DIY Leashless Umbilicals

I sold off my old ice tools for newer ones. I got Petzl Quarks as I wanted a tool that had leashes but could go leashless and I found I enjoyed the swing better than other tools on the market that fit the bill. I had not climbed leashless, so I wanted to start on them with leashes. That idea didn't last as the first time I went out this season I kept the leashes in my pack. I found climbing without leashes to be such a release. Now ice climbing is more like rock climbing. I can shake out easily and placing screws is just as easy. Even yesterday while climbing it made some mixed type moves much easier to do where I used a branch as a hold on a climb. This is not easily doable with leashes if only for the mental concept of the tool being attached to you person.

So after my first true leashless experience back in November I knew I needed to make umbilicals for my tools in the event I do a multi pitch route with them. I started with the information on AAI's blog to make my own.

Their version calls for a swivel, which I don't feel I need. I am not doing anything fancy like switching and matching at this point to make that a needed part of the umbilical. Removing the swivel keeps weight and price down when making your own too, so that was also a concern of mine. Speaking of which, it was about five dollars for the 1/2" tubular webbing and 1/8" shock cord both in twelve foot lengths. Adding a swivel probably jacks the price up to $10. (Still much cheaper than a $45 one from Black Diamond.) I followed the instructions they had and used bailing wire to snake the shock cord through the webbing which made it easy.


However, the instructions that are provided incorporate the length of the swivel into the system. Upon completing mine I found it too short for the way I wished to use it. So I added a loop of webbing to extend it and hopefully use it to girth hitch to my harness. It turned out to be still a touch short, so I now clip my extension loop onto a biner on my harness. If you are planning on doing this yourself, test often. I think the only sure test before cutting is to try it on with a harness and take some swings. Make sure to take a few to the side as well. If you are tall like me and don't plan on adding the swivel, the full 12' would be a good starting point. Since I have Quarks, I made small loops of 4mm cord to clip climbing carabiners into to loops.


Having climbed on the umbilicals once, I can say most of the time I do not notice they are there. However, there were a few occasions where they hooked on screw heads or icicles. But I'd believe with practice that those events should diminish.

Iron Goat Trail ..

Hot weather and mixed signals caused me to be sans partner again. Originally I was pretty bummed, but really enjoyed my final choice of destination or, conveyance.

I looked through a mountain bike guide and decided to get some low impact exercise. I decided on the Iron Goat Trail as it is in the south side of the valley and should be fairly shady. It is a rail trail and used to be part of the Milwaukee Railroad. It is also part of the larger John Wayne Pioneer Trail, which stretches most of the way across the main portion of the state to Idaho. I was also excited to ride my bike through the Snoqualmie Tunnel. However, since this was a plan hatched before going to bed the night before, I had no idea the tunnel was closed.

The tunnel
I parked for the trail off Exit 38 of I-90, but could have taken the western terminus near Rattlesnake Lake. This is where I saw the sign in the parking lot stating the tunnel was closed. Mostly it meant I did not have to worry about a headlamp, and it was cutting about five miles round trip off my excursion.

Since it was unclear where to access the trail, I accidentally rode up the pedestrian foot trail before locating the rail trail and heading east. I immediately starting riding by the Exit 38 crags where people were climbing (and blocking the trail.) The route is deceptively flat/uphill. It has to do with the maximum angle a trail can climb, which isn't that steep. The trail looks flat, but I had to constantly grind my way uphill. A much different workout than a steep hill where you can alternate between standing and sitting. My speed was twice as fast, and cadence maybe five times faster. Sections with deeper gravel really took extra effort. I paused at the halfway uphill point to catch my breath a bit. It was also nice not to be sitting, as my mountain bike saddle is not meant for thirty miles of continuous sitting.

I rode along occasionally standing to give my backside a rest while passing hikers and other bikers. I also passed numerous trail heads that I have been to before while hiking or climbing. In a little over an hour, I reached the closed tunnel. A few pics were snapped, I snacked a bit, and then it was time to enjoy the downhill. There is a nice picnic area there that offers views of Snoqualmie Pass peaks.

While I did not have to continuously pedal for the downhill, it was not steep enough to coast the 14 miles. Of course, to make things more difficult there was a headwind in many locations on the return trip. More wooded areas blocked the wind, but on the trestles, it slowed me down a touch. I was back at the car over two hours after I left.

This was a good ride and fairly mellow if you discount the fact that it is uphill the whole way east. Hopefully the state will find the money to make the tunnels safe so one could ride to Idaho if they wanted. The fourteen mile section I was on had some ample camp sites, although I'd imagine I wouldn't need one until the other side of the pass.

Long weekend break

Hi there--Bonjour! I am off for a looong weekend in Central Europe (Geneve)—looking forward to enjoying the charming villages, learning a new culture and tasting the local fares. All I am wishing is good weather and I so hope the forecast will change because I can’t change my flight and hotel booking now.

3 Wheels and a Box: the Christiania Cargo Trike

If you've been hoping for a change of pace from the recurring roadcycling theme, your wish is granted. Yesterday I had a visit from Will of BoxCycles - an importer of European utility bicycles whose warehouse is not far from Boston. The purpose of the visit was to drop off one of these - but more on that later! In the meantime, he was also delivering thisChristiania cargo trike to someone local, and I had the opportunity to try it.

Christiania Bikes have been around since 1976, initially as a small workshop in the Freetown Christianianeighbourhood of Copenhagen, Denmark. If you do not already know the history of this unusual neighbourhood, it's worth looking into - very interesting stuff. In addition to Christiania bikes, the modern incarnation of Pedersen began there as well. Having over time expanded, Christiania now has a factory on Bornholm Island. Their cycles remain manufactured, finished and assembled by hand - the most popular model being the cargo trike shown here.



Though I occasionally see cargo trikes both in Europe and in the US, this is the first time I've examined one so closely. The Christianiais aheavy-duty welded aluminum frame with three 24" wheels: two in front and one in rear. The cargo box is positioned between the front wheels and the cyclist steers with it when turning. The box is plywood, and there are several models available in different widths and lengths. This trike is 82" long and 34" wide, weighing 75lb when empty. It accommodates 100kg (220.5lb) of weight can can be used for anything from hauling cargo to transporting children.



Inside the box is a bench with padded seat cushions and two sets of seatbelts. Given the weight capacity, this trike can easily fit several children, or even an adult or two.



Seatbelt attachment points on the back of the box.



The handlebars are not really handlebars at all, but more like a pram or shopping cart handle.



The lefthand side is set up with a front brake lever, parking brake and bell. A parking brake is necessary with a cargo trike; without one it will roll down even the tiniest inclines.



The righthand side is set up with a gear shifter. The trikes are available as either 7 or 8 speeds.



Shimanocoaster brake hub, clear chainguard, massive cranks and non-slip pedals.



The chainguard provides good coverage, though it is not a full chaincase.



The front wheels are set up with disk brakes, which are activated by the hand lever. Tires areSchwalbeBig Apple.



Rear reflectors are affixed to the fenders of each wheel. A dynamo lighting package is available with his model, using a bottle generator on the rear wheel (you can see the attachment arm for it here).



The stock saddle is a plushy vinyl SelleSan Remo.



I rode the trike briefly and clumsily, so I better use the pictures I took of Will to show you how it works. To operate the trike, you basically need to point the box, using that one long handle, in the direction you need to go. This sounds simple enough, but if you've never ridden this kind of trike before it is completely counter-intuitive. The other thing that takes getting used to is that when turning, the box pivots on its axel and becomes parallel to the cyclist - not unlike a swing bike!



Watch this: Here is the trike going straight.



And here is what happens when turning. Crazy!



Those who own one of these trikes say it takes about a day to get the hang of the steering, but that once you do it becomes second nature. While I have no experience with other trikes, there is a nice test ride report on Suburban Bike Mama where she compares the Christianiato her own Sorte Jernhest. I've also seen a couple of Christianiasaround Boston at this point, and the owners seem pretty adept at steering.

If we continue to live without a car (which at this point seems likely), it is possible that I may want to get some massive cargo hauling contraption in the future, which is why I was curious to test ride one of these. One thing that surprised me about the unloadedChristianiais how light it felt. I expected the trike itself to be heavy and clunky, but it has an almost airy feel to it without cargo. It rolls easily, including up the mild incline of my street. Once it is filled with 100lbs of stuff I am sure the handling will be different, but it is nice to know how the trike behaves on its own as well. Making turns felt wild and tippy, but also a lot of fun. Since others are able to grasp it in a day, I am sure I would as well. My one source of ambivalence toward the Christiania, is that it seems designed specifically to transport children, which is not what I would need a cargo bike for. It's not only the benches (which I am sure are optional), but also that long handle and something about the general look that, to me at least, makes it resemble a giant pram. I can just imagine using this trike to carry equipment and being constantly asked how many kids I have. Having said that, I think that most people considering a cargo trike like this do in fact plan to transport children, which would make what I am describing a good thing. If drivers see you on the road and think "baby carriage!" they will probably be more careful and will give you more room.

Front loaded box cycles - be they two wheeled bakfietsor cargo trikes -are a radically different experience than riding a standard bicycle, but they also offer a radically different degree of utility. As more people are looking at transportation cycling as a normal and viable option, cargo bikes of all sorts are becoming more popular and I love seeing them on the streets. Maybe a couple of years from now, I will be riding one to the hardware store and writing about it here.

Update from GRIP

I'm behind with posting but with good reason. Yesterday's classes were Intense. Yes, with a capital "I" and they were also Interesting, Informative and Mentally Exhausting.



I was up late last night (as were most other classmates in the Advanced Research Methods with Tom Jones). In addition to a full day of classes yesterday (please go read Chris Staats' post about yesterday's classes and wish him a belated happy Anniversary while you're there) we had a homework assignment. We had no idea how hard it was going to be, but that look of glee on Dr. Jones' face when he gave us the 8-page handout should have been a clue!



I do enjoy a challenge but this was something else. There were abstracts of 16 tax lists, 3 census records, 12 deeds, 4 wills, 2 guardian records, 2 marriage records, and a Revolutionary War Pension affidavit that we had to review, analyze, and try to determine the father of a man from 5 other men with the same surname!



But before tackling the homework I decided to attend the presentation by Rick Sayre on Pennsylvania Research, which was good but he quite a bit of time on Pittsburgh records. I would have liked to have heard more about statewide records.



After returning from the presentation, I spent 4 hours working on the homework assignment. At that point, I still hadn't reached a conclusion but my head was hurting and my eyes were burning so I turned in for the night. Less than half an hour later an idea popped into my dull brain and I "had" to get up and work on the problem before I lost my train of thought. Yes, the answer had come to me. A short time later I was back in bed sound asleep. I didn't even hear the storm that came through that many were talking about today.



I worked on the problem for another hour (consolidating my thoughts and trying to come up with some idea of how to "defend" my conclusion) before heading off to class. Dr. Jones went through the list of possible fathers, one at a time, asking those who thought it was a particular man to raise their hand. When he got to "William" the hands of about 2/3 of the class shot up. I had a sinking feeling in my stomach since he wasn't my choice! When the name of the one I had chosen came up only 3 of us raised our hands.



A minute or so later, Dr. Jones announced that there were 3 "A" students in the class! I had gotten it right! To say that I was ecstatic is an understatement... So, I'm giving myself a little pat on the back and tooting my own horn a bit too. I must say, it felt awesome.



It's been another full exhausting and enlightening day, and we're almost caught up with the syllabus. Tomorrow is the last day with only half a day of classes. It's been an amazing experience and I am so glad that I was able to come.



I'm sure that Chris will be blogging about today's classes as will classmates Shelley Bishop at A Sense of Family and Christy Webb at the Geeky Texan. Also Denise Levenick, the Family Curator, has also been blogging about the Intermediate class she is taking.



This will likely be the last post from GRIP... I've got to get busy on the homework for tomorrow...
