Customer Reviews
I just fitted the jockey
wheels that I purchased from you, WOW!!!!!
I didn’t think they would make that much difference. Crisper sharper
gear changes and perfect alignment EXCELLENT+++++++ and my sister-in-law wants
them to wear out (hope that is a long time) to wear as ear rings!!!
Gary, U.K.
First ride today on the
new Omni ceramic pulleys-killer fast and smooth! Chain ring bolts fit perfectly
too and look sharp! Thanks for great items and communication! Matthew
I bought a set of the
Omni Racer Pulleys for my Foes FXR…I’m using the SRAM X9 derailleur. Man what
a difference!!!!I had my doubts at first but so much cleaner and crisper up and
down during shifting!!!
