So this new lock called the Blackburn Folsom Compact came out and it features a hexagonal bar along with a dual bolt system while the Kryptonite Evolution Mini still has a single but it potentially could be of harder metal, it's also slightly smaller.
I can get the Folsom for $33 vs $40 for the Evolution.
I ride a 52cm track frame so I don't think size will be an issue for either. What do you guys think is better? My bike is worth about $250.
