does this also apply to the cones etc for the rear wheel? can they be safely stripped?

Could you explain what you're trying to do? I doubt you are trying to purposefully "damage the
threads of the axle" when you say "strip". If you mean "salvage parts from a damaged unit for use
later" when you say "strip", why not? Perhaps you mean "modify by removing extraneous material" when
you say "strip" but except for the braking assembly I don't think there's any dead weight to remove
in a Nexus.

I'd have thought "strip" was a fairly standard term for taking something apart, to clean it and put
it back together again. I've certainly heard it applied to engines etc.

But then, I've been to yorkshire.

Subsequent messages in this thread suggest that his use of "stripped" translates to "repacked" in
U.S. English.

If you just want to remove the left cone, clean and lube its bearings, no harm in that.

The main innards of the Nexi are a series of modules, and they can be also degreased and relubed,
but it is fairly critical to use the proper grease. Almost all instances of problems with these hubs
that have come to my attention have occurred _after_ "preventive maintenance" had been attempted,
including greasing with non-approved grease.

The right cone is not removeable without a very special tool, and it is my understanding that it is
a highly critical adjustment. It is strongly recommended not to mess with it.

There isn't much to be done in there so unless there's an indication of salt-water penetration I
would leave it alone.

However, I have succesfully cleaned and relubricated a few Nexii which made horrible noises and
exuded brown water when turned on their sides. This is not for the faint of heart as there's a lot
of stuff in there! After cleaning, I used regular white lithium grease liberally at the bearing
areas on both ends (lubriplate 130AA) and a healthy amount of hypoid gear lube all across the gear
train which I had smeared with grease first. My thoughts were that the oil might run off the working
bits and grease alone might be pushed out of the way. I was trying to duplicate the effect of the
gooey black lubricant Shimano and Sachs use, without knowing what that is. The hubs I have serviced
that way have given good service in the year-plus since I did that ( I see them for tire repair).

I really didn't understand you at first, here we would say "overhaul", "rebuild" or "clean and
lubricate".

I've not been to Yorkshire but I used to ride with someone from there!

wk was correct in my meaning (an yes i am in yorkshire)

my enquire was because i was considering doing the cones on the bike, nothing drastic.

thanks

Sheldon, I've just bought a new bike (Van D SuperFly) w/ the Nexus 7 speed and I like it a lot but I
have some questions. I've read just about everything on your excellent site but sure would
appreciate your thoughts on a few more questions:
1. I've read enough posts and websites to gather that the Nexus 7 does have a bit of internal
friction associated with its dual planetary gears. (I got an excellent article on this subject
from the Technical Journal of the IHPVA (at URL ihpva.orgHP52.pdfOpen ↗. Covers
derailleurs and numerous internally-shifted hubs.) Have you found that there is any sort of
break-in period associated with the Nexus 7 which helps loosen it up a bit? This particular
site's study used primarily brand new equipment.
2. Just wondering if you had considered changing the lube in a Nexus 7 to see if there was any
significant difference in friction, say, a combination of Mobil 1 gear lube with just enough
Mobil 1 grease to thicken it to semi-liquidity. (I'm a big believer in the superior lubrication
of Mobil 1 and no, I don't work for Mobil!) Maybe a smidgen of graphite too. I am not inclined to
try this at home but you're obviously quite the experimenter and I thought something a bit
lighter with equal or better lube qualities would help the Nexus.
3. Is the difference in friction between an internal hub and a derailleur enough to really amount to
anything or do you think it's much ado about nothing?

Not that I've noticed. My Nexus replaced a Sturmey-Archer FM 4 speed, and my perception was that the
Nexus was more efficient.

The Nexus grease is not very thick, and feels very slippery indeed. I doubt that any different
grease could significantly improve the efficiency. Shimano has some _very_ smart people designing
their lubricants.

It is somewhat noticeable. I'd say the difference between a Nexus and a derailer system is about the
same as between a derailer system and a fixed gear.

How important this is depends on your priorities.

I'd read Nexus' manual carefully before changing lubes.

My Rohloff's manual says that some of the parts inside are made of composites that will be damaged
by lubes other than Rohloff's.

I have the same bike. It's the slickest city/hybrid/touring bike I've seen. I get *lots* of
attention riding the Super Fly. People want to know where they can buy one.

If your Super Fly has the Cyclone front disc brake, I suggest that you remove the pad angle
adjustment screw (concentric to larger caliper screws), and treat it with LocTite. My adjuster screw
popped out on an early ride, which sidelined the Super Fly until Van Dessel sent a replacement front
brake (Avid disc - nice upgrade, and sent very quickly). Van Dessel said they were planning to
switch to Deore mechanical discs soon, so maybe the problem is solved by now. They were very
helpful, BTW, and obviously care about their customers.

This article's results are fairly similar to other tests I've seen for the Nexus Inter 7 hub. Note
that in 5th gear, efficiency drops down as low as
83.6%. Before I saw these test results, I could already tell that 3rd, 4th and 5th gear are the
least efficient. Guess which gears I use the most? The inefficiencies are definitely noticeable.

Several different people have told me that there is a break-in period. How much of a difference it

The Nexus 7 hub constantly feels like I'm pedalling up a slight grade, except in the highest and
lowest gears. I've also had trouble keeping the gears from shifting accidentally (sensitive
light-action Revo twist shifters). When the gear alignment indicators are lined up on the hub, I
have trouble with unwanted over-shifting. I've played around with the adjustment, and finally have
it where shifting seems OK. So, if this happens, it's not just you.

Cheers,

Barry

Thanks, Sheldon, for your comments. Much appreciated! Looks like I'll be using the SuperFly for
commuting and errands around town where the slick shifting is most important; I'll save my old
Schwinn Varsity in case I ever decide to go for a reeeally long ride.

Thanks, Pete - that's a very good point you raised about the lube. Guess I'll stick with the Shimano
stuff. Since I don't ride in winter or on the beach etc. what's in my hub will likely be good for a
while anyhow...

Thanks for those observations. I was thinking about the Nexus for my utility bike but
you've cured me.

Dunno what the cost diff is (probably big bucks...) but my year-or-so on Rohloffs hasn't revealed
any problems with shifting and the effort level is pretty close to a der setup. I *think* I
notice increased effort in 7th gear, but am prepared to believe that it's just the noise working

Yes, my bike has the Cyclone front disk. I doubt I'll find a way to get mine upgraded to an Avid
though! It's the one thing my bike came without documementation for... do you know where there might
be any on the 'net? Thanks for the tip about the adjuster - I'll be sure to loctite mine. I have to
admit that it didn't thrill me to not find out the efficiency ratings of the Nexus Seven until after
buying the Super Fly but it's clear to me from the study I cited to Sheldon, that by avoiding 5th
gear it's possible to miss the lion's share of the low efficiency ratings for that hub. Consider
that there are derailers that run efficiency down to the low 90's. OTOH I really like the idea that
I'm not going to end up in a left turn lane in front of a bunch of cars, unable to shift out of 13th
gear or with a case of chain-suck at an inopportune moment. I have a couple of questions if you'd be
so kind: I'm new back to biking after a long time away from it and bought the SuperFly after giving
myself a 'crash course' in what was available. You said your SF draws a lot of attention; what is
there about it that does that? I guess to my untrained eyes, a bike is still a bike in most
respects. (I read some very good reviews on the SF before buying it, and was impressed by their
focused model range.) And what's your feeling about the Shimano Nexus 7 - is the extra drag
something that doesn't bug you much, or do you think it will prove to be an annoyance? I know
Sheldon said he's been using one of these for a while and seems enthusiastic about it. What's your
feeling about it? I'd sure appreciate any comments you (or anyone) would offer. Thanks!

If I can put in my .02 as well: with your Rohloff, per the study I found (see the URL in my first
message), 7th gear is about the least efficient, at least tied with 14th (about 88.5% efficient,
still not very bad). 5th, 10th, 12th and 13th are all below 90%. Overall, the Shimano 27 derailler
averages about 93%. Given that it's a fairly direct chain drive, I think the numbers for the Rohloff
are impressive. Re the Shimano Nexus 7, (using the same report) if you toss out 5th gear, it's
numbers aren't all that much lower than the Rohloff. 5th is the stinker. As far as Pete's experience
with shifting problems, I'm very early on in my ownership of my Nexus 7 equipped SuperFly but having
re-adjusted the shifter cable after the first few days, it shifts like a dream up and down, and
doesn't miss a shift.

Had I the money for a Rohloff I'd certainly prefer it, but I expect I'll be happy with the Shimano.
