Material of bash guard and which is best?

Bash guards are made and manufactured in many materials which include:

  • Steel
  • Aluminum
  • Plastic

When choosing a bash guard these things cause confusion that which one is best for my bike chain.

if you are thinking about the plastic material bash guard then experience and practical research say that plastic bash guards are the number one cool guards for a mountain bike.

the reason is that the main work of a bash guard is to protect the chain and chainring from hitting the lower bumps and earth surface, so when you have a sloppy trail and suddenly the central part of your bike got stuck with some old tree, rock, or any bump that may be poured rock, so in this case, both tires of the bike are touched with the earth surface and the bash guard is not hit with a larger force

the main function of a plastic bash guard is to provide protection this is the main reason that plastic bash guards are lesser in weight as compared to the steel and aluminum ones, but if you have got a hard terrain with unlimited bumps then upgrade your plastic bash guard with the steel one.

For hard and rocky trails steel bash guards are recommended because these are firm, and rigid as compared to the plastic bash guard because of their quick response to absorbing bumps arising from the center of your bike.

Aluminum bash guards are for easy trails like cross country and your own made trails with lesser bumps.

Installation of bash guard within the crank chain:

The bash guard contains a spacer, washers, nut bolts, and an instruction paper where you can see pictures of the chain guide and bash guard and their proper attachment method.

First of all, install the spacer in place of the leg pedal by removing the crank chain and pedal leg with the help of a torque wrench and Allen key. bash guard spacers differ in their type and their spacers are also different from each other, some have three places for nut bolts and some have just two places to tighten the nut bolts of the bash guard with the spacer.

After inserting the spacer within the pedal leg again install the pedal leg and crank chain, the spacer should be installed in such a way that the bolt holes of spacers should be placed in the top upward position.

Now take the bash guard and nut bolts, align the bash guard by pointing in the forward direction and insert the washers and bolts within the hole of the spacer and tight them with the Allen key, again check the bash guard if it is moving up and down then tight again by applying an extra force on the Allen key.

You can also install a bash guard without removing the pedal leg and crank chain, but it is a must to insert the spacer within the pedal leg which needs removing and uninstalling the pedal leg and crank chain.

Useful points to remember when installing bash guard:

The bash guard stays closer to the chain and chainring, always install the bash guard at a few distances away from the chain and chain guard, this distance should be 3 to 4 millimeters. it is necessary to keep this point in mind because a bash guard is a cheap thing and the chain and chainring are expensive materials of MTB, otherwise, the bash guard creates a risk factor of touching and rubbing with the chain which causes damage.

Bash guard creates direct contact with the earth’s surface, when hitting bumps of the terrain the nut bolts of the spacers become loose which needs to tighten again with the Allen key because it is a major problem bash guard will move forward and backward after hitting and it looses its actual position of installation, for this purpose always carry a small pocket Allen key with yourself to get rid of these types of small irritating problems.
