23mm tires vs 25mm tires

Lately there has been a great deal of discussion on which tires are better, 23mm or 25mm.  Some people argue that the 23mm are faster and others the 25mm.   Here is a summary of the pros and cons of each tire.  This might help you choose between tires next time you are due for new ones.


In the past few years the 23mm tire has become a tool mostly used by Elite Time Trialists.  Its low weight and ability to be ran at very high pressures seem to be an advantage for those seeking the ultimate performance over a short period of time. 

On average, a set of 23mm tires will save you 40 grams over a set of 25mm tires.  While this may seem like a good amount of weight, is it worth sacrificing other benefits to save 1/10th of a pound?  Some sprinters and professional climbers might argue that those 40 grams make a difference during that explosive effort, however, for most of us the difference is negligible. 


The 25mm tire wins all day on this one.  Ran at the same tire pressure the 25mm provides more cushion to your ride helping you ride longer without discomfort.  This usually translates into a more efficient and faster ride.  A tire that beats you up over the course of several hours is more likely to affect your performance than a slight weight penalty.

Rolling Resistance

While the 23mm tire has a narrower contact patch, compared to the 25mm it has a longer contact patch.  The wider but shorter contact patch on the 25mm tire produces less resistance.  It also helps in the traction department, when the width of the tire is key.  Look at the illustration from Continental on their tires below:


In this area the benefit is relative to the size of the rim you are riding.   While the current trend on rims is to go wider, there are still those out there running thin 19mm< aluminum rims.  If you were to run a 25mm on a 19mm rim, the tire would bulge creating more aero drag than necessary.  In this case, running a 23mm tire would be more beneficial.  When using a wider (most newer rims are) rim of 21mm or more, the tire sidewalls will sit flush on the rim making it more aerodynamic and adding to the overall benefit of the 25mm tire.


While 25mm tires seem to outperform the 23mm tire in almost every area there is still a place for 23mm tires.  More at home during Time Trials or for those doing very short intense efforts where weight savings might be a priority over comfort, rolling resistance and traction.
For most of us however, the 25mm simply delivers more benefits.  It is more comfortable, it has lower rolling resistance and better traction compared to the same tire in 23mm.

Specialized saddles, which one is right for you?

Specialized Saddles, what kind of saddle is right for you?

Riding a bike is one of the most fun and entertaining ways to exercise.  There are several factors that contribute to the enjoyment of a ride.  Performance, efficiency and comfort.  We will focus on comfort this time around, specifically on saddles.

When it comes to having a comfortable ride contact points are key.  Contact points include handlebar / grips, pedals, and saddle.  There are several saddles for different purposes and types of riders.  Mind that saddles are a very personal thing and by no means there is a one size fits all type of saddle.

There are several ways to determine a saddle that might be a good fit.  Here we will talk about Specialized saddles and give you some pointers to help you determine which one might be right for you.

Clinchers, Tubeless, Cleats... Hats?


We are always looking for ways to improve our rides.  Performance Tires can make a huge difference at a relatively low price.   This makes them great value when it comes to performance upgrades.  Here are key differences on Tubeless vs Clinchers.




If you are a fan of expensive super cars you know that Pirelli makes some of the best rubber out there.  They have decided to come back into the Bicycle market with their New Pirelli P Zero Velo tires.  The P Zero Velo comes in three models:

  • P Zero Velo – The All Around tire.  Light at 210gr and fast.  Sizes: 23C, 25C and 28C
  • P Zero Velo TT – The Ultrahigh performance tire.  Incredibly light at 165gr with the lowest rolling resistance. Sizes: 23C
  • P Zero Velo 4S – The All-season tire with great puncture resistance.  Sizes: 23C, 25C, 28C


Clipless shoes and pedals can really improve your riding. It increases efficiency and helps you put down more power. However, a worn-out cleat could be dangerous and even slow you down. You should make sure that you are replacing your cleats periodically. Check for signs of wear, especially if you walk on them frequently.

  • Risk of Falling– If the grips on the cleats are worn out it can cause the cleats to be slippery which may cause a fall.
  • Undesired Float - Worn out cleats can decrease or increase your float which can alter the efficiency of your pedal stroke and lead to poor fit possibly causing an injury.   It can also lead to the cleats getting stuck and you won’t be able to unclip.
  • Accidental Unclip - A worn out engagement tab (lip in the rear of the cleat) can lead to the cleat not hooking up to the pedals properly.  This can cause an accident if you are pedaling under power and the shoe disengages.
  • Inability to clip in - A worn-out cleat can also make it much harder to clip into the pedal, making it dangerous in certain circumstances like when riding around vehicular traffic or the start of a race.

Cleat placement is just as important as the condition it’s in.  Come see our fitting experts and make sure you are getting the most out of your cleats and pedals.
