Here’s Mitch on Jason (Red Fox Bakery)’s boneshaker. He seems to be a natural.

I rode it. These things are really frickin’ hard to ride. When I got out in the street I knew I’d done something wrong. The thing wanted to throw itself under a car. I stayed in my lane through sheer force of refusing-to-die. There’s an anti-intuitive steering thing going on that I can’t quite figure out. It’s a little bit like a bad dream where you’re running but can’t get away.

You look at the oncoming car, but turning away from it makes you head toward it! Agh! Maybe the weirdness is related to the vertical steering axis, or the fact that you’re pedaling force is connected directly to your steering… Don’t know. Hated it. I had to jump off in the street and walk it back.

Jason told me that Red Fox does a Friday night pizza party at the Saturday market cob oven. Free get-together, and we’re talking about having a bicycle show there.

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.

Kevin Dwyer’s bamboo mixte

Kevin Dwyer of Salt Lake City designed and built this amazing bamboo and carbon mixter. He sent me the pictures a while ago, and I went looking for them tonight to show them off.

He says, “Attached are a couple of photos of my last frame.  The handlebar and leather grips are also custom by me.  The frame has structural carbon inlays on the down and seat tubes in a sweetpea vine fashion. The dual top tube bridge is reinforced with tarantula web (no shit!) composite.”real tarantula web in the carbon“The inlays are “keyed” into the bamboo creating a superstructure, dramatically stiffening the bamboo.  Also, they are cross laminated with the carbon fiber at the joints.  They vary in depth, fiber orientation, length and width depending on application, with some, but not most, going all the way through. The inlays were sketched/transferred  to the surface then carved out with a variety of tools (mostly power) and methods.”

Kevin Dwyer made the bar and grips, tooEven aside from being handmade and innovative, it’s a nicely built-up mixte with a unique look. Caliper front, disc rear with an internal gear hub, it might take you a minute to register that it’s made out of bamboo.

Dogfood bike delivery.

 

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

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.

Sugru?

This stuff looks cool. I saw Sugru mentioned on Instructables, and had to check it out. I really like the handmade look of the Sugru website. Very low-stress website.

illustrations of various uses for Sugru, from their site.Sugru is moldable silicone that sticks to metal, leather, ceramics and glass, and cures into flexible, weatherproof silicone. It’s designed to help you fix broken things, or hack your stuff to make it better. People make stamps with it, too! It’s an open-ended substance, and I think the developers are interested in new uses. They give 5 packs away to the “Hack of the Month.”

Sugru can be used to add grip to slippery things. You can texture it. It sticks to itself and lots of other things. You can mold new shapes onto things, like grips or bumpers. You can plug holes, and repair cracks. You can customize the fit of shoes. It insulates, so you can use it on hot and cold things that you need to touch. It’s silicone, so it withstands extreme temperatures.

Bike uses for Sugru?

Has anyone used Sugru for bicycle repairs or hacks? I saw in a video one guy was putting it on thumbshifters. I could see putting a thin layer on metal brake levers to keep them from freezing the bejeezus out of your fingers.

Aha. It looks like a Friend of Sugru used it to create mounts for his bike bell, cyclometer, and rear blinkie.  Maybe also patching a hole in a fender (I have a couple of those, from moving the stays).  I really like the location of his bell – right on top of his mtb brake lever mount.

Another person fixed what looks like a Regal saddle with Sugru.

Get Sugru?

You can buy it from Sugru.com. | And you can make it yourself out of pure silicone and corn starch.

 

Belleville update

Baskets, cranks and saddle dialed in on the Trek BellevilleThe Belleville turned out to be a success! It’s dialed in for fit, and function, with a couple of “form” tradeoffs*. Angelina says it’s heavier than the old bike, but “feels sturdier,” and she loves the dynamo lights. It’s a huge relief not to worry about batteries, or turning the light on. I’ve seen her rolling along at dusk, too, and they’re pretty visible.

Goodwill basket on the Belleville's front rackDespite all the goodness, Angelina kept riding her old bike, because it had the baskets. She uses the bike as transportation, so she needs to bring things home. I moved the Wald folding baskets to the new bike, which was good, but she didn’t like having to bungie things onto the front rack. I balked at moving the front basket, though, because it didn’t fit the rack or the bike’s aesthetic. After she threatened to wire the old basket on with whatever twine or baling wire she could find, I went to Goodwill, determined to get something basket-like. Wicker picnic baskets (hmm, not bad), heavy storage basket, suitcase… and this. It looks like it might have had a laundry-room or dishwasher function, but it fits the rack almost exactly, and is cut down in back to go right under the bar! Perfect. Plenty of room for a half rack of beer. It even had wire “ears” on the bottom I used to attach it to the rack , through the magic of ‘bending.’ One broke, so a single hoseclamp replaced it.

Repaired Brooks saddle on the BellevilleThe stock saddle turned out to be really comfortable, but not at first. I flipped the saddle clamp around, so the post is in front of the clamp, instead of behind. This gives more setback, but also more leverage on the saddle to knock it out of angle, so you have to tighten it like mad. I’m cautious doing that, though, since I snapped the bolt on the Brooks 2-rail clamp (the Brooks bolt had two weak, flat sections, which is really stupid), and had to replace it with a much sturdier Chinese part.

I was a little worried about installing the repaired Brooks, since the Trek Eco saddle has been so comfortable. But I did the work, and it’s a great seat, and I can always put the Eco seat back on. This Brooks has the same flipped clamp, which gives 1/2″ more setback, which surprised me.

Cork repair to the Eco handgripThe grips are hard plastic, held on with screw-clamp ends, and have to be rotated on the bars so the indentations to line up naturally with the hand. One almost came off in an intersection, and the cap part disappeared, so I replaced it with a cork. And tightened up the little allen bolt. I may leave the Steyr out in the sun, so I can slide the old grips off and use them on the Belleville.

Other tweaks.

I bumped up the handlebar height about an inch, with spacers. Chris King red, brown and blue spacers would be dynamite, but black goes with everything.

The cranks are 175mm Ritcheys she’s been riding for a few years on her old bike, and she said they made a HUGE difference in comfort. The tread is also much narrower, and the left arm almost hits the kickstand. I think the chainring’s the same size. The white pedals are borrowed from another Austrian-built 3-speed my friend asked me to fix up for him. All I’ve done so far is pull the front wheel off, spin it, wince, and put it down. And steal the pedals.

It looks like I need to get some zip ties to corral that wild shifter cable. There are brazed-on lugs for the zip-ties, which is pretty cool.

I took these pictures with my new camera and old, old lens. Some are nicely focused, some not. More practice!

*The baskets are dumpy, but the cranks and (stolen) pedals are prettier.

New Camera

I’ve been spending my tinkering time playing with my new camera, a Sony Nex 3.

The tinkery bit comes from the two adapters I bought for classic lenses. I’ve been using my Exakta lenses for about a week, and the Canon adapter came yesterday. This is what I’ve actually been spending my time on: researching lens options for the Nex. Idiotic.

I’m going to put the finishing touches on Angelina’s Belleville (old saddle, maybe old grips), and use the new camera to take the photies. In the meantime, I went to a parade and took pictures of people with my 135mm Angenieux (a 203mm lens on the Nex) . Totally unbikerelated, but I did go for a mountain bike ride beforehand.

Brooks Saddle sculpture – after Picasso

Here’s my take on Picasso’s “Toro” bronze sculpture, using the left over pieces from the repair of Angelina’s B72 saddle. I glued the leather back onto the broken frame (Gorilla Glue!), and squeezed a beautifully patinated steel drop bar between the cantle and the rails.

It’s maybe a bit more of a Bighorn Sheep than a bull, but I’m more of an American than a Spaniard.

Little Trailer Guy

I’m a huge fan of this. I love the shot with the dog, of course, but I’m most impressed with the perfect fit of the dog carrier in the trailer frame. It makes the whole rig look custom.
The Baggins bar sack on the trailer is a beautiful touch.

I wish my dog could fit in that rig. We’d ride out to the logging roads, I’d lock up the trailer and then she could run. Life would be perfect and the birds would sing.
