How To Fix Snapped Mudguards, The Cheap Way...


Recommended Posts

Sitting in the garage soldering some wires together I thought to my self "I wonder if this would melt plastic"

So I got an old sherco mudguard and cut the back bit off, I got the soldering iron and started to "fuse" both sides together, I did both sides and it seems like a good fix and seems quite strong.

so if you snap your mudguard keep the bits, this way means you can have a few (slightly ugly) but working spares.

I've used the soldering method quite a few times but mostly on road bikes (inside the panel where its not seen). Works fine but not very strong.

Be very wary of the fumes though ! Cyanide really isn't good for you !!!!

I've 'hinged' a few back mudguards or used tie wraps on past trials bikes (when I was skint), easy to fix when it breaks again !

I have welded neumerous fenders in the past some good some not so good. The real trick is to get the dirt out and to use the correct rod.

Specialty welders are pretty cheap too.

I have yet to find a modern trials bike that does not have a poly propylene fender. If you look on the underside for the markings cast into the remaining parts of the fenders you will probably find a date stamp and a material stamp. PP = poly propylene ABS = Butyle styrene PE = Polyethlene. Most of the time if its all the way broken across you need to add reinforcement under neath.
