Description

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. Have more questions? Check out our additional instructions on how to measure your bike for Pitlocks.

Seat clamps are available in either silver or black, and come in five sizes: 28.6mm, 30.0mm, 31.8mm, 35.0mm, and 40.0mm.

    Quality is good and I think it will work out well… once I get the correct size. Follow the measuring instructions! I assumed too much, and it turns out I have an odd seat tube dimension. Looking forward to getting the right size installed.

    Ordered a few in the wrong size but finally got one that fits. Fast shipping and helpful people.

    Fantastic customer service with great email communication. Pitlock products are the best of their genre and nobody has a better selection in stock in North America. Highly recommended.

    I’ve searched for these for years. As far as I can tell, Urban Bike Tech is the only supplier in the Americas.
