This is the second in a two-part account of my search for the perfect bike fit.
So far in this epic quest (which you can read about here), I discovered that my trusty Dawes did not fit me at all, that bike frame sizes bear very little relation to the size of the person riding them and that spending a large amount of money on a new bike is a lot easier when you have an expert telling you to.
Er, pardon, wood? Surely no-one makes bikes out of wood any more.
But, of course, they do. And not just the sorts of people that make dresses out of meat (fireplaces out of cheese, whatever…). Wood is an entirely viable, albeit unusual, material out of which you can fashion a bike.
This post is the fifth in a series that looks at frame materials, and how they are used to build bikes. If you missed any of the earlier ones, they can be found in the ‘Frame Materials’ section of my dedicated page: How To Build A Bike.
If you read my post about how bike gears work (if you didn’t, you can find it here), you may recall that I discovered that there was more to the subject than could be covered in a single outing.
It turns out (because, yes, sometimes I write these introductory sections AFTER I’ve written the body of a post), that there are many interesting things* that you can say about each of the components that form the drive train of a road bike.
(*Some interesting things. The occasional interesting thing.)
So today I lift the lid on the many and varied charms of chain rings. Enjoy…
Gears are a pretty fundamental part of the modern bicycle.
In fact, as the handlebar-moustache-sporting, Victorian gents amongst you will know, the introduction of gear rings and chains spelt the end for the Hi-wheel (the Penny Farthing to you and I) and other direct drive bicycles.
By varying the size of the chainring at the front and the sprockets (or cogs) at the back, cyclists could generate greater speeder without having to spin the pedals at ever-increasing RPMs (or balance precariously above gigantic front wheels).
In this post, I’m going to give an introduction to bike gears.
Since this is a blog about road cycling, I’ll stick to talking about derailleur gears (i.e. the ones seen on road bikes). Conveniently, this means I can avoid having to admit that I really don’t understand how hub gears work (what? ah…).
