I have known several large GRR and Tour Easy (TE) [2] riders, and none of
them have had a problem with breaking rear axles. A couple of specialist
recumbent dealers direct their heaviest customers towards the Easy Racers
bikes, as they are one of the most suitable long-wheel base designs for
these riders.

Large riders only look right on long wheelbase recumbents. They look like
clowns on short wheelbase recumbents. Mr. Sherman needs to post a picture of
himself on some website (like the fabled Harry Brogan of ARBR) and then I
will advise him what kind of recumbent he should be on. I won't even charge
him anything for my counsel - just part of My Saintliness!

Your experience is exceptionally-rare.­ I do not recall ever seeing a broken
cassette hub axle, aside from one that someone rode so loose that it became
worn through. I will concede that the 15mm Phile axle goes beyond even that.
But I would not suggest to someone that a Phil hub is an answer to a problem
that doesn't exist (worrying about breaking a cassette hub axle).

| I can only speak from my experience with equipment I have used and
| serviced. I have messed up cassettes and gearhubs, but not freewheels
| (despite most of my miles being on freewheel-equipped bikes). The
| multispeed freewheels I've used include various Suntour, Shimano,
| Sachs-Maillard, SunRace, and Falcon models in 5, 6, and 7-speed
| versions.
|
| It stands to reason that cassette ratchets would not be as hardy as
| their freewheel equivalents-- not only is the torque applied through a
| smaller radius, but the structure holding back the expansion of the
| pawls is much less rigid. Compare the outer shell of a freehub body
| to the outer shell of any freewheel body. From what I have seen, the
| pawls themselves are more or less equivalent between the two types.

|
| To replace the ratchet mechanism of a freewheel hub, you simply
| replace the freewheel. You unscrew it with a spline tool and mount a
| new one. This operation costs at least $10 for a new freewheel.
| Usually I pay $20 for a new 11-34 7-speed freewheel. In the process,
| I get all new freewheel bearings and sprockets along with a new
| ratchet.
|
| For a cassette freehub, you have to remove the cassette lockring (a
| slightly fussier operation involving a chain whip and a different
| spline tool) and the cassette sprockets, then remove the hub axle and
| bearings, then use a 10mm hex key or a special spline tool to remove
| the freehub body. Replace the freehub body; clean, regrease, and
| adjust the axle bearings; and replace the sprockets and lockring. It
| looks like the parts cost of this operation starts at approximately
| $20 for a freehub body. The new freehub body comes with new bearings
| and pawls, but the sprockets must be replaced separately at much
| greater cost.

*Your* experience based on *your* riding style. Some of us are far pickier
about the cadence we wish to use at any particular time. I was much happier
when 9-speed cassettes came along than with the prior 8-speed systems, yet
find very little advantage (over the range I use, which is 12-27) with a 10.
But I look forward to someone coming up with a 12-29, which would give me
gearing "gaps" I can deal with and the range I would prefer. 7-speed
systems, to me, wouldn't accomplish that.

|
| I look around and see that most of the people in my town doing
| ordinary enjoyable riding are doing it on one-speed bikes-- fixies,
| cruisers, SS conversions, BMX bikes, and purpose-built SS mountain
| bikes. I guess that's sort of the same in principle as an ideal 10-
| speed "straight block" of 13-13-13-13-13-13-1­3-13-13-13 gearing, with
| nice tight 0% spacing between gears.
|
| Most of the rest of them are using derailleur bikes with no more than
| seven speeds on the cluster (because the bikes are old enough or cheap
| enough that they never had more gears than that). If you ask them how
| much they mind their "huge" jumps between gears, they won't know what
| you're talking about. The only ones with bikes whose gears have no
| "huge" jumps by your standards are the kit-wearing poseurs. And if
| you want to talk to them, you'll have to look on one of a select few
| roads around here on Sunday morning, chase after them, and stare down
| their scowls.
|
| The rest of the week, the streets belong to those who can't possibly
| enjoy riding because their gears are too far apart. Their smiles must
| be about something else.

Like I said, individuals prefer different things!

But one problem with having such a closely-spaced cassette. You can claim
that you wish you had that perfect gear when you're out there suffering on a
climb, trying to keep up, and that the lack of it is what's holding you
back. But with your cassette, that's a tough claim to prove!

I can do fine with a 12-27 (34/50) up front. Low enough gear for the hills I
ride, and not so widely spaced that I feel like it's worth changing out for
a flat century.

Hmm. Too bad Merckx didn't have a ten-speed cassette hub instead of
a lousy five-speed freewheel; it sounds he could have been a contender
for the world land speed record instead of Le Tour.

If the question is: "Would Eddy Merckx have ridden faster if he'd had better
equipment?" the answer is, with qualification, yes. If everyone else also
had the better equipment, he definitely would have ridden faster. If
everyone else didn't, then he'd possibly have ridden fast enough to beat
everyone else, but possibly not much faster than that (and thus no faster
than he would have with the equipment he used).

And he used a single one to set the world record. And he used 6 when they
first became available. And the bikes he designs are all 10. And that that
is what he rides, currently. I guess Armstrong was foolish not to retrograde
to 5, right?

Why do so many time trial bikes go with just a single front ring?

When the terrain does not require large changes in gearing, it's OK,
n'est-ce pas? So many bikes, in _specific_ time trials or prologues may be
configured that way. Will that help you understand? A big guy looking
silly looks really silly.

Yes, so my case may be unusual. I've broken axles on my upright bikes, but they
use freewheel hubs.

As I recall the axles broke at the edge of the thin end of the cone on the drive
side. I would sometimes not be aware that anything was amiss except for poor
engagement of one or two rear sprockets. After quickly checking to make sure the
cassette lock ring hadn't come loose I usually didn't investigate further until I
got home. When I unclamped the QR to remove the wheel, the works would come apart
in my hand, the wheel having been held together solely by the QR skewer.

I am a die-hard fan of corn-knob type cassettes. They allow me to
manage my cadence much more precisely, especially during the high-
speed riding.
But what does "managing" your cadence that way really get you besides
another task to stay on top of?
I could say that my coaster braked road bike allows me a free hand to
"manage" the contents of my nose. But that doesn't really expand my
riding envelope in a meaningful way.
I'd guess that if your were pressed to quantify the benefit of ten
sprockets over seven, you would not be able to demonstrate a
significant difference.
7speed cassettes force me to use triple front. 10 Speeds
allow to carry some extra sprockets to switch triple to double.
Why do so many time trial bikes go with just a single front ring?

Near constant speed on the flats. Those time trial bicycles have
nine or ten gear closely spaced cassettes.

Duuuuude!

To put it less concisely, I agree with your suspicion that you are an
unusual case.

Both you and Chalo have valid concerns about such equipment for your
needs. But that is far from saying that the design does not suit the
vast majority of its intended uses.

Being more blunt, Shimano, despite what its detractors might suggest or
suppose, has spent years and cash developing equipment that is designed
for rougher treatment and higher loads than its road groups can stand.

May I direct you to the XT/Saint/Hone lines of products? Saint and Hone
especially are burly-ized in various ways that would happen to suit
extra-heavy loads.

I respect that both you and Chalo have particular needs which are not
met by standard roadie kit, but Chalo--and now you--have demonstrated a
certain tendency to suggest that failure under his hands represents a
defect which other riders need to concern themselves with, and this is
not always true.

Both of you put stresses on equipment through your use which are out on
the long tails of the bell curve.

This is rather like me complaining that derailer drivetrains are not
sufficiently mud-resistant for normal riders, as I often experience
issues with mud contamination of my drivetrain.

(My hobby of unsupported cyclocross-type riding in a rainforest may have
something to do with that).

side. I would sometimes not be aware that anything was amiss except for poor

cassette lock ring hadn't come loose I usually didn't investigate further
until I
got home. When I unclamped the QR to remove the wheel, the works would come
apart
in my hand, the wheel having been held together solely by the QR skewer.

This is the failure mode I recently experienced with an axle on my
(5-speed freewheel hub) road bike.

#1: Non-cassette reasonably-priced hubs break axles frequently. So
frequently that they're simply impractical for most people who ride a bike a
lot. Broken rear axles are the biggest issue we have with less-expensive
bikes. They're spec'd with such hubs to save a few dollars, which generally
works if the assumption that the bike isn't going to be ridden much holds
true.

#2: The typical, reasonable-quality cassette hub+ cassette (cogs) isn't
going to cost much more than a non-cassette hub+ freewheel.

#3: Once you start talking Phil Wood, Hi-E, Mavic or White Industries,
you've left 97.358% of the world behind, in terms of affordability. I would
suggest that manufacturing product that works for the less-than-3% of the
market doesn't have as much effect on the world and making something that
creates a better $400 bike.

| How the BMX world dealt with axle breakage was by upgrading from 3/8"
| to 14mm axles, without any other basic design change. During that
| transition, you had to make an effort to spend more than $400 on a BMX
| bike, whichever axle size it had.

14mm axles were required due to the use of pegs and the effects that
"grinding" and carrying passengers have on the relevant components. It was
also a way to drop quality that much further, as a bigger axle allows for
junkier steel and still has a chance of holding up. In other words, there's
no extra cost associated with a larger axle.

| They eventually figured out what Shimano already knew-- that you could
| charge a whole lot more for a proprietary cassette hub sprocket than
| for a freewheel-- and switched over to that scheme. By producing the
| things in fast-wearing tooth counts as low as 8t, they ensure a
| bustling commerce in profitable replacement parts. Meanwhile, some
| 44/16 drivetrains that preceded the whole thing (and have been in
| regular use ever since) still soldier on, bad for business but good
| for getting the job done.

Cassette hubs allow for much-easier changing of rear cog size. As for the
"weird" stuff in the BMX market, nobody's forcing anyone to buy it. In the
early days of BMX, what sold was what was practical. Style was less
important. BMX is now more of a fashion statement than a type of bike.

No problem dumping the chain off the inside when shifting from teh 52 to the
34?

I cannot agree at all with this statement, unless perhaps bike parts
took a deep dive for the worse between 1996 and 2001 (when I was out
of the game due to a severe accident, which claimed a tooth, finally,
in 2005.)

My experience was as follows :

- 10 years riding raleigh grand prix. bent axle. not broken.
- 8 years riding sekai 2500 (early shimano 600 hubs). no problems.
- 11 years riding a trek 500 (sansin gyromaster hub). no problems.

- lots of years riding bikes with italian parts whose name cannot
be spoken (riding occasional club rides) according to mike
jacoubowsky.

- 3 months riding a bike where the derailleur hit the sprocket in
1st gear, and while riding up a 10% grade I FINALLY, in 2007,
broke an axle !!

Anyway, in my experience, 120mm and 126mm road bike axles JUST DONT
break. Your mileage may vary on mountain bikes.

*Your* experience. Not shared by any shop you're likely to ask. The axles I
broke were 120mm locknut/locknut dimesion (which is, what, 132mm overall
length?). Campagnolo. 2 of them during the days I raced. I also broke a 126
further down the road. Not mountain bikes. Road bikes. Must have been caused
by a pretty crappy out-of-alignment Cinelli that I used (which I made sure
the dropouts were perfectly aligned, because that was one of the theories
back in the day for why axles broke).

In the shop, we find and replace many such broken axles. Typically the
customer doesn't even know they're broken, because things are held in place
by the quick release. They come in because the wheel's out of true. OK, I
lied. We typically don't replace such axles in hubs anymore, because the
customer will usually say it's their 2nd or 3rd time they've "broken the
wheel." So we sell them a cassette-hub wheel and voila, no more broken rear
wheels.

Spend some time working in a shop, and you'll quickly discover that your
experiences are far better than average. Hopefully that goes for other
things in your life as well!

To be fair, I reckon a shop will tend to see worse than average, because
people bring stuff to you when it is bust. But I still reckon cassette hubs
are nicer for reasons including the axle breaking thing.

(one other important one for me is the ease of sprocket removal - anyone
who's tried to remove a freewheel used on hills on a tandem will know what I
mean here :-)­ )

It may be that RBR needs the ministrations of Ed Dolan the Great. RBR should
by rights be the most uncivil cycling newsgroup of all since it is composed
of riders who have their brains residing in their gonads. But Hells Bells, I
hate racing cyclists. My contempt for them is boundless. I doubt if could
remain civil to them for more than a few seconds.

But Fab is a jerk. If RBR hasn't figured that out, then they are even dumber
than I thought.
