Love running really low pressures? We review the CushCore Inner-Tyre Suspension System

by 0

When it comes to protecting your rim from damage while running low tyre pressures, CushCore is one of the best-known options on the market. To see just how tough it is, we got our local rim-dinger, David Hayward, to put them through the grinder as part of a tubeless insert group test. Over to David!

CushCore arrives as a very tidy box set, with two inserts contorted into it, along with a pair of special valves, instructions, and a whole bunch of rim stickers just in case you're feeling the Brand Loyalty… or perhaps are the kind of person who'd forget which wheels you put them in.

You can get CushCore inserts individually, or as a pair in a box as shown here.

The first thing that hit me about them was the very chemical smell, which has faded away over the months I've been using them. The second thing that stuck out was that CushCore inserts are moulded as a continuous closed band, so no need to mess around with Velcro or zip ties.

They're made for specific wheel sizes, and available for 26in, 27.5in or 29in wheels. At the sides, there are v-shaped grooves every so often to let sealant pass though.
