Love my Pacenti Forzas but they are a fair bit spendier than R460s for probably not much additional benefit (e.g. they might be 15g lighter per rim, possibly 0.5mm wider, I preferred the stickers 😉 )
If I had to replace them I would possibly be looking at Kinlin XR26T (asymmetrical rear) or XR26TS (symmetrical front) which are virtually identical to the Forzas/R460s.
I thought the 511s were just a more aero version of the R460s, the weight put me off but that’s a personal choice between aero and weight I guess.
Or go all in and get some HED Begium+ Wide, shallow, light, pimp, £150/rim…
