Wednesday Night Group Rides
Thanks for another great year of riding ... despite the rainy weather. Unfortunately, due to a wet & cold forcast for October, this month’s Wednesday Night Gearhead Group Rides have been cancelled.
Still lots of people out on the trails though until the snow flies and still even then, so grab your bike whenever you have a chance and keep ridin’ ... keep smilin’ ... you won’t be alone out there.
Cold Weather Riding Tips:
Riding Technique
Try to pedal smoothly and relax your upper body, especially on ice and soft snow.
When the bike starts going sideways, make small corrections rather than oversteering and weaving down the trail. Practice riding in a straight line when the trail is good so it’s easier under bad conditions.
On some soft trails, higher speeds take less effort than lower speeds.because your tires sink into the snow less at higher speed.
Tires
Wide tires with widely separated knobs work best on snow.
Use low pressure: start with 15-20 psi and experiment for yourself. Sometimes 5 psi feels great.
Studded tires improve traction on ice.
Lubrication
Bicycles don’t need to be "winterized" the way cars do. The loads on bicycle bearings are so slight that just about any grease will protect them. We put low temperature grease in bicycle bearings to make them easier to pedal and steer. Some bicycles have grease in their freewheels that can cause problems when it gets very cold. We can disassemble the freewheel, clean it out, and put small amounts of low temperature grease in the right places. The grease we use is good year round, it doesn’t have to be changed for summer. So, if your bike works in the cold, it’s already "winterized."
On the other hand, bicycles that are used regularly end up with more dirt and water than grease in their bearings and yearly repacking will make them last a lot longer So repack bearings in the fall with low temperature grease and call it winterizing.
Lighting
Flashers are best mounted on your bike or rear rack, where they can be aimed precisely, rather than on clothes or packs, where they shift around. Many people install more than one rear flasher.
Winter trail riding requires surprisingly little light; 4-5 watts is plenty The snow reflects well and there are no other light sources so your eyes can adapt to low light. If the moon is bright or the clouds are reflecting light from the city, try turning your light off. For long trail rides try installing a lower wattage bulb to get more battery life. Make sure to match bulb and battery voltages.
Reflectors are available as vests, straps, tape and plastic pieces that mount to bicycles.
Clear (white) reflectors return twice as much light as amber ones and more than three times as much as red ones
Clothes
Cycling generates a lot of heat so clothes that are warm and comfortable have to control the buildup of heat and moisture as well as insulate and protect from wind.
Your particular metabolism, physical condition and riding style will determine what’s needed to keep you warm. We see people who ride in Carhartts and bunny boots and others who ride in lightweight ski gear. You’ll have to experiment.
Your outer layer on top and bottom should have a windproof front and breathable sides and rear.
Goretex and other "breathable" waterproof materials become clogged with ice at below-freezing temperatures. As windproof front materials these fabrics are acceptable but unnecessarily expensive. On the sides and back of your riding clothes they’ll trap moisture and freeze you.
Layer various weights of polypro, capilene, drilete or thermax under your outer, breathable/windproof clothes. Multiple light layers with neck zippers let you adjust your ventilation as you ride.
Your base layer (against your skin) and mid-layers should be synthetics or wool. Cotton in these layers will feel wetter and colder than the above materials. No T-shirts!
Over the years, the Kucharik company has most consistently offered clothes that meet our need for outer layers with windproof fronts and very breathable sides and back.
Windproof jocks, as used by skiers, are much appreciated by men. In an emergency, stuff a mitten or hat in your pants.
If you feel warm as you start out then you’re probably overdressed for any ride longer than a half hour.
Disposable heat packs can be part of your normal system or can be carried for emergencies. They come in hand and foot varieties and last for 2-5 hours, depending on conditions. The reusable types are heavy and bulky and less effective.
Carry headband, hat and facemask and try them in different combinations. Neck gaitors and balaclavas are variations on the theme you may find useful Your face, head and neck will need different amounts of protection as conditions vary. Uncovering your head is usually the simplest way to dump heat.
You may need to change the sizing pads in your helmet or remove them entirely to fit your winter headgear. Some hats are made specifically to fit under helmets. Try taping over the vents in your helmet if your head gets too cold.
If you’re riding in a headwind or falling snow you’ll find eye protection very helpful.
Miscellaneous
It’s easy to get dehydrated just living in the winter. Exercising outdoors makes it even easier. Dehydration causes decreased blood volume which makes us more susceptible to hypothermia and frostbite. It’s important to drink water frequently if you’re riding for more than one hour. Some people use insulated waterbottles but the most popular and generally successful system is the Camelbak, usually worn under the outer layer of clothes.
Below zero, cycling speeds generate enough wind chill to freeze exposed skin quickly. If parts of your face feel cold or numb, stop and warm them before they get frostbitten. If you’re riding with others, watch each others’ faces for white spots.
Be careful with glasses, watches, jewelry and zipper pulls. Small metal and plastic objects can get cold enough to cause frostbite.
Carry emergency food in your tool bag so it’s always on the bike. Energy food, like a Powerbar, works well
Carry an extra clothes layer, about 20 degrees worth. Windshells, an insulated jacket, something to keep you warmer if you have to walk for a while.
If your feet get cold, run with the bike.
Cover your tools with tape so you don’t have to touch cold metal directly when doing emergency repairs.
Few mechanical things work well when it gets very cold (say minus 30 degrees (F) or colder). Even a well prepared bicycle isn’t at its best then.
Steel gets more brittle at winter temperatures but I haven’t seen any steel frames or components break from the cold.
Aluminum and titanium don’t get significantly more brittle at winter temperatures.
Aluminum shrinks more than steel as it cools and on a bike with a steel fork and aluminum frame the headset will get loose when it’s very cold.
Plastics do get brittle and we see waterbottle cages, toeclips, pedals and the sheathing on cable housing break all winter. If the plastic cracks on indexed shifter housing, the housing will buckle and the shifting won’t work.
You can reinforce the shifter housing with heat-shrink tubing (available at electrical supply stores) to prevent this problem. The size that fits best is 3/16".
Elastomer suspensions generally stop moving between 20 F and 0 F but they don’t seem to be damaged by the cold.
Oil-damped suspension systems are often damaged by operating at low temperatures You can change the oil in them to avoid this or install a rigid fork
Only bring a cold bike indoors if you can keep it there until it’s dried off completely.
If you bring a room temperature bike out into cold snow and ride it immediately, the snow thrown up by the tires may freeze onto brakes and derailleurs. Some winter bike problems have very simple solutions.
As you ride through the winter questions and problems will come up. Feel free to come by or call; we want to help.
