Heh. For me, I tend to pick up acorns quite a lot. Leaves are
another frequent visitor to the innards of my fender wells. I ride
99.999% on pavement, but the nearby Southern Walnut Creek Trail that I
like to ride on goes through a heavily treed area as it's in the flood
plain for Walnut Creek.
I try to mount my fenders so that the clearance between the rear of the
fender and the tire is the tightest clearance anywhere along the fender.
That way, anything that enters between the back of the fender and the tire
should be able to continue along the path under the fender, rather than

Yes I do..Thanks.

I'm riding cream SKS P45s with 38 Little Bens and side pulls on my Sam. The
fenders are up tight against the side pulls in the front.
I hear pebbles scraping the fenders ALL THE TIME. Cottonwood leaves are a
constant annoyance. A few times during a 30 mile ride I have to stop and
pull them out
Yes, that is exactly what I am writing and believe Jan would agree with
that.

I roll with 7mm, LoupLoup Passes 650Bx38, Rivendell P45 cream Longboards.
Probably not ideal, but I'm not about to change it.

20mm of headroom when you are specifying the clearance on a custom frame.
Most people posting on these lists are not specifying a custom frame,
Interesting discussion. Just to clarify, I really do like to see 20 mm of
"air" between the top of the tire and the fender. Here is a photo:

Anything less risks trouble when your tires pick up small rocks and drag
them through th
Yes, Ted, I would say that Jan's guidance for best practices is to try to
have 8-10mm of clearance between fender and tire, everywhere. Many do go
with much less, particularly for those who try to run the absolute widest
tire their bike will take.

Bill,
Thanks for straightening me out.
Would it be fair to say that standard practice is minimum clearance of 8 to 10
mm, though some folks go with much less than that?

Thanks for the clarification, but I still think you misunderstand what Jan

saying that a 60mm wide fender is intended to use with a 42mm tire. They

Metal fenders have a rolled lip about 4 mm wide, so that uses 8 mm of real
estate. If you have 5 mm of clearance on each side that gets you to 18mm.
So a 32 mm tire will want a 50 mm tire or more. You can cheat on that
number a bit but you run more risk of both rubbing and trapping debris.

Thanks Bill,
Just for reference, in the 650B group Jan posted:
"If you use these fenders with wider tires, you encroach on the clearance
between tire and fender. We recommend 20 mm between tire and fender for
safety. If you use a tire that is about 8 mm wider, you reduce that to 12

I think you may have misunderstood what Jan writes. The only place he goes
all the way to 20mm of clearance that I know of is when you are scoping out
whether or not you have clearance on your frame. He writes you shoudl have
