Commuting - Fender Dilemmer - need fenders for MTB w/26" slicks

So, I suppose this is what happens when you use the wrong bike for a particular application. I have been using a Raleigh M50, a beast of a mountain bike, for commuting. Early on I put slicks (Bontrager Select Invert, 1.5") on it to improve efficiency in town.

Recently, I decided to get fenders to keep from getting crud all over me when biking in, or after, the rain. More so now than ever because my daily commute length is going to triple in a few months when I move.

I'm having a pickle of a time finding a fender set that is narrow, so that it'll go good with my skinnier tires, but one that is not for 700c wheels. Basically, I need a fender set that'll go good on a MTB with 26" wheels, with 1.5" tires. Any recommendations?

I wish I could remember the brand on these fenders. They've been on there since 1988, basically. I bought them when the bike had 2.215" knobbies. They may look goofy - in fact, they do look goofy - but they're extremely effective with the 1.5" tires. I can't imagine commuting with any other set-up. I just wanted to show you how they look with 1.5's.

I just put Freddy Fenders (http://www.planetbike.com/fenders.html) on my hybrid. I used the medium (Hybrid/Touring 45mm wide) size which cover my 26x1.75 tires almost perfectly from side to side. Their website says the 45mm size is for 700c x 26-35mm and the 60mm size is for 26 x 1.75-2.25" - but the big ones were just too wide for me so I bought the 45mm, (which work fine on my 26 tires). They also make a 35mm size, which to me appeared to have the same mounting hardware, just skinnier, I can't comment on their fit though.

i just ordered 26 by 1.25 " tires today and SKS 26" by 50 mm fenders.

Technically, the 1.25" or 32 mm tirers are in the high end of the 45 mm fender class but they do not make 26" by 45 mm fenders. I can't believe that 5 mm will make a difference.

Planet Bike Freddy Fenders come in 2 widths. I have the "hardcore" ones and use them with 1.5 inch wide tires. I don't think your fenders can be too wide relative to the tires. Too wide would be relative to the fork, frame, and brake calipers. Wider is better as far as fending off spray from your tires.

Edit: My post is completely based on my usage of 26 inch MTB tires.

I use the Freddy Fender hardcore fenders on my MTB with 26x1.25" slicks. Pics in my sig.

I think I've come to a decision then about which fender set I'm going to order through my LBS, the SKS, P65. They're wider than what I originally intended, but indeed, as one here has pointed out, the wider the fender the better the splash protection. The SKS P65 is intended for a 26" wheel. I originally tried the SKS model that fits 700c wheels and although it was thin and would have looked good with my thinner tire, it looked goofy on my bike since it did not comform to the shape of my 26" wheel as well as I had thought it would. In this respect the SKS P65 ought to work well. Also, I decided on the SKS model instead of the Planet Bike Freddy Fenders since the material the SKS is made out of is supposed to be more durable than the freddy fenders. The LBS guy who was showing me the aluminum CAB composite material, took the fender and twisted it like a pretzel. It snapped back to shape untouched, effectively demonstrative its flexibility and inability to break.

Thanks folks.
