How cold is too cold?

[FlyingScot]

So, I'm thinking I want and need to continue riding despite the cold weather. Before I invest in cold weather gear I have a few questions. In my neck of the woods winter temps are usually in the low to mid 20's, very often in the teens and it's not uncommon to be below zero. Add wind to that and it gets mighty cold. So my question is how cold is too cold for a bike, its components and tires to function properly? How cold is too cold for a human to ride in regularly? My rides are typically 20-30 miles long so I suppose I'll have to shorten them. Would it be better to ride my hybrid than my road bike? I don't plan on riding through snow and ice so traction isn't an issue. It was 24 in the morning here and gorgeous with dry roads but I don't have the proper clothing and wasn't willing to freeze my arse off or damage my bike. Thanks!

I would think that at least on the components side, you'd have to have Alaska winter-type air temperatures--or even colder--to make them brittle, though I'm not exactly up on metallurgy. One thing you do have to worry about with winter riding is the road salt, so make sure the bike gets a regular bath after riding.

I think it comes down to your personal "lower limit" and proper clothing. I don't have a hard time keeping my core adequately warm (layers, baby!), but I do have issues with cold feet, hands and face. I'm working on solving the hand problem, and I have a balaclava that needs surgery so I can put a ponytail through it. My limit is about the freezing point, and I won't ride if it's wet. (I largely ride on paved trails, so no salt for me to worry about.)

A hybrid bike would be better to navigate through snow/ice. I was behind a woman cycling on her skinny tire roadie bike. She kept on putting down her foot abit to stay balanced. I didn't have to do that, I just cycled slower.

I've cycled as cold as -20 degrees C. (I assume since you are in Scotland it's imperial 24 degrees F.)

You'll need to try it and see how you feel. If the windchill is much below 25 F, I stay home.

Icebike.org everything you need to know

note, there is no mention of hybrids on the "what bike" page. Mountain bikes seem to be the bike of choice.
Lots of good info there.

Thanks for the info guys. I'm not so much worried about brittle metal as I am about cold or possibly frozen lubricants and what that might do to my derailleurs and other moving parts.. Also possible damage to the tires from cold, perhaps more risk of blow-outs? I'm likely overthinking this and probably should focus more on keeping myself warm but I don't want to be stupid about it. I did find a neoprene face mask with an actual respirator valve built into it which is a vast improvement over my regular one that gets wet around the mouth and nose. It makes me look like something from "Star Wars" but helps my asthma.

BTW, as much as I would like to be in Scotland I am, alas, located in the Midwest.

I stopped fasted cardio in the morning the moment I fell on ice and bruised my leg and my knee was swallen. The temperatures were below 0 (I use the metric system, so let's say in the 20s F). and I was doing my morning prework half an hour cardio on the bike when I stepped on frozen cobbled street. I was sliding a few meters (feet, ok) and couldn't stop. The descent there is about 15% so it was difficult to stop. I felt pain, I felt terrible and helpless. When I tried to stand up on my feet, I couldn't move because it was too slippery even for walking. After that I took my bike and pushed it in the bushes. It was a horrible experience and after that I have ridden a stationary bike at the gym in the mornings. I still commute to the gym and then to work by bike but it's only 10 minutes ride and I don't freeze my a**. Sometimes in the afternoons or on the weekends I ride a bike when the temperatures are higher.

You definitely don't want to be using your good racing tires in winter. There's more stuff on the ground that can cause punctures and nothing ruins a ride like changing a tube with your gloves off, sweaty and standing by the side of the road. When I ride in the winter, I just make sure to clean my bike afterward and I'll use a heavier chain lube if I'm doing a lot of winter riding. I'll also be sure to keep my cables well-lubed, especially if it's wet.

Good luck! I suggest giving it a try with what you have now to see if you like riding in the cold. Just layer up and refer to Bicycling's guide based on the forecast: http://www.bicycling.com/whattowear?...erence=0&x=&y=

I commute by bike through winter, at least until ski season is in full swing, then I'll slack off a bit. My commute takes 45 minutes to an hour and a half, depending on the route.

My commute is no problem at all down to about -5 C/23F. It's easy to dress for and the bike works just fine. I need studded tires once it gets icy, of course.

Down to about -10 C/14 F it can still be fine, but the bike starts protesting. Gears are more sluggish to shift. I have to wear yet another layer and think about how much cold air I pull in.

Down to -15 C/5 F can be a lot of fun to ride in, but it's not really that cycle-friendly. I usually have to settle for maybe half my gears. The air is dry, which is nice, but it's cold enough that if you're riding fast enough to break a sweat, having to stop for any reason is not much fun. Forget fixing a flat, or anything else that needs bare fingers. But biking to work is still warmer than hanging around waiting for a bus

Below -15 C I'll only bike very rarely, it's a bit too much of a hassle. Keeping feet warm is the hardest.

But in my experience snow is more of a dealbreaker than cold. Cold you can dress out, but snow you have to ride through. Falling, wet, heavy snow is bad, piles up and clogs everything, at the same time drivers are skidding every which way. Light dry snow is no problem.

Hybrids are quite common here and you can get studded tires for them, but most winter commuters seem to prefer mtb's. Maybe because they're more versatile and nimble when it's slippery?

PS. The only real mechanical problem I have regularly in winter is with plastic. Anything in plastic gets brittle and breaks easily. You also have to reckon on a lot more wear on the drivetrain. I've been told one winter can equal the wear of four summers, and I agree.

While OP isn't in Scotland, I'll still pitch in to say, Scotland uses the metric system!
