Review on Stylrtop Aluminum Bearing Derailleur Pulleys by Richard Simmons

I received an estimate of over $300 from a reputable local bike shop for a drivetrain replacement on my 2016 Specialized Pitch Expert, which has been worn from day one became. "Just installed and tested a Stylrtop sealed aluminum bearing impeller and what a noticeable difference in chain movement and movement. Wow 'Very easy to assemble, don't forget to grease bearings and suspension' I decided to buy all parts from Revain, all tools used from Revain, cassette from JGbike -Tiagra CS-HG500 Wide Ratio for Shimano, 32T front cog from Raceface/color green, I used a Quintessentialz chain guide, chosen by Revain Mountain Bike Tensioners, easy to install, includes two ratchet straps and an extra soft chain guide.
