Start by installing the correct size bash guard for your chainring size

The smallest guard fits 28-30t chain rings

The middle guard fits 32-34t chain rings

The biggest guard fits 36-38t chain rings

Tighten the fixing screws to 0.9N*m using a T25 Torx wrench

Start by opening upper slider

Open the metal clip on the upper slider

Flip the clip open

Release the latch and rotate the upper slider open

Loosen the lower slider bolt using a T25 Torx wrench

Pull the bolt out slightly and rotate the lower slider open

Remove cranks from the bike

Install the guide onto your frame or ISCG adapter (if one is needed) using the supplied T25 screws

It is recommended to use the longest screws possible to provide the strongest connection to the frame - two lengths are provided

Lightly tighten the screws until the backplate is snug against the frame

Slide the cranks back into the BB and re-install per manufacturer’s recommendations

Sight down the front of the guide to check if the guide is centered over the chain ring

If needed, use the provided ISCG05 C-spacers or washers to move the guide out from the frame until it is centered over the guide

It may be necessary to remove the cranks to adjust the guide. However, in many cases it is possible to reach a T25 torx wrench through the chain ring to tighten and loosen the ISCG mounting screws.

If using the C-spacers, removing the middle screw will make adjustments easier, just remember to replace it once you are satisfied with the guide placement!

When the guide is centered over the chain ring, rotate the guide such that the upper slider fixing bolt is in the 12 o’clock position

Tighten the ISCG mounting screws to 6N*m using a torque wrench

It may be necessary to adjust the lower armature to provide additional clearance for the lower slider on some bikes

Remove the two lower armature screws and relocate the lower armature as necessary

Tighten the two lower armature screws to 6N*m with a T25 Torx wrench

Install the chain onto the chain ring

Close the upper slider and clip the latch closed

Thread the chain over the lower roller

Rotate the lower slider closed

Position the lower slider such that the arrow is in line with the bottom of the chain and tighten the screw to 0.9N*m

As a final step, cycle the suspension thru the full amount of it's travel to ensure that the upper slider clears the chainstays. Most newer model trail/enduro bikes and some DH bikes will require the compact upper slider found on our TRS guide to achieve chainstay clearance.
