Tips & Tricks: Get the Most Out of Your Bike – Get it Fit!

Getting the most out of you bike requires a lot of work and effort. Part of that work is performing regular maintenance of your bike like lubing the chain, checking and pumping the tires, washing the bike and having your favorite mechanic check the bike once or twice a year.

Beyond your regular tuning, the best thing you can do to get the most out of your bike and to help prevent injury due to bad form is to get your bike properly fit. A bike fitting is more than just setting your seatpost at the right height, it’s about putting your bike in the correct place for you to get the most efficiency out of each peddle stroke, alleviate any muscle soreness you are experiencing and help to prevent future injury. While bike fittings are important for all types of riders, road bikers benefit the most from a professional fitting.

Riders for top teams like HTC-Highroad, Saxo-Bank and Garmin-Cervelo have their bikes professionally fit by the manufacturers (Specialized using BG Fit for the first two, Cervelo for the latter) for not only power, efficiency and injury prevention, but also for aerodynamics on the time trial bikes.

For those of us not-so-professional riders, the best person to fit your bike is someone trained in the science of bike fitting and skilled in the art.

The many aspects of a true bike fitting include: type of bike (pure racer, endurance, touring or aero), frame size (including top tube length, seat tube height and stand over height), bar width, drop length, stem length, stem angle, bar angle, gear lever placement, type of seat, seat post height, seat position (fore and aft), foot position at mid-stroke and knee angle at the bottom of the peddle stroke. A skilled bike fitter can make all of these angles and interactions not only work for you, but make each peddle stroke more efficient, more powerful and more comfortable for the rider.

When you get your first road bike, you may be uncomfortable with the typical 45 degree angle position, especially if you just transitioned from a hybrid or mountain bike. So the fit of your bike can change depending on your comfort level with a road bike and your skill level. You will notice changes in the seat post height or stem length immediately after they are changed. But as you progress in your riding you will appreciate the subtle changes like fore and aft positioning of the seat and handle bar angle just as much.

Both of us have had our bikes since we began road biking just over a year ago. Miko’s initial bike fitting was designed to make her comfortable in her transition from a hybrid to a road bike. Her seat post was a bit lower, her stem was angled up and the seat was closer to the stem. The design of her endurance road bike allowed it to take on the hybridesq fitting, while still giving her the road bike experience. This was the right fit for her at the time.

After over a year of riding and minor adjustments to her seat height, Miko was ready for an updated fitting. We took Ruby into A Bicycle Odyssey to have Tony perform an updated fitting. He took her measurements on the bike and checked the handlebar width. He started with adjustments to the seat post height, flipped the stem changing it from an upward angle to almost flat, ensured her handle bars and hoods were positioned such that her back made a 45 degree angle with her bike in the hoods and her elbows slightly bent, while ensuring he back was almost flat in the drops.

The positioning change made the saddle uncomfortable, so after trying a few different saddles, a new one that matched her positioned was installed. The seat position from the stem was adjusted to reduce chafing in this new position. Finally, all of the angles were one again checked to ensure maximum efficiency. During the first ride she commented she felt she owned a new bicycle.

Jon purchased his first road bike from A Bicycle Odyssey. Part of the purchase price includes a fit by Tony. Transitioning directly from a hybrid bike is a huge change in position, control and speed. On his test ride, the bike felt like a great fit, except for the reach, which was a bit long. During Jon’s fit, Tony swapped the stem with one 10mm shorter. He then continued with a full fitting of the bike as described above. The Result: an amazing and efficient ride that allows Jon to ride long distances without pain, or go for short, hard rides without his back and knees paying the price the next day. ¬†When Jon got his second road bike, he made sure to also have a fit done.

Whether you are a beginner or an experienced cyclist, a good fitting can help you improve your cycling, help reduce pain you experience while cycling and make riding a more enjoyable experience.

Tips & Tricks: Riding in the Rays: Sun Protection While Cycling

Sun damage and wrinkles are never attractive, on or off the bike. Excluding beach vacations, cycling can easily be when we are most vulnerable to UV rays, as anyone who’s ever had a bad case of “sunglass tan” after riding would agree. We don’t cycle inside a toaster, so just because there’s cloud cover and cool temperatures don’t assume you won’t get burned. What you don’t see can hurt you.


For the face it is not essential that sunscreen be sweat or waterproof, as all sunscreen should be reapplied just as frequently: approximately every two hours, especially on an area where you perspire heavily. Waterproof creams and lotions can feel sticky, waxy and cause breakouts. Instead chose something comfortable that suits your skin type, is portable and easy to reapply. Sunscreen for the face and body are formulated differently and should be separate, just like soap – yes, gentlemen there is a distinction.

Neutrogena Ultra Sheer Liquid Daily Sunblock SPF 70 has a lightweight formula that absorbs instantly without the telltale white residue left behind by conventional sunscreens with zinc oxide. It’s possible to layer small amounts along your ride without creating cakey build up and in a 1.4OZ bottle will barely make a dent in your back pocket.

Powder Sunscreen like Colore Science Pro Sunforgettable SPF 30 contains titanium dioxide, preferred by dermatologists because unlike chemical sunscreens it creates a physical barrier to the sun’s rays. A light coating of this super fine, water resistant powder stays put without the heavy load of waterproof lotions and is an excellent choice for oily and acne prone skin. The skin toned powder also buffs the complexion when applied with the brush applicator, especially handy when there’s no sink and soap available as it’s possible to reapply sunscreen without the potential of speeding grime or bacteria on the face from your hands.

The two kinds of products can used together for more complete protection.


Outside the obvious health benefits of wearing sunscreen, like preventing skin cancer, “cyclist’s tan” (a kin to farmer’s tan but derived from cumulative tannings in jerseys and shammy shorts) is never sexy at the beach or in the bedroom.

Sports oriented, spray-on sunscreens are easy, expedient and thorough. Avoid choosing a formula so bent on waterproofing that it coats like acrylic paint. Like shampoo it’s not about how much you use but about covering every area.

Look for products like Neutrogena Ultimate Sport SPF 100 that mists on in a fine spray, coats evenly using an effortless trigger, smells pleasant and leaves skin feeling soft. Always spray before you dress but after you butter up and be sure to air dry. You might want to close the blinds.

Scientists stress that there is no improvement in protection beyond SPF 30, yet manufacturers continue to make products up to SPF 100 because people are seduced by the allure of more protection even at greater costs. From personal experience, when forgetful about reapplication these higher protection factors seem to be more forgiving and the fairer skinned swear by it.

Ultimately if a product you like has an SPF of 30 you will be adequately protected.


For those who want to avoid a sticky mess altogether, protective clothing with built in SPF is the best alternative. Arm sleeves with SPF, which fit like arm warmers but are lightweight and moisture wicking, like Gore Bike Wear OZON III SPF 50 Arm Protectors and Louis Garneau Matrix Arm Sleeve 50 UPF/SPF provide sun protection that unlike sunscreen on skin won’t wear off no matter how long the ride. Trendy, fashion oriented alternatives are made by companies like Canari for women.

However, these need to feel comfortable enough to wear for the duration of the ride without any sun protection underneath as a backup. Even though they are designed to keep you feeling cool, on a really hot day arm warmers aren’t intuitive for everyone.

Cyclists who want to eliminate the day-long discomfort of pinching from arm sleeves may prefer long sleeve Under Armour Heat Gear shirts with 30 UPF/SPF especially in the winter, which worn underneath jerseys provide an added layer of warmth using a high tech fabric that also wicks sweat away. These multipurpose shirts are a great investment when you can use them for other outdoor activities like running, hiking and skiing.

While not a replacement for facial sunscreen, used as added protection (and to accent your getup), cycling caps or visors fit nicely underneath helmets and the bill provides shade for the face without obstructing your view. Caps mask dreaded helmet head after riding in a way that’s stylish and wearing these caps in general makes a fashion statement that embraces bike culture whether or not you’re riding. HOWEVER, caps do not replace helmets. Shielding your face from the harmful rays of the sun means nothing if your brains are scattered across the road.


Skin cancer is the most common form of cancer, accounting for half of all cancers in the US. In the US alone 68,130 died from Melanoma in 2010 compared to 630 bike fatalities on the road in 2009, most likely without a helmet. Considering the lengths we’ll go to as cyclists to steer ourselves out of danger and fight for our rights in traffic, why wouldn’t we take care of matters in our own backyard to save our skin?
