Does exactly what it is designed to do, at a very reasonable price
Needed a replacement seat post clamp in a hurry, this is bulkier and heavier than I'd like, but it does the job and didn't cost the earth
I have purchased this as a replacement for the pre-fitted bad quality clamp on my bicycle which bent under pressure. This is a good one, functions smoothly as expected. I recommend this to others searching for a good quality clamp.

Good
I am fully satisfied with the quality, fit and finish of the component.
Not recommended to buy it cant hold ur seat
Hello Hema chandra,
Thanks for taking the time out to give us your feedback.
We regret that you weren't satisfied with our product.
If i understand right, the seat-post isn't is slipping, you could try tightening the other side of the clamp and this will surely help as the hold would get better.
If I've misunderstood the issue, we would love to help solve the problem for you, and hence i request you to visit your closest store and our team will be more than happy to help.
Thank you!
Happy Riding

durable..does its job
No issues so far
My Riverside bike is used by my daughter too. For that I always had to carry my Allen key. Now this one is easy to operate to adjust height accordingly.
Can adjust our saddle without any tool.
The tightening nut is too small. Need a bigger one for better grip.
