Mudguards without chainstay bridge, but...

[Boopop]

I do have that thread on the back of the seat tube. It's a Giant Contend SL1 2021 ( which I got very lightly used for £690, which I'm rather pleased about)

So my question is, can I just buy any seemingly compatible mudguards and the seat tube eyelet will act as the chainstay mudguard bridge on another bike? Or will I have to drill an extra hole in the rear mudguard? I've already got the mudguard bridge for the seat stays. I'm thinking of getting the M:Part Primoplastic mudguards, if anyone who can advise me what size I should get for a bike with 32mm max tyre clearance, that'd be much appreciated. Cheers and Merry Xmas

You need tough chromoplastic style guards
You have to drill them in the right place and use a stainless panhead machine screw. Allen heads protrude too much.
I would nibble down the end to fit between the stays ( tightly) , and make the tip a bit wider so it cant pop out.

And add a rubber gasket of some type between guard and sest tube to prevent rubbage.

do you have clearance for them ? from the photo it looks very tight.

My solution for a bike with no chainstay bridge:

If you get SKS guards like the above Bluemels, the clip will slide to wherever you need it. You could cut off the angled bracket and drill the middle for a flat headed screw, then bolt the clip to the seat tube, so you don't need to drill through the guard.

Drill were the hole is on the frame and just bolt on, as mentioned above a strong set of guards will be best.

Also these help to dampen any vibrations/rattling;
