Making Sense of Handling Characteristics

Test Riding the Soma Smoothie
"Hey, so how does it ride?"



It seems like such a simple question. But the more I learn about bikes, the less certain I am how to answer it.As cyclists, our experience expands as we ride more, and as we try different bikes. And our vocabulary expands as we talk to other cyclists, bike mechanics, salespersons; as we read cycling literature, including myriads of bicycle reviews in magazines and blogs.One thing I notice is that while there are default terms used to describe bicycle handling characteristics, these terms are weakly defined - with different persons using them in different contexts.In particular, it fascinates me to navigate descriptions of bicycle stability versus twitchiness.



In reviews I will often read that a stable bicycle "tracks well" or "rides like it's on rails."As I understand this notion, it means that the bike holds its line of travel on its own accord, without the rider having to constantly micro-correct the steering. This is generally considered to be a good thing. But can it be too good? For me, when experienced at high speeds the feeling of the bike being on rails can also make it resistant to turning. And what about going around sudden obstacles? If the bike tracks so well that it resists changing course, would this not present a problem when encountering an unexpected pothole, or when the rider in front of us swerves?



The concept of twitchiness is not so simple either. There seem to be different kinds, and I can think of at least three: There is the "squirrely" twitchiness of a racing bike that makes it hard to controlat slow speeds.This is not to be confused with the twitchiness of low trail - a very different kind of feeling, that gives the rider a more active role in the bicycle's line of travel. There is also the twitchiness associated with a "light front end," regardless of geometry.



Stability can vary with speed. On some bikes there seems to be a linear relationship: The bike will start out twitchy when slow, stabilise at moderate speeds, and "ride like it's on rails" when going especially fast. The faster you go, the more stable it is. Other bikes will be stable at slow speeds and track exceptionally well at moderate speeds, but then level out or even ease up at fast speeds. Other bikes still will handle more or less the same regardless of how fast you ride them.



Whether a bike is described as stable or twitchy, it is hard to know what that means without additional detail, which is not always available. What I wonder is, have there been efforts to maybe create a guideline for both reading and providing descriptions of how a bicycle rides? Without context and well defined terminology, it seems that anything goes and we can easily misunderstand each other's impressions of handling characteristics.

Day Trip to Gulfport, FL


Today I took a day trip over to Gulfport. I was supposed to go last week, but ended up being too sick to go so I was glad I felt well enough this week to make it. I would have been very disappointed if I had not been able to because I was going to see some of my dearest friends, Marianne and Barb.



Barb and her husband John visited us this summer at OBX. We visited Marianne at her house in PA a few years ago, but I have not seen her since. They have decided to try the life of a snow bird and have been here in Florida, so I was thrilled to have both of them close enough to see and hug in person.



I have never been to Gulfport, so it was fun to visit a new place. As I drove over the bridge that spanned the water, I was soaking up the goodness of all of the water! Once I arrived at their condo, we went outside and soaked it up some more.



It was such a pretty view!



I even saw their water friends, a pair of dolphins...although this is the best picture I managed to capture of them.



We even got to grab dinner together at a place that I think was named O'Maddies, where I learned something new: orchids are edible. I had no idea!





The visit felt too short due to it just being a day trip, but it was still so worth it to see my special friends! I told them if they come back next winter to plan on another house guest for at least some of their time here so we can really have a gab-fest!

Foggy Night






















The fog has really been settling in these past few nights.

Rider Fatigue and Bicycle Design

Randonneur Flying, Hanscom AFBWhile I'd heard cyclists speak of rider fatigue in relation to bicycle frame design and ride quality, I did not understand what exactly this meant until I got a chance to experience and compare a number of different bikes myself. Riding a variety of bicycles over the same routes, I've noticed that some make me more tired than others independent of the ride's intensity. I can be cycling strenuously on Bike A and really feeling it in my leg muscles, yet remain energetic for the duration of the ride and even feel"refreshed" rather than tired at the end. Or I can be cycling at a moderate speed on Bike B and not exerting myself much, yet feeling more worn out than during the more strenuous ride on the other bike.



A reasonable assumption would be that a heavier and slower bicycle would be more fatiguing than a lighter, faster one, but for me that is not always the case. It seems to have more to do with how the bike feels on the road. When a bike does not do a good job dampening road shock, I begin to feel exhausted very easily. I also seem to be sensitive to a bicycle frame's tubing, because some bikes just feel more effortful to propel forward than others, despite similar geometry, size and fit. Oddly, positioning does not seem to have as much to do with it for me as these other aspects: Some bikes I can ride for a long time in an upright position and some bikes I can ride for a long time in an aggressive drop-bar position, whereas on other bikes these very same postures begin to feel exhausting sooner.



What has been your experience with fatigue on different bicycles? Have you noticed any patterns or connections? I suspect that there is no one formula to this. No doubt it is a complex interaction between a number of factors, including individual anatomy.

Ice Climbing at the Asbestos Wall



I am really feeling like I’d like to get more into ice climbing.



Perhaps I should have said this before my last post about ice, but better to say it late than never: I know very little about ice climbing. The last thing I want is for someone who actually knows a lot about ice climbing to stumble upon these ramblings and come away thinking that I regard myself as some kind of real ice climber because I’ve toproped short, picked-out beginner walls on four occasions in my life. Obviously, I know I am a beginner. In offering my thoughts I hope to offer a beginner’s perspective on ice, and not much more.



With that out of the way, let me tell you about my day with V at the Asbestos Wall in the Catskills.



As the day approached, I watched the weather, hoping it would stay below freezing this time. On my last ice climbing day the temperature had spiked up into the mid-forties, leading to very wet and potentially worrisome conditions. This time around there appeared to be no problems in that regard. The high for the day was projected to be just 14 degrees, which is less than the ideal temperature, since when it is so far below freezing the ice can be brittle and chip off in plates when you stick your axe in it. But at least I could expect that this time it wouldn’t be so difficult to stay dry, and I wouldn’t have to worry about melting chunks falling on our heads.



I proposed to V that we check out the Asbestos Wall, mostly because I believed it would be easy for us to set up topropes. Neither of us was planning on leading. I of course have never led on ice, and while V has the screws and used to do it, our trip was going to be his first time on the ice in at least three years. So he just wanted to get a feel for it again and told me he’d prefer it if he didn’t have to lead.



I had never been to the Asbestos Wall, and in fact had never really considered trying it before because it has a reputation as an overcrowded nightmare, full of loud, inconsiderate gumbies hogging routes and hacking the ice into oblivion. It is also a very sunny wall and the ice tends to bake and get that milky/cloudy appearance that can signal poor conditions (hence the wall’s name). But since we were heading up on MLK Day, which is a Monday and a workday for many, I hoped it wouldn’t be too crowded. And with a forecasted high temperature well below freezing, this sunny area seemed like just the ticket.



When V and I arrived we immediately saw why the wall gets so crowded. The approach is incredibly easy. The ice is visible from the parking lot and the slope beneath the climbs is neither steep nor unpleasant. And although the sections of the wall aren’t terribly high—the tallest ones are maybe 40 feet, tops—they are generally vertical, with very few ledges or broken-up sections. Add to these virtues the ease of access to the trees atop the cliff and the place becomes a beginner ice climber’s dream come true.



All of this is provided, of course, that you have enough room to climb without fear of getting a rope dropped on your head. We met a woman at the wall who had tried to come the previous day (i.e., Sunday). She said her party had given up after being at the wall for less than an hour because they found the crowded conditions so miserable.



But on this holiday Monday we had no such issues. The woman I just mentioned was part of a group of three. There was a guided party and I think two other pairs at the wall all day. We found plenty of ice to share with this small group of climbers and had ourselves a great time. We set up ropes on three different sections of the wall over the course of the day, and at each section we were able to pick out three or four different lines to climb. We had no trouble getting a section of the wall to ourselves any time we wanted it. There were ample signs of the wall’s popularity; most of the climbs we chose had obvious pick markings, and some would have benefitted from some time alone to recover. In the most extreme cases there was evidence that fragile lower sections of the wall had been kicked out by clumsy, rough climbers who came before us. But there were some fat columns we climbed on which there was no evidence of prior climbers, most likely because these particular sections have so much water flowing through them that holes fill in and freeze over very quickly. We tried to find the least hacked-up lines we could, and took care not to cause further damage to any of the more fragile features we found. We had a fun day, one I’d repeat without hesitation. Even though the temperature was quite low we were in the sun until the late afternoon, and had no trouble staying warm, which of course presents another issue with this wall on warmer days, when it must be difficult to evaluate whether the ice is in good condition.



So I would recommend the Asbestos Wall highly, but only to beginners, and only on a weekday, and only when it is quite cold. It really is a sign of how popular ice climbing has become that you can find five parties at this wall on a weekday. I would guess that a decade ago you might not have found so many parties at this wall over an entire weekend. Now, it seems the weekend crowding is so bad that this wall becomes unbearable. Even during the week, I can’t imagine what this wallwouldoffer a solid leader on ice. There are better, longer, less-crowded climbs within a very short distance of this wall. But for easy access to steep toprope climbs, it’s pretty hard to beat.

Last Sunrise of




































Last sunrise of in Grand Portage on the Lake Superior shoreline. I had to scramble to get to this spot, mostly because I didn't give myself enough time to get there to scope it out before the sun rose. Luckily, I am quite familiar with this shoreline and know that there are some nice rocks there. What I wasn't expecting was this really neat cap of ice covering this rock, with icicles hanging down on the side facing the lake. It made for a really nice foreground.



I hope everyone has a wonderful, fun (and safe!) time ringing in the new year!

A Handful of Rust: Bicycles As Waste

One argument made in favour of the bicycle, is that it is a machine that is timeless. With proper maintenance and care, a bicycle can last for many generations. And those of us who own functional bicycles from as far back as the 1930s know that to be true - at least in theory. However, in practice garbage dumps throughout the country are full of discarded bikes. Countless abandoned bicycles rust away locked to urban fixtures until the city removes them. New bicycles are churned out by factories every day as old ones become junk. The bicycle's resistance to obsolescence is a heavily stressed selling point in today's green-hued marketing... and yet reality does not reflect that. When I am asked how I feel about thatcontradiction, it is not easy to respond without ruffling feathers.



Looking at bicycles that are rusting away abandoned, I notice a trend: It is not the oldest bicycles that are being treated as junk. In fact most of the bikes are relatively modern. The factors they have in common are awkward construction, crude workmanship, low-quality components, and a certain overall genericness that just seems to make them impersonal and unloveable. These are mostly bicycles from big box stores, or lower-end models from popular manufacturers sold at dedicated bike shops. The truth is that even when new these objects do not look "timeless" to me. They look cheap and destined for the dump within several years - seemingly by design. So when I am asked why I do not promote "more accessible" (mass-produced, lower-end, lower-priced) bicycles, that is why. I sincerely feel that the vast majority of those bikes are designed to be bought on a whim (why not? they are affordable!) and be discarded shortly thereafter.



Bicycles that are produced thoughtfully and with care cost more, because they are more costly to make, and there is just no way around this reality. But it is not such a bad thing if we perceive a bicycle as special and expensive. When an object is meaningful to us and takes time to save up for, we value it more. Even if the bicycle ultimately does not work out (or even if we lose interest in cycling altogether), we will be unlikely to discard or abandon it. Instead we will sell it or pass it on to somebody else- just as with any other valuable, well-made object that we no longer need or want.I think that I have a pretty good idea which of the bicycles marketed today will end up in the garbage dump 5 years from now, and which will be cherished and ridden, even if not by the original owner. The latter is the kind I want to promote and the former is the kind I do not.



For the same reason, I am conflicted about the bike share programs that have been popping up in major cities. My enthusiasm for the idea of bike sharing is dampened by firsthand knowledge of what happens to many of these bikes, and how quickly it happens. I have seen large municipal pickup trucks in Vienna come by the CityBike stations on a regular basis and cart away dozens of damaged bikes, replacing them with new ones. The wastefulness of the ParisianVelib system has been well documented as well. The sad truth is that people do not treat well objects that do not belong to them. And as much as I don't want to rain on the bike share parade, I find this problem difficult to side-step. There have been grassroots initiatives to use second-hand bicycles for bike share programs, but as far as I know they have been consistently rejected.



Do you feel that the current trend for all things bicycle will just generate more waste down the line, or is that a cynical view? How do you feel about bike share and the various methods of bicycle production in relation to this question?
