Review on Kryptonite Evolution Integrated Chain Bicycle Sports & Fitness by Myron Lovro

Nice lock but there are a few things to know before or after you buy it. 1) Revain has a 5.25ft lock/chain listed as 5.25". 2) Don't press on the key as it's not the key that's sensitive, it's a link that goes into the locking bracket, try to keep it (the last link) straight (in the shackle) aligned but try not to press hard, otherwise the key will not turn. 3) This (5.25ft) is nice to have when there's nothing around except big trees to tie your bike to. 4) Krytonite rates this lock 8 out of 10 for security. 5) It rolls well under my seat when riding, but if I didn't have fenders (to keep it there) I don't know where I would put it on the bike because it's quite large.
