Chain Wear: What to Know and How It Can Affect You

Know the signs of chain wear and how you can check at home

Most people do not replace their chain often enough. This leads to the gears not shifting correctly and excessive wear on your chainrings and cassette. Chain wear is affected by a few things: riding conditions, riding style (masher vs spinner), and shifting technique.

Know the signs of chain wear and how you can check your bike at home.When the conditions are wet the chain is going to wear out faster due to the dirt that gets in the rollers of the chain. Wet weather also tends to wash the lube off of the chain much faster. Cleaning your drivetrain can extend the life of your chain. If you ride at a low cadence you will wear the chain out faster than someone who rides at a higher cadence. The last major thing that affects wear is shifting technique. If you tend to cross chain a lot (riding in the big ring, big cassette cog or small ring, small cassette cog) then you will put more wear on the chain and chainrings.

The easiest way to check for chain wear at home is to measure 12 links of your chain. A new chain measures 12 inches per 12 links. Anything over 12 1/16 inches is too long. This bike tool measures it quickly and costs less than $10. A ruler also works just fine. You should expect to get anywhere from 1500 to 2500 miles out of a 10-speed chain and about 2500 out of a 9-speed chain. You can help your chain last much longer if you take good care of it, keep it clean, shift correctly, and ride at a higher cadence.

Follow these 6 Simple Steps for a Clean Drivetrain

You should strive for a clean drivetrain

While you’re hanging around this summer, why not try your hand at making sure you have a clean drivetrain? With these simple steps, you’ll be the grease monkey you always dreamed of being! Not only that, but keeping your drivetrain clean and lubed extends the life of your bicycle and helps maintain proper shifting performance and pedaling efficiency.

Steps:

1. When riding primarily on roads, you should clean and re-lube your chain at least once every three or four rides, depending on the conditions (rain, excessive road grit, etc.).

2. Run the chain backward through a clean cotton rag until the chain is fairly clean and dry. Lube the chain with your favorite lube, making sure that some lube gets on each link. Run chain back through the rag once more to remove excess lube. Don’t have a favorite chain lube? Check out 2 of our favorites White Lightning Clean Ride or Bike Medicine Purple Extreme.

3. Clean the cassette or freewheel. You can “floss” the cassette or freewheel with a clean rag to remove built-up gunk. If it is really dirty, you may want to scrub the cassette or freewheel cogs with an old toothbrush and some de-greaser.

4.  Wipe off your front and rear derailleur. Afterward, spray the derailleur pivots with a light, penetrating lube.

5. Wipe off your chainrings from time to time with a clean rag. If they are really dirty, you may want to scrub them with an old toothbrush and some de-greaser.

6. Clean the rear derailleur jockey wheels from time to time with a clean rag to prevent the build-up of gunk.

Tips:

If your chain is really dirty, you may need to remove it to clean it properly. However, if you regularly follow the steps above, you will not need to do this. You can buy chain cleaning kits which run the chain through a solvent bath. You can also use a wide mouth soda bottle, Gatorade bottle, or old water bottle as a chain bath. Again, following the recommendations above should keep your drivetrain clean.

You should generally replace your chain every 2000 miles. If you wait longer than that, your old chain may begin to put undue wear on your cassette or freewheel. Don’t forget to wash your bike!

Happy cleaning!

Replacement Timeline for Bikes

Take care of your bike and it’ll take care of you

Triathlon season is rapidly approaching for most triathletes! If you’ve been riding all winter or are brushing the cobwebs off, take the time to learn about/be reminded of a replacement timeline for the parts on your beloved road/tri bike. Whether Kerrville Tri is the only race on your calendar or you’ll close out your tri season on the most scenic triathlon course in Texas, the below replacement recommendations will help ensure your trusted ride is ready to roll when you exit T1. Keep in mind, every triathlete’s replacement timeline is different. If you ride more frequently replace your parts sooner.

Bike care replacement timeline

Bike care is as vital as training.

Tune up: once a year or as needed
Cables replaced: replace every six months or as needed
Tires: 2500 miles
Tubes: until they flat
Chain: 10-speed: every 2000 miles; 9-speed or less: every 2500 miles
Cassette: replace every 15,000 miles (if the chain is replaced regularly)
Bottom bracket: replace when loose or rough
Brake pads: replace when worn halfway through
Bearings: replace when rough
Carbon bars and seat post: replace every 1.5-2 years.
