De-Lacing a Rim

But that would depend on the RIM on on M900 wheels, spokes may not be the correct length.

You are correct, Fluffy. I'm assuming though, that TP has considered that in selecting the 230 as his new rim and that he's not replacing, say, a Velocity DeepV. :shock:

Correct, I have considered it - hence why I made this post:

Anyone know if the spoke length for M563 and M900 hubs is the same??

I'm not yet sure if the spoke length is the same for both sets of hub/rims. This currently hypothetical discussion assumes it is, as if I need new spokes I may as well just get my LBS to do the lot!

TP, you might also want to switch the front and rear rims on the rebuild too. Even though we all know that the front wheel has more braking power than the back, most people still favor the rear brake when riding. You may find that sidewall wear on the existing front 230 is less than the back, and therefore you could expect the newly assembled wheels to have a longer life as a set if swapped front to back.

Just a thought.

This maybe an unnecessary point but - make sure you remove the cassette before unlacing / cutting spokes.

That's how I'd do it. Using the spokes from the existing M900 wheels in their current position, just replacing the rim.

Yup I agree. The easy way just like here

Really?

Most people? I've always used front brake more than the back <shrug>

A skilled rider would, but if these 230s were on a bike that was used on a college campus, or maybe Mr. Midlife putted around some trails on the thing for a year or two until the fad blew over and he dropped biking, then maybe not. Lets face it. Most MTB buyers are not 'skilled riders'

At any rate, I would stand by the observation that the rear brake is favored by most riders, by and large. Take a look at the brake pads on 10 bikes at your local shop in for repair...almost across the board I'd bet the rear pads are worn the most.

The 230 is quite a shallow rim and therefore needs a longer spoke than say a 217. I've seen it written that the ERDs differ by only 4mm, but another version had it 7mm different, which seems more like it to me (i.e., a 3.5mm difference in spoke lengths).

But that's just for a 217, depends what rim is currently on the XTR hubs whether the 230s will fit the XTR's current spokes.

Another irksome issue can be the nipples. I'm currently fitting a 221 to replace a worn-out Fir on an XT front wheel that has alloy nipples on it. Alloy nipples are marginal in any case IMO, but worse than marginal when used the second time. Thankfully I have a defunct wheel from which to scavenge a brass nipple for every alloy one that gets rounded. The experience has certainly convinced me, if I needed convincing, that alloy nipples are not worth the 20g/wheel saving.

Anthony , are you aware of the Gsport/odyssey nipples ?

http://www.odysseybmx.com/dailyword/200 ... x-nipples/

they are alloy but use a taper with a specific tapered spoke key , so you get the benefit of the lower weight with no chance of it rounding off

far from cheap at £20 though

Tallpaul, taping the rims side-by-side and moving the spokes over will work a treat.

Agreed. The only tricky part is making sure you don't scratch the new rim as you move the spokes over from the old one.
