After some punishment on a Specialized SX Trail the factory-built wheels were breaking spokes so it was time for a rebuild.  Jason opted for some new rims at the same time as the old ones had a few flatspots – all expected on a bike like the SX.

I replaced the bearings in the rear hub with some new SKF units, and then built both hubs onto the new FR600 rims.  This is a 600g freeride rim which is single-eyeletted and welded at the seem.

Spokes are DT Swiss double-butted Competitions in black and matching black DT Swiss brass nipples.

The most important thing when rebuilding a used hub is to lay the spokes in the groves formed in the hub flanges – this means that whatever lacing pattern was used originally has to be replicated.  By not laying the spokes in the existing groves the flanges are far more likely to break (never a good thing.)  The downside is that a lot of factory-built wheels dont have the hub logos lined up with the valve hole in the rim – this doesn’t effect performance but having the two lined up is a sign of professionalism.
