Technology

Closeup image from behind and to the side, of Chainguard attatched to a Stanton MTB Frame.

Crescent Shaped Ridges

The ridges prevent chain links from catching, and reduces noise caused by chain slap.

Rockstop's Own Fitting System

The Ziggy Wraps and tabs are flat, stretchy, and do not cause any marking on the frame. The wraps can be easily fastened and removed. An extra wrap and tab comes with each Chainguard.

Sound Deadening Material

The tough polyurethane rubber has superior wear properties that resist chain damage, but is flexible enough to deaden the sound of chain slap and will fit to many chainstay shapes.

Fitting

The Tyre Insert comes ready assembled. To start fitting, we suggest fixing the first bead of your tyre onto the rim, then position the insert so that any hole is placed over your valve and feed the rest of the insert onto the rim before putting on the second bead. Check the beads are seated and then inflate. This should take around 5 minutes.

Your protector works! One happy boy!

It’s also really quiet, so good in fact that it’s made me notice all the other knocks on my bike! I forget it’s there while riding (probably a good thing!) and it’s really easy to clean after a ride, everything just washes right off.
