakes at full slot, which easily accommodated the new wider (700c x 35) Panaracer Pasela tires. With the same old 9-sp 11x34 cassette, the gearing ranges from 31 to 95 inches.
Equipped as shown, weight is 21lb -12oz. I'll hang a candybar bag on the bar, and there's also a small custom rear rack if necessary.
Medium-trail steering geometry (originally built for 28m tires) seems OK with these new wider tires. The new "head up" body position tends to lighten up the front wheel, and the effect of some extra pneumatic trail seems to counteract that lightness.
I also milled the DT shift lever and its mounting base to change the lever's orientation on the bar-end mount, such that the lever points straight back (instead of 45* up) when the chain is on the largest cog. This gives a much nicer hand position on the shift lever when the bar-end is this high.
After 10 years of riding this drive train without a chain keeper for the single chainring, I finally installed a Paul unit. I need to fabricate a keeper that's not so bulky, and silver.
