Hi all,

I enjoy reading these boards and have found them very useful and interesting.

There is one thing though, that is constantly mentioned and i have no idea what you're all going on about!! That is gears, I hear loads about 27x30 and ratio this and that!!

Can someone explain what it all means please?

FWIW I ride a Trek 1.9 which has a Triple front ring and I think 10 gears on the rear.

I am quite new to all this and would relly appreciate the help
