Broken bike parts gallery

In another thread, Bill Bushnell posted a link to a chain failure
picture. I followed the bread crumbs and found that he has a nicely
done gallery of busted bike stuff:

I see he gets about as much life out of his tire levers as I do out of
mine. They're just completely a wear item, eh?

Dear Ryan,

Well, bicycle tire irons like the dainty one second from the left in
this picture are probably consumables for riders with tight beads on
small rims:

The black 22-inch iron is used for arguing with motorcycle tires. it's
a bit large for a seat pack, but a bicycle rim will break before that
tire iron does.

Cheers,

Carl Fogel

Especially choice-- "pinch flat through the tire":

Welcome to the wonderful world of recumbents! Now featuring delights
you didn't even know existed, like femur-breaking leg suck and pinch
flats that cut all the way through the tire casing!

I just got some of these

Let's see if they last.

N.B. I did not start the discussion on this subject.

Is this more recumbent "wisdom" from non users?

I doubt that there is enough data available for a proper statistical
analysis on the frequency of "leg suck". Since this has been brought
up as a negative, it only seems fair to point out the types of
injuries that can result to the rider's face, arms and shoulders from
a "pitch over" accident on an upright. Here are a couple of links to
stories of such experiences. [1] [2] Going over the bars on a
properly designed recumbent [3] is almost impossible; the typical
injury in a single bicycle crash is some road rash on the hip and
elbow on the rider's "down" side.

Pinch flats are a phenomenon well known to uprights, and ones that cut
through the casing appear to be an anomaly on both uprights and
recumbents. Can anyone find more recumbent examples? Note that Bill
Bushnell rides in terrain that allows for higher descending speeds
than most; if he was in the Midwest he would rarely go over 70 kph,
even with a front fairing and bodysock on his GRR.

It should be noted that Bill Bushnell is using about the narrowest and
most fragile tires available [4] (Continental GP, Schwalbe Stelvio and
Primo) in the ISO 406-mm (and larger?) sizes. The durability of these
tires should be compared to lightweight tires in ISO 19-622 and 21-622
sizes.

[3] Not the poorly designed Hypercycle [5] from the early 1980's which
seems to be responsible for many of the opinions of inherent recumbent
"defects".
[4] Except for some tires meant for the very lightly loaded front
wheels of racing wheelchairs (whose riders regularly do wheelies).

I wonder how many eyes have been lost from snapping tire levers.

Oh, I've ridden 'em, alright. I'd rank their handling qualities (the
ones I've tried) behind that of most chopper bicycles and ahead of a
front-drive, center steering upright tandem trike I once built. I was
about to take a saw to the latter when one of my more adventurous
clubmates persuaded me to let him have it.

injuries that can result to the rider's face, arms and shoulders from
a "pitch over" accident on an upright.

I've done that, certainly. It might bear pointing out that a critical
part had to break before I went on my face. It's a risk, though. Not
as big a risk as, say, *letting a foot slip off the pedals while
underway*, but it is nonetheless a risk.

Pinch flats are a phenomenon well known to uprights, and ones that cut
through the casing appear to be an anomaly on both uprights and
recumbents.

It seems nakedly obvious to me that a rider who can hop the bike,
suspend it by standing up, or at least shift weight between front and
rear wheels is radically less likely to experience such a harsh
bottoming of the tire. I'm sure this results in some risk
compensation behavior by upright riders, like (for instance) riding
over surfaces that aren't smoothly paved.

It should be noted that Bill Bushnell is using about the narrowest and
most fragile tires available [4] (Continental GP, Schwalbe Stelvio and
Primo) in the ISO 406-mm (and larger?) sizes.

That does seem like poor judgment, given that he's restricted to the
sack o' taters approach to coping with surface anomalies.

I have more difficulties getting some tyres back on - the combination
of Campagnolo wheels and Vittoria tyres being particularly diabolical
- I usually have sore thumbs for a week afterwards.
