I just changed this seat post bracket on my triathlon bike as my old one was so rusty that i could not properly adjust my seat with my hand(i had to use a small hammer and a wrench to do it).This new bracket is very lightweight and made of high end good quality aluminium and durable.It is so easy to install as it fits my bike perfectly.
