Mudguard stay mountings
« on: 11 February, 2018, 02:09:00 pm »
Apologies if this is covered elsewhere - I couldn't find the answer.

I have the SKS type chromoplastic guards on my 20/26 recumbent ( A Performer) running Marathon Racers, and not over-inflated to give me a slightly less harsh ride.

I seem to break a stay bracket every year, and I'm running out of old guards to scavenge for spare brackets.  Anyone know if there's a bracket separately available that will do the job?

The part I need is the stainless strip that curves across the inside of the guard, bolts or rivets onto the guard and provides the mounts for the bolts that hold the stays at the edge of the guard.

It's the rear that always breaks, and I have three stays either side, so it's not the guard thrashing about excessively, but metal fatigue arising from vibrations from riding on the rural cart tracks that masquerade as the surfaced and classified roads that I've paid income tax over the years to help provide.

I'm handy at fabricating GRP parts for my model aeroplanes, so may have to resort to that if no-one knows of a solution.

Those can be bought separately, as I have done so in the past. Only ever saw them at one webshop though.

I have made thicker, better brackets in stainless steel for this job. It wasn't difficult to do. Some other thoughts

- an LBS may be able to help; they chuck broken mudguards with intact brackets away all the time

- some damping in the system may help; for example use small nylocks to secure the new brackets, and sandwich them to the mudguard via a layer of rubber.

- It helps if the stays are not elastically strained to be in the right place. If you have not already done this, give the stays a 'set' so that they want to sit in the right place rather than being sprung into position by the brackets themselves.

cheers

SKS replacements are widely available, e.g https://www.edinburghbicycle.com/sks-mudguard-bridge.html (a search for "SKS Mudguard Bridge" will bring up lots of hits).

I actually prefer the plastic ones (as fitted to Tortec and various other mudguard brands) - this kind of thing:

Thx, but it's not the bridge I'm after - it's the stay mount that goes under the guard.

Ah, sorry (looking at things on too small a screen!). :facepalm: I've yet to break that bit, it's normally the bridges that go on mine!
