What is a Scrader Valve or Presta Valve?
When you ride a bicycle it will come to a point that you’ll need to inflate your tires. Soon, I’ll be going over how to change a flat, different types of pumps and what makes a tire tubeless, tubular or standard. For today we will be starting very basic and figuring out which valve you have and why you need to know.

A schrader valve is the commonly used valve in the U.S for automotive tires and most bikes under $1,000. The valve has a spring inside of it that opens and closes the valve core. The valve core is what keeps air from leaking out of your tire. On a schrader valve it is very important to have a valve cap (plastic top) to cover the valve to keep dirt out, if not the valve could stay open or jam shut.A presta valve is found on higher pressure bicycle tires or higher end wheels. This valve is much smaller in diameter and has a top nut that controls the valve core. You need to screw open this nut to let air into and then screw close to shut off the valve. Due to the fact the valve does not use a spring to control the valve core it is able to hold higher pressure in the tubes, leak less and also not need a valve cap.

Depending on your application both valves work great and are easy to use. The presta valve involves a softer touch to open and close that valve so you don’t damage the valve core but I have faith in you! We will go over pumping up the tires more in depth next week.

Preventative Maintenance : Lube Your Chain
Proper technique in lubing your chain will help prolong the life of your drive train also a clean bike is a happy bike!!
1. Pick a lube. There are dozens and dozens of decent lubes out there depending where you ride. I could write a whole post about the different lubes and when/where to use them. For now consult a good riding buddy or a local mechanic. Here in Charlotte I like to use ProLink for everyday riding, in the winter rainy months or when I head up to Asheville in the winter I swap over to a more wax based lube.
Let’s Talk Saddles : Intro
There are three comfort zones or places your body touches a bicycle. As long as you can bear the weight of your body okay between those three places without numbness, pain or pinching then you can ride all day long.
Today we will be touching upon the saddle. This is also the hardest thing to explain or go super indepth about in only one article. Think of this as the first of many thoughts on saddles or reviews. Please read through and email about specific questions you have about saddles to continue the discussion.
You’re riding your bike often now and you’re wondering what you need to do to keep it up, right? Maybe not but let’s pretend for the moment that you want to keep your bike ready, out of the bike shop and embracing the greasy ways of working on your own bike.
Checklist for my 1st Sprint Triathlon
My first sprint triathlon is this coming Sunday. If un-prepared is part of the training regimen I am right on course for an awesome first tri! Sure I had goals and plans of doing the whole 8 weeks to your first sprint tri but life, work and excuses got in the way. The one small advantage I have is the fact I work with 3 elite-level triathlon who have a bounty of knowledge.
What’s in Your Bag?
A common question seems to be : What’s in your bicycle bag?
The bag they are referring to could be my seat bag found under most of my saddles, one of my messenger type bags slung over my back on the way to work or the store, or maybe my Camelbak on the way to the local mountain bike trail.

Across the US budgets on summer vacations were tightened down around the waist in fear of what our economy might end up doing. One thing I saw this summer was many people purchased their family various bikes to do things close to home.
