Mounting Fenders

I think this is my first post, and I only visit here once in a while, so sorry in advance if this topic has been brought up before. I bought some Planet Bike Freddie fenders for my Trek 7500 FX and attempted to install them last night. My bike has brazeons for racks both front and rear, and everything else to make it the perfect commuting/ light touring bike, except one thing. There is no chainstay bridge. That, combined with the front derailleur being in the way, makes it difficult at the very best and really pretty much impossible to mount the rear fender. The instructions recommend using a zip tie to attach it to the seat stay, but with the derailleur in the way, it will flop to one side and rub the tire. Has anyone else tried fenders on a bike set up similarly? Any words of wisdom? It is raining like crazy today and I would really like to avoid the line up my back. Thanks in advance.

I opted for the Planet Bike Clip-On Freddy Fenders for my cross bike and I love them. Maybe you can exchange them? As long as I'm running 25-28c tires I can pop them on and off in about 60 seconds each. They do not require a chainstay bridge. I do have to pay special attention to where I locate the seat tube clip because it will interfere with the front derailleur if I leave it up too high. The only problem this causes though is an inability to shift into my granny ring which I only use about twice per year. They are not, however, a legitimate substitute for full fenders. I have an old commuter for that. They exist solely to let me ride with the roadies in the rain and not get half as wet as they do.

I heard that a Zefal Gizmo water bottle holder can strap onto your down tube to give you a mounting point for the fender. Sounds like you might need to notch out the fender to give your derailleur some more room?

I rode a bike for years with zips tied to the stays. Tie 'em tight. Use a pair of pliers to really tighten them. Icouldn't believe how long they lasted. I cut them out when I retired the bike last year.

Does your bike have a kickstand? I have one of those newer aluminum style ones (as opposed to the older steel ones where the cam face is visible on the stand side and there is a spring on the back). In any case, my kickstand happens to have a post that juts up on the back face of the part that clamps the chainstays with a threaded hole in it....perfectly designed to grab the leading edge of the rear fender. So check your kickstand for an attach point and look into a new kickstand if it lacks a hole.

On edit, I see you are looking to attach to the seatstay. I have SKS fenders and mine were pretty stiff just with the chainstay/kickstand attach plus the included supports. I connected mine to the seatstay as well, but it was probably stiff enough without....

When I want zip ties really tight, my fourth hand tool works like a charm.

...just sayin'

You can put 2 zip ties one to each seat stay
OR
run a large zip tie aeound the base of the seat tube and a smaller one from the fender to the tie.
I drilled a small hole 1cm from the end of my fender for a zip tie.

Get a piece of solid copper wire, you want it really stiff, with a black coating, you can probably buy a foot or so of Romex cable for installing stoves, cut off the sheathing, and take a piece of the black conductor, leave the insulation on, cut it three times the width of the distance between the chainstays, take and bend it so that it goes around the stays you end up with it shaped in an oval around the stays, with a little hook in each end, and put the hooks together, and solder the two hooks together. This effectively makes a chainstay or seatstay bridge, that you can attach to. It will not come apart until you want it to, and you can remove it, by cutting the wire.

Actually, I have seen a small adapter that can be used specifically for this. It is basically a small clamp that kind of acts like a chainstay bridge so you can snap the fender to it. I'll do a little research and see if I can find where I've seen it before. It may have been on Sheldons website.
