Gadget Lab Fixed-Gear Update: Donor Bike Acquired

masi-1

Finally, after almost five months of searching (and kind of cheating by actually buying one ready-made), we’ve found a donor bike for the Gadget Lab fixed-gear conversion. It’s an old Massi Master road bike, with Italian Gara Cro-Mo steel tubing and forks. The groupset, or brakes and gears and everything else that moves, is Shimano 105 ,which has the gear-shifters built into the brake levers (that threw me at first).

As you can see, the frame is a rather lovely metallic purple color and the style of the graphics plus a little googling makes me think that the bike is from the 1980s. Judging by the comments we get on any of our bike posts, I’m sure y’all can do a much better job of identification.

The wheels have the matching Shimano hub with Wolber rims, and they look so nice that it seems a shame to swap them out. But swapped they will be, as however slick this looks as a road bike, it was bought to be sacrificed.

There’s one problem, and the eagle-eyed amongst you will have spotted it already. The frame has vertical dropouts, meaning chain tension can’t be adjusted without either luck or an ugly tensioner. I will be using a half-link BMX chain, so fingers crossed — but the frame is so nice I couldn’t help but buy it.

The conversion will take place over the next few days, replacing wheels, chain, seat (it’s a nice seat, but plastic saddles in the summer are hell) and stripping off all the extra metalwear.

I need a few tips. First, the rear brake cable runs trough the top tube, entering and exiting through lugged holes. I’m keeping all the parts I strip, in case I decide to change back in the future, but this looks impossible to re-thread. What kind of voodoo is needed to do it?

Also, tips on chain-tensioners are welcome. I’m going to do my best to match up gear ratios and chain to avoid adding one, but otherwise what is the smoothest, quietest way to go?

I think everything else will be pretty easy, between a lifetime of tinkering and all the good advice the Gadget Lab readers have lent over this series of posts. First, though, I have a puncture to fix: The guy I bought it from hadn’t put enough air in the tires and I got a pinch-flat.

The Limousine, An Unrideable Stretch-Bike

Limousine bike

This is “Limousine”, a stretch-bicyle from Wouter Mijland. It is completely impractical, the handlebars put out of the riders reach by the iron-pipe extensions, and even if you were Reed Richards that huge triangle would surely flex and buck like an unmanned fire-hose.

But I love it. Perhaps it is the ridiculous inclusion of the everyday practicalities like lights and a pump on such an outlandish machine, or maybe it is the clean lines and seamless construction. Either way, it actually starts to make tall-bikes look like sensible transport solutions.

You can’t buy it either. The description, “‘Limousine’, 2008, bycicle [sic], iron pipes”, combined with the Flash site, telegraph that this is art. And who would want it anyway when you could hop onto Mijland’s other cycle project, a bike/shopping cart hybrid (below)?

Bullitt Bike is Cool, Cargo-Carrying Cruiser

milkplus_festtool

This is the bike Steve McQueen would ride, if he was riding a cargo-bike from a San Francisco farmers market in pursuit of two kids on BMXs who had stolen his organic Porterhouse steaks and cigarettes. If McQueen wanted to catch these ne’er-do-wells lickety-split, and still make it home with a full load of groceries after launching himself off the crests of the SF hills, he do it on the Bullitt, from Danish bike-meisters Larry Vs. Harry.

The Bullitt puts the sport in “sport utility”. It is longer than a regular bike of course (245cm) but not much wider (47cm) or heavier (24kg). This is thanks to the oversized aluminum tubing, which is stiff enough to stop you wallowing with a full load and light enough that you could actually get up some of those crazy San Fran slopes.

There are several models, and aside from the bright colors the differences are mostly in brake and gear configurations: you can opt for a hydraulic front-brake (a good idea) and choose derailleurs or a 7-speed SRAM hub (pick this one. It’s no fun trying to push off from the lights in to high a gear, and hub gears shift when you are stationary). This bike looks like a lot of fun, and you can even take the dog for a ride.

Prices start at €1800 ($2,570), and includes a lock.

Fuseproject commissioned by the City of New York to make bike helmets look less bad

In cities like New York, where bikers ride right alongside heavy traffic, bike helmets are a must. Trouble is, apparently plenty of riders don’t like wearing them because of vanity — most bike helmets aren’t exactly attractive, if you haven’t noticed. Well, the City of New York’s commissioned Projectfuse helmets — that combine safety with an attempt at decent stylings. The helmets feature a two-fold design, with an inner protective polystyrene, which is then covered with a customizable soft fabric that attaches with straps. No, you cannot buy them yet, and we don’t know anything about pricing or availability yet, but we do know that you can score one for free — yes, free — at various events around the city. Let us know if you snag one!

NYC Giving Away Cool Bike Helmets

nychelmet

There’s probably one thing that stops adoption of bicycle helmets more than anything else, and that’s the fact that they all look so dorky. The standard road-style noggin-covers make your head look like some ridged Klingon nightmare, and the slightly cooler-looking BMX lids are still rather unwieldy, and will muss your hair to boot.

Some of us just buy the best-looking helmet we can. Others would rather present their fragile melon to the asphalt in its raw, naked form. In New York, there is a third way. The Fuseproject is an attempt to make headwear look good. Inside is a skate-style helmet, and outside you can cover up with one of many “caps”. They do share a problem with other BMX-type helmets which have such little ventilation that they’ll boil your brain in anything but deepest winter.

These are not on sale yet, but are being handed out by the City at various NYC community events. Good luck!

Giant Bowery FMX: The Fixie That Thinks It’s a BMX

picture-112

Watching what some people can do on a fixed-gear bike amazes me, but it always seemed a little odd that people would choose a bike built for track racing to pop their tricks. Surely there already exists a perfect machine for throwing around half-pipes and streets, its design honed over decades: the BMX.

Giant seems to agree, and it’s Bowery FMX is a hybrid of its successful budget fixed-gear and a BMX. Even the name is a mashup. The frame is made from oversized aluminum tubing, the fork from tough cro-mo steel and the seat is distinctly BMX in style. There’s even a top-tube pad for kickin’ it BMX Bandits style, and brakes, for those people who don’t like to die in traffic.

The price for this schizophrenic ride? $750.

Osloh Pants: Utility Wear for Cool Cyclists

hipster-pants

The Osloh Pants from Brooklyn, NYC, address a need which doesn’t really exist, but at least thay do it in style. Available as regular stretchy pants or as (stretchy) jeans, the pants are designed for fixed-gear riders. Sure, you could wear them to ride any bike, but the two-strap cinching on the right leg keeps the oily dirt from the exposed chain away from your trouser leg and the tabs above the rear pocket fit a Kryptonite Evo Mini perfectly (and allow it to drag the waistband down for the trademark hipster-crack).

Inside there are a few other tricks. The crotch is padded and incorporates a chamois, the waistband can be tightened, there’s a cellphone pocket on the side and a key pocket hidden within.

$100 to $130 depending on fabric (the denim costs more), or about the same price as a pair of skinny Levi’s. Also, if you read the label wrong, they appear to be “Door Resistant” (it turns out to be just “Odor Resistant” in all-caps).

Test Rides: Virtual Bike Fitting Room in Your iPhone

testrides

Test Rides is a “virtual bike fitting room”, an iPhone application which puts you inside the computer and measures you up for the perfect-sized bicycle. Think of it s a little like Tron, but with real bikes instead of light-cycles. And math instead of impossibly exciting CG death-races.

First up, you snap a picture of yourself sitting down. This needs to be taken from the side, with arms and legs visible — you might get a friend to help. You then place crosshairs over your joints: elbows, ankles, knees and so on. With this information, Test Rides will go ahead and tell you what size and shape of bike you need, from the length of the forks to the drop of the bottom bracket.

You’ll need to do some work. While the app has a few bikes already input, these are really just for demonstration purposes. You’ll need to pore over the actual geometry measurements of your prospective steeds to determine the right machine, which makes Test Rides more of a helpful number cruncher than a true “fitting room”.

The good news is that detailed geometry specs are available online for many better bikes. The bad news is that they aren’t always measured in the same way so you’ll have to do some sleuthing. Also, while $5 isn’t much, this is a rather specialized and possibly single-use application. Still, if that $5 saves you from buying an ill-fitting bicycle, it might just be worth it.

Camper Bike: A Home On Three Wheels

5_camperbikeride21

Kevin Cyr’s Camper Bike is “a functioning sculptural piece”, designed to be shown off and to star in Kevin’s own paintings and drawings rather than to actually be slept in, but we love it nonetheless.

The bike, actually modified into a tricycle, carries its home on its back, just like a snail and probably not much faster. But it does solve a problem of bike touring: Where do you sleep? In the old, pre Camper Bike world, you could either carry a tent, sleep under the stars or just bring along a credit card and stay in hotels. Now you can sleep in a real bed, and maybe even use a real toilet.

We say maybe as we’re not sure what’s inside. We suspect that this is, just like the snail’s home, nothing more than a shell. After all, a bed up top in the long section would render the rickety rickshaw dangerously top-heavy, especially on uneven ground. This doesn’t stop us from wanting one, though, if only to freak out other road users. And remember: Always engage the parking brake before sleeping.

Hands-On With the Sram Torpedo Hub

pr_swobo2_fRiding a fixie is fun, but sometimes you want to switch from fixed-gear to freewheel so you can lay back and take it easy. For example, instead of windmilling your pedals desperately fast on a downhill, you might prefer to coast.

The traditional solution to this dilemma has been a flip-flop hub, which is fixed on one side and freewheel on the other. Whenever you want to switch, you just unbolt the wheel, turn it around, and bolt it back on. It’s not hard, especially if you have a lightweight wrench in your messenger bag (or if you’re using a quick-release hub skewer), but you do run the risk of getting chain grease and road dirt on your hands.

With the Sram Torpedo, all you need is a narrow standard screwdriver. Poke it in the hole on the cog side of the hub, turn the screw inside a few revolutions, and the hub locks down. Turn it the other direction, and you’re back to freewheeling.

It’s brilliantly convenient. Unfortunately, the beauty of the concept is marred by two niggling problems. One is that in fixed-gear mode, the hub has a few degrees of free play. In other words, when you start pedaling or begin slowing down, your pedals will move an inch or two before the hub actually engages. Add in the slack from a loose chain and the backlash is even greater. In practice this isn’t a real problem, but it’s slightly disconcerting and may lead you to distrust the hub a little. It also makes trackstands a bit harder.

The second downside — and this isn’t Sram’s fault — is that because you’re using the same sprocket in both modes, there’s no change to your gear ratio. Many people who have flip-flop hubs on their bikes put a slightly larger sprocket on the freewheel side, making pedaling easier if you’re going uphill (or headed home after a long, tiring ride). You don’t have that option with the Torpedo.

You do need to carry a long, skinny, standard screwdriver — probably not something that’s not already in your normal bike repair kit. But for switching between hub styles, the Torpedo’s convenience is impressive.
