How to Tune Shimano Di2 From Your iPad or iPhone

Shimano has been in the electronic shifting game since Dura Ace 7970 was introduced in 2009.  Their E-Tube system debuted with Ultegra 6770 in 2012 and continues to be the standard in electronic shifting systems today.  You had to take your bike to a local bike shop that had an expensive adapter and computer program to tune the drivetrain and update firmware.

Since then, Shimano has released the E-Tube app for iOs.  By adding some Bluetooth Low Energy components to your drivetrain, you can update firmware and tune your shifting from your iPad.  It's never been easier to tune and update your Di2 system.

Click through the jump to learn what you need to use your iPad to tune your E-Tube Shimano Di2 system, including a video overview of the app and how to use it.

Solos Smart Cycling Glasses Review

Imagine riding in a tight pack, shoulder to shoulder with the rider next to you.  The group rides under the 1K to go banner at high speed, nervously shuffling as the finish line beckons.  You take a split second to look down at your power meter display to set yourself up for the sprint.  In that moment, the rider in front of you taps his brakes and you hit his rear wheel, crashing hard.

Next, imagine flying down a sinewy descent, carving sweeping turns with aplomb.  You glance down at your computer to get a speed check and miss the small pothole in the road in front of you.  Your front wheel hits the square edge and flats the tire, you lose control and crash.

The Solos Smart glasses aim to make those two scenarios a thing of the past.  By creating a pair of cycling glasses with an integrated heads-up display, Solos has put your most critical information right in front of your eyes.  You never have to look away from the road to check your power or speed.  Keeping your eyes on the road keeps you safer.

Do these $500 cycling glasses stack up to their price tag?  Click through the jump and I'll go in depth on the newly released Solos Cycling glasses.

Muscular Endurance Cycling Training With Zwift

Zwift has revolutionized the way we train indoors with a trainer.  The emergence of smart trainers has turned Zwift into an immersive virtual riding experience.  Muscular endurance (ME) is one of the basic fundamental skills that create a well-rounded cyclist, but it can be boring to accomplish on a trainer.  Combining the two together provides you the opportunity to get tons of high-quality training and keep things from getting stale.  But before you can go about building a ton of muscular endurance and making your body bulletproof, you have to understand what the goal of a ME interval is.

So, first of all, what is muscular endurance and why is it important?

Muscular endurance is your body's ability to resist muscular fatigue under pedaling tension.  That pedaling tension is where the magic happens in your pedal stroke.  The more tension in the pedals, the more power gets to the rear wheel and the faster you go.  I'm sure you've experienced a time when you have to really dig in and push hard to catch your riding buddy.  After a short time, your legs start to get heavy and tired and you have to rest.  The more times you have to repeat this kind of move, the harder it becomes because your legs are just tired out.  Maybe your legs cramp up or maybe you just can't make the move.  No matter what the outcome, you just need more ME training in your program.

In this article I'm going to give you tips to improve your muscular endurance training with Zwift.  Click through the jump to find out how:

Evaluating Ride Data and Race Data

With the huge number of electronic gadgets attached to a bike these days, it's inevitable that cyclists will be inundated with data.  From speed, cadence and heart rate to power data (and even new technologies such as muscle oxygenation data), there's a mind-boggling collection of numbers to consider. But why even bother collecting data? Evaluating ride data is one of the biggest reasons most cyclists collect data and it can tell you a lot about your ride if you know how to look at it the right way.

In this video, I'll walk through evaluating ride data from several race performances.  I'll describe what I look for and how you can use that information to improve your training and riding.

Zwift training is a hot new form of indoor training that has people excited.  In a nutshell, Zwift training allows you to sit on a trainer in your living room and ride in a virtual environment with people from all over the world who are doing the exact same thing.

How cool is that?

In previous videos, I discussed how to include some Fartlek training in your Zwift training sessions and how to use the new workout builder to create a custom workout in Zwift.  In this video, I'm going to explain and demonstrate how to roll a climb.  This kind of skill work is a perfect use of your Zwift training time because it's hard to understand how to execute it properly without being out on the road.  Fortunately, Zwift is the perfect virtual road to demonstrate on.
