Rigida DP 2000 Safety line
From experience, I can certainly vouch for Rigida rims.
When recently refurbishing a 3 year old E-bike, I found the original rims were suffering badly from flaring of the braking surface. The weakness in the rims was a result of the wear indicators being machined far too deeply into the braking surface.
Both wheels were rebuilt by a local wheel builder who chose to use Rigida DP 2000 'Safety Line' rims. These rims are pre-drilled for 13 guage spokes which meant the original spokes could be re-used, with new nipples of course. The rims are drilled for Presta valves and therefore required re-drilling for Schrader.
As previously mentioned, the weakness with the original rims was due to the wear indicators machined into the braking surface. Rigida rims use a far better method to indicate when replacement is needed. This takes the form of a tunnel behind the braking surface incorporated into the extrusion as shown below.
When the braking surface eventually wears through, a small slit will start to appear, but the braking surface will not 'crack off ' because the inner surface of the tunnel is still intact and will prevent any tendency to flare. The cost of the rebuild for both wheels including rims, new nipples and Schwalbe high pressure rim tapes was £90.
The machine spends a great deal of time on rural trails and un-made tow-paths, so far they have proved to be excellent rims, and many times stronger than the originals.
