No fair, you're not supposed to approach coherency. Whose posts will I turn into bad poetry and
soon-to-be-obscure classic rock band references?

Also great for lubricating Trac Racks (these are sliding ladder racks for pickup trucks).

I also have found the Crank Brothers telescopic lever to be a good solution.

I managed to get a 26 x 1 3/8" EA-3 tire on an S-6 rim. I couldn't remove it- it had to be cut off.
Such was my first lesson in the vagaries of bicycle tire sizing.

i would imagine you cant foresee a lever's performance based on material alone. i think the design
of the lever would have a lot to do with whether it is likely to dent a weak rim.

for instance, some plastic levers are very beefy, which i assume is to account for the inferior
strength vs. metal. (inferior as an objective, not a derrogatory word, here). becuase some are so
tall, in the dimension that gets pressed between rim and bead, i imagine they effectively make the
lever-off process even more difficult becuase the bead needs to not only get over the rim flange,
but over the larger effective diameter of [rim + tire lever] as well.

an example of this woudl be the fact that i can not use my favorite basic park tl-1 levers to
dismount really tight tires. i can slip them in under the bead, but they are too big to lever the
bead over the rim flange without a heck of a lot of force. i venture to guess that if i muscled the
bead over despite the difficulties, i woudl be riskign denting the rim.

however, my metal levers are very very thin becuase they dont have the snap-off-in-your-hand
properties of the thin plastic levers. or more concisely: because they can be. i use metal levers on
tight tires becuase they are not tall in the rim-lever-bead dimension (does that make sense?
probably not) and therefore take much less effort to lever the bead over. that lesser effort
translates to lesser force on the rim flange, and i think a lesser chance of denting said rim.

plastic levers will break, but not necessarily before denting a rim under less than ideal
circumstances. IMHO the metal levers are not outdated at all, if you are running a tire you need to
wrestle off and on.

Good point. The thin plastic lever I used snapped (not the first time I've busted one), and the
beefy one dented the rim. Maybe metal is better. I'll see how the new stuff I've ordered works
though before I experiment further.
