Joe Bike's own Soma Wolverine Daily Grinder housebuild features all the things we look for in an ultimate commuter bike: belt drive, internal gearing, robust tires, and disc brakes, along with an optional dynamo system, fenders, and rack.

Together these give you a weatherproof, clean, quiet, ultra-low-maintenance bike that's ideal for less-than-perfect conditions. Fully rack- and fender-friendly. Semi-sweptback handlebars give you a slightly more upright position than flat bars will, yet still lets you put your impressive strength into your pedalstroke.

The 46/22 gearing with Alfine 8 is set up for moderately high-speed riding on your typical mildly hilly Portland terrain (excluding the west hills, that is). However, if you'll be hauling some weight with you, climbing steep grades, or just wanting to take it easy, we can lighten this up by using a 24t cog...or even a no extra charge. Just ask.

And now, we can build the Daily Grinder up with drop bars, thanks to the recent appearance of Alfine-8 bar-end/downtube shifter from MicroShift and an integrated shifter/levers from Portland's own Gevenalle. Get in touch if you're interested.

We're also offering now an 11-speed Wolverine Daily Grinder with dynamo system, rack, and fenders, based on the new v3 frame in red or black. Or you can have us build the same specs using a v2 or v2.1 orange or black frame, subject to the availability of your size and color. You can see pictures here of an orange one with gumwall tires. The 11-speed versions are actually less expensive than the 8-speed, and that's just a function of the super-low price on the complete 11-speed build kits we were able to get.

We can also do an Alfine 11 Wolverine with drop bars using Microshift's STI-like 11-speed shifter.

Questions people ask us about this bike:

Q: Don't I need to adjust the belt tension every time I reinstall the rear wheel, such as when I change a flat?

A: No. Soma, along with a few others, "gets" belt drive and have designed their dropouts accordingly. In this case, Soma uses Paragon sliding dropouts. The only time you should need to check and adjust belt tension is in the future, when the belt teeth gradually erode and the tension therefore gradually slackens. This adjustment is easily done on the Wolverine, and you won't have to do it for maybe the first 2,000 miles or so, although this depends on your riding style.

The Portlandistan version adds a premium dynamo system, stylish Full Metal Fenders from Portland Design Works, and a light but stiff Axiom Streamliner Disc DLX rack, which has twice the capacity of most racks.

Q: Can I make substitutions or other changes?

A: Sure, but the price will likely change. We sourced build kits at a lower cost than you'd expect, and that's reflected in the surprisingly low price of the bike. But just let us know what you have in mind (email is best).

Q: What are some upgrades I should consider?

A: A Brooks Cambium or leather saddle would be nice. Either PDW Whiskey leather ergo grips or Ergon Biokork ergo grips would make good sense. If you want to charge your smartphone, Garmin, or camera off of the dynamo system, the Busch & Mueller Luxos U headlight does that very well, although it's expensive ($258). Kickstands are highly underrated. Schwalbe Marathon Supreme tires would make you the customer of our dreams.

The Portlandistan build adds the following:

An expertly handspun front wheel based on the Shutter Precision PD-8 dynamo hub, among the best in the world.

A Busch & Mueller IQ-X Premium front light, which will probably be the best light you've ever experienced. (Luxos U, including a USB port to charge your smart phone or other device, is available for an additional $100.)

A Busch & Mueller Toplight Line Plus taillight with wireless brake light.

Axiom Streamliner DLX Disc rack, with a payload capacity of around 90 lbs. yet light and stiff.

Portland Design Works Full Metal Fenders, city width (45 mm).

And of course all the labor.
