## Description

Replaces unsuitable clamps with non-parallel clamping surfaces, or surfaces that are too small. These seat clamps are specifically designed to accept Pitlock seatpost skewers. Pitlock’s locking skewers are designed to work on flat, parallel surfaces. If your bike’s existing seat collar does not have flat surfaces to accept the skewer, you will need to replace the unsuitable clamp with one designed specifically by Pitlock. The standard-length Pitlock seatpost skewer (33mm) will fit any size Pitlock seatpost clamp/collar. To replace your existing seat clamp, measure the outside diameter of your seat tube.

    Doesn't ft, too narrow. "AVOID"
  

*by H***S on Reviewed in the United Kingdom on February 16, 2017*

It didn't fit, its too narrow for normal road bike, I wonder why the seller didn't include any product information in terms size.
