shimano hub replacement option ???
i have had my bike for around 13months now and the rear freehub is starting to play up and sounds very notchy in places. i tried to strip this all down to have a look at what was going on but it seems the freehub is a sealed unit and chuck away item to replace cheap.
my problem is i don't really want to throw away each and every year but more of an upgrade to somthing much more servicable. I really like the hope hubs but being a cheap sakte i'd like to do this on the cheap side if possible.
so what options do i have for a replacement hub if i want to use the existing spokes and rim (i will upgrade the nipples to brass from alloy)
details i can find so far are :-
Shimano FH-M475 rear hub 8/9 speed
Flange diameter - 61mm
overlock nut diameter - 135mm
center to flange L - 35.35mm
center to flange R - 21.75mm
RIm - Mavic X317
i'd really like hope but looking at there spec nto sure if it will "fit" without having to buy additional spokes..
Hope Pro 2 Evo 8/9 speed
flange diameter L=56mm R=54mm
Overlock nut diameter = 135mm
Center to flange L - 31.5mm
centre to flange R - 20.5mm
anyhow would love more feedback on this and somthing which i could simply buy and fit without to much more extra cost.
You can just replace the freehub body and rebuild the cup/cone bearings. A new freehub body might be $25-30. Here's the parts diagram with the freehub part number.
If you rebuild a wheel you want to use new spokes and nipples anyway, used spokes are more likely to break at the nipples when they're stress relieved again.
ok i get the idea, i htink i'll look around for a cheap replacement for now but will keep my eyes out for a used HOPE rear wheel which then next time my shimano goes wrong again i'll throw it away and use the hope one :-).
Send it in to Shimano for warranty replacement. The XT and SLX freehub assys pretty tender if you're a strong trail rider. They're XC stuff and just not up to the riggors of hammering on them. Shimano (IME) is wonderful about warranty replacement but I get tired of sending my crap back and finally went with Hope Pro II on my bikes.
FWIW, my wife who is 115# rides the XT stuff and has never had a problem.
