Mudguard Screws

[Jezston]

I'm having a SERIOUS problem with my mudguards and wondered if anyone might be able to offer some advice.

I have a pair of SKS Commuters on my Kona Dew:

The eyelets where you attach screws to set the height adjustment on my rear guard will NOT hold a screw (front is fine). I've had to take to carrying a bunch of nuts and bolts around with me because no matter how tight I've done them up by the end of the journey they'll be loose and rattling around.

Today was the final straw. After getting on the train after a 1/2 mile journey from my flat to the station, one of the screws, despite being fully tightened when I left the house, had GONE, meaning the mudguard was rubbing against the wheel. Cue brand new nut and bolt, tightened to buggery. By the time I done the 5 miles from the station to my work - GONE!

No idea why the screws in the front guard are fine - guessing the muck off the road has gunged them up preventing the nut from working loose!

I have been advised to get some 'nylon nuts' which shouldn't unscrew themselves from the vibrations of the road. Would anyone else be able to suggest anything?

I've never had a problem with my SKS bolts but maybe that's beacause mine are different. All I can suggest is you email sks and tell them about your problem and hoefully they'll pay for nylon bolts.

Nylock nuts should prevent this, although you could try some thread lock (nail varnish also works) on an existing bolt.

just scanned down that, so about 60 seconds and my sight is now fuzzy, are you trying to destroy peoples vision?

You could try some shakeproof washers.

I don't understand how people have problems with mudguards. I've had them on all my bikes for years and I've never had any problems fitting them or having them work loose.

No problems here either, but then the eyelets on my frame and fork are threaded and do not require nuts on my bolts...if they did I think I would nick borrow some of her nailvarnish to lock them.

Or do that, never actually seent the purpose of having mudguards. For all the expense and hassle I would rather buy a decent set of waterproofs.

I got them after doing a 12 mile through towpaths in the rain with a friend on a CX with mudguards. Myself and my bike were completely covered in mud and my friend and her bike were virtually spotless. And yes I was wearing waterproofs - but cleaning them is still a pain. And I had a train ride afterwards covered in muck. Cleaning method - getting in shower fully dressed then gradually undressing.

Has also resulted in far less maintanance issues with my bike since fitting them. Apart from issues with the mudguards themselves!

What happens should you ever wish to remove your mudguards?

I guess the superglue option might make it a bit tricky, but loctite or nail varnish will come apart fairly easily with a decent spanner on the nut.

Agree with both of those, and nail varnish.

If all else fails make sure there's a short piece of thread behind the nut and put Araldite on it. When you want them off it will crack off both steel and aluminium bolts if enough force is applied.

Sorry but your comments about mudguards on the Fnrttc website are clearly written by someone who's never had them properly fitted! Mudguards don't rattle, don't come loose, don't come off, do keep you and your bike clean, do reduce maintenance bills and transmission faults, weigh next to nothing, and don't slow you down.

(Or at least that's my experience from 100,000 miles or so riding with them fitted to my bike).

Next.

Loctite 222.

It is a low strength thread-lock. If you use a high strength Loctite, you will need a blowtorch to disassemble the screws. Seriously!

Yep agreed, I use superglue on my nuts and they are still firmly where I left them.

The mind boggles! Glad they are still where you left them, but, doesn't it hurt...!!

Quite right, but if you do use the wrong strength, not just for this, there is a fluid sold by the makers which softens the stuff to let you undo things - but it's expensive, of course.
