SKS Bluemels Mudguards Fitting Instructions

You bought bicycle mudguards SKS Bluemels, opened the fitting instruction and were horrified by the fact that this “instruction” is difficult to understand? I understand you, I myself ran into this situation. But after some time I found a great way to install the SKS Bluemels mudguards and now I want to share this method with you to save your time and nerves.

However, on bicycles with a different type of brakes, the installation of mudguards may be slightly different. It’s also possible that your SKS mudguards may have slightly different mounts. On the packaging of my SKS Bluemels mudguards was written “New version”, on older versions, end caps and possibly other fastenings may be slightly different. But you will get the idea about how to install SKS mudguards and easily cope with the SKS Bluemels installation.

SKS Bluemels Mudguards Fitting: Necessary Tools

To install SKS Bluemels Mudguards you will need several tools:

If you have a hacksaw, you can use it for the last steps, but if you do not have a hacksaw or dremel, then I recommend you to buy a dremel/rotary tool. Dremel is not so expensive and will be a very useful tool for many tasks. With the help of it, you can saw, drill, polish and sand.

You can use it to cut bicycle brake cables, for polishing some parts, and for easy installation of SKS mudguards. Also, for this tool, there are many applications in your home (for example, polishing jewelry or creating a DIY charger for a dynamo hub).

If you use V-brakes or disc brakes, then take 2 washers, 1 nut, and 1 long sized bolt. If you use cantilever brakes, then the bolt that fastens your brake to the fork should be used for fastening the mudguard. Take the front mudguard and install it as shown in the photo below.

When installing the SKS Bluemels mudguards, you can use any bolt from the kit. They do not have a specific purpose and therefore you can use the one that fits.

Now take these nuts and combine them.

Next step, take the nuts and insert them into the mount of the SKS Bluemels mudguard.

Now take the front mudguard v-stays and put it into the nuts.

Now screw the bolt of the v-stays. Tighten it slightly. Because later it will be necessary to disassemble all this.

Do the same on the other side. If you have disc brakes or if its mount interferes with the installation of v-stays (as in my case), then you will need the plastic washers that are included with the SKS Bluemels mudguards.

When you are done installing v-stays, adjust the height of the mudguard (clearance between tire and mudguard). Choose the height that you like, but do not place the mudguard too close to the tire. Tighten the nuts.

SKS Bluemels Mudguards Fitting: Cutting Mudguard Stays

Now it’s time to cut SKS mudguard stays. But at first, I want to answer the possible question: “What happens if you do not cut off the stays of SKS mudguards?”

In the case of the front mudguard, there is a possibility that in case of an unsuccessful fall you may be injured by the sharp edges of the stays. But this can be avoided by slightly modifying the plastic caps. But most likely, you will still encounter a toe overlap. At first, I did not cut off the stays, I went riding a bike and sometimes, I began to touch the edges of the stays with my feet.

With the rear mudguard, there will be no problems, but it’s still better to cut off the extra length of stays. However, if you do not want to cut off the stays, then you can modify the plastic caps. You need to cut off the ring and put the plastic cap on the stays.

But let’s go back to how to cut off the mudguard stays. Take the CD/DVD marker and put a mark on the v-stays and on the mount as shown in the photo. Do this on both v-stays.

Now you have to remove all mudguard stays. After you remove the mudguard stays, you need to take a ruler or caliper and a CD/DVD marker and put a mark 16 mm higher than the 1st mark. Do this for both stays. The top mark is the place where you need to cut.

It’s time for cutting. If you are wondering – which tool is the best for cutting off the mudguard stays, then the answer is – dremel. Dremel provides faster, easier and precise cut. But if you don’t have a dremel and don’t want to buy it, then you can use a hacksaw. You need to cut the top markup.

Done. Now you can start the final assembly.

This time we will need an extra part – washer. It is necessary in order to protect the plastic of the mudguard stays when you tighten the bolt.

Insert the nuts into the mount of the mudguards.

Now insert the mudguard stays into nuts. But do not tighten them or it will be difficult to put on protective caps later.

Tighten the bolt.

Now it should look like this.

Put the SKS plastic end caps on the stays. Slide the ring to the side (as shown in the photo below). Then align the height of the stays with respect to the mark on the mount, as shown in the photo above. Then tighten the nuts. Finally, put the ring of the SKS end cap on the nut.

Then do the same on the other side. Do not forget about the washer when you tighten the bolt on the other side.

Installation of the SKS Bluemels front mudguard is done.

SKS Bluemels Mudguards Fitting: Rear Mudguard

Remove the rear wheel from the frame. Then take the SKS Bridge and slide the rear mudguard into it.

After, you need to attach it to the upper mount on the bicycle frame. In my case, I have run out of the required length of bolts from the kit. I had to look for an additional M5 bolt.

To fasten the SKS bridge to the frame, two washers must be used. One will be in front of the plastic mount to protect the plastic from a damage. The second washer will lean against the frame since the nut engagement area is small and paint may be damaged at the attachment point. And even a dent on the frame is possible, especially on thin Cro-mo tubes if you tight it strongly.

Now you need to fix the lower mount of the mudguard. In the kit with mudguard, there is some “incomprehensible” mount for that task, but its reliability is in doubt, so it’s best to use a good old bolt, washers, and a nut. But this time one of the washers will be rectangular. It comes complete with an SKS Bluemels mudguard.

During the installation, you will need the pliers, hold the nut with the pliers, and begin to tighten the bolt using the hex wrench 4mm. This is how it should look after.

Almost done. Now install the rear wheel back and start installing the mudguard stays.

A couple of points about which you should know when installing the rear SKS mudguard. Steel washers for the rear mudguard stays are optional since the stays are made of metal and if you will use a steel washer, the bolt can become either too long or too short.

On some bicycle frames, depending on the mount for the mudguard, the bolt can get out too much and begin to hit the bicycle chain and cassette. (See photo below).

SKS Bluemels Mudguards: Big Problem

In this case, you need to take special (included) plastic washer and install it as shown below. If you installed a plastic washer on the drive side, then it is desirable to install it on the other side (on the non-drive side).

Next, repeat all the steps to prepare the stays for cutting, as described above for the front mudguard. The rules are the same – adjust the mudguard to the desired height, then make a mark on a mudguard stays with a marker, then make another mark at 16 mm higher. Then take a dremel or a hacksaw and cut off the top mark.

After cutting the mudguard stays, start assembling everything back. The remaining mark is for easier installation.
