Yes, it looks much faster & lighter now - back to its racing roots. A great looking build.
I notice many people thread the brake cable through the Quadangle frame - doing this never occurred to me when I used mine, but it makes sense.
The problem with Z-rims was that they were marketed as 'indestructible', so as soon as people put them on a bike they would purposely try to bend them.
After a particularly serious 'bend', they never quite went back to true.
