Bike Commuting Is Fun And Cheap!
Is the daily commute wearing you down? Through-the-roof gas prices; traffic jams; non-existent parking; lovely mornings and afternoons wasted inside your vehicle—what's there to do? Commute by bike! It's fun, it's fast, it's easy, it saves money, reduces global warming, and keeps you healthy and happy, too!
The path the chain takes from the chainrings (in front) to the cogs (in back). Check chainline by placing a straightedge between the chainrings and seeing where it lines up on the cogs. Ideally the chainline will be in line with an imaginary line that bisects the chainrings and cogs. That will ensure a smooth, quiet-running chain and smooth shifting. If the chainline is misaligned it can cause shifting problems and even possibly throw the chain off.
Today's Cycling Tip
Pedaling narrow trails requires special skills that you can develop and improve during every ride. Here's what IMBA recommends:
Start by keeping your arms flexed, not locked. On rocky or rutted trails, try to follow the path of least resistance. Imagine where you want your bike to go, and don't focus on the obstacles you want to avoid (if you do, you'll probably hit them). Learn to use both your front and rear brakes. On steep climbs, lower your elbows and drop your upper body closer to your bike's top tube. This helps you maintain tire traction. Finally, hold the handlebars firmly but not with a death grip as too much squeezing will tire you out and increase steering mistakes.
