Should be renamed
As a tall and husky cyclist, at 220lbs, riding a modern full suspension bike, my seatpost protrudes approximately one kilometer from my bike. I've had a lot of problems with seatpost slippage.

I've already burned through two seatpost collars tightening them down as hard as I can, so I've moved on to looking for larger collars to use. The Surly collar is burlier than a lumberjack's burly beard.

My only regret is that I am tragically stupid and unable to order the right size for my bike, so I had to return it. I need a 35mm and I don't think they make one that big.

I bet it does the job like a mother, though. It's solid and has a huge screw, just like any prison shower.

Beefy!
Heavy duty, sturdy clamp! Fit perfectly and once it's tightened down your seat post isn't going anywhere! Not the best looking by any means but it does it's job and does it well!

PROS: Easy To Install, Durable

BEST USES: Upgrade, Casual Riding, Mountain Biking, BMX
