My bike gloves for cold rain (as of winter 2012)

As a minor update to my previous entry on gloves, I have since gotten some neoprene paddling gloves for biking in cold rain (as I planned at the time). Specifically I got the MEC Humboldt 2mm gloves. They have been a complete success in this role.

Initially I thought that the gloves would be too cold (since they seem to be only partially neoprene with some thinner, more cloth-like lining at the sides of the fingers) but in actual use they've turned out to be more than warm enough for my commute riding. If anything they're a little bit too warm when it's warmer (for example, if it's 10 C and raining). They do get wet in the rain but they stay warm; if anything, they sometimes feel warmer when wet than when dry.

(Note that I don't go on extended rides when it's cold and raining.)

(The other MEC gloves I looked at turned out to have been replaced by the Humboldt gloves, which will undoubtedly be replaced by another version at some time. The 3mm Humboldt was substantially more awkward and less comfortable than the 2mm version when I tried it on, and given how warm the 2mm Humboldt is I suspect the 3mm would be significant overkill for me.)

A review of the Filzer dZ4L bike computer

This may be a good bike computer for someone, but it certainly isn't one for me. My experiences with two units have been negative.

My first dZ4L lasted only a few weeks after I bought it; it failed to survive a relatively modest Toronto autumn rain. As far as I can see, this is intrinsic in the design of the computer; the transparent plastic top seems to be simply pressed very firmly on the main unit, not sealed. This is basically tailor made for capillary action around the edges, so once you've got enough water exposure the water starts being drawn up the sides and into the main display area where it mists up the screen and then gets into the electronics. Result: dead unit.

After a year of more or less reliable operation out of the rain, my second dZ4L is now frequently failing to register wheel motion, resulting in either much too low speed readings or a total glitch. This appears to be due to the plastic mount warping (and expanding in the summer heat; hotter weather makes it worse and cooler weather makes it more reliable) so that it no longer firmly holds the computer against the mount contacts. It can simply stop working on its own, plus even small bumps seem quite prone to jarring it just loose enough. Rapping or pressing the computer into the mount can temporarily make it register again, but it's far from reliable and rather frustrating. Trying to use a map case or anything that rests near the mount on the handlebars is troublesome, because it seems very easy for a velcro strap or whatnot to put just enough pressure on the computer or the mount to let things come lose; even a very light touch can be enough.

I find this really unfortunate. The dZ4L's four line display is by far the best information display of any bike computer that I've seen, but a bike computer that periodically glitches out and drastically under-reports speed when I go over even a minor road bump is not a bike computer, it's an unattractive handlebar ornament.

(I may some day put this on the MEC website, where I bought my dZ4L.)

My bike gloves as of spring 2011

I bike in all weather conditions. As a result, I have a whole lot of bike gloves (and gloves that I use when I bike), and I'm often looking for better gloves. Because I feel like keeping track of this, here's my current list with notes about when I use them.

In order of decreasing temperature ranges:

basic MEC fingerless bike gloves

These are my warm weather gloves, say around 20C and upwards. I used to use the MEC commuter cycling gloves but last year switched to the 'road' gloves, which have less padding, and I think they work better with my very comfortable Ergon grips.

(I have very comfortable grips, so in the summer I wear gloves mostly to keep my hands from slipping with sweat (and partly to keep the grip pattern from printing itself on my palms). Padding is not necessary for this and seems to actually get in the way and make things less comfortable.)

basic MEC full-fingered gloves

Intermediate cool weather gloves for temperatures in the mid and low teens, especially on group bike rides. These are what I'll call 'skin' gloves, with no actual warm materials used in their construction.

(I'd give the MEC brand name, but MEC keeps changing things around.)

'Netti' mid-weight gloves

Cool weather gloves for the low teens and upper single digit temperatures. Unlike the MEC gloves they have some actual warmth and insulation, but not large amounts (and the side of the fingers are vented, which lets the cold air in).

I got these at Urbane Cycle, and they appear to no longer be in production. So it apparently goes with bike gear that I buy.

thin but insulated Castelli gloves

Cold weather gloves for around 0C; I believe they have some fleece lining. These are thin enough to be fully dexterous; I can comfortably use my DSLR while wearing them, for example, with only minimal fumbling.

I bought these at MEC a couple of years ago as the best cold weather gloves they had at the time, and they were okay for that but they are not really warm enough for serious sub-zero temperatures.

I can't remember the Castelli name for them but it probably doesn't matter since it looks like they're out of production anyways. There's a theme here.

Castelli Pioggia gloves

Cold weather gloves for sub-zero weather. These are much more insulated than my thinner Castelli gloves above, but significantly thicker and thus less dexterous (although they are still decent for this). They rapidly get too hot at above-zero temperatures.

In theory they have a waterproof liner layer, but I have never used them in the rain to put this to the test. If it worked it would be great; cold rain is one of the things that I don't have a good set of gear to deal with yet.

I bought these at MEC this fall as an attempt to get better gloves for sub-zero weather, and they have been a resounding success at this; they are actively comfortable in such weather, instead of merely sort of tolerable and survivable.

MEC 'lobster' style cycling gloves

I haven't yet biked in weather conditions cold enough to force me into these, possibly because I stop biking when the roads are covered with snow, ice, and slush. The few times I wore these (before I had the Pioggias), I found them not entirely warm enough without liner gloves.

I have some additional gloves that don't neatly fit into temperature ranges:

basic leather gloves with a light inner layer for warmth

These are currently my 'cold rain' gloves, because they're the only thing I have that is both reasonably waterproof and sort of warm enough. Before I got the Pioggias they were also my really cold weather gloves when worn with liner gloves; they were better than the lighter Castellis but not as comfortable as the Pioggias.

basic MEC polypro liner gloves

I used (and use) these for additional warmth underneath my leather gloves and the MEC lobster gloves. I can't remember if I tried using them with the lighter weight Castelli gloves, but I suspect that there wouldn't have been enough room.

I have read a fair amount of praise for neoprene paddling gloves as cold weather rain gloves, so I intend to get a pair when MEC gets them back into stock and experiment. I believe that MEC also sells waterproof shells, but when I looked at them in the fall none of them looked really attractive.

(The leading paddling glove candidate is the MEC CyclPad 3mm gloves, with the MEC Catch Neoprene gloves as a second option. The MEC Humboldt gloves in 2mm and 3mm are new enough to not have real reviews.)

Sidebar: other cold weather gear I swear by

• a basic MEC fleece cycling headband. This is just the thing to keep my ears warm on cool days, and keeping my ears warm turns out to make me much more comfortable.

• a basic MEC fleece skull cap thing, with ear covers; I wear this under my helmet in subzero temperatures. MEC has cycling specific ones, but I believe mine comes from their general cold weather gear because I didn't like any of their cycling-specific ones at the time that I was looking a few years ago.

The novelty of frozen brakes

A disconcerting novelty happened to me a few weeks ago: my front brakes froze solid. As far as I can tell, I mean that literally; not just that they seized up, but that they seized up because they were frozen. As you might imagine, it was more than a bit disconcerting to squeeze the front brake lever and have it have no give at all, especially since the front brakes are the more powerful ones where you do most of your braking.

(This is not always the case for me, but that's another entry. Someday.)

My best theory on what happened is that in previous days some water had worked its way onto the brake cable and into the front cable housing (perhaps from spray thrown up by passing cars) and had not drained away. When I took the bike out in sub-zero temperatures with significant windchill, the water froze and locked the cable and the ferrule together. Exposing things to warmth and working the front brakes improved the situation by melting things a bit and breaking the binding action, although they were not entirely better.

Ah well, winter biking can be interesting. (If it was easy and painless, everyone would do it.)

How to help bicyclists #1: don't do us any special favours

Let us suppose that you are a well meaning driver who wants to help out bicyclists, but you don't bicycle yourself (or at least not anywhere where you're sharing the road with cars) so you don't have direct experience to draw on. So, what can you do to help?

Paradoxically, one of the best things that you can do to help is to not do us bicyclists any special favours; to treat bicyclists just as you would any other vehicle (which is what they legally are, at least here in Ontario).

The problem with doing bicyclists special favours is that it makes you unpredictable, and bicyclists really want cars to be predictable. When a car deviates from what we expect and what it should do, we have no idea what it's going to do next; we have to slow down and assume the worst, not because we think you're malicious but because we just don't know what's going on.

The corollary to this is that if you do want to do a bicyclist a favour, such as letting them turn left in front of you, it will help a lot if you do something obvious to signal that you're doing it deliberately. This converts your unpredictable behavior (inexplicably slowing down, for example) into predictable behavior; ah, you're generously letting them turn.

(PS: please don't be offended if the bicyclist doesn't give you much acknowledgement of such things. Generally the best I can do is to give you a brief thumbs up in thanks, because I am otherwise too busy with the mechanics of signaling, turning, and so on.)
