How durable are the chain idler wheels?

The chain idler wheels spin on sealed bearings and are attached to the frame with an idler axle bolt. Their job is to guide the long chain through its journey from the front chainrings to the rear cogs with as little resistance and noise as possible. The chain idler wheels are a wear item like a tire. The front idlers average about 2500 - 3000 miles, some have lasted over 6000 miles (of course this is dependent on many factors). Rear idlers should last much longer than fronts. If you are not getting this type of performance from your idlers here are some tips: • Double check the alignment of your front boom tube making sure it is perpendicular to the ground and aligned with the balance of the drivetrain. A slightly skewed boom can lead to a twisted chain that can cut into the idler. • Keep your chain clean and free of abrasive contaminants. Regular maintenance on your chain will keep your machine running better and your idler wheels lasting much longer. • Periodically check the ...  more
