Mudguards won't fit!

bungle73

After sending the previous pair back because they were the wrong size I've got problems with the new pair. I just tried to get the back wheel back on, so that I could adjust the rear guard, and it won't fit! There's not enough space between the guard at the lower bridge and the tyre to get it through! The guards are supposed to accommodate up to 28 mm tyres, which is what I've got on!

More mudguard mayhem ?

The guards may well work with 28mm tyres but you have to have the frame clearances to do this.

What frame is it ? Do you have a picture of the clearance before the mudguard ?

bungle73

It's a Mango Point R, which is supposed to work with mudguards up to 28 mm tyres.

Yup, I suspect the guards will accommodate the tyres but your frame + guards won't.

Any scope for hacking away the offending bits of guard to allow the wheel in?

Are you pulling the rear mech as far back as it will go? (assuming it's a geared bike of course...)

25mm on here - obviously 28mm will have less clearance.

Is the mudguard as high up as possible ? Getting them set up right is a PITA from my experience.

bungle73

I think it might be because I used the wrong bolt to secure there. There is another packet with some gubbins in it, which is apparently for that purpose - I only know that because I just watched someone's YT video, the instructions are about as much use as a chocolate fireguard.. But the bolt they give you is nowhere long enough to to the job.....

Clearance for 28c tyres with mudguards or 32c without. Mounts for panniers and two water bottles.

High up as possible? How would that affect the lower bridge clearance?

fenix

Sorry - thought you were talking about the brake bridge - not the chain stay bridge.

Using the right bits will help you though....

I'm not even sure if that is the problem anyway - I'm just assuming it is. There is only a slight difference in bolt head size.

bungle73

The video I watched, the guy is talking about the bolt I'm having problems with, and saying it isn't long enough, and the next thing he cuts to where he's screwing it up, completely missing the part where he shows how he's doing it! Not much use. I can't see any way of securing it with the bolt provided - it's too short. Far too short.

fenix

where is this bolt going thru ? the Chainstay bridge ? Would a zip tie work ?

The mudguard makers don't know how thick your chainstay bridge is - too long would cause problems with clearances too.

keef66

I just fitted some Chromoplastics to a colleague's Datum. That's got discs, 32mm tyres and huge clearances. Even had to fit a spacer beneath the seatstay bridge to drop the guard down a bit.

I gave up on the instructions and just used whichever bolt I thought worked. And a couple from my spares box. The ones that came with the frame had tiny, shallow hex heads, and would've been a nightmare to remove after a winter or two.

At one point I wasted about 10 minutes trying to get the wrong nuts to thread onto the bolts that secure the stays to the guards. The correct ones look virtually the same :x

On my winter Racelight Tk I have 25mm tyres and Chromoplastics. It's designed to take them but getting the rear wheel back in can still involve a bit of a fight with the rear mech and some shoving.

Thanks, that might work. I've got plenty laying around. I'll give it a try.

I don't think it's any thicker than any other one. It's about the same as on my other two bikes. And when I say it's not long enough, I mean the bolt would probably need to be at least twice as long to fit. Unless there is some method which is illuding me atm, where it works.

fenix

And there's definitely no other bolt that is twice the length of the one you're trying to use ?

keef66

Can you assemble it with that little R shaped clip which then is a push fit over the chainstay bridge?

Those bits I never use so I've now collected 3 of them. Although the tiny nuts and bolts come in handy later when the aluminium rivets invariably dissolve and you suddenly find the guards floating independently of the stays

There were three packets: one with some gubbins for fixing the stays in, one with general nuts and bolts and bits, a third with the bits in for the bridge attachment. The last one only contains one bolt. The other bolts in the other packet all have the same head

I don't have an R shaped clip? They're SKS Bluemels if that's any help?

I tried using a cable tie and they are still no good. They are rubbing underneath the seatstay bridge. They are supposed to fit, but they don't! I wish I'd never bought the bloody things.

Rubbing the tyre ?

Just take the bike into a LBS - they'll have fitted loads. It is tricky - if you do something wrong at the chainstay bridge it can make it rub elsewhere.

I haven't done anything wrong. They're just isn't enough clearance. The seatstay bridge attachment is as high as it will go and they are rubbing. And I don't have a lbs.

This feels like de ja vu with a previous thread, possibly around this time of year even.

I think you need to move to a country where mudguards are not required - that's what I would like to do too, thinking about it.

Except that these ones are supposed to fit. They don't.

bungle73

Judging from what I've read someone say in a user review, and from I observed, I think the seatstay bridge bracket is just too big. And someone else says they were tight with their 25s, and they doubted if they would fit 28s. They are supposed to fit 28s.

Send them back, get a set of clip on SKS Raceblade XL’s.

Problem solved.

bungle73

I think I've come to conclusion that they just won't fit. So someone is lying: either these are not designed to accommodate 28 tyres at all, or my bike is not actually designed to have 28s and mudguards.

All I wanted was something to shield me and the bike from winter road crap.If I'd known what I thought would be a simple process of buying some mudguards was going to be such big hassle I might not have even bothered in the first place. I'm not sure I can be bothered anymore

I did actually look at those before my purchase, but the ones I looked at were a lot more expensive, and I thought since my bike had the bosses that I'd be better of taking advantage of them and using full mudguards.

You could try smaller tyres?

Wouldn't that be putting the cart before the horse somewhat, especially since tyres are a lot more expensive, the fact the I bought the tyres I have specifically for the winter, and also the ones I have are (apparently) quite small for "28s" anyway.

bungle73

I'd also looked at the Crud Roadracers, but people's opinions on them seemed mixed, they seemed a bit flimsy, and I'm nut sure I liked the idea of sticking velcro to my bike. I did like the protection they offered for the front mech and chain though - although I'm not sure if it was really any better than any other guard.

cougie

If you bought wider tyres do you have the original narrower tyres already ? For the sake of a few minutes work you might be able to get the bike working.

Already? The original tyres are too puncture prone in the winter - which is the original reason why I bought the new ones - I was getting multiple consecutive punctures last winter. Besides that's not really solving the problem as I want to use the tyres that I've got on now, plus changing tyres is a gigantic pita on my bike.

I had a similar problem fitting mudguards to my Boardman. They were fine everywhere except under the brake / seatstay bridge. That didn’t rub all the time but definitely did once the tyre was wet.

I ended up removing the seatstay attachment and cutting a section out of the mudguard that allowed it to move up past the seatstay bridge. A couple of tie wraps locked it in position. It’s been totally reliable for over a year now.
