Reviews

Wedgie?

"I’ve had a problem with the bumper collar not lasting very long. It gets squished by the pins when extending then spreads the collar out and my post gets wedged and doesn’t want to raise. I’ve replaced the cap twice since I’ve owned it in 3 years. The first time they replaced it for free. Aside from getting water in my post when I wash my bike upside down this post has been amazing compared to others I’ve used."
