The new bike will be built around a Velo Orange Campeur frame. I had imagined a proper rigid steel frame– non-disc and not suspension corrected– that would fit a 2.1″ tire and a fender. It does not exist, but in considering the available options with long forks and mountain bike geometries, I reverted to more traditional designs. The leading options for such a bike in a competitive price range are the Black Mountain Cycles Cross, the Surly Cross-Check and the VO Campeur. All satisfy my demands, but with slightly compromised tire clearances. However, as I envision fast riding with a lightweight load a narrower tire will suffice. Living in New Mexico for the winter, I will forgo fenders in trade for increased tire clearance.
Casey and Igor at Velo Orange tell me that the large frame sizes (59 and 61cm) will fit a 700x45mm Panaracer FireCross tire, barely. Given the aggressive nature of this tire and the tall side knobs, I am hoping that a smooth 45-50mm touring tire will fit. I do not enjoy fitting tires, fender and racks where they do not belong, although I cannot imagine exploring the rural dirt roads in this area without at least a reasonable cushion of air. As long as I have the Pugsley, aggressive traction is not an important feature of this bike, but a reasonable tire volume is.
It is my impression that many of the Schwalbe touring tires that I adore (Marathon, Supreme, Dureme) are undersized relative to the advertised sizes, which is good news. Some of these tires labeled 47 or 50mm may reasonably fit the Campeur with some room to spare. On such a tire, on such a frame, I expect dirt roads to disappear under me. Rough doubletrack and some singletrack will be rideable at a passable, touring pace, and pavement won’t be a problem. With 47mm tires, this bike will be much like my Schwinn High Sierra, but with the benefits of a larger wheel. I expect the bike to tackle great distances at speed in rural parts of the state. I’m hoping that this will be a fast comfortable road bike for real roads, in both town and country.
The frame is not yet in the mail and most of the build is not finalized, yet I have found two foundational pieces at a local bike swap. A NOS 36 hole Specialized front hub cost $5, while the Deore LX bottom-pull front derailleur was $2. For an extra $2, I bought a similar front mech for Cass as well. Thus far, these pieces are the basis for the new bike.
See my post from Interbike about the VO Campeur, including lots of live photos.
Cass has some Schwalbe Duremes that we can play with when the frames arrive. If they do not fit with a reasonable margin for a bent rim or some mud, I will look elsewhere. Here are some additional considerations:
Clement X’Plor MSO, 40mm (actual width, 38.5mm)
Michelin Transworld Sprint, 42 mm
Bruce Gordon Rock’n'Road, 43mm
Vee Rubber XCX, 1.75″ or 47mm
