Re: Toasted a wheel bearing on my Cranbrook.
Once you get that Shimano in your hands check and see if the flange is the same diameter as the stock hub flange. If so, then your current spokes are fine.
If not, then google 'spoke length calculator'.
Then start saving a bit of money for the darned spokes. It kinda looks as though they're not quite as cheap as I would've hoped.
