Azonic Quick Release Seat Clamp
If your rig is decked out with Azonic components, then their quick release seat clamp is the cherry on top. Made from 7075 aluminum, it does the job with style just like all its Azonic brethren.
Had an entry level Haro I was building up / replacing parts. Clamp was a different color blue than advertised, and didn't work well at all, despite double-checking the size, etc. Seat would slip throughout the ride. Went back to stock clamp and never looked back.
The blue ano is more of a turquoise. It lasted a month of normal use on my wife's bike. The plastic spacer provided gets shredded fairly quickly. My wife has been using it for the last week without it and it requires more force when closing than she can apply. If you're looking for another clamp, I'd look elsewhere.
