cone wrench: why so massive?
 

During my usual scan of the pegboard displays at LBS, I paused to look at
blister packed cone wrenches (all were Pedro, I think). While the 13mm had more
or less reasonable dimensions and price - roughly 7" handle; about $7 - the
15mm was comparatively huge and 2x-3x the price. Sure, more steel increases
cost, but isn't 12" of leverage on a cone wrench massive overkill? I certainly
would never buy such a beast, much less carry it on the bike.

Because I didn't like the large sizes of the cone wrenches I'd seen, I made one
by grinding down the cheeks of a 13mm-15mm open-end wrench. It turned 26 years
old this month.

I'd guess the 15mm was specifically made as a pedal wrench which would
account for the larger size.

It's a pedal wrench.

Pedal wrench .... That's possible, I suppose. But it's so thin; exactly like a
cone wrench. I prefer thick jaws (more bearing surface) on wrenches that I lean
on. I like my set of Pedro tire levers but the "pedal wrench", if that's what
it is, seems ill-conceived.

I think it more than possible. I own one.

There are quite a few pedals that demand a fairly thin wrench. (It's
probably still thicker than a cone wrench, or else the cone wrenches
are unusally thick.)

Many pedals don't allow a full-width 15mm wrench to decrease the
q-factor.

It might be a dual-purpose wrench for cones and pedals.

"q-factor" Would that be "lateral bending stress"? Makes sense to me that one
would want the distance between pedal and crank to be "vanishingly small" (as my
calculus text put it).

That wasn't a cone wrench. It was a pedal wrench.
