Need Advice on Fenders for My Trek ION CX

I'm finally starting to see signs of spring here in Wisconsin which means a few months of soggy roads and trails. As much as I hate the look of fenders, I hate having a roost up my back even more so I'm looking for some fenders for my Trek ION CX.

Normally I wouldn't ask for advice for such a simple product, but what has me concerned are the frames mounting holes. The holes for the rear fender don't appear like they'll line-up with most rear fenders.

The lower mounting hole is on the seat tube above the front derailleur on the seat tube. The other mounting hole is on the back of where the brake bridge, but since the bike has cantilever brakes, the hole doesn't go all the way through.





Heck, now that I looked at it, I don't know how the front fender will mount either. There's not a normal eyelet down by the front skewer. Instead, there are some small screws in the fork where I'm guessing I'd have to screw in some bolt eyelets if I had them?!?

I was thinking about getting some Planet Bike hybrid fenders, but considering the odd mounting points on my bike's frame, I'm not sure they'll work:



Perhaps I should go with these quick-mount fenders instead? I don't plan on keeping them on all season long.



Or, is there something cooler and more "CX" like?

If you're just worried about keeping the backside dry, this is a good solution. Cheap and easy. I've used one for quite a while now.

I have both the Planet Bike hybrid fenders and the Planet Bike hybrid quick-mount fenders;






I like the quick mount a little more because the front fender is easy to remove without the use of tools and without removing the front wheel. The rear fender requires the removal of the wheel, but couldn't be easier. These fenders are a little less secure than the regular model. They don't move around very much, but you might lose some alignment after a rough road or contact with a wall when parking the bike. It's easy to recenter the fender without tools if this happens.

I tend to keep the rear fender on about 70% of the time during damp months, but will remove the front anytime the roads are dry. The 45mm wide model will fit most knobby 700x35's and most slick 700x38's.

Excellent... advice from someone who's had both The rear quick-mount fender looks like it has a hole drill in the 'front', likely for mounting to the frame. Do you use that? Per my issue with where the fender mounts are on my ION, I'd have to hope the fender will mount w/o any bolts.

My current tires are 700 x 34 and only have small knobbies on them. I think that's too wide for the road model of the fenders.

The quick mount rear fender has a clip to slip over a bridge that might exist on a steel bike. You might have to drill out the clip and use a screw to attach the fender behind the bottom bracket. You will need the 45mm wide fender, what tire do you have?

The picture below should show that there is no where to attach the fender behind the bottom bracket and shows the plastic plug above the front derailleur bracket that I think is a fender mount hole (for fenders that don't exist!) The tire are Bontrager CXO Team Issue. For what I use this bike for (mostly gravel trails), I really like the tires.

Yes, you will need to drill out the two rivets that hold the steel clip to the rear fender. You should be able to attach the fender using the attachment point above the derailleur band on the back of the down-tube. You should use multiple washers to secure the fender. The fender will fit the tire in the picture well, I would expect.

You won't need a hole in the brake bridge if your willing to use zip-ties to secure the clip that attaches to the fender. The clip has slots for the ties that are included.
