ToolTime #2 Tire Levers & Jacks (with video ☺)

Tuesday, May 27th, 2014

tooltime2

Here we go! Today we get to talk about tires, Tire Levers and the Tire Jack – what on earth is that? (Find out below!)

Tire Levers (Tire Jack Below)

Tire levers look like fairly unremarkable pieces of plastic, but they are an absolutely vital tool! If you have ever had a flat, chances are that you – or the mechanic who repaired your bike – made use of tire levers. With modern pneumatic tires, levers are required to get to the inner tube that rests under the tire.

The tool usually has one end that is tapered and slightly curved.

Sets of three for particularly tough tyres!

Usually the other end has a hook so that it can be hooked around a spoke. A common feature is a lack of sharp edges because the slightest pinch of an inner tube can puncture it. (Ironic getting a flat while changing a flat!)

For this reason it is best to use levers that are plastic, but should you have metal levers – an older style – be sure to inspect them for sharp edges and file them until they are round and smooth.

History

Tire Levers are the common name for the tool today but they were formerly often known as Tire Irons, so called because they were made of metal. They are now called Tire Levers because they are usually made of plastic (whoa! :D). Tire Irons were also used for automobile tires but fell out of use in the 1950s when tubeless tires for cars became popular. But the tool is still very common for bicycle repair.

The Tire Lever became inevitable with the invention of the pneumatic tire with a separate inner tube and tire. Here is a quick look at the timeline for the development of the bicycle tire:

  • 1790 the first bicycle ran on wheels made entirely of wood.
  •  1870 penny-farthings made use of solid rubber tires
  • 1887 John Boyd Dunlop created the first practical pneumatic tire for his son’s tricycle
  • 1889 Dunlop founds the Dunlop Pneumatic Tyre Co. Racers quickly adopted the pneumatic tire for the increase in speed it provided.
  • 1891 the detachable tire was introduced by Edouard Michelin. It was held onto the rim with clamps instead of glue and could be removed to patch the separate inner tube.
  • 1893 August Schrader and his son George Schrader invent an improved valve to hold air in the tire.
  • 1911 Philip Strauss invents the combination tire of air-filled inner rubber tube and outer rubber tire.

Modern tires are usually either tubular or clincher. Tubular tires are a made of a single tube attached to the rim with an adhesive, usually glue that is required to set. They do not require the use of tire levers – but watch out if you get a flat tire!

Clincher tires are far more common and have a wire or kevlar bead that interlocks with flanges on the rim. A separate airtight inner tube is enclosed inside the tire. This is the common modern tire that most people are familiar with. When you get a flat tire, you (usually) just have to change the inner tube.

Fun fact: Tubeless tires are making an emergence in the off-road world. These tires are essentially a clincher without a tube, and the air is sealed just like a car tire. What if you get a flat? Stick a tube in and roll on! (but the odds of flatting with tubeless tires are much less!)

The neat thing about tire levers is the shapes and types you can get:

We have a fair number of these around the Bike Kitchen so find out which is your favourite!

Usage

Tire levers are used to fix a flat tire. Fixing a flat tire is a good skill for any cyclist to know. It requires tires levers, as well as a patch kit or a new inner tube that fits your bicycle.

First, release your brakes and remove your wheel from your bicycle so you can get started!

a) Check for Damage:

  1. Deflate the inner tube of the wheel completely by pressing down on the inner part of the valve.
  2. Using the scoop side of a tire lever, pry the edge of the tire over the wheel rim. Hook the other side of the tire lever to a spoke to secure it in place.
  3. Take another tire lever and continue along the rim under the tire, until the tire is completely off the rim on one side – Check out this Swapping Levers video, from this guy who kind of looks like Ray Romano, that illustrates the process.
  4. Remove the tire and tube completely, being aware of the valve.  Note where the tire, tube and wheel line up – this information will be useful when looking flat tire culprit in a couple steps.
  5. Inflate the tube to find where the air is leaking from. Submerging the tube in water or using your lips or ear close along the tube can help find small holes.
  6. Check the rim and the inside and outside of the tire for sharp objects, especially examining the area of the tire and rim that lined up with the hole in the inner tube, if a hole was found.

b) Repair or replace the tube using a patch kit or a new tube

c) Put the wheel back onto the bike. Make sure it is centered and tightened. Ride on!

Tire Jack

Here is a cool tool for fitting  loose tires back onto the wheel – the technical lingo is “seating the tire on the rim”.

 Usage

This is our first weird and wonderful tool. How do you use this?

  1. You attempt to seat the tire on the rim using your thumbs and levers
  2. If this fails, and the bead (edge of your tire) goes too far into the rim, well, then we can use the tire jack!

Here is an instructional video by our mechanic Lucas:

Whoa! Cool stuff! And that’s it

Hopefully you found this useful and learned about a new tool. Stop by and check it out sometime!

Bike Co-op Group Rides – Keats Island Camping Trip Report

Friday, May 23rd, 2014

After cancelling the trip a couple times due to rain, this weekend the Bike Co-op finally made the adventure to Keats Island for one night to camp. We met at Café Musette after 8am on Sunday and had a surprisingly dry and sunny ride through West Vancouver to the ferry at Horseshoe Bay. Unfortunately missed the ferry by the smallest of margins, so hung out in the village for a couple hours until the next ferry (caffeination and snack time!).  A blustery, picturesque ferry ride to Langdale, a short wait in the rain and another smaller ferry later, we arrived on sunny Keats Island.

The trek to the campsite involved biking along the island’s gravel roads and then biking and walking our bikes along a hiking trail.  A hiking trail with road bikes was as ridiculous as it sounds. Eventually, it became too steep and rocky, so we locked up our bikes together in the middle of the woods and continued to the campsite on foot. Must’ve been an amusing sight for anyone passing by!

The campsite, Plumper Cove Marine Provincial Park, was complete with teenagers with a megaphone, an outhouse with toilet paper provided, and $8 bundles of firewood that served as fuel for our campfire conversations about bikes and gender. Island activities included climbing a couple epic trees, exploring the shoreline, climbing to the highest point and sitting on some bouncy moss, watching a beautiful sunset to JF’s homebrewed mead, and eating delicious food (vege stew with couscous for dinner and oatmeal with chocolate for breakfast. Mmmmm…).

Overall, it was a fun, laidback trip, testing the tents and Eva’s camping hammock well. We do recommend though that Keats in the future be considered a hike-camping or mountain-biking destination; road bikes were not ideal!

When: May 18-19, 2014
What: Bike camping to Keats Island!
Who: Jean-Francois, Sherry, Jordan, Tamara, Eva
Distance: 48km round trip from Café Musette to Horseshoe Bay, plus some on island biking

 


 

Recycling Party – May 28

Wednesday, May 21st, 2014

On the last Wednesday of every month, the Bike Co-op has a Recycling Party in our shop, the Bike Kitchen! Here are three reasons why you should come:

1. Stripping bikes is a great introduction to mechanics for people of all levels

Recycling Parties are a great opportunity for people of all mechanical abilities. For those with less experience, stripping bikes is a low-stakes introduction and will teach you how parts fit together and how bikes work. For those with more experience you will be able to share your knowledge with others, and hey, you might even come across an interesting part that you haven’t seen before, assuming you get excited about that sort of thing.

2. Interesting environment, volunteer hours, and complimentary dinner!

Come to learn, meet interesting people, see where the Bike Kitchen gets many of its used parts, and best of all receive a free pizza dinner for your efforts! It also doesn’t hurt that you will receive 3 volunteer hours towards your membership or other rewards.

3. We love helping people take care of their bikes, but when bikes are at the end of their usable life we make sure they are reused or recycled

Riding a bicycle is a really sustainable form of transportation but it still creates waste, especially in its production and eventual disposal. This is one of the reasons we make sure that even when a bicycle is at the end of its usable life, we still try to save as many parts as possible. Those parts and frames that cannot be saved are sometimes turned into art but otherwise we make sure that they are separated and recycled to the fullest extent possible ensuring that no bike donated to us will end up in the landfill.

This rad event is taking place on Wednesday, May 28th 6-9pm
