Trek 1.2 - SKS P35 mudguard problem

morningofmagic

Hi there,
apparently (according to internet sources such as this forum) SKS P35 mudguards are supposed to fit a Trek 1.2, but I have a major problem fitting the front mudguard. The fork is too narrow and I can't push the mudguard high enough in order to leave enough clearance for the wheel. Here are some pictures (excuse the dirt; I was meant to fit the guards tonight to go for a rainy ride tomorrow, so didn't bother cleaning )

Also, while I have sort of fitted the rear mudguard (after 3h of headaches and without yet having shortened the stays due to lack of appropriate tools) the whole rear guard seems to be rotated too far towards the back. The red reflector is pointing at the ground more or less. I am using the screw at the seatpost, but it doesn't seem to be in the right place to fit for the SKS P35... Any ideas?

Is it a newer model Trek 1.2 (2012/2013)? It seems there isn't quite the same clearance on these frames as there was on older models.

Looks like you need very narrow mudguards that are also designed to stop short at the rear (at that bolt on the seat tube). SKS 'guards are designed to fit to a chain stay bridge right behind the BB.

Perhaps unsurprisingly, these Bontragers look like your best bet. Funny that they're called "Approved" but don't say what they are approved for.

Hope that helps.

You are right about the clearance on the newer models. Normal 105 brakes fit fine on my 2013 1.5 but older models needed longer reach brakes.

I have just ordered some SKS mudguards for my bike in readiness for the coming winter season. While it's not a Trek I still think this little device is a worthwhile purchase to ease the headaches of fitting the mudguards properly.

Most current road bikes have recessed bolts that fix the front and rear calipers to the frame. This means that the retaining lugs on the mudguards will usually have to be positioned in front of the front fork and behind the rear seat stays.

While this is a workable compromise it is not ideal and this may be the reason that your rear mudguard is out of position.

With the Sheldon Fender Nuts you can replace the existing caliper bolts, leaving you with a threaded point behing the front fork and in front of the rear seat stays so that you can fix the mudguard lugs in the best position (using a 6mm bolt + washer)

That sounds reasonable, however for my front mudguard the brakes are not the problem; it's the limited space between the fork and the wheel. It looks like I will have to get some different mudguards now anyways; just want to double check with my trek dealer LBS to see what they say before i spend another 30 quid..

I ended up with a crud catcher on the front and a race blade on the back of my 2013 Trek 1.5. The front fork is a real pain to fit anything to so I gave up in the end. The rear was fine after a bit of readjustment.

Just spoke to my LBS and they also suggested race blades.. Will probably go for them. Thanks.

This is a real shame. My 2011 Trek 1.5 takes SKS Longboards/Chromoplastics no problem and makes a perfect winter bike. I run it with Shimano R450 long drop brakes and the front guard is mounted ahead of the fork for what it is worth.
