I’ve worked in bike shops and the bike industry for a lot of years and I firmly believe that of the most important relationships you’ll ever have in cycling is with your local bike shop, and more specifically, with a mechanic you trust. But out on the road and in between trips to the mechanic, there are some essential mechanical skills every cyclist should know. Once you master these skills you will not only be a safer rider, but you will also avoid premature wear on your bike and accessories.
Safety Check Both Bike & Gear Before Rides
We all can get in a habit of simply hopping on our bike and riding off, assuming that our bikes are in the same condition as your last ride. A quick safety check before every ride should become second-nature, especially if you frequently travel with your bike (even to the group ride or the local trails). It’s rare, but even experienced cyclists have left a quick-release dangerously loose every once in a while. A full once-over every couple of hundred miles would also help you find minor problems before they become major ones!
- Inflate tires & inspect for cuts or wear (explained below)
- Check headset of the bike by grabbing your front brake and rocking the handlebars back and forth. If you feel any movement or knocking your headset needs to be tightened. To confirm, you can put your fingers on the junction of the headset and frame as you rock the bike forward and back.
- Tug gently on the quick releases on both wheels to ensure they are fastened down snuggly. When in doubt, open completely and retighten.
- Grab each brake lever individually and pull tightly while trying to roll your bike forward. Your brakes should fully engage and keep your wheel from moving.
- Pick up the front end of your bike and softly spin your wheel. The wheel shouldn’t brush up against your brake pads. Repeat with the rear wheel of your bike.
Every 2 weeks or 200 Miles, whichever comes first:
- Lube & check chain life (explained below). If you’re riding in excessively dry or wet conditions, you may need to lube your chain more frequently. A dry chain will squeak and squeal. A dirty chain will sound gritty and crunchy.
- Inspect brake pads front and rear. Most pads have grooves in them, and you should see daylight looking through those grooves when looking from the top of the bike down through the brake pads. If your pads are so worn there are no grooves visible, they need to be replaced.
- Inspect cleats on your shoes to ensure they aren’t worn too thin.
- Remove your wheels and wipe off your frame top to bottom while looking for any imperfections in the paint or frame.
- Pat yourself on the back for being a wonderful bike owner.
Properly Inflate Tires & Fix a Flat
Your performance road bike tires need their air checked every 3-4 days depending on storage conditions. These tires hold very low volume of air under very high pressure. Keeping tires at the right pressure typically between 80-130 psi, depending on rider weight, tire size, and road conditions, will make your tires last longer, prevent flat tires, and provide a reliable riding surface (always stay within the manufacturer’s recommended pressure).
Mountain bike tires can be checked less frequently as they have higher volume under lower pressure, but I still check mine every ride as a few psi difference can drastically change the handling of a mountain bike. Mountain bike tires are generally inflated between 30-50 psi, but again that depends on the tire volume, rider weight, and trail conditions.
Fixing a flat tire does not have to be as intimidating as it sounds. Practice at home while watching a video several times and carry everything you need to fix a flat with you on a ride!
Recommended gear to carry with you to fix a flat:
1 Tube that fits your bike. Keep in mind, it’s not just the tube size that matters, but also the length of the Presta valve, especially for medium and high profile carbon rims.
1 Patch kit to repair tubes in a pinch
1 Inflation device – I am keen to a pump that is both a CO2 inflator, and a hand pump
2 CO2 cartridges that fit your pump
2 Tire levers
1 $5 bill to boot your tire, or pay a friend for their tube[blog_promo promo_categories=”camp” ids=”” /]
How to Lube & Check Your Chain
Properly lubing a bike chain is one of the most underutilized skills of bike ownership, next to knowing how to change a flat tire. Keeping your chain clean and lubed will prolong your drivetrain life and save you a great amount of money in the long run!
Steps in lubing your chain:
- Lean your bike against a wall in an area where the ground can get dirty
- Clean off your chain with an old rag or sock by gently grabbing the bottom section of your chain and back pedaling. About once a month, or anytime your your chain is especially dirty, using a chain cleaning tool (like this one) will make the job easier. You don’t need to use a cleaning tool every time you relube the chain.
- After you have cleaned off your chain apply a gentle stream of your favorite lube (I personally use a Dry Lube) on that bottom section of your chain again while backpedaling 3 or 4 full rotations
- Let the lube soak in for a while and then wipe off the access with a clean section of your rag by duplicating Step 2. I recommend to customers in the shop to lube their chain after a ride and wipe off the excess before they ride. The goal of lubing your chain is to penetrate inside the links, and not bathe the chain in lube.
- Your chain should have a nice glisten to it, but never sweaty or squeaking.
How to Adjust a Cable Pulled Derailleur and Brakes
Although electronic shifting is growing in popularity, most bikes still use cables to pull brakes and derailleurs. These cables work under tension, and understanding this tension is key to having reliable brake and shifting systems.
Adjusting Road Brake Tension
Over the course of a few hundred miles, your brake pads will wear down and you’ll want to pull in the pads so that you have that nice firm braking modulation.
To do this you need to tighten the brake cable, or add tension to it, by simply turning the barrel adjuster on the brake caliper ¼ turn at a time. If you are looking down at the barrel adjuster from the bike towards the brake caliper, turning counter-clockwise and essentially turning that adjuster out of the caliper (lefty loosey) and taking up room on the cable. This tightens the cable from the brake lever to caliper and moves the brake pads closer to the rim. If your brakes feel too tight, turn the adjuster clockwise ¼ of a turn at a time.[blog_promo promo_categories=”bucket list” ids=”” /]
Adjusting Road Derailleurs
Derailleurs are a complicated system and probably one of the most complicated parts of your bike, but making basic adjustments on them is remarkably simple! Your bike should come fully tuned and ready to ride but often after the first 100 miles your gears don’t feel as crisp as they did on day one. You aren’t imagining anything. Typically, it takes a couple good rides for everything to set in, but the good news is that after this break in period you shouldn’t need to adjust too much until you replace cables or parts.
To fine tune your shifting we are using the same idea as the brakes, using barrel adjusters to increase or decrease tension on a cable, either directly on your rear derailleur, at the front of your frame, or built in-line with your cable system. This can be done from either the saddle of your bike, or when your bike is hanging from something like a stand or tree.
Front Derailleur Adjustment
Keep in mind: The front derailleur pulls opposite of the rear and moves much further between shifts. If your front derailleur is not shifting smoothly to a hard gear turn the cable adjuster that is connected to the cable from your left shifter counterclockwise 1/8 – 1/4 of a turn at a time. Do the opposite if it isn’t shifting to an easy gear. Repeating the steps above until perfect.
Please note that depending on how your inline cable barrel adjuster was installed it can change the direction you need to turn the barrel adjuster. If you are trying to adjust shifting to move the derailleur out further when you shift to the big ring, you need to increase the cable tension by unthreading the barrel adjuster which will effectively lengthen the cable length. The opposite is true when adjusting to the small ring.
REAR DERAILLEUR ADJUSTMENT
If you don’t have a cable adjuster at your right shifter for your rear derailleur, you can use the barrel adjuster at the rear derailleur to make micro-adjustments. If your chain is not shifting to harder gears (the smaller cogs) smoothly, turn the barrel adjuster clockwise 1/8 of a turn at a time. This reduces tension on the derailleur cable and moves the chain toward smaller cogs. Test the shifting for any improvement after each 1/8 turn. If the shifting is now slow to the easier gears (the larger cogs) turn the barrel adjuster counterclockwise 1/8 of a turn at a time and test again for smoother shifting. Use the same concept if you’re adjusting the rear derailleur cable tension from either an inline barrel adjuster or one located at the front of your frame. More cable tension moves the chain in the direction of larger cogs; less cable tension moves the chain in the direction of smaller cogs.
Prepare to Perform Your Best
Becoming a great cyclist isn’t only about developing your engine, but keeping your bike ready to perform as well as you do. Take some time each week or month to practice the above skills to keep your bike running as well as you are.
