  • The S3X needs the SHORT guide nut

    The S3X needs the SHORT guide nut

    E-Bike Stop told me my S3X has a two year warranty, so I called Sturmey-Archer America, and talked to David, the lone American S/A representative, about my broken axle nut, and how I can’t get the shifting to work with the new, longer nut. I had worried that I broke the hub completely, but it still shifted, even with the broken nut. Turns out it’s just the nut, and David’s mailing me a “short guide nut,” no charge. Super nice.

    this nut goes on a regular 3 speed, not the S3X

    The long “guide nut”* I had gotten as a replacement (the right-side axle nut with the hole for the indicator chain), doesn’t allow the gear adjustment you need. I’m not entirely sure how that could be; it seems like you’d just slacken off the cable, but it sure doesn’t work that way. I think the length of the nut and the cable angle must act like a pulley, and change the amount of travel in the shifter.

    If you need to replace your S3X axle nut, get the Sturmey number and call directly. A shop may not be able to get the short one from the usual channels, and it will most likely cost $5 or so.

    I actually called David back and asked if Sturmey Archer had a quick release for the cable. He thought I meant a quick release for the hub, and said Coombs Cycling Components is going to be showing him an axle quick release system for the S3X at Interbike in a couple weeks. That sounds really cool. The Coombs quick releases look dorky with a QR lever on each side of the axle, but I had a flat the other week with no wrench, so I can see the value.

    As far as a cable quick release, they don’t have anything like that. I’ll probably end up ordering a Bruce Gordon QS2s or Davinci cable splitter for it if I can’t find a SRAM cable release.

     

    * I had no idea this is what they were called. Good to know.

  • On Your Left!

    I used to ride with a bell, and used it every day when my commute crossed the Golden Gate Bridge. Foreign tourists seemed to know what it was, Americans not so much. It really saved me 5 minutes on each crossing, unless I got stuck behind a racer type with no bell.

    After my commute change, I didn’t use it for a few years, and finally took it off the bike. Now I think of bells as foppish affectations, useful mostly as a McGuffin to drive DIY engineers to think up cool mounting points like headset spacers and unused DT shifter bosses.

    To pass stealthily, or announce yourself?

    Most of my life I’ve been a stealthy passer, until I rode with Scott, a friend who has distinct opinions on the subject. Apparently in the Midwest, failure to announce yourself before overtaking another cyclist is a sin, “You will be chased down by a beautiful young woman who is hard as nails and could tear you up in a crit, and she will chew you out for being an unsafe, inconsiderate asshole, and you will take it.”

    I grew up in California, where the sin is failing to glance back before weaving or spitting.

    Anyway, I’m always up for a scientistic experiment, and Scott has some force of personality, so I tried hailing before overtaking, mostly on the busy pathway. People seem to like it. I like it.

    “On your left!”

    “On your left” is more abrupt than I like (being from California and all), and I got a lot of people jinking left before their conscious mind decoded the message. “On your left!” is supposed to be a friendly warning if you have learned what it means. If you haven’t learned the code, it’s a command, and the verb is GO LEFT, like in sports or Drivers’ Ed, when “left” means “wrong way, dummy, go left.” Even if you have learned to ‘instinctively’ drift right when you hear it, it is still an imperative, it just means “GIVE WAY OR HOLD YOUR LINE.” So I don’t like it. I won’t say it,

    “I’m coming up on your left, now.”

    After some experimentation, I settled on saying, “I’m coming up on your left, now.” I try to say it in a way that implies “do what you want, but my intention is to pass you.”

    It gives people time to assess your location in moving 3D stereo; their ears say “there’s someone about 8 feet back, to my left, 6 feet, he’s talking, four feet, he says he’s passing…”

    It explicitly spells out what’s happening: “There’s a man coming up on my left now.”

    It’s conversational and informative. It lets people assess your voice and tone. It’s polite. We’re all on the same side here, gettin’ down the bike path.

    It’s chill. Everyone seemed to react positively and predictably. I’m trying to say it in an aggressive fashion, but the more force I put into it, the sillier it sounds: “I’m coming up on your LEFT NOW!” I just shrug at myself and say “so?”

    Post “paleo” ride. I rode my bike to a big hill, broke my S3X low gear, rode up the hill anyway, and picked a ton of blackberries.

    Yes, I wore the dorky hat the whole time. I really like it.

  • Busted eggbeater spring

    Busted eggbeater spring

    I’ve had these for a long time, and they cracked a couple years ago. The other day they dropped a piece on the road. The down side is the fact that they also welded themselves to the cranks about a year ago! I can still use two sides of this one, and four of the other, but I don’t see these lasting more than three or four more years…

    That’s also the ugliest pedal deck I’ve ever made. It’s a prototype for a mud-shedding deck that might be a hair lighter. It’s stupid.

  • Eat Sleep Ride – bike book review

    Eat Sleep Ride – bike book review

    An English journalist's story of riding the Tour Divide mtb raceEat, Sleep, Ride is English journalist Paul Howard’s account of riding the Tour Divide mountain bike race in 2009.

    I was pleased to see this book at my library, and picked it up. I’ve followed the GDR and Tour Divide off and on for several years, much more than I’ve followed any other bike racing, but had only read Kent Peterson’s Dirt Rag article peoples’ blog posts on it.

    I recommend this book to people who’ve never heard of racing the Great Divide, and to people who follow it year-to-year.

    Paul Howard ups the suspense of whether he will finish the longest mountain bike race in the world, by admitting he had never owned a mountain bike before the trip, and downplaying his cycling experience and fitness.

    The book jacket calls the book “hilarious,” but I don’t hold that against the author. The book industry appears to be in the grip of a Humor Bubble; I’m reading a much funnier book now, which the jacket has to describe as “occasionally hysterical.” I would call Eat, Sleep, Ride “witty in a pleasant English way.”

    Howard brings a sense of history to the land he’s cycling through. The stories, some of which I knew (the cannibal ones), complement the experiences he and his ad hoc group of racers have on the Trail.

    While the Tour Divide is a solo race, riders of similar ability clump together for mutual morale and social support. Sharing physical support would get them disqualified from the race.

    We get to know some of the riders he rides with and encounters, focusing mostly on the underprepared, which is inspiring and interesting, but slightly disengenuous. I’d do a little more research before making my plans for next year’s race. Non-super humans complete the race every year, but I wouldn’t approach it lightly.

    I would have liked to see more on the leaders Matthew Lee, the winner, and Jay and Tracey Petervary in third on a tandem. Since Howard finished second to last, his group’s interaction with the leaders was mostly hearing that they’d passed through a town a week before, or that they were “only” one state ahead.

    I also wanted to know more about Deanna Adams, and her experience in the race. She is the first (and only, so far) finisher of the Tour Divide on a fixed gear bicycle. I ride fixed offroad some, and I’ve been disappointed every year that the fixies had to scratch. I think riding the route on a fixed gear is even harder than it sounds, and this is the category I’m dying to see inaugurated. Unfortunately, Deanna was relegated (disqualified from official standing) for a route error. The next finisher will be referred to as the “first official fixed gear finisher.”

    Recommended.

    I liked this book, and now I want to see the movie “Ride the Divide” that Kent promotes on his blog.

  • Jethro Tool don’t fit Sturmey’s S3X

    Jethro Tool don’t fit Sturmey’s S3X

    This is the series of stuff what don’t fit other stuff; what we call Esoteric Equipment Mismatches, or EEMs. In this episode, we realize that our kick-ass Jethro Tool, which I love except for the gratuitous and stupid bottle opener, does not fit the super-long nuts* on my Sturmey Archer S3X three-speed fixed hub.

    This is me poking at it monkey-style. (“??”) The design of the Jethro Tool is very cool and interesting – the interior void is not one nut-shape all the way through; it’s two nut-shapes perpendicular to each wrench face that intersect in the middle. So it only works on nuts of normal track-nut depth, and the hypertrophied bell housing of the S3X is too deep to mesh with the wrench.

    Ever since I switched tires (I got a sidewall cut riding with Scott and Chloe, and had to boot the tire with a dollar bill, which was the only tire-changing paraphernalia I actually had), I’ve had a heck of a time keeping the darned axle from slipping. I blame the pinner engagement of the anti-rotation washers, but the axle’s been fine for months, so I really don’t know.

    Anyway, Jethro Tool no good for this application; I definitely need the 15mm line wrench I want. The cutout in the wrench would go over the cable, and the six-point engagement would keep from rounding the nut.

    *That’s what Steve Albini said.

    I don’t mind trimming them down, and carving a notch, but the mounting lip isn’t wide enough or deep enough to secure the pad. Too bad.

  • “Max’s” new bike

    “Max’s” new bike

    “Max’s” new bike, originally uploaded by BikeTinker.

    So far, it’s set up for me, while I “iron out the kinks.” This bike is really nice. I want to drop the levers a quarter inch, and run the cables higher on the bars, but it’s pretty well dialed. Dingle setup, 36×14 and 32×18. Flared drops. Flat pedals. I haven’t tried the low gear, but I bought a new ring just for it. Coasting is actually pretty fun!

    I like cassette hubs, and I like disc brakes. And threadless headsets. The two-tone bar wrap is also pleasing me a lot. You’ll see that again in a little bit.

    It’s a Gary Fisher Utopia hybrid my friend Jim (coincidentally a fan of CycloFiend’s bike gallery)  gave me for my 10 year old. I thought (and Max still thinks), “Dude, it’s a grown-up bike!” But at 43cm, it’s the smallest 700c bike I can find, and the same size my LBS recommended for a kid’s first ‘full size’ bike. The only issue is getting the bars low enough, but a short stem, inverted, and the seat slammed all the way, puts the bars and saddle in the same relative position as his Redline Junior.

    I replaced the Metro shock with a rigid Kona Project 2 fork, and got some 42cm Salsa Woodchippers from a friend. The bartape is Newbaum’s cloth tape, from Rivendell.

    So far the kid is sticking with the Redline Junior BMX bike he’s had since he was 5. That works for me, since I haven’t ridden another bike since I set up the bars. Stop me before I put a rack on it!

  • Quill vs. Threadless Stem Adjustability

    Quill vs. Threadless Stem Adjustability

    One of my RBW list compatriots recently took the position that quill stems allow for more and easier bar height adjustment. By the time I finished my rambling rebuttal, my session had timed out, so I put it here instead.

    My friend’s position

    Quill stems allow for far easier (and far more) bar height adjustment, which is why I prefer them.  I also prefer threaded headsets because I can remove the bar & stem from my bike and not have the fork fall out onto the floor.  Threadless headsets were invented by an industry that was lazy and wanted to make more money (by only having to stock a single fork/steerer combo), and were a solution in search of a problem… especially at the beginning.  Sure, now they allow things like CF steerer tubes, but there’s no way in hell I’d run one of them, either.

    I have to disagree

    Except about carbon fiber steerers – there’s nothing sadder-looking than a ‘cross racer trudging out of the mud with a broken-necked Scott, bars dangling free, slung over his shoulder.

    I find it easier to make large changes to bar height and reach with a threadless stem. I now have more (functional) bikes with threadless stems in the garage than quill. If you count my friend’s dumpster bike, it’s a tie. Once I learned that you tighten the star nut and THEN tighten the stem, it’s pretty easy to change height. Add in faceplate stems and you’re 100% ahead of the game when it comes to messing around with your cockpit. Spacers are expensive at $2 each, but takeoff threadless stems seem to just appear. $10? Free? The last quill stem I bought was $20 used, and I’ve never used it.

    Dialing in the bars of the Trek Belleville and the Fisher Utopia has had me fooling around with spacers and stems, one for max height, the other for minimum. The Belleville is done, and the only problem is the ugly black spacers I had. With the black Brooks, they’re starting to look okay, and with black grips, they’d be invisible.

    I never change stem height once I’ve dialed in the bike’s fit. The three main quill-bearing bikes (one just out of service) have had their stem height changed about twice each in the past 7-10 years; all three down a little, and back up to the maximum height. I can’t get any more height out of them without deciding the risks are worth the visible Max Height mark, but since I don’t change height, the ease of downward adjustability isn’t an advantage, and the impossibility of upward adjustability isn’t a disadvantage.

    It took three stems and two bars to dial in the fit on my Quickbeam, but the Fisher can fit me (6’2″), or my kid (4’10”), by moving spacers and swapping stems. A quill stem that could do that would have a hinge in the middle. It would be hideous, and heavy, but the Fisher’s long stem is prettier than any quill stem I’ve ever owned. It’s light, silver and shiny, and doesn’t match the Army Surplus aesthetic of the bike at all.

    I must be particularly difficult tonight

    I find I disagree with the “lazy industry” comment, too. A lazy industry wouldn’t make any changes – it would just price itself out of the market. I don’t feel greedy or lazy, but my time and money are finite resources. I hope that every time I see a way to make a process easier, faster, or less prone to failure, I do it. I hope everyone does.

    38.5 lbs of dogfood, originally uploaded by BikeTinker.

    This was my second grocery run of the day. Taking the car to the second store would have been wasting the 2 Mile Challenge, since the two stores are right next to each other. Go to one by car, shoulda gone to both.

    The saddlebag holds four M6 hex screws. It should be holding some flea medicine, but isn’t.

    The first run of the day was pretty good, too, since it involved a half-rack of beer and 6 bags of chips. Almost everything went into the saddlebag, some in the basket next to the beer, some in a bag on top of the beer case, and then the 6 bags of low mass, high volume Kettle chips in another bag out front.

    cheese, mushrooms, beer and Child FoodThe cheese, mushrooms and beer are mine. Everything else is for the child. Even the coffee.

  • Liz’s Raleigh Makeover

    Liz’s Raleigh Makeover

    This was a little makeover project I did a while ago for my great friend Liz.

    The tires are skinny 25s, but they rolled pretty well for me even at, what, 5 stone more than Liz? And… they’re all that would fit with fenders. The real clearance issue was the pinchbolt on the front derailler, if you can believe it.

    Elizabeths classic road bike, now a Portland cruiser - with a broken stem clamp

    Elizabeth worked on the California AIDS Ride, and trained and rode thousands of miles on this bike, a hand-me-down from her father. It hung in her garage for years after, until she realized I was some kind of bike nerd, and would LOVE to tinker with her bike. Our friend Mark provided the fenders and some bits, and we were off to the races!

    I see from the picture I’m a dramatic shortener of cable housing, and I think all bikes should have fenders. I thought this even when I lived in California. There are still AIDS ride sticker mojo (stars signed by sponsors), and most of the components are original, since we didn’t have the funds to drop on gearing or 650B wheels (or 590A, even).

    You might have wondered what’s up with the hipsteriffic bars. “Yeah, what’s wrong with those bars?!” They’re Albatross bars from Rivendell, rotated all the way around.

    Funny story.

    Max and I went up to Portland to ride around with Liz on her new whip (her on hers, us on our old regular ones). She warned us, “There’s some massive Portland bike ride that day. We want to make sure to miss THAT!” We were late getting to her house because I-5 was closed down for the bike ride, and we had to sort of circle her entire neighborhood, honing in by degrees as we encountered blocked off streets and streams of cyclists at every turn.

    Anyway, “Whew! Frickin’ bikers! Now we can go ride our bikes!” Getting ready to go, I noticed the bars were loose in the stem. That’s no good! Tighten tighten, SNAP! The aluminum clamp cracked right off. I believe it was a case of a 25.4 bar in a 26.0 stem. Huh. “That dog won’t hunt!” We went to a McMenamin’s, instead.

    That was many months ago, and I’ve had a replacement stem in my bin for her for almost that long. I should mail it to her, so she can replace it herself, but I think it’s another 26.0.

  • quickbeam s3x update

    quickbeam ride with the dog, originally uploaded by BikeTinker.

    The dog and I went out for a steep offroad knockabout with the S3X hub.
    I pulled the splined 15t cog off, and substituted a Surly 17/21 dingle cog. I intended to use both gears, but ended up sticking with the 42 tooth ring and the 17 tooth cog.

    I had some slipping in the lowest gear that seemed to be related to shifter slippage. When it happened, I noticed the cable was very slack in the high gear. I tightened up the cable (a simple twist of the connecting rod), and the problem seemed to disappear.

    More research is in order.
