The rear shock of your mountain bike has a crazy hard job on your bike, it handles all the abuse coming from the rear. Making an upgrade or replacement to your rear shock can have huge performance gains. MTB rear shock options to choose from are a bit overwhelming, but some of our favorite brands are Fox, RockShox, CaneCreek, Ohlins, Marzocchi, MRP, DVO and Push Industries. You have either the choice of a rear air shock or a rear coil shock from most of those brands as well as standard or metric shock sizing. From cross country to enduro to downhill, you have plenty of rear shock options to pick from so if you have any questions on what shock fits your bike or to go with an air or coil rear shock, please contact our customer service team to enquire about mountain bike rear shock replacement.
