29er mountain tire rims?

rims for a WTB ExiWolf 2.3" 29er mountain tire
what manufacturer and where available?
are there available widths between 2.3" and 38c?

The Alex Adventurer should be just wide enough according to Sheldon's
recommendations. 24.5mm inside diameter.

SS eyelets, strong, and cheap.

is 29er, 650B territory?

"Twenty Nine Inch" is a 700 x 50, 700-52, 700-54 etc, ISO 622mm

Yes a 700-38 will mount on that rim.

and 38C? if so, which tire gets the advantage?
guessing at this seems like if the 38c got the advantage you could
come out ahead as the fat tire wobbles along anyways.
or does the fat tire need stability for general noodlin around
but if your camping with a load i guess you'd wanna go with a wide rim
and a frim 2.3" sidewall.

38 millimeter = 1.496062992 inch
Fits on a rim meant for a 2.3" tire? This I gotta see to believe.
2.3 inches = 58.42 mm!

Is WTB's 58.42mm tire mounted optimal on a WTB 28mm bead/rim width?
Are there wider 29er rims than 28mm?

I discovered 29er frames this afternoon so the figures look kinda
weird not running an MTB just borrowing long enough to feel like a
dwarf with broken knees and constipation.

But high prices; for example, Alex Adventurer 700C rims are commonly
available online for under $25ea, not the $35 these guys want. Maybe
they should fly the Jolly Roger.

I don't know but I run 55mm wide tires on 23mm wide rims with no troubles
except for some tire rub on my fork.

A 29er uses standard old 700C rims. I built up my 29er using a set of
old road wheels with narrow rims (19mm), but use 2.1" tires. Works
fine even @< 30 psi. Even if a wider rim for wider tires might have
advantages, it is not absolutely necessary.

29" = fat 700c, as Andy Muzi pointed out. There are lots of good
tires in between 700x38 and 700x60. The WTB Nanoraptor 29 x 2.1" is a
better all-purpose tire than the ExiWolf. I like slicks like the
Schwalbe Big Apple 700x50 and 700x60 more useful yet.

Schwalbe, Conti, Michelin all have 700x47 street/touring tires.

Any rim that's at least 22mm outside width should do an adequate job
for a 29" tire. The Alex DM18 is probably the best one for the money,
about $20 last I checked. The Sun Rhyno Lite is the widest rim that
every bike shop will know how to get, and the Kris Holm 29" mountain
unicycle rim is the widest 700c rim of any kind, useless for any tire
under 40mm wide:

does Holm supply first aid?
yeah. dawrf plus posterior nerve incoherence: like there's no go
forth, it's all sit and wonder what's next butbutbut like i'm not
screaming downhill thru the MTB magic forest.
so i searched into the 29er space and wondered what tires then rims
only to find narrower rims than seems reasonable. but there i have it
from the horse's mouths.

is the 29er here to stay or will wide 29er tires disappear out from
under me like 27" conti TT did?
WTB's website has a impermanent ambience totally opposite Conti's in
your face.

622 will be here for a long time as it's an established rim diameter.
I think it will stick for mtb's, especially large sizes where it looks
more proportional. I like 27" as well. Just remounted a 1 1/4" x 27"
Zaffiro a few minutes ago--it's an elegant and masculine size. I
regret converting my other 27" bike to 700c, as I should have just
rerimmed with 27s. Tires aren't scarce, and often nice ones that'll
look good hanging in the garage go on sale for stupid cheap. Nashbar's
got Paselas in 1 1/8" and 1 1/4" widths on sale now for a tenner (700c
too)

29ers are here to stay. Here in Austin you can't swing a dead cat
without knocking someone off a 29" MTB or a 29" single speed. Since
the only thing that makes a 29er is the fat 700c tire and the frame to
hold it, I reckon that they already have all the toehold they will
ever need. The question remains whether the phenomenon will be a
perpetual niche market, with half a dozen tires and half a dozen major
brand bikes forever, or whether it will grow to rival the predominance
of 26" off-road equipment. Something in between is my bet.

I just rambled all over town with my wife on my 29" city bike with
700x60 slicks. I love it-- I actually aim for small potholes just to
check it out. Yet I coast just as fast as my wife on her skinny tire
road bike.

Mass to frontal area advantage.

What are you trying to say about my wife's frontal area? ;^)

Downhill, sure-- I roll right away from her. But at the speeds we
usually ride together, aerodynamics are not a big part of the
equation. Below 10mph, I doubt frontal area comes into play as a
significant factor. Besides, she's on a flat bar road bike, and I'm
on a big ol' 29er with 8" high, 28" wide BMX bars-- hardly placing
myself at a pronounced aero advantage.

From what I can tell, my 700x60 Schwalbe Big Apples at 35psi have

close to the same RR as her 700x28 Conti Ultra Sports at 90psi. I'm
sure there is some difference, but based on my observation the
advantage could belong to either tire.

I was cool to them at first but I've come to believe they are an
excellent and proportional solution for big riders. The bike just 'looks
right' under a tall rider.

Dear Chalo,

I _think_ that you need to borrow your wife's bike and see if you
coast as far from the same speed on her 700x28's as you do on your
700x60's.

At the same 10 mph, you have considerably more mass and momentum than
she does, but I don't know whether rolling resistance scales up in a
linear fashion as load increases.

That is, your greater mass may outweigh (sorry) the drag of your
tires.

If so, you might you coast about as far and fast on your tires as she
does on hers, but you'd leave her far behind if you were using her
thinner, higher-pressure tires.

In other words, the real test may be how well each tire rolls under
the same load.

Cheers,

Carl Fogel

linear fashion as load increases.

It's a worthy question. I know the coefficient of rolling resistance
is generalized as a ratio of the force of drag to the load carried by
the tire, but in the real world it could be a variable ratio according
to load.

I know that simple measurements of tire drag on rollers don't take
into account the mostly unrecoverable losses due to shock and
vibration dissipated in the rider. A compliant tire can store more of
these inputs and largely return them to the bike's forward momentum.
Since the streets around where I live vary from reasonably okay to
terrible, this may be a factor.

I think you're right that some kind of a rollout test is in order.
I'll look for a shallow downhill into a flat section, where the total
distance to a stop can serve as the as the point of comparison. With
any luck, my wife will agree to serve as my accomplice in science.
