|I am new to biking and just bought a cyclocross bike. My question is about gears. Am I supposed to use the lower cog gears with the bigger chain ring and the upper cog gears with the smaller chain ring. I have a 9 speed set up. Thanx|

|Avoid getting too crossed, i.e. using the smallest cogs witht the big ring, and visa versa. How much is too much? Depends on your system, it's age and condition, and the size of the rings/cogs you have. You can tell when you have gone to far as the shifting starts to get sticky, and you may get nasty noises. As a very general rule - keep out of the last 3rd each way round - 1-6 small ring, 3-9 big ring, but as I said, depends on your set-up.
Enjoy - M.

|Long week - avoid the big rear cogs with the big ring and the smallest with the small. You knew I meant that....|

must have been a coffee shot in there somewhere!
very funny muncher ;)
For Newbie: if completely new to biking, and just starting off with cyclocross - wow! that's a hard way to start!
For the fundamentals of gearing, learn how to read a gear chart - several books have them, like Greg LeMonds' book. You'll be able to familiarise yourself with gear inches and how they are measured out, ratios, gear combos, and percentages between gears.
As Muncher says, avoid what is called "crossover" - being in the big ring and the large cog (that would be the rear cog with the most teeth). Be careful when people talk about 'large gear' when in fact they me 'large cog'. Most roadies understand 'large gear' to mean cogs with fewer teeth. It can be damn confusing!

|it's this damn jacket with the straps and buckles - it's really hard typing with your nose, and sometimes it just takes all my concentration...
I'm on UK time, which means it's nearly the end of Friday, which is nearly the end of the week, which is nearly ride home time, which means that my mind wanders....

|I wouldn't bother with the gear ratio tables if I was just beginning to ride (in fact I still don't do, but that's me). The basic concept of gearing is pretty simple actually, you shift into a bigger gear and the going gets faster and tougher... smaller gear and you go slower & easier. And avoid the crossover.
For newbie: as a rule of thumb, I use the same as muncher, never get closer to the other end of the cogset than third or fourth cog. If you feel you need to shift into a bigger/smaller chainring.
