I've been easing my wife into this whole cycling thing. At the beginning of the year she was riding a comfort bike with platform pedals. Step by step I moved her to clips and straps; then to an old road bike; then padded shorts and jerseys; then her new Fuji road bike. But she drew the line at clipless!
So we were hitting the thrift stores yesterday looking for props for a play my sons are in (and I'm looking for bikes or bike stuff) and I come across a pair of brand new Shimano SPD SL cycling shoes in my wife's size for $18. She tried them on and they were a perfect fit. When we got home I took a pair of M520s I had laying around and mounted them on her Fuji. I had a new set of cleats in my tool box so those were mounted on the shoes. We had ridden in the morning and she didn't feel like heading back out so the test ride would have to wait.
Got her up bright and early and had to practice clipping and unclipping a bunch of times. Once she was somewhat comfortable, we headed out. I rode behind her to keep an eye on her progress and she was doing great. Made several stops and she unclipped and clipped in fine. Then, she came to a stop and unclipped the right foot and leaned left. I was behind her and could only watch as she started to go down. At the last possible moment, she got her left foot out and down to catch herself.
Once her heart rate slowed a bit, we continued on for a leasurely 12 miles and she didn't have any more problems. When we returned home, she even admitted that clipless made the riding feel effortless. The transformation is complete. I think we'll have to get some pie!
