what FULL fenders do you prefer?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I run the Berthoud 700cx40, and have been on the commuter for 2 years, with no issue.

If you're going to mess around with pulling them off every spring and putting them back on in the fall, stick with plastic. And you need to pay attention to what you're doing on the install - else-wise they'll rattle, rub on your tires and look awful (just like plastic fenders).

How much of a weight difference is there between the typical SKS fenders and the Honjo/Velo-Orange fenders?

I don't have any specific numbers, and it's not enough to worry about, but... when somebody says alloys are "heavy", I have to object.

The original cycle de salmon gaurde. Expensive, hard to find and a pain to fit though at 22mm wide they look fantastic

Made in France

i have two sets of planet bike speed-ez fenders. i used one complete set to make a full coverage fender for my back wheel and it worked great. i just reversed the smaller front fender when i strapped it to the seat stays. its solid too. no rubbing or rattling for sure.

I'm installing some Velo-Orange 45mm fenders. They're darned near weightless. Check back when I get 'em on and it rains.

I do not own one but I have followed one on a group ride. I do not know what size he has installed but it does go low, but not low or wide enough.

I have a dedicated rain bike [Tarmac] with SKS fenders, self made wide mud flap that almost hits the ground, and it works great [so I have heard since it does not help me what so ever].

Yesterday, a team member had the longer extension on his fender, better, but not good enough. Another few inches longer and it would work. If you do not believe me, you ride behind one and you will. If you are riding solo, they are fine.

My Honjos feel quite a bit lighter to me than the SKS fenders I've played with. For my money, Honjos are far superior to SKS, with a few exceptions: metal fenders are more difficult install (at least if you care about fender lines at all) and really want a bike that was designed for fenders. If you're having to use a bunch of P-clips and zip ties, plastic may be your better option. The same is true if you plan on putting them on and taking them off frequently. And finally, if you're planning on beating on them, plastics may stand up better. I haven't had alloy fenders break, but they will dent if you abuse them.

Hmm, could you define frequently? The Honjo's sound like my preferred option for my commuter this winter, but I would likely remove them sometime in the spring, and put them back on the following winter. Would that cause any issues, or just really take too long?

Well, frankly, I'd define frequently as "ever". Even after having installed a dozen or so over the last few years, it still takes me a good two hours to properly install Honjo fenders - on a bike designed for them. I don't take them off again except at gunpoint - and I have no experience (and don't want any!) installing them on a bike that wasn't designed for fenders in the first place.

Beyond that, I don't think there would be significant issues, unless you are stressing the fenders during removal or installation - and you shouldn't be.

The bottom line, for me, is that aluminum fenders look great and weigh essentially nothing. Technically, they even improve your aerodynamics slightly, if you worry about "performance issues". So I have no idea why anyone would ever take them off, unless they are traveling by air. Personally, if I was planning on removing and installing fenders every year, I'd almost certainly go with plastics.

Honestly, performance was my next question. Having never ridden with them extensively, do they make much difference other than weight (even if its barely noticeable)? If there isn't anything major, I really don't think I would take them off.

I have a SKS P35 Fender Set on my road bike. Bike is very tight, won't even run 700/25 tires, but the SKS P35s fit well. I didn't use any of the mounting hardware, 7 zip ties hold it perfectly, and I can install or remove them in less than 5 minutes.

I can tell absolutely no difference in the feel or performance of my bikes with or without fenders. I think it's a total non-issue.

They're not noticeable if you ride on your own but if you ride in a group and everyone else is sans fenders it's definitely noticeable. I suspect they eat 10-30W of power.

holy $%^&. i bought those hunks of junk and couldnt make them fit on my kona for $%^&. im probably just dumb. but seriously, they should market them for touring bikes, not road bikes. i went back to the clip on fenders.

Before I worked my way into my current state of obesity, I rode with the local cat. 3s every weekend. Never noticed any difference with or without fenders. They weigh about the same as my handlebar tape, and wind tunnel testing shows a slight (though negligible, IMO) aerodynamic advantage, so I wonder what makes you suspect such a large power loss.

I have some planet bike ones on my cross bike commuter, they are ok, but looking for other ideas, I have read mixed reviews on the PB road variety.
SKS P45 Chromoplastic with Planet Bike Cascadia mud flaps. Happy with them so far.

I'd like to see the aero testing. I've never done a test myself but the fenders make the wheel significantly wider particularly with the 2-3" wide fender extension on the bottom of the rear fender. Maybe I'll do some tests this winter.

SKS P35 Chromoplastics are hard to beat, if you have the clearances. Dedicated winter bike ftw.

I do like the idea of the front derailleur splash guard, nice touch.

Just my 2 cents from a guy that lives in the Seattle area.
Interesting. I'd check to make sure they're using the longest rear fender tail because if it's the one pictured on the bike in this thread then there will definitely be some backsplash. The longer fender tail is wider at the end and reaches much further than the one pictured; mine extends another 8 inches down the wheel.

Bicycle Quarterly, Volume 6 Number 1, The Aerodynamics of Real-World Bicycles. Chart 3 compares a bare bike vs. the same bike with full aluminum fenders: 8.21 Newtons vs. 8.20 Newtons at 22 MPH. Chart 4 compares a pedaling rider on a bicycle without fenders and with fenders: 26.06 Newtons vs. 25.59 Newtons. Chart 5 compares narrow tires vs. wide tires, both with and without fenders (including rider on hoods in all cases). 30.5 mm tire without fenders: 26.06 Newtons. With fenders: 25.80 Newtons. 24.5 mm tire without fenders: 25.78 Newtons. With fenders: 25.56 Newtons.

Of course, to keep it all in context, simply going from the hoods to an aero tuck drops more than 10 Newtons, so all of the fender vs. non-fender numbers are essentially meaningless - unless one is arguing that fenders cause significant drag. The bottom line appears to be that fenders act as fairings - even though they add width, they help smooth airflow over a very turbulent area.

<edit> Fenders with an additional mud flap at the bottom, whether molded in or added on, do make things worse. The BQ test showed a full leather front mud flap adding .18 Newtons of drag, bringing the total drag to .17 Newtons more than the same bike without any fenders. I'm frankly surprised it's so small; that big old mudflap on my rando bike makes me think I'm riding a semi. But in reality, I seriously doubt that a couple of tenths of a Newton are going to make much difference unless you're time-trialling.

Interesting data but I'm skeptical they actually reduce drag, particularly at different yaw angles. Is that article available on line?

You can check at Compass Bicycles, and see if the back issue is available. Generally BQ articles are not put on-line.
