Okay
So I was trying to true my 26" MTB wheel and then I got carried away and undid the entire wheel now I'm looking at new rims...
How do I know what spoke size I need? DT Swiss calculator too complicated?
What is the strongest way to lace a 32h wheel?
Are [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=60743 ]these rims[/url] awful or awesome (build wise)?

Any thoughts & responses welcome,

Cheers,
Miké

If the DT Swiss calculator is too complicated, then DO NOT build your own wheels! 😕

What hubs you got?

No experience of those rims, but depends what you want to use them for, cos 33mm is wide, very wide in fact, and 640g each is heavy. Be fine for a DH bike running 2.5" tyres, but if it's an XC bike then they'd be way too big.

What bike you building them up to go on?

Ok its a Dirt Jump Bike, but I use it for cross country too.

So I need to learn how to use the spoke length calculator... : (
I have some stock FH-M495 Shimanos and I was gunna use these [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=12628 ]spokes[/url]

Just worked out what you'll need using Spocalc (google it) based upon 534mm ERD (googled the rim dimensions).

You need 256/257 up front

You need 257/256 out back

You will be fine buying 256mm spokes all round.

I have assumed 32 hole hubs/rims here...

If 36, you need 252/254 and 254/252

Find out (google or spokeclac.xls) or measure the ERD (Effective rim diameter) of your rims.

Measure your hubs.

Use this calc

Pay just a little bit for the book from wheel pro.

The wheel pro book is excellent.

http://lenni.info/edd/ is handy for common hubs/rims and spoke calculating.

So I was trying to true my 26" MTB wheel and then I got carried away and undid the entire wheel now I'm looking at new rims...

[i]undid the entire wheel[/i]

??? Can you expand on this? Did the rim fall to pieces?

http://sheldonbrown.com/wheelbuild.html is just about as good a guide as anything IMHO - and it's free!

You dont need to use a spoke calc, you've already got the spokes and hubs. You need a rim with the same ERD (effective rim diameter) as your old rim-or within a couple if mm. I used Sheldon Brown site as a guide to build my first wheel about 15yrs ago and have done loads since. Rim swap is easy, but if you'd kept the old rim on, taped the new one to it and moved spokes over you wouldn't have to think about lacing.

Edit; your hubs are low end and weigh a tonne. Maybe not an issue in your jump bike but I dropped a load of weight from other halfs XC bike by ditching them.
