Dear MBT,
Maybe I’m just behind the times, but what is with all the hype about single speeds these days?
TL “Nelly” Nelson

While single speeds aren’t our particular area of expertise, we have heard positive feedback by many riders who claim that simplicity reigns supreme. In addition to far less tuning and set-up responsibility, single speeds make good training rigs as the lack of gear choices forces a rider into focusing on the terrain itself and relying upon momentum. Finally, it appears that a good deal of fun is involved in reliving memory of a simpler time. We here at MBT like to regress on occasion ourselves, but I don’t suspect you’ll find training wheels on our bikes any time soon.

Dear editors:
I just wanted to say that I read MBT every month and my favorite section is ASK MBT. My question is this: I get tired on even short rides, my riding friends say I need more carbohydrates and I read at running sites that fatigue is due to lack of protein. Which is it? Also should I drink energy drinks or water?
Cordially,
Adam

Adam:
In this case it’s not really a cut and dry right or wrong answer. Proteins and carbohydrates are both essential intake requirements (as are fats). Protein is required for many of the body’s metabolic functions and is consumed more rapidly when you ride. Likewise carbohydrates are stored in the muscles and are burned as fuel during intense exercise (such as riding). Both are essential to any activity, especially one as demanding as mountain biking.

Since you did not include facts such as your bodyweight, typical ride length, or type of terrain, it is impossible to say exactly how your individualized diet should be structured. Here is a helpful link to aid in establishing an Individualized Nutrition and Hydration Plan: http://www.powerbar.com/NutritionResource/ToolsArticles/ArticlesDetails.aspx?id=5E602F1C-B3B7-4D44-8D3D-D5D5F92ABA99

While energy bars are a good source of carbohydrates (and quality proteins in some instances) the same cannot be said for all energy drinks. While some are catered to replenishing electrolytes, sodium, and carbs, others are designed to provide a short term rush either through stimulants (such as caffeine) or high levels of sugar. The latter is certainly more destructive than it is beneficial as short energy bursts are usually followed by extreme losses in energy (crashes). Also sugar rich products can dehydrate rather then quench. If in doubt, H2O is always in fashion.
