I ride 2 different bikes to work, the electric from home when its not forecast to rain a lot and my mountain bike when it is raining, that one gets placed in the back of the truck and gets ridden a mile or so to allow free parking. Thats on rainy days. I have panniers for the locks, battery, lunch, rainsuit etc and I really don't want to carry my seat and post into the office as well. So I've been looking at methods to lock the seatpost in place and found one that looks to be promising. It's called saveyourseatlock , basically a version much like a quick release clamp for a seat that has a lock so you can't just open the clamp to remove the post and I was wondering if anyone hear has used this item. I read about cables and padlocks and really don't care for that style too much.
