Which mudguards?

[kambites]

I want a set of mudguards for my Vitus Substance GRX. Its primary use is commuting so effectiveness at stopping spray is more important than clearance for dealing with large lumps of mud. The bike seems to have all of the eyelets except on the fork crown. Any suggestion for a brand/model of mud-guards for this setup?

It's currently on the original 700Cx37 tyres, but it would be nice to be able to fit slightly wider ones if I want to later without changing the mudguards again.


ETA: I will also be fitting a pannier rack, if that makes any difference.

I put some SKS Edge mudguards on my bike, they worked very well over the winter although I did have to make a small extender for the front.

[kambites]

I was looking at the SKS Edge. Do they come with the necessary bits to fit to a bike with no fork crown attachment point? I think I see a bolt head peaking out there on your bike so presumably you have one?

I think the term is a "steerer tube bung"?

I really rate Portland Design Works (https://ridepdw.com/collections/fenders?srsltid=AfmBOordU4TdcurZKJJIgOMNyiD2Cz5MzwX_dQafh6R280Rk5K9jqU6Y) which really are excellent. Nicely made and don't make a sound when fitted albeit they're not particularly cheap but I'd say totally worth it.

Actually maybe the hole on the bottom of the steerer tube is threaded, I need to get the wheel off so I can have a look.

SKS Speedrockers on mine. Once initially set up, 2 mins on & off.

This is the correct answer

[Dannbodge]

I use Portland Design Works ones on my winter bike.

Uber expensive but really really good quality. Luckily I picked them up off eBay for cheap

[InitialDave]

I use SKS mudguards on my hybrid, with extended splashguards from Raw on them. The "stealth" black reflective ones, which do what they say.

Kinesis Fend-Off are very similar to PDW and far cheaper. I'd get those.

I have sks bluemels on mine with 40mm tyres with room to spare.

Ah, sorry, I missed the bit about your missing crown hole!
I've checked all the fittings they came with and there isn't anything that would work for you without drilling or other extreme bodging.

No threaded hole in the back of the fork??

Nope. However, having had the wheel off, there does appear to be a threaded bung thing in the bottom of the steerer tube. It's bigger than the usual M5 though, I need to work out what size it is, then I can drill a hole in whatever mudguard I get and screw it on using that.

[Bill]

That's a pain. Not ideal as the screwhead will eat into tyre clearance.

True, but on the other hand the mudguard will be pulled tight against the crown rather than hung a mm or two below it; although I guess I'll want some sort of padding in the gap so it doesn't scratch the forks. A small strip of leather or something.

[Bill]

Maybe worth checking with the retailer before you get too into it. The spec says mudguard mounts so it's possible it's a manufacturing error.

[kambites]

I'm guessing that this threaded bung IS the mount. I can't imagine why else it would be there and from what I've read it's not an uncommon way to mount a mudguard to a carbon fork.

[InitialDave]

With a countersunk head screw and some care, you should be able to get it so the amount the screw intrudes into tyre clearance is no worse than the rivets used to attach the manufacturer's brackets to some mudguard designs anyway.

[kambites]

Yeah I think I can 3d print a spacer to fit neatly between the mud guard and fork, then buy some aluminium mudguards and hammer a recess into them to take a countersink bolt head. Should be able to make it pretty much perfectly flush.
