This can be the result of a crash, mis-shift or most usually simply being in the wrong gear when the chain and derailleur are under the most load either when the road goes upwards sharply or setting off from a standing/stationary start. Here is a gear hanger in action – blink and you’ll miss it!

Believe it or not, it’s not difficult to replace the rear derailleur yourself. Unscrew the derailleur from the derailleur hanger by inserting a hex wrench and turning counter-clockwise. The derailleur will now come away from the hanger. Remove the derailleur cable by loosening the hex bolt on the cable retaining clamp.

3 Answers. Derailleurs will last almost indefinitely. The jockey wheels will wear out in time (tens of thousands of km) but the rest of the mechanism shouldn’t see significant wear.

How to replace a derailleur hanger? If your derailleur takes a hit during the ride, the derailleur hanger (sos hanger) purpose to absorb the impact. If the gear hanger gets bent or damaged, you will need to replace it.

derailleur hangers are usually 10-20 bucks depending on the brand. You may be able to have the hanger straightened, but I would put a new one on for the reasons rockcrusher gave. as for the cost of tuning the derailleur, depends on your location.

Carrying a spare derailleur hanger will help you when you’re at a loose end. You wouldn’t think a derailleur hanger would be such a crucial and essential part on a bike. Not many people know how important they actually are, but they help protect your bike frame from being damaged by snapping.

Service & Repair

A department store quality bike is almost never a good repair investment. If the integrity of the frame is compromised, it’s time for a new bike. If the frame is bent, cracked, rusted through, has broken welds, a stuck seatpost or bottom bracket, it’s time for it to be retired.

A Bike tune-up consists of:

• Cleaning any dirt, oil and old grease off the bicycle.
• The gears and derailleurs are checked for damage and alignment.
• The drivechain is checked for stretching or kinking.
• Brakes are inspected for wear and grip.
• The tires are checked for wear, cracks or swellings.

Depending on your area, the average bike tune-up costs anywhere between $60 and $100. Most shops offer two options – A Minor/Basic Tune-up that costs $55 to $89 and a Major Tune-up that typically costs between $119 and $150. Cost often depends on the services included in the tune-up.

A yearly tune-up is definitely a good idea, but I also agree with the guys above. Get a manual and teach yourself. You’ll learn how to do minor adjustments every couple months or so to keep your ride running right instead of waiting a whole year and risking damaging something by riding a bike in need of adjustment.

Can I use WD-40 to lube my bicycle chain? No. You should never use WD40 as chain lubricant since WD-40 is NOT a true lubricant since it’s primary use is as a solvent or rust dissolver.

Accepted Answer: Firearms, Drive Chains & Gears

• Firearms – You should never use WD-40 to clean or maintain firearms.
• Drive chains of any type – Because WD-40 isn’t a lubricant, it really will not work well on drive chains of any type.

The fluid consists of two components – Vaseline, which proved to be one of the best lubricants, and a special kind of thinner that helps to get the Vaseline deep into the chain links. Once the thinner evaporates, Vaseline will do its best to make your chain running quietly.

In terms of adding lube in between cleanings, every week or two should be fine, more often if the drivetrain is getting noisy. Just a few drops of lube should be enough, unless you ride on very dirty roads. I would say that it is best to clean and lube your chain after every ride.

Best chain lube: Wet lube

• Green Oil wet lube. Green oil’s wet lube is fully biodegradable and is made from 100% natural ingredients.
• Muc-Off wet lube.
• Weldtite TF2 Extreme wet lube.
• Finish Line Teflon Plus dry lube.
• Boeshield T-9 dry lube.
• White Lightning Clean Ride dry lube.

Backpedal a few revolutions, then use a clean rag to wipe off any lube that didn’t work its way into the bearings. It can get messy, so use sparingly. Never Use: Grease—it’s way too heavy for this application, and it will gunk up pulley bearings and attract crud.

We recommend cleaning your road bike monthly (or every 20 to 25 rides) and a mountain or ‘cross bike more often. If you need some guidance, watch the video above for a demo on how to properly clean your bike, and keep reading for a few tips and tricks to make the cleaning process less of a hassle.

Water: When used carefully, water can be a handy tool, but be careful here. Water, especially when coming from a high-pressure hose, can cause damage to sensitive bearing systems throughout your bike. Soap / general cleaner: Use diluted dishwashing soap or preformulated bike wash cleaner for frame cleaning.

The best way to wash a motorcycle or any vehicle is to use a mild shampoo. You can use hair shampoo, bath gel too – but they’re meant for humans, not metal/plastic – use car wash shampoo to wash. More important, use a microfiber cloth to wash and dry the car/bike – and even for dry wiping.

Clean bike, full hearts, can’t lose. It doesn’t need a wash every single day (though it won’t hurt), but regular care will keep it in tip-top order.

Don’t use high-pressure car washes/washers Yes, it will blast off dirt and debris and can even strip gunk from the drivetrain. The high pressure can also force itself into the tiny spaces between chain parts, leaving your bike with an annoying squeak that isn’t easy to silence.

Washing your bike regularly will ensure all your expensive bike parts have a long and happy life. Whether you ride a road bike or a mountain bike, taking the time to wash your bike (especially your drivetrain) is a necessity. For road bikes, we suggest degreasing and “re-greasing” your drivetrain every 100 miles.
