The main problem areas are the handlebars, stem, and seat post, where pressure and friction can loosen bolts. Tighten Up Loose Boltsīicycles are held together entirely by nuts and bolts, so before heading out on a two-wheeled jaunt, make sure all hardware is secure - but not too tight. Even if the tune-up just re-attaches the old chain, expect to pony up for the cost of labor. Many bike shops will replace a slipped or broken chain with a brand-new one, which can get pricey. A very basic chain tool goes for $15, although more expensive models can run you $100 and up.

Lastly, use the chain tool to push the pin back through both parts of the chain and then use hands to loosen up the new connection.

Thread the chain back over the crank set and through the derailleur with the end of the pin sticking towards the outside of the bike.

This will shorten the chain, which affects the quality of the ride and also puts stress on the derailleur over time.

Lacking links? For a short-term solution, it’s ok to just remove the busted chain and link the remaining ends together.

Make sure the chain has one “female” end and one “male” end so it can seamlessly link together again.Attach the new links to the chain, using the chain tool to push the pin into the links. If spare links are available, this is when they come into the picture.

Make sure the pin is still partway through the link because it’s very difficult to re-insert a pin that has been totally removed. Put the pin through the broken link and clamp down until the chain breaks apart. The first step is to get rid of the broken links using a chain tool.To remove extra chain links, or to fix a broken chain, check out these further instructions: If the chain keeps falling off, it’s probably too long for the bike frame. Once the chain is in the right place, slowly turn the pedal forward, which will pull the chain around the entire chainring and back to the cogset. The last step is to reestablish the connection between rear cogset and front chainring.

When the chain is attached to the cog, drape the chain over the teeth on the top of the front chainring.Place the chain back in the bottom groove in the rear cog first.Usually when a chain falls off, it falls out of the rear cogset and/or the front chainring (part of the crank).But putting the chain back on is pretty simple and requires no tools at all! Here’s what to do:

Mechanics charge for the materials, plus about $20 for labor.Ī slipped-off chain can turn a pleasant jaunt into a ride from hell.

Inner tubes cost around $10, while a patch kit will set you back roughly five bucks. Sometimes patches don’t stick well to high-pressure road bike tires, so this is definitely a short-term solution for a tire puncture. The process is pretty similar instead of grabbing a new tube find the hole by gently inflating the inner tube, slap on a patch, and stick the repaired tube back into the tire. *Note: if you’re unlucky or just unprepared and don’t have a spare inner tube, a patch is the way to go.

Don’t forget to shut the quick release valve.

Again, use those thumbs to stick the tire edge back into the rim, and use a bike tire pump to re-inflate the whole shebang to the correct pressure.

Reverse the process by sliding the inner tube into the outer tire.

Take the new inner tube and inflate it about halfway, so it has some shape.

Just be careful when removing sharp objects - anything that cuts a tire can easily cut a finger, too. This is a good time to find the hole - a piece of rock, glass, or tree branch sticking out of the tire is usually a good clue.

Take out the inner tube*, being sure to lift the tube over the valve.

Removing a tire without tools just requires dexterous thumbs and a bit of elbow grease.

Next, wedge two or three tire levers under the edge of the tire, until it pops out of the wheel rim.

Then, push the metal valve up into the tire so it doesn’t stick out on the inside of the tire. Open the lever, remove the wheel, and let the remaining air out of the tire by opening the valve.

Most road bikes have a bicycle wheel quick release, which makes it easy to pop a wheel out of the frame without any tools.

Here are six steps to get bike wheels bouncing again. It’s a good idea to always travel with a spare inner tube, just in case. If the tires start sagging right away, it’s time to deal with a puncture.
