research and notes: Nova Cycle Supply, Little Fish

Everest flat top fork crown for 1 1/8" steerer and 24mm road fork blades, $17

tube diameters from Nova:
Top: 25.4mm
Top/Down: 28.6, 29.5, 31.7, 33.0, 35.0
Down: 38.1, 42.0
Seat: 28.6, 31.7, 35.0

get some plain CrMo tubing to practice on....maybe practice lugs, too?

buy component gruppo now at shop discount, install when finished...price?

oversized tubing seems a good choice...does it limit lug options?

stainless braze-ons look good, harder to braze?

dropouts: add stainless faces, braze on eyes

Little Fish's 3rd frame CAD drawing shows regular (28.6mm) TT and ST,
OS DT (31.7mm)

Shimano 105 gruppo seems the way to go (after reading about why
Rivendell uses it)
debating between cantis and sidepulls, though. need to read up on
long-reach sidepulls.

Long reach side pull brakes will fit around a biggish tire - I've got one wrapped around a Ritchey 700x32C cross tire. But... there are a lot of buts.

1) But, you can't fit a fender under there. Yes, its possible with a smaller tire, but you still have the issue of squeezing the fender when braking.
2) But, you can't remove/replace the wheel without deflating the tire.
3) But, the brakes aren't really designed for the job. The arms are longer - however nothing else is changed to accommodate larger tires.

The brake works fine. It's on a frame made to test long reach, non-braze-on brakes. It's just a Tektro, and it stops and modulates fine.

On the other hand, the Paul centerpull on the back does all this more gracefully. And just about any braze on brake will step up another notch from the centerpull.

Based on all of this, I've given up on modern long reach sidepull brakes.

FWIW.
