You must be an engineer.
Welcome to the forums.

You may find that 23 tooth a little small when you start climbing hills with legs that are 10 years older. If you are lucky enough to have no hills, there probably won't be a problem.

Just a suggestion here, technical observations, such as yours, are usually posted in the Mechanics Forum and may, or may not be moved by the moderators to that section. It will still be listed on the "New Posts' and be seen by most members.
