Don't sweat it man I will lol. chances are she will not even be riding this much this year because winter will be here soon and she's not an avid cyclist. I'm more shooting for next summer. But yes I only threw these tires on because I couldn't wait to sit on it and see how long the seat tube was and ride it around town and see what the gear shifted like. It's damn near the perfect size for her. She has a slight bend in her knee at the bottom of the pedal stroke and I could still go about 2 inches lower with my seat post. She sits nice and upright kind of reminds me of Peewee Herman lol! She went up and down the street on it and she said it felt nice
