Joe's Wolverine

Introducing our complete Soma Wolverines




After building up a wide variety of Soma Wolverines for a wide variety of customers, we decided to offer complete Wolverines in three flavors. There’s the Daily Grinder, the Gravelo, and the Weltgrinder Rohloff. If you guessed these are optimized for commuting, gravel, and touring, you’re right.

The Wolverine is now available in a flat black as well as the orange. It’s also now available in size 62, though at the moment quantities are very limited.

The Wolverine Daily Grinder, shown below, is a belt-drive, Alfine-8 commuter with hydraulic disc brakes. The semi-sweptback handlebars give you a moderately upright posture that make the ride sublime. It really is a different, calmer experience than riding the same bike with flat bars. (If you want flat bars, though, we won’t “steer” you away.)

Here find more narrative direct from Soma:

The original inspiration for the Wolverine was “monster cross”, but it is seriously so much more. Its geometry is stable enough for off road touring, but sporty enough for all-around adventure. With its Tange/IRD Split Sliding Dropouts, you can turn it into a single-speed CX bike. Plus it is compatible with the Gates Carbon Drive.

– Clearance for 700x45c tires w/ fenders

B&M Lumotec IQ-X

A new champ among dynamo lights: the Busch & Mueller Lumotec IQ-X


Busch & Mueller have outdone their top-of-the-line Luxos headlights with the 100 lux IQ-X. This is the most powerful dynamo headlight we know of.

iq-xHere’s the IQ-X at 100 lux…

…and below is the B&M Cyo Premium at 80 lux.

Cyo Premium at 80 lux


…and below you’ll see all the 10-lux increments of the IQ-X:

10 to 100 lux

The IQ-X’s new optical system produces a smoother distribution of light on the road than any other headlight. You can set the light to the power that you want, ranging from 10 to 100 lux in 10-lux increments. How does 100 lux translate into lumens? From a cyclist’s perspective, there is no translation. Lumens describes the amount of light produced, whereas lux describes the amount or intensity of light thrown upon a given area at a given distance. From a cyclist’s perspective, lux is a much more meaningful indicator of a light’s usefulness. For more, see this Urban Velo post.

The housing is anodized aluminum and acts as the heat sink for the LED.


The IQ-X has a standing light (like all the B&M lights we carry), as well as daytime running lights. A senso automatically switches to either daytime or nighttime mode. It does not have a blinking mode, and that’s good, because a blinking light this powerful would be extremely annoying, not to mention dangerous, to oncoming traffic. Mounting: compatible with other Busch & Müller headlight mounts. The included mount will work on most bikes. As with other B&M headlights, it includes wiring for a tail light.


The sleek appearance of the IQ-X is also a big step forward for Busch & Mueller.

IQ-X is $146, less expensive than the Luxos B!

We hope B&M will offer a USB port version of the IQ-X that, like the Luxos U, lets you charge phones, cameras, and other devices while you pedal.
