Wouldn't want to get any crud on my bike. This is just from the ride in this morning...

Your chain will love all that grit .

I love my full fenders + the "draggin the ground" mud flaps I attached myself. Wouldn't ride without them at this point.

Crud like that is why i stopped mounting my pumps on the underside

Both bottle bosses are taken. I now have a small plastic bag over the head of the pump. I learned the hard way that if you let grit in there, it destroys the rings rendering the pump useless at some critical time. What's unbelievable is that this is supposedly clean highway. This is what one of my bottles looked like the other day after just over an hour of riding. Remember, this is *with* full fenders. Friggin' grit thrown down by DOT for traction....

Any pump mount I've seen mounts under the bottle cage, so you can have the pump and bottle cage on the same bosses. Like this:



Anyway, I guess that's off topic. I've posted this picture already in a couple of other threads, but here's my cassette after a 15 km ride in snow and slush, and this is on a bike with full fenders too:

If you do not have a wide soft mud flat that almost (or does) hit the ground, fenders don't keep the drive train clean. It's all about the mud flap. The closer it gets to the ground the better, to do that one needs a soft flap that will go up over something. Most of the goop comes from the bottom of the front wheel.
I've made a lot of mud flaps for my bikes and others. A wide MTB tube cut open and then glued folded back onto itself is easy, superglue works fine.. NO need the drill holes in fenders either, just crimp a piece of stiff wire around the flap and the fender will stay, and is easy to replace. A soft flap will even go up over snow.

^ going to try this, thanks

I've had pump mounts that did that, but the current Road Morph G that I have now does not. In any case, better a pump than a water bottle or battery.

Correct.

My fenders came with flaps, but I removed them because my sense of aesthetics and my aero weenie side were offended. Also, I like to run my fenders really tight -- there is neither room for the clip that holds the rear fender up nor the flaps.

Be careful rolling the bike up over a couple of steps like the entrance to the house, it's easy to step on the mudflap and trip yourself.

You just need more bikes, my weigh weenie/aero bikes don't have fenders.

Not sure I understand how tight fenders won't hold flaps on the outside of the fender and just the thickness of a coat hanger wire crimped tightly to the inside of the fender and following the curve of the fender about 1/4" in from the outside edge. Too tight to allow the thickness of a wire in there?

banerjek

I do have 5 bikes. But I like them all to be fast. I used to use a touring rig for commuting, but what I really wanted was a racer that would take a rack and a lot of abuse. So I had this one built specifically for the purpose.

Correct. I run the clearances so tight that if the ground is damp rather than wet and I go through dirt/sand, it drags. It is less than the thickness of a wire, I can only mount 700/23, and not necessarily any brand. But that is by design.

Fizzaly

Sorry i didnt see the bag but i do now, i still to this day when i go on tours i put a condom over the top of my pump. Several times i ended up with my bike looking like yours and of course got a flat, did patch go to pump it up and....nothing. Im having the same problem not as bad as you though with all the sand on the roads, its been raining in boise for the last week i haven't even bothered lubing the chain.

Where I live, the city and county have some very special grit. It is large enough and sharp enough to cut through Schwalbe Marathons like butter. It contains pieces that are shaped like goatheads, only made out of hardened, cooked tar or basalt. It really sucks that they put material down to keep the poor drunk carcissists on the road that destroys bike tires (and is obviously great for drive trains), all for the six or seven mornings per year that have even the slightest chance of ice formation. I guess it is unreasonable to expect that motorists can slow down on the rare occasions that ice may form on the roadway.

Here are my awesome home-made fenders. I needed these before I could find anything that would be long and wide enough to fit my 29'ers.

Great tip! Thanks!

Here: https://www.roadcycler.com/2008/02/to...orph-g-review/ the guy said that he's using a "Hurricane ATB Extra Mini Pump Mount" ( https://www.performancebike.com/bikes..._1031038_-1___ ) on the side of a bottle cage. Only $1.49

2manybikes

You still need 10 more bikes.

Is that a custom made bike? Do you have a full bike photo?

Maxxxie

W00t! Thanks for that. I've got one of the Topeak Road Morph pumps and I've had to mount it on my bike's rack so that I can have two water bottle cages. I'm going to get me one of those Hurricane mounts. Thanks mate!
