Hit a pretty bad pothole at the weekend which caused the rim of my front wheel to shatter into 4 peices. The hub is still intact and appears fine. Is it worth buying a new rim and spokes and rebuilding? The wheel is a Mavic Ksyrium Pro SL.
You would need to cost it out, as it pretty much comes down to the dollars cents.
With a wheel at that price point its worth considering a rebuild, presuming you have a good wheel builder at your LBS. If you buy a new wheel, ensure the cost includes having the new wheel tuned up by the LBS. (If you not buying through a shop, add the cost having a shop tune it when it arrives).
Unless the hub has low miles, consider a full service with new bearings, or at least put the cost of this into the rebuild of the wheel.
In terms of if its worth it, you may decide reusing the hub rather than adding it to a landfill adds to the worth of a rebuild over a new wheel.
The cost of Mavic spare parts makes it uneconimical to rebuild it to factory spec, but if the hub is ok, then the price of spokes and a generic rim is probably worth paying for, as you will gain valuable experience in wheel building, which can prove invaluable if a wheel goes out of true on a ride. You will also have to consider spoke type (straight pull or j bend), spoke length, and the number of spokes the wheel can accommodate. Spoke nipples also come in a variety of sizes and materials. Brass is worth the durability, but carries a weight penalty. If you have the old parts still, then just measure them and order them in those sizes. It's worth watching some Youtube tutorials before you get started, and don't be put off by things like spoke tension and dish if you are just getting started.
