Purchased this for my wife's Specialized Como e-bike because it offers far better protection than the Kryptonite cable lock she was using. A surprisingly large lock makes it easy to properly secure to immovable objects. Lock mechanism is incredibly solid when engaged. Mounting to some frames may be an issue due to weight/size as was the case for my wife's small framed bike so I ended up carrying it in a small knapsack. I feel the sturdiness / ruggedness of this lock definitely would encourage bike thieves to find an easier target.
I had to go to a 5.5" Kryptonite lock as opposed the 7 inch version in order to fit the bracket and lock within my bike frame. While a 7" will give you a bit more wriggle room to lock your cycle to a secure object, the 5.5" functions very well. I have had no problems securing my bike properly with this smaller version.
Lock is very solidly constructed, weight is reasonable and lock mechanism makes for a very tight, secure fit. No lock is entirely fullproof, but this one most definitely requires some extra effort to defeat...enough to encourage a would be thief to move on to easier targets.
This lock is not going to protect your bike for very long, if not used in conjunction with a larger locking system.
But,if you want some piece of mind in situations where you would usually leave your bike unlocked, this lock is a great candidate. It's small and light and prefect for gas station resupplies and bathroom trips. For cafe and coffee stops.
My only issue is that the locking and unlocking function can feel a little stiff and sloppy. And there is a small learning curve to getting it to run smoothly.
I've had a couple sets of PDW metal fenders. My last set of 45mm fenders were a little too wide for the crown of my C3 so I went with the 37mm, which fits perfectly. Despite the specs, I'm running 32mm tires and the coverage is just fine. They've replaced the rubber flaps with plastic, which feels a little bit like a downgrade, but the plastic flaps are slightly longer and seem to provide better trailing coverage. I'm not sure how durable they will be, but so far they've been fine. Worst case I will replace with more sturdy flaps - easy enough to do with this design. Another thing that seems to have changed is the finish seems to be somehow more permeable than my previous fenders. Best way to describe it is the previous fenders would wash off really easy and these fenders seem to collect road grime a bit more. Not sure if that due to the paint - these fenders are black versus silver. Other than that, the fenders are super rigid, fairly light, and quiet. All that I'm looking for in a fender.
