Adjust Your Shimano Nexus Hub

Fritz Rice - Wednesday, February 24, 2010
As you may have guessed, we love some internally geared hubs here at Dutch Bike Co.  We love the smooth shifting, the quiet operation, and the simplicity of use.  From the shop perspective, I enjoy knowing that our bikes are out there being ridden and loved - not worked on.
 
More than any other drivetrain, an 8 speed hub really doesn't require its user to be a "bike person."  An avid cyclist will certainly enjoy it -- as many of you have discovered for yourselves -- but anyone who can push the pedals will benefit equally from the utter simplicity and rock-like durability of this transmission.  Combine the system with a chaincase and in a year of riding you'll probably do no maintenance whatsoever.  You won't even have to wonder whether or not to feel guilty about it.

This brings us to the educational kernel nestled within this husk of a post: adjusting your Shimano Nexus hub.  At this point, you might reasonably grow apprehensive that I'll try to explain planetary gear systems, expose you to exploded views, or start talking about gear inches.  I won't.  Adjusting your hub is a simple and easy procedure that will likely take less than five minutes and won't get your hands very greasy at all.

Step One: Diagnosis
When I teach a repair class, this is typically the subject that receives the strongest emphasis.  Without understanding what's causing the problem, we can't fix it.  Bearing this firmly in mind, we'll quickly check the three main parts of the system: the shifter, the cable, and the cassette joint (I'll explain in a moment).  The cable will come first, because it's the simplest part of the system and -- relatively speaking -- the most vulnerable.  Around three out of four "mis-shifting" or "gear slipping" issues on our bikes have the same simple cause:



Here, the cable housing (the outer sheath) has been tugged out of the shifter, exposing the cable.  It has then caught on the edge of its proper place (the barrel adjuster) and failed to snap back in.  This 1/4" difference leaves the system totally out of whack.  The solution is even simpler than the problem: just nudge the end of the housing back into the barrel adjuster, and the tension already on the cable will do the rest, snapping it back into place.



If all is well so far, check over as much of the shifter cable housing as you can see for damage or kinks that could cause it to drag or bind.

Next, we'll move on to the cassette joint.  This is the little plastic unit on the side of the hub where the cable attaches, and that translates your pull on the cable into the actual gear change in the hub.  If you have a cloth chaincase (any Workcycle, Azor, or Jorg&Olif except Secret Service, Fr8, and Bakfiets) you'll need to open the back end just a little to see the cassette joint.  Unsnap the outside snap, then slide the clip out of the pockets on the inside.



Gently peel the rear section of the chaincase up and forward, and tuck it out of the way.



Now you'll be able to see the gray and black plastic cassette joint, and the little adjustment window with a yellow indicator line.  With a plastic chaincase you'll just be able to flex it inward slightly, and the view will be the same.



Now that you've ruled out problems with the cable, shift into fourth gear (you'll see a dot next to the number to tell you it's special) and check the yellow marks in the small window on the top of the cassette joint: if they line up, you're adjusted properly.  If they don't, then turn the adjuster on the shifter (with a couple of experimental turns to make sure of your direction) until they do.



...And you're done!  You've just done exactly what a good mechanic would have when confronted with Nexus hub "issues," and almost assuredly resolved them.  Take the bike for a quick test ride, and enjoy your perfect shifting.

A Year of Saison

Fritz Rice - Thursday, February 04, 2010
The Saison

It's been almost a year since I built and started flogging the strange hybrid beast that we named the Saison (a saison is a Belgian farmhouse beer style whose wild yeast strains produce a light body but strong earthy flavor).  The idea was to build a bike that could balance the toughness and "fuhgeddaboutit" maintenance interval of one of the Dutch bikes with the speed and acceleration of a modern American commuter.  Strong wheels, a strong frame, internally geared drivetrain, disc brakes, full fenders, and a comfortable riding position were required.  Add a few little extra touches for comfort (carbon bar and 28c Tserv tires) and style (gold Nokon brake housing and gold grips), and I was ready to go.

The Frame
Predictably, I couldn't let myself simply order a frame designed to do exactly what I intended for it (they exist).  Instead, I decided to use the wrong-est frame to build this multi-speed city bike: a single-speed mountain bike.  The Surly 1x1.  And yes, I am perfectly aware of the abject silliness of this premise.  That said, measure the actual radius of a 26" wheel with tire, and a 700c wheel with tire, and you'll find a surprisingly small difference.  Measure the wheel/tire clearance of a 1x1 and you'll run out of measuring tape; you could lose a medium-sized child in the depths of that gigantic rear triangle.  Even with tires half again the size there would be plenty of room for nice beefy fenders, too.
 
So much room

With tough steel tubes, convenient horizontal dropouts, and easily adjustable brake caliper mounts, the Surly would have been a fair bet even if it weren't super cheap.  And deep down, who doesn't want to ride "the thing that should not be"?

The Build
Lace up a wheelset: light-ish rims made for 29'er mountainbikes on a Shimano Alfine hub (the stealth-bomber version of the eight-speed hubs in our Workcycles bikes) and a mostly-matchy front hub, and slap them into the frame.

Lots going on here

Throw on the rest of the parts.  Get a different crankset because the chainstays are so wide that the arms of the compact road crank I'd planned on using wouldn't even come close to clearing...wow.  Bend the fender stays and install spacers to clear the brake calipers.  Install lights on the brake bosses because they're just sitting there doing nothing.  Install the KitchenAid headbadge because this is supposed to be an appliance, right?

The Ride
The first impression of the ride is the quickness: even though it's a big bike with a wide bar, it feels very nimble and responsive.  You just point your shoulders and the bike zips that way.  It's difficult to sufficiently emphasize the nimble feel of the bike and the resulting confidence: the handling is so intuitive that maneuvers that would be nerve-wracking on a more conventional bike just happen naturally and with little fanfare.  The wheels and frame are highly rigid, and even with relatively big tires and the flex of the carbon handlebar the ride isn't Dutchbike-smooth, but it's not punishing.

The cockpit must be perfect

The Alfine hub and shifter snap off quick, positive gear changes with almost no lag or interruption of power transfer.  The disc brakes (Avid BB7 calipers and Shimano XTR levers) offer a surfeit of power and smooth enough modulation to keep it under control, although after putting in the miles on our roller brake-equipped city bikes they feel surprisingly aggressive. 

The Year
Now, after a year of riding around Seattle, up and down stairs, through alleys, around parks and pump tracks, through street brawls and farmer's markets, and over every nasty piece of pavement and road debris I could find, I can actually evaluate the bike.  It has commuted, gone on dates, shopped, and pubcrawled.  It's been taken on countless test rides, and borrowed for extended periods.  Through it all the Saison has required very little of its rider in terms of either maintenance or even basic consideration.  After a few adjustments for break-in, the mechanical systems have functioned as close to flawlessly as any bike I've ridden.  A little chain lube every few weeks, and the occasional stack of batteries for the cheap blinky lights I can't seem to get around to replacing with a sexy generator setup.  It's not quite as impossibly maintenance-free as a Workcycles bike, but it's not too far off.

I can explain the experience of living with this bike best by calling it "enough."  It's tough enough that even through the year of abuse I've barely had to think about it, while remaining light enough to accelerate and climb with pizazz.  It's fast enough to really feel fast, and -- most important of all -- fun enough that I consistently want to ride it.  The best bike is, after all, the one that you ride.

Want one?
With a somewhat less extravagant component selection, you can have one for right around $1700.  We're custom building each one of these for the time being, so even though you're dodging the challenging "experimentation phase" of a project like this you can still have plenty of input on the specifics of your Saison.  An albatross bar, a Brooks B67 saddle and 38mm wide tires for a more "Dutch" feel?  A narrow cut-down riser bar and racy tires for tackling traffic?  A Workcycles Transport-style front cargo carrier?
No problem.  Have a tall, chilly glass of Saison.
Tall glass of fast

Seattle Shop Ride!

Fritz Rice - Thursday, January 21, 2010

Join us Saturday January 30th for an afternoon social ride!  It's been too long since we've left our little cave down here by the boat launch, and too long since we've seen most of you, so come on down.  Ride an Azor, a Workcycles, a bakfiets, a Christiania, a Gazelle, or something American...anything, as long as it's comfortable and fun.

We'll meet at the shop at 4, mill around for a bit, and head out west.  We'll be rolling very slowly, to facilitate talking, kids, laughing, merrymaking, goofing off, and possibly even hijinx!  Eventually we'll reach Golden Gardens, where we'll have some tasty snacks and refreshing drinks, and maybe try to ride a bakfiets on the beach.  When we feel like it, we'll ride back toward Ballard and the shop at a leisurely pace. 

If it's raining, we're still going, and we'll still be raffling off a pair of Clarijs panniers, a Nantucket basket, and a Bikecap saddle cover (pattern to be determined...I promise it won't be the creepy lace one). Five dollar entry for the raffle, and 100% of proceeds go to Haitian earthquake relief.

After that, like-minded adults are invited to join me in cruising toward points east.  Points to include: the Traveler, the George and Dragon, Sinners and Saints, and onward...

The New Year!

David Schmidt - Saturday, January 02, 2010

It's a new year at Dutch Bike Co, with many big changes going on both here in Seattle and out in Chicago.  We're finalizing plans for the interior of our new Seattle shop space on Ballard Avenue, and they're looking great.  Despite the snowy weather and the temptation to hibernate, the boys in Chicago are developing some great ideas for the months to come.  Keep an eye on the blog for posts on all sorts of topics from all of us here at Dutch Bike Co.  We'll have information about upcoming rides, soirees, and maybe even a party or two in the style of the old days!

A few weeks ago our friend Mike Kleven came by and shot some gorgeous video of a Workcycles Opa coming together.  Now for the first time -- unless you've been hanging out in the shop -- you can see the mysterious, alchemical process by which a ragged transatlantic cardboard box is transformed into a beautiful bicycle.

    We hope you enjoyed this little peek into our Seattle shop, and a behind-the-scenes glimpse of the love that goes into each one of these bikes.

Saigon vs. NYC Commuter Vibe

Stephan Schier - Thursday, December 03, 2009

Vietnam is a country of over 85 million inhabitants and 20 million mopeds.  Saigon (Ho Chi Minh City) is a city of over 5 million where many of these machines congest the streets.  If you think your commute is knarly, contrast these two videos below.  The first is taken by our friend and favorite man about the globe, Gregg Bleakney, during a non-rush hour (no kidding) period on Saigon's streets.  The second is our friend Paul Steely White's relatively sedate and well-produced interview through the streets of New York.

How does the vibe of your commute compare?

Stephan Schier - Sunday, October 25, 2009

Chicago 1 Year Anniversary Celebration — Tonight

Join us at our Chicago shop for a Belgian beer tasting tonight, Saturday evening, 6-9 PM, with Don Feinberg and Wendy Littlefield of Vanberg & Dewulf, the Belgian beer experts and founders of Brewery Ommegang, the first Belgian style brewery in the USA. Also, join us during regular hours in the shop,  for a weekend of sales specials on bikes and accessories.

Repair Classes — Seattle

Stephan Schier - Sunday, October 25, 2009

Sun Nov 8th and Sun Nov 15th, 6 - 8 pm, $65 per person

Join Fritz, for two Sunday evenings of two-wheeled wisdom and wit. You'll learn the anatomy of your bicycle, diagnosis of mechanical issues, and maintenance techniques to keep you independent and riding all winter. The first session will cover the anatomy and inner workings of your bikes, troubleshooting and safety checking, and fixing a flat. The second session will focus on fixes and tweaks for your bike that you can do in your garage, without a $400 professional workstand or too many special tools. The material will be tailored to your bikes, so bring them and your questions on both nights, and expect to get your hands dirty.

Chicago Loves its Cyclists

Stephan Schier - Sunday, October 11, 2009

We love that Chicago PD and the DOT have joined forces to produce this safety video which addresses and can appeal to many audiences. Thumbs up to our friend Alex (we miss you) who makes a poignant cameo appearance in the commuter interviews. Now if we could only require cab and truck drivers to watch this video.
