What gears should I ride? How do I choose? “Hey, my buddy Joe rides a 38 and loves it, so I think I should get that.” Sound familiar? I’ve over heard that kind of conversation many times, and I’m amazed. It may be the Engineer in me — or it may be the Cycling Coach […]
There are always sides to a discussion involving tradition and emotion. So many arguments about the use of a single front chainring versus a double or triple. In this case, tradition has generally stood with a single front chainring for single speed bikes (think kids bikes), city type bikes, and the “grandma” bikes with multi-speed […]
Do a search on the web for “Junior Gearing Restrictions” and you’ll find a bunch of sites that either explain the rules, or bash them. We’ve certainly heard the arguments by many eloquent authors that enumerate the virtues or expound the vices. This post, on the other hand, is intended to deal with the technical […]
In the bicycle industry we hear about “Anodized” aluminum frequently. In fact most aluminum parts of any bicycle are either anodized or painted to protect them from the elements and to protect us from the amorphous aluminum oxide layer that naturally occurs when aluminum is exposed to oxygen. Not all “Anodize” processes are equal, however. […]
What is BCD? BCD is an acronym for Bolt Circle Diameter. It’s the measurement (diameter) of an imaginary circle passing through the centers of all the bolts in a round pattern – like chainring bolts that hold the rings to the crank. On some cranks, like 4 bolt cranks, it’s fairly easy to measure, but […]
In the arena of challenges for front shifting, there are several fun and interesting bicycle categories — like multi-rider bikes (tandems, (what do you call a bicycle for 3?), Quads, Quints, …) recumbents and tricycles. Need a solution to a shifting challenge?
Worlds Fastest Shifting Chainrings! That’s a bold claim! With some cool technology and a lot of racing experience to back it up. Have a look at the business side (shifting side) of the chainrings in the pictures on this page, and note the special ramps. Those are not little bumps . . . Not single-point-of-contact […]
Put on the spot by a visitor to our booth at the 2013 UCI Masters World Cyclocross Championships, WickWerks engineer Eldon gives a brief introduction and explanation (along with a short demonstration) about how the WickWerks BRIDGE Shift Technology works. It’s a bit rough, considering it was an on the spot request and suddenly talking […]
