Over the weekend I traded my chrome italian fixie (sold on the local craigslist) for a used il Pompino (bought from my friend steve). The picture above is taken on the first hilly ride after the build. I will elaborate on the whole story a little later. For now, here is the build list:

- on-one il-pompino frameset; on-one designed tubing, wish-bone seat-stays, 135mm drop-out, semi-compact geometry; 54cm seat-tube (though it fits like a 56 or 57cm); high bottom bracket shell. My friend Steve bought it used, and actually had bernie Mikkelsen brazed on some bits for him (derailleur hanger, downtube cable stops) and rode it as his trail-bike/commuter for a while. He has a soma doublecross now and decided to sell it for a good price. I won't bother taking the braze-ons off

- Soma Sparrow handlebar, the longer version
- Shimano UN-54 bottom bracket 68-107mm
- Shimano deore right crank arm, sugino left crank arm; 170mm, 110bcd. 40T/34T chainrings

My Touring Bike

I started to become more interested in doing various type of bike touring last spring. The only time i'd really do any type of traveling with my bike was the summer of 2005 when I was hanging out in the St Juan Islands in Washington State before starting my current job. I actually wanted to go to Vancouver, but since the immigration paper for my new job hasn't come through, I told my friend to leave me at a hotel in Anacortes so I can hang out on the islands. I had my fixed gear bike with me, and did some island-hopping (with the great ferry system) for 4-5 days and it was fabulous. Granted I didn't carry any significant load with me during that time, I enjoyed the experience of traveling on my bike.

I wanted to do a bike trip (haven't decided whether it's inn-to-inn or fully loaded) sometime soon, but I didn't have a suitable bike for it. my romulus could probably work, but since I already weigh more than 190lbs, i wasn't sure if I should add a full-load to the bike. So I sold my other road bike (90's specialized Epic Carbon) and looked around for a good used touring frame. I found a 84' specialized expedition deluxe on the local CL. After reading more about it and found that many people have high regards for the frame, I pulled the trigger and got the bike. It came with many parts, but for my purpose and preferences, the only part that ended working for me was the Sugino AT crankset and the 26.8mm seatpost. I began to gather parts for it and thought about wheel options. Here is the build list I arrived at, and pretty much still the same after almost one year:

- Specialized Expedition Deluxe frameset with special touring series tubes. These frames are built by Miyata with Miyata's own tube sets, and are very close to the Miyata 1000.
- Shimano 105 1" threaded headset
- Nitto Technomic Deluxe Stem. 12cm reach, 26.0mm clamp
- Nitto Randonneur handlebar which I got from Jitensha Studio here in berkeley. 26.0mm clamp, 45cm width
- White and Blue cloth bar tape
- Shimano UN-54 bottom bracket. English threaded, 127mm spindle length
- Sugino AT triple cranksets. 46/36/28. 175mm crank arms
- Crank Brothers Smarty Off-road pedals (although currently I am considering going back to platform pedals)
- Shimano 105 downtube shifting levers (8-speed) fitted to Diatech bar-end pods, making the combination 8-speed bar-end shifters (more on that later)
- Shimano XTR 960 series low-normal (reverse) rear derailleur (more on that later, too)
- Shimano XT low-pull (traditional) front derailleur, 28.6 clamp diameter
- SRAM 8-speed cassette. 12-30T
- SRAM 7-speed chain with powerlink
- Original 26.8mm seatpost
- Brooks black saddle (more on that later)
- Shimano LX canti-lever brakes with Kool Stop eagle claw pads
- Tektro R200 brake levers with quick release
- Mavic MA40 laced to Mavic front hub. 700c. 36h
- Salsa Delgado Cross Rim laced to Shimano LX hub. 700c. 36h (more on this later)
- Schwalbe Marathon tires; 700c x 28mm
- Nitto M12 cantilever-boss-mounted front rack
- Tubus Cargo rear rack (not mounted right now)
- Ostrich Boxy Handlebar bag
- Busch & Muller Ixon IQ LED headlight

Building this older frameset with modern components that I wanted or had was not without trouble:

- I couldn't find flat shifter boss covers (the piece that fits in between the shifter pod and the shifter lever) so I ground two oval-shaped ones flat
- I didn't realzed that XTR reverse rear derailleurs don't come with barrel adjusters, so I made one from old brake barrel adjusters. It works.
- The frame has to be re-spaced to 130mm, and then the LX hub has to be re-spaced to 130mm also (from 135mm).

So far I haven't done touring yet, but put about 2000 miles in the 10 months I have had the bike. Most of the miles came from training and riding the 2007 STP (seattle-to-portland) but since I have had fenders on it, the bike has also become my rainy day bike over the romulus. It rides really well, supple, compliant, yet not mushy at all. I was really impressed with the ride quality when I finished building it and took it out for a spin for the first time. Hopefully I can make good use of it as a tourer and randoneering bike.
