Got this Bridgestone Calmo size 22. Wheel size is 22 x 1.75 . My first on this wheel size. Luckily I had on reserved a stainless rim of this size that's why I didn't hesitate getting the bicycle. Here's the condition when I got the bicycle. Frame, rims, fenders, chain cover, and handlebar are all alloy. Single speed with front dynamo hub.
