Fender mounts

Bought universal plastic fenders and and they given me two sets of mounts for the strut, both are plastic.


Used this type mount and it sucks strut always gets out of place when bike falls (when standing on a stand and wind is too strong).




I feel if i install this second type mount it will just break it looks too fragile.



Is there metal mounts i can buy to use with strut that has to be cut in length to fit?

Yes, but. Here in the US we learned many years ago that the fixed length "Wald type" fender braces with a non adjustable length was rather lacking in fitting/tuning ability. No fender I've seen that uses braces has been perfectly fitted for intended tires out of the box. So everytime I've mounted a fender I've felt the need to tweak the fender's curve WRT the tire's as well as adjusted the fender's centering with the wheel's plane. Remember that frames and wheel placement WRT the eyes and bridges is all across the board placement wise. Having mounted many dozens of fenders and used fenders on my own bikes for decades a non adjustable fender is one to avoid.

Here's some fender aspects that I have developed opinions about- The less plastic in the fittings the better. I do prefer plastic laminate construction for the actual fender as metal is noisier and unless very well mounted and supported will crack, usually at the BB bridge. Brace adjustments at the fender end of the brace is easier to deal with then the P clamp type adjusters at the eyes (like image 1 has). More braces is better then fewer. Few shops, or home installers too, take the time, effort and hardware to mount a fender well. Lack of washers sandwiching brace ends and mid or BB mounting locations allow for loosening of hardware and cracking of the fenders from vibrations. Fender extensions often will scrape the ground if the bike is lifted and rolled on it's rear wheel, but most are removable. Textured fender surfaces inhibit the application of reflective tape. One bolt does one job, not really a fender issue but far to many frames have a single rear eye. If a rack and fender are to be used a single bolt needs to handle both. Poor design IMO.

There are more but these are the biggies. I'll just repeat that more braces keep the fender better located and reduce the rear fender's bounce and thus cracking over time. But I got spoiled with first Blumels, then Esges and now SKS. The trendy Honjos and ilk I'll pass on.

Last bit is the OP's comments about banging on the fenders and expecting then to remain straight and rub free. Given the usual concern about weight and want of low cost I think this expectation is unrealistic. Andy

There's a reason for that.

If you must use a single bolt for a rack and a fender, the rack should go to the inside (against the frame) to minimize the bending stress on the bolt.

Never had issues with metal fenders that come with the bicycle, however my modern plastic fender (same brand as pictured in my first post) when i installed loosely it and took for test ride almost jammed my front wheel.

Problem is that U shaped metal strut that goes from the lower part of front fork into fender only mounts inside fender by some cheap plastic clip which got disconnected and the U-strut touched the tire that pulled it up towards top of the front fork where it got jammed almost locking my front wheel.

Since then i installed it properly and riding for about a year no problem. However i will secure U-strut more tightly with zip tie making hole trough the fender, even if it looks ghetto its safer.
