Purple Extreme chain lube

M. Chandler said:

I've been trying out Purple Extreme chain lube, and have noticed
something odd. When I backpedal (say, to position my foot/pedal at a
stoplight), I find that there's a LOT of "friction." By friction, I
mean that the chain "sags" as if the freehub were binding. Under normal
load (i.e., pedaling) the chain behaves normally.

Anyone else experienced this?

The chain is a narrow/9-speed KMC on a LWB recumbent, and the chain was
thoroughly cleaned before applying the Purple Extreme. Most of the
riding with the PE-lubed chain has been in temps in the low- to
mid-30's, with the highest temp in the low 40's. I was using Boeshield
T-9, and never experienced the aforementioned chain "drag" before.

Dear Mark,

It's possible that your derailleur is ever so slightly
mis-aligned, which is the most common cause of chains
refusing to move backward smoothly.

Thought we figured out that you used one sample bottle on your bike and that
recumbent have about 3 times the chain of a regular road or MTB. Those
sample bottles are filled to 1/4 ounce, enough for one application on one
regular bike. You need to use 3/4 ounce of lube on a recumbent. You have
used about one third the amount of lube necessary for proper results.

There are hundreds of recumbent riders in similar conditions to yours. As
Carl suggested, it sounds like a mechanical issue as well as too little
lube.

Chain has been relubed with additional lube. The "sagging" is better,
but not eliminated.

I seriously doubt it's the rear derailleur, as this was never manifested
with "thinner" lubes (see portion of original post below).

Dear Mark,

Even the most extreme chain lube is unlikely to change its
mind according to direction.

If the chain runs smoothly in one direction, problems in the
other direction are likely to caused by the that the chain
feeds backward onto the idler pulley teeth (the chain line
can be fine), by idler pulleys faintly reluctant to spin
(unnoticed in the other direction), or by a freewheel
mechanism that's dragging slgihtly.

One way to find out if the problem is some mysterious
property of your chain lube would be to replace the chain
and see if it still binds as much when moving backward.

This experiment wouldn't really be expensive, since you'll
have to replace the chain some day.

Good luck,

Carl Fogel

I never noticed this with PE but I am new to a bent and changed the chain to a
good sram chain lubed with PE right away. it was never a problem on my DF bike.
I find it works the best if you apply it to a chain and let it dry for about a
week. when I used it on a chain and rode the same day it does not work very
well. but letting it dry I get about 400 miles out of it on my df bike.

Hi Mark
It's fall & the temp is dropping. Are you sure that U were using the
T-9 at as low of temps? T-9 has been my lube of choice for many years
now, although I open to any improvement. (It's agen ma religion to
ride in the rain)
I think this is the stuff I got a free bottle of @ Veloswap SF. Don't
know which booth put it in with a purchase. It's in my lube box, where
it will remain until I hear a lota good stuff about it. Please keep
us/me informed

Thank you for being 1 of the 1st, John

A while back, I posted about about PE lube & cold weather. Well, after
tearing apart my recumbent's drivetrain, I've found that it's the stock
lube in the Shimano LX freehub that's giving me fits. Seems it doesn't
like sub-freezing temps, and it stiffens so much that when you coast or
backpedal, the chain will sag badly.

I'm very pleased with the Purple Extreme lube, BTW. Works great, seems
quite durable, and is cleaner than Boeshield. Good stuff.

Now it's time to tear down that freehub and relube with some synthetic
motor oil...

You can spray the thing through with solvent and compressed
air and lube it without disassembling the cassette body.
That's tedious work.

I was thinking about removing the freehub body from the hub, and
flushing it w/o disassembly. Maybe use something like contact cleaner
or brake cleaner.

That's what I use, and it works great. I've found Phil Wood oil is perfect for
these too.
