Fichtel & Sachs, Sachs and SRAM are the same series of hubs, shown together. This page covers all-derailer systems, and the more common internal-gear hubs. The SRAM/Sachs 3 x 7, 3 x 8 and 3 x 9 and the Sturmey-Archer CS- RF3 and CS-RK3 are the only production internal-gear hubs designed to use rear sprocket clusters. but other models are included in the list for the benefit of tinkerers -- see discussion.

Thunderbird Energetica. Best Road Wheel Upgrades. By Cycling Plus | Tuesday, July 24, 2012 7.00am A wheel upgrade is a great way to elevate an entry-level bike Philip Sowels/Future Publishing View Thumbnail Gallery Assuming you have a decent frame, wheels are the most effective upgrade you can make, offering the greatest real-world gains in any chosen area, whether you want to achieve an aerodynamic advantage, climb faster, increase comfort or decrease weight. For this test, we chose 16 sets of wheels that would make an ideal first upgrade over those supplied with many entry-level machines. If you’re aiming to race, commute, crack your first century or just get more from your riding, there’s sure to be something here to suit your needs. The majority have aerodynamic features, with a variety of rim depths, aero spokes and wind-cheating hubs, and alongside these generally narrow wheels are some wider rim designs, claiming to offer increased stability, comfort and durability.

If you were to catalog the riding apparel choices here at the office, overwhelmingly, you would tally Castelli's Body Paint 2.0 over any other pair of bib shorts. That's why we teamed up with Castelli to make two exclusive color options with the Body Paint 2.0 Limited Edition Bib Shorts. Now, we're combining our love for quality bib shorts, bright fluo, and Italian cycling and sharing it with you. Get 'em while you can. Castelli's Body Paint 2.0 is a moving revolution that was fast enough for Castelli to patent the design. It feels as it sounds, like a barely-there skin layer that's been painted on. Furthering this attribute is the bib shorts' nearly seamless construction. This brings us to the shorts' aerodynamic benefits. Interestingly, the leg grippers aren't actually grippers.

Rounding off the shorts are Castelli's most innovative chamois, the Progetto X2 Air. Assos T FI.Mille_S5 longLeg Bib Shorts. The Assos FI.Mille A.360 bib short was a mainstay of the Assos apparel line for nearly a decade. It was always known as their "Long Distance Short", and in the revamped version here known as the FI Mille S5, this essence remains the same. Why "Long Distance"? It's for two key reasons: First off, the FI.Mille S5 provides more stretch and less compression than the FI.13 S5. This is due to both the fabric selection, the cutting lines of the fabric, and the number of total panels of fabric. The other "Long Distance" characteristic of the FI.Mille S5 is its unique chamois. The FI.Mille S5 makes strategic use of A430 fabric to wick sweat and elastic fabric to reduce genital pressure.

The FI.Mille S5 is available 5 colors, in sizes Small-TIR. Giordana FormaRed Carbon Men's Bib Shorts. If you asked us the last time that we'd seen a pair of bib shorts which featured six separate fabrics in their construction, you'd be looking at our blank stares. However, the Giordana FormaRed Carbon Bib Shorts are made with just that amount. But, don't think that Giordana is simply adding fabric for fabric's sake. Instead, the materials are specifically placed in order to continue the FormaRed Carbon's dominance as one of the best feeling, and certainly best fitting, bib shorts ever created.

Starting with the bulk of the shorts' construction, Giordana went with its compressive HC-44 fabric. With a nylon/Lycra composition weight of 180g/m2, the FormaRed Carbon (FRC) bib shorts take on a nearly medical compression level (240g/m2). Moving to the inner legs and seat panel, Giordana placed an even stronger fabric called Zaffiro. As for the fit, the FRC benefits from Giordana's innovative contoured cut. Louis Garneau Course Superleggera Bib Shorts. Nothing creates tension between you and your bike like an ill-fitting, uncomfortable pair of bib shorts. Well, perhaps nothing except sweltering summer heat. The Louis Garneau Course Superleggera Bib Shorts are half of Garneau's premier hot-weather ensemble.

With effort-prolonging support, breathability, and a superb chamois, they ensure that you and your bike meld in harmony no matter how many miles you tack on as the mercury rises. Eight panels make up the short portion of the Course Superleggera bib shorts. This multi-panel construction allows for a precise, anatomic fit, as well as a strategic use of Garneau's Lycra Power, Delfino, and Lazer Rev fabrics.

Garneau constructed the uppers of the Course Superleggera out of Power Mesh and Carbon X-Mesh fabrics-- using Power Mesh for the lower and back portions, and Carbon X-Mesh for the shoulder straps themselves. For further comfort, the bib shorts feature Louis Garneau's own, patent-pending 5 Motion chamois. Capo Piancavallo Bib Shorts. Situated high in the Apennines sits the notorious Piancavallo ascent. Just shy of 14 kilometers, and with an average gradient around eight percent, the Piancavallo has proven itself as a battle ground of the Giro -- most notably for the epic battle between Pantani and Tonkov in '98.

Suitably, the Italian-centric Capo has devoted a 'collezione' based on this storied parcours, with the first piece being the Competitive Cyclist-exclusive Piancavallo Bib Shorts. Capo designed the Piancavallo bib shorts around the venerable Power Lycra fabric. This patented material expresses measurable results within the fields of muscle fatigue and proprioception. And not to be upstaged by tinfoil metrics, Power Lycra also reflects a powerful moisture management capability. Just as importantly as Power Lycra's attributes are its characteristics of fit. For the chamois, Capo went with the illustrious Elastic Interface Technology (EIT) D4 insert. OAKLEY JAWBONE SUNGLASSES at AtoZEyewear.com.

Split it up and do pieces as your schedule allows. Feel free to ask questions. I am at rox@cyclingsite.com Before you begin this lesson you need to count the teeth on each gear – both front and rear – on your bike.

First let's agree on some terms: A "gear" is a wheel with teeth that mesh with another gear or a chain. A "T" stands for teeth. The gears on the front by the pedals are usually called "chainrings". If you fasten several rear gears together it becomes a "cassette". Technically, a "cog" or "sprocket" is just the tooth on the gear, but those terms are often used to indicate the whole gear. The "shifters" are those things (usually on the handlebars) you move to change gears. The "front derailleur" is the little gadget down by the chainrings that nudges the chain back and forth from one chainring to another when you shift. Getting your gear inch numbers Back to work...

Smith PivLock V2 Max Sunglasses from Backcountry. We've come a long way since the days of the massive Oakley Eyeshade, made famous by Andy Hampsten as he triumphed over Mother Nature's frightful wrath during the 1988 Giro d'Italia. Granted, his fateful trip over the Gavia Pass couldn't have been done with much less than a full goggle like the Eyeshade.

But under more palatable riding conditions, the Eyeshades fogged too easily, and weren't compatible with then-evolving helmet technology. The same necessity for maximum coverage with minimum interference still exists today in the sunglasses we wear, but luckily, our modern shield lenses have advanced a great deal since '88. The Pivlock V2 Max from Smith is one such evolutionary leap. At first glance, the biggest difference between the new V2 and the first-generation V90, is the absence of the split arms. The lens on the Pivlock V90 series is what Smith calls their Carbonic TLT. The entire sunglass is essentially three separate pieces that effortlessly snap on to the lens.

Ultra competitors may only get a few hours sleep between long days of riding. Long-distance cyclists, because of all the miles on the bike, place more stress on their bodies than most athletes. Sports Nutrition For Optimal Muscle Recovery A) Theory Extensive research with endurance athletes shows that nutrition during rides and afterwards for recovery has four components: 1) Replenishing fluids and replacing electrolytes 2) Replacing muscle glycogen 3) Rebuilding muscle protein 4) Reducing muscle and immune-system stress. “Drinking plain water is not as effective in maintaining fluid balance as drinking a sports drink.” Michelangelo Two Bike Gravity Stand Space Saving Bicycle Storage from PUBLIC.
