Euclid never imagined this, I\’ll bet.
Way back in B.C., when Euclid was developing the principles of geometry, bicycles were undreamed of. Yet now we speak of frame geometry.
Choose your figure! Do you want a right triangle; or a parallelogram? Perhaps a trapezoid; or a pentagon? How about a circle??
All kidding aside, frame geometry is an important aspect of choosing a bicycle. If you want a bicycle to ride just for fun and exercise, it would be wise to avoid a racing bicycle with \”aggressive\” geometry. Such bicycles are apt to be too \”twitchy\” for the recreational rider. My own road bike is of the \”endurance\” variety. Gosh — Euclid never imagined this! If he had, bicycles might have been invented in his own day!
Any road bike feels twitchy for the rider new to road bikes. At any rate, mine sure did; and it took me several weeks to adjust to it. At first I did morning rides on the hybrid as usual; and I set aside some time in the evenings to work at getting used to the road bike.
It was rather frustrating to feel that I was back at square one. But taking it slow and easy while staying uninjured, and building confidence; is far better than trying to go too fast, too soon; and ending up in a cast.
And don\’t let your frame geometry run afoul of a hypotenuse — hey, wait, that\’s Pythagoras!
