The Bike, The Plan, The Project

What logically should have been the first post, now comes one week into this project.  The bike to-be will be used as a car replacement.  Recreational riding and light touring add secondary purposes.  Being slated as a car replacement dictates the bike be similar to a car in terms of reliability, durability and maintenance.

What the bike is not:  A hobby.  I'm not looking for another hobby, nor do I have any desire to learn bike maintenance in general, but I want to know my bike inside and out, hence the decision to build it myself.  Ask me anything about a derailleur and I'll look at you like a calf staring at a new gate.

Durability:  Steel frame, Rohloff hub and carefully selected components.

Reliability:  Comes from me knowing how to install, replace, adjust, maintain and fix every component on this particular bike.  It also comes from having high use parts on my garage shelf and all the tools necessary to do most repairs without waiting for a bike shop or delivery trucks.

Maintenance:  Little as possible, please.   Check the tire pressure regularly, change the oil every 3000 miles, new brake pads every once in a while, and tires when needed.  Am I talking about a car or a bike?

Here's a list of major components:

Frame  Soma Wolverine 54cm
Forks Soma Soma Wolverine Lugged Disc
Headset Cane Creek 110 EC34
Bottom Bracket Shimano BB93
Crank Set Middleburn RS8 X-Type 
Stem Kalloy Adjustable 
Handlebar Syntace Duraflite
Rear Hub Rohloff Speedhub
Front Hub Schmidt SON 28
Saddle Brooks B17
Chain Wipperman Connex 8sX
Chainring Middleburn Thick Thin 38t
Sprocket Rohloff 16t
Pedals NS Bike Aerial Industrie
Brakes Shimano LX
Rotors Avid G2 Cleansweep 160mm
Computer O-Synce Macro High X RC
Ant+ Sensors Garmin  Magnetless
Rear Rack Tubus Logo Evo
Fenders Curana C-Lite 
Headlight B&M Luxos U
Tail Light B&M Toplight LED Line Plus
Tires Schwalbe Marathon Supreme
Wheels Rigida Andra 210, 36h
Spokes DT Swiss Competition
Skewers Shimano Deore SLX
Seat Post Soma Layback 350mm (Black)
Grips Ergon GP-1L for Rohloff
Kickstand Pletscher Double Leg

The original plan was to employ a belt drive through the Wolverine's belt-compatible drop outs, but Rohloff, Gates and the Wolverine don't mix well.  The frame is a touch too flexy for the required belt tension when added to the hub's torque.  If/when the Conti belts become available to retail outlets, they will be worth a look.  The Continental belts have longer teeth requiring tension similar to a chain.
