Hey, that frame is obviously custom. Homeboy didn't have a clue what
he was doing ordering it that way, but at least he ordered it that
way. I can't object to someone getting what he asks for
specifically.

What baffles me is why folks who design and build bikes for their
entire careers don't seem to understand that rather than preserving
particular chainstay lengths or front centers as best for all bikes
regardless of size, what they should really be trying to preserve is
particular geometric relationships between the rider's center of mass,
steering axis, contact patches, and so forth. Some parameters, like
fork rake, should scale according to wheel diameter-- but most
parameters should scale with rider size.

A bike as ill-proportioned as the one in the picture makes as much
sense for its tall owner as a similarly proportioned bike with 20" or
24" wheels would for a shorter rider. Which is to say, it would make
no sense at all.

Living down here in Terminus 3, I don't see many long tube frames:
Aging Pre-boomer's are fairly short, the occasional athlete usually
rides an MTB with loooooong posts.
The first one I saw was a gift from the SalArmy to a fellow who had
his Fuji stolen. Same visual effect as Ryan's photo frame, asking the
question-IS THIS THE ANSWER?
But Ryan you say the frame is ridden competively sportwise? So, either
the tall rider has excellent reflexes or the height doesn't matter.
For us the ignorant what we see is not what it delivers.
Say, did the Redline Monodog's price go up during these posts?

Yes. Well. The rider apparently does ride race locally (and at any rate,
having a custom Seven suggests a fair bit of commitment), but I suspect
the answer is that this bike doesn't have any really scary handling
issues.

The reason this frame was built may revolve around the very long crank
arms. Once you specify that and your basic measurements, I assume the
maker comes back and (in the case of Seven) builds up a fairly
conventional geometry that has the usual one-size-fits-all chainstays*.

Not that bikes on the other end don't look funny, too, or at least have
their own issues. As the rider of a smaller (52-53 cm) range of frame
sizes, I can tell you that wheel overlap is routine, and quite irksome
with fenders. It's so bad that I think the Surly philosophy of 26"
wheels for their 42-54 cm Long Haul Trucker frames is sensible, and I
keep waxing and waning on whether I should build up a rigid MTB as a
commuter: toe overlap issues actually matter a bit on the commuter bike,
because if you're like me, you do spend time doing trackstands and other
low-speed manoeuvres where your toe and your fender may meet.

*I suppose these are, in a way, an argument that chainstays would be
even shorter if there was a way to do that.

right. the short chain stay theory has the camp divided. Shorts stays
give low polar moment ON weight shift while longer stay give greater
stability FOR weight shift ???????

Despite this, he doesn't seem to understand the long chainstays for
tall frames principle. He specs all his Lurch-sized frames with

I don't know that I posted this photo before, but it seems peripherally
related:

A custom Seven frame built for a very tall rider (at least 6'6") in a
nominal 70 cm frame size, to the extent that tells you anything:

http://flickr.com/photos/rcousine/875510617/

Notable features:

Standover height is 1 m (yep, this is effectively a "Standard geometry"
frame, with a horizontal TT and about 4" of exposed seatpost). Cranks
are custom 210 mm units. The head tube is about the same length as the
fork legs. The 700C wheels look lost beneath the bike.

Sorry Chalo, the wheelbase is short,

i completely agree with ttcopley's comment that that frame is
excessively large - for all the reasons he cited. i think taking
advantage of a full length seat post is a much better strategy for
accommodating a larger rider.

Tobin (ttcopley) knows of what he speaks: he's about 6'6" himself, and
rides bikes of that size. But his are bikes of the long seatpost
variety: they look like big bikes, not circus bikes.

a 635!

The captbike articles explain almost everything:
http://www.sheldonbrown.com/tire-sizing.html
http://www.sheldonbrown.com/tires.html
as far as I can tell, ASPECT or height-width ratios define 700c from
700/29 inch so when 29 is commonly said, everyone hahahahaha knows the
tire goes on a 700 rim but is fat fat fat in ASPECT like an MTB tire.
However, taking a spare CONTI from the closet, the sidewall reads
32-622 (28 x 1=BC x 13/4)
When the ERTO number shows as 32-622, ignore the fractional sizes?
622 is the operative interface of rim and tire diameters. Best to
memorize the operative rim diameter numbers.
The LBS and MO's have to deal with a sizeable population who do not
use ERTO numbers? but say fat or skinney as qualitative words.

Continental is the one tire manufacturer I am aware of the violates
"Brown's Law Of Tire Sizing". [1] For example, they sell a "20x1-1/8"
tires, which we would expect to be an ISO 29-451, but is actually an ISO
28-406.

[1] If two tires are marked with sizes that are mathematically equal,
but one is expressed as a decimal and the other as a fraction,
these two tires will not be interchangeable.

Here in Canada 28" also means 700C. Most of the old CCM bikes I've
found use 700C, though some use 26 x 1 3/8 (ISO 590). Also, my Dutch
single-speed's tires are 700C and say 28".

I do find it funny that 700C gets called 28", when in terms of
diameter it is actually smaller (622) than 27" (630)!

Now if a fat 700C is a 29 inch, what is the old roadster 28 1 1/2 (ISO
635)?

In the former case, they're for facilitating burglaries. In the latter

Yes, but was he wearing a helmet?

While on vacation, I was gobbled at by a domestic turkey, and some very
pretty domesticated gray geese. But it was my wife who had the temerity
to eat chicken while a live canary was at the table. Bad form, I

Conti is German. Germans call 700c "28 inch". Americans lately call
fat 700c tires "29 inch".

Conti City Contact (slick) is available in 700x54 (29x2.1"):

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.

Dear Chalo,

Like you, I'm not sure how well real-world tires, inflations, loads,
and surfaces correspond to simplified theory. The common notion that
contact patch area must equal load divided by psi doesn't hold up very
well, with measured contact patches being much smaller than expected
below about 70 psi on 700x25's and much larger than expected above it.

You might be able to pedal gently next to each other, start coasting,
and see if one rider slowly pulls ahead, then swap bikes and see if
things change.

But your wife may be unable to reach the pedals on your bike.

If so, you might be able to ride each bike yourself on different days.
Find a fair stretch of level road and pedal up to 10.0 mph on a
reasonably well-calibrated speedometer (a bit tricky, given the
increased load), and start coasting at some sign post. After a few
rides, you might be able to see a difference between the two bikes.
This would have the advantage of roughly equal wind drag.

But your wife may be unwilling to let you squash her bike.

If so, you might be able to mount a 700x28 front wheel on your bike
and see if there's a difference large enough to notice with just one
tire, doing the same sort of thing.

A hill might magnify any difference. That is, from the same starting
point, a bike whose tires have less rolling resistance will be going
faster at the bottom and will therefore coast even farther than if two
riders simply matched speeds on the level. Unfortunately, a coasting
match against your wife is likely to be trickier than separate runs
with you on different bikes because of the wind-drag-versus-inertia
differences.

Another trick might be to inflate your tires more, say up from 35 to
45 psi, and see if you start to outroll your wife in casual coasting
at 10 mph. If there's no discernable difference with 28% more
pressure, then the differences are probably too small (or the other
factors too variable) to measure easily.

Cheers,

Carl Fogel

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.

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

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

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

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)

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

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:

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.

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.

38 millimeter =3D 1.496062992 inch
Fits on a rim meant for a 2.3" tire? This I gotta see to believe.
2.3 inches =3D 58.42 mm!

But WTB's 622 rim is 28mm wide at the bead or 6mm wider than a CR-18
meant for a 32c not a 58.42c

I discovered 29er frames this afternoon so the figures look kinda

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.

yes a 700-38 will mount on what rim? there's a rim mounts both 2.3"
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.

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