Buying the Correct Tube for your Bicycle



There are a lot of different variations of bicycle tube.  Quick primer on getting the right tubes for your bicycle.

  • Wheel size (20", 26", 700" etc)
  • Tire diameter 
  • Valve stem type Presta or Schrader
  • Length of valve stem
If your bicycle has deep profile rims you may need a longer valve stem tube.  If you can measure the valve stem of your old tube.

The proper size tube is purchased to fit the Tire.  The width of the tire is the second number as in 26 x 1.75 or 700x25.  Tubes will usually fit a range of tires sizes.  For  example, Many 26" tubes will fit tires from 1.75 all the way up to 2.125.

I always buy a couple of tubes so I have a spare or three around to carry in my pack.

Check out the hundreds of different tubes we have available at Zbikenut on eBay

Seat Post Sizing and Installation Tips




I always put a little grease on the inside of the seat tube on the bicycle before installing my seatposts.  This keeps your seatpost from rusting into the frame.  If you live in a humid region your seatpost can rust solidly into your frame in as little as a year.

Always be sure to have the minimum insertion level inside your frame.

The size of your seatpost will usually be etched on your seatpost just below the minimum insertion line on the post.

We have a lot of seatposts available at Zbikenut on eBay.

My New Pedals Do Not Spin Freely!

Bicycle pedals are one of the most common replaced items on a bicycle.  They take a lot of abuse as all of our weight is often on them.  Another reason they are so often replaced is many department store bikes come with very low quality pedals that fail with relatively little use.

I am partial to aluminum pedals that have a one piece body and cage.




View the XLC Pedal on Youtube.

Do Not Readjust the Pedals

Usually when you first get pedals with a one piece body the factory will have adjusted the bearing so they are gritty and do not spin loosely.  Within the first 50 miles the pedal bearings will loosen up significantly.  If you adjust them before installation so they are smooth after about 50 miles they will become sloppy and need to be readjusted.

Thanks,

How to Save Money on MAP priced Bicycle items

MAP stands for Minimum Advertized Pricing.  It is being used by a several bicycle parts manufacturers and in many other industries.  Bicycle retailers and mail order guys cannot advertize these companies parts for less than stated or the Manufacturer will suspend selling to the dealer.

 HOWEVER the retailer can still sell it to you for any amount.  

 Most MAP policies also state that the dealer may not put “Make Offer” or “Call for Price” or “Too Low to Print” in their listing or advertisement.


 Get a Better Price Strategy
So any expensive item that you are looking to purchase that is MAP priced you will probably be able to get a better price by either making an offer, emailing for a better price, or calling for a better price.  In my experience you will not get a better price on a MAP item unless the retail cost of the item is over $25 or $30 or the item is very small and light to ship.

Buying and Installing Pedals on your Bike 9/16" vs 1/2"

When looking for new pedals for your bike the first thing is you must figure out the pedal axle size.  There are two common sizes of pedal axles. 1/2" and 9/16".

1/2" Pedals will fit bikes that have one piece cranks like the picture below.  Normally you will only find this style of crank on some childrens bikes and some adult one speed bikes.

Pretty much any other crank on a modern bike will take a standard 9/16" pedal***.

9/16" pedals
The Cranks below are examples of 3 piece cranks.  If you have three piece cranks then 9/16 pedals will fit.



A Little Daub will Do Ya
I always put a daub of grease on the pedal threads before installing them.

Junior Pedals VS Adult Pedals
The only difference between Junior pedals and Adult pedals is the size of the pedal.  I recommend the smaller junior pedal for most 16" and 18" wheeled bikes.  The beginner bikes have the pedals close to the ground so the smaller pedals allow the bikke to lean over further in a corner before the pedal hits the ground.



Left Pedal VS Right Pedal
The left pedal is always reverse threaded and the right pedal is always standard thread.  The left pedal will have striations on the pedal axle near the wrench flat that are not on the right pedal.  Often the axle of the pedal will have an R or a L designation also.

If you need new pedals often you can get a better deal with our Bicycle Pedal Kits on Ebay.


***Before 1990 there were 9/16" English (the current standard), 9/16" French thread (this was on Peugeot, Motobecane and other French bikes, and 9/16" Italian Thread.

Mountain Bike Shoe and Cleat Tips

Mountain Biking is a lot more enjoyable for me when I ride with clipless pedals and shoes.  I have been riding them since Shimano first came out with them in the early 90s.  Initially I had a lot of problem with the shoes because the soles would pull off.  I have not had this happen since 2002.



Clipless Shoes

There are two types of Clipless shoes.  Shoes for 3 screw Road bike cleats and shoes for 2 screw mountain bike cleats.



Normally you cannot put 2 screw cleats on road Shoes or 3 screw cleats on Mountain bike Shoes.



Most Touring Shoes are 2 Screw Mountain bike style.







Mountain Bike cleats are recessed in the shoes to make them better to walk in.  The cleat is usually recessed into the sole of the shoe.



Moutain Bike 4 Screw holes.  Many mountain bike shoes will have four mounting holes in the mounting location on the bottom of the shoe.  This allows you to mount your cleats further forward or further back.  You will still only use two screws. I have always mounted my cleats into the forward two holes.  I want the axle of the pedal directly below the ball of my foot.



Lateral and angular adjustment of the cleats.

There is usually a lot of adjustment in the angle of the cleats.  This is accomplished by mounting the cleats but not having them tight.  Then just move the cleat to the position you want and tighten.



Cleats mounted too close to the shoe.  The Mountain bike shoe around the cleat recess can sometimes get in the way of getting in and out of your pedals.  You can move most cleats in or out on the shoe when the screws are not tight.



Do Not Try To Ride without Tight Cleats

If you try to ride with your screws loose you may be able to get into your pedals but the cleat will just pivot on the shoe when you try to extract yourself from the pedals.



Here is a link to Bike Parts Quick Clipless pedals and shoes.



I love riding, and I rarely ride anymore without being clipped in.

Shimano PD-A520 SPD Road Bike Pedals

The Question about these pedals was will they work with Mountain bike shoes and with the SH56 cleat.


These pedals are designed for Mountain bike cleats to use on a road or city bike. Many people have really nice mountain bike shoes and want a pedal with better cornering angle for their road bike than most mountain bike pedals offer. This pedal was designed for that. If you are comfortatble flipping your pedal over every time you get on your bike these could work fine as mountain bike pedals. Yes they will work with Shimano SH56 cleats or SH51. Thanks
