Good point. I had one of these in the 60’s. It must have been an older model street bike. The models I’ve seen today are either 3x7 or 3x8, not 2x5.
3x7-8 are typically cheap mountain bikes. The standards for road bikes are now 2x10 and 2x11. Yep, 11 gears on the cassette alone, with two up front.
My road bike is 2x9
