Replacing spoke nipples on a Husaberg wheel??

Hi guys, you may be aware that the standard issue spoke nipples on the FS650E SM wheels are plain carbon steel with a paint coating.

I had my wheels overhauled recently, and they came back fully re-built, but the company had wire brushed the nipples leaving bare metal exposed (which would corrode up nicely in no time...)

I coated them with lacker a number of times, but recently I've noticed rust blemishes beginning to form in several places where I missed bits.

Anyway, I would like to swap them out with stainless or aluminium replacements to get rid of the problem. I have 2 questions please.

1. Can stainless or aluminium replacement nipples be bought to fit these existing spokes/wheels (metric threads on these wheels I believe, many sites in the US only sell imperial?)

2. If I was successfull buying replacements, would it be possible to replace just the nipples one-by-one, keeping the existing spokes in place, without fully breaking the wheels down again??

The specification stamp from the wheel rims (if this means anything to anyone??), is as follows;

Front: "BEHR Germany 17 x MT3.50H2-10280-05.04 - Husaberg E DOT D"
Back: "BEHR Germany 17 x MT4.25H2-10268-05.04 - Husaberg E DOT D"

Any help or advice very much appreciated?

Dunno about nipple supplies in the UK......... but you can replace the nipples one at a time however you will still most likely have to true the end result unless you can get each nipple exactly as tight as the one one that came off, which tends not to happen.

You might get away with it on a dirt bike, I have in the past, but I'd want it right on a sm.

Lube the threads and under the nipple head with some antisieze while you are at it.

You can true a wheel in the bike, just set up a pointer to work to and don't make big changes. Spoke tension goes left right, and to get up and down you have to consider the opposite side of the rim. Be patient and you should be able to get them to better than 0.5 mm run out.

in my 2008 fs the nipples are aluminium if that helps.
i guess they are available from the dealers net.

i hope that they put some copper grease when they assembled it though..

Hi all, thanks so far for the feed back. Looks like the folks who did the wheels will take them back & sort it. But he's getting me a price over the weekend for the spokes/nipples, either aluminium or s/s.

Does anyone know if the stock spoke on these wheels are metric or imperial? The fella on the phone seems to think they are imperial (which he says is the problem, because metric are so much cheaper)?

Also, how do you find out what "gauge" they are? (if this is what they are measured in).

Do I vernier measure in mm, then compare with a chart?

Thanks

Hi all, have found that the spoke & spoke nipple threads are definately metric on these bikes. Our mothership web site sells them (ref link below);

http://www.husaberg.com/Parts.25.6.html ... egory=2005

HOWEVER, I get conflicting views in what these are made of. One dealer believed them to be aluminium anodised black, another said carbon steel with a dark zinc plating....

Does anybody know for sure? I don't want to go back to carbon steel again after all this hassle.

Thanks

yo crispin, i cant help on the spoke side of things but if it says m4.5 then i'd say its a metric 4.5mm thread (im with you on this one). The thread can be checked with a thread gauge but will obviously need to be checked with an external thread (the spoke).
You may also be able to measure the pitch of the thread with a ruler but its gonna need ot be accurate on a thread that small. hope you get it sorted !

cheers Smithy, still scanning the web & dealers to get a definite on the material of those Berg web site spoke nipples or suppliers of aluminum nipples with metric threads.... I'll keep looking & let folks know when I find out so they don't have to search as long & as hard in future.
