Winter Savvy Riding

 

Preparing for Winter Riding can be an "Abominable" Task!!

Let these tips make it seem more like a "Spring Fling"!!
The Tips:
Tires
Wide tires with widely separated knobs work best on snow.
Boazobeanna front and rear are the best tires we've found for soft snow.
Use low pressure: start with 15-20 psi and experiment for yourself. Sometimes 5 psi feels great.
Glue tires to rims: Use tubular tire glue or any strong contact cement in about 6 six-inch strips. Only glue one side. We always glue the right side so we don't have to try to figure it out in the dark.
Snow Cat rims improve flotation, traction and stability on snow or ice.
Studded tires improve traction on ice.
Chains improve traction on snow or ice but dig themselves in on soft snow and give a rough, slow ride on pavement.
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.
We test greases for winter bike use by putting them outside when it's minus 40 degrees (F) or colder. Some "low temperature " greases get a lot stiffer than others at those temperatures. The best we've found so far is Lubriplate Mag-1.
We have a lubricant for cables that stays liquid at minus 40 degrees (F). This can help your bike shift better in winter.
Goretex RideOn cables require no lubrication, so they work well no matter how cold they are.
Lighting
Most states require bicycles to have a white light in front and a red light in back, both visible at 500 feet, as well as side reflectors and a red rear reflector. Red flashers that meet this requirement are available for about $16.
White strobes are brighter and are visible at a greater distance but alone they don't meet legal requirements. Also, they blink less frequently, making it harder for drivers to see your position and direction.
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.
Headlights that meet the state requirements also start at about $16 These are basic, non-rechargeable lights that will make you legal, let you be seen and help you see under some conditions. This is often enough. However, people who ride longer distances and in all conditions usually use more powerful lights. One popular high-power system uses dual beams, produces 35 watts and costs $300. There are many systems available between these extremes. Each system offers a particular combination of power, endurance, weight and price.
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.
Generator lights don't work well in wet or snowy conditions and often don't give enough light at slow winter speeds. The less sophisticated ones give no light when you're not moving.
Systems that power the taillight and headlight from the same battery may leave you invisible from the rear if a wire breaks.without your knowing it. Independent rear flashers are very reliable and can run for at least a year on 2 AA cells.
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
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.
When riding in a group on soft trails, have the weaker, less skilled or badly equipped riders lead so they can use the trail before the better riders cut it up.
Snow machines leave the center of the trail soft. Their best tracks are left by their skis, if you can ride straight enough to use them.
Dogsleds leave harder, smoother trails than snow machines.
Road ice can provide lots of traction or very little. Learn how the different types look and sound. Try not to brake hard on the slippery sort, or if you must, use only your rear brake. Watch for dry patches where you can do your braking or turning.
