Any question answered...

wom is a combination of many factors, including rim depth, profile and construction. Zipps sound like a cruise missile even at low speeds, I think this is because they are nicely hollow but have no idea really. It might even be the dimples #marketingbollocks. At 30mph+ they sound phenomenal.

Really? Never noticed.

All I notice is the weird hollow carbon sound when clunking up to the 11T...

Discs on the other hand... wom wom wom... as proper timetriallists ride past me while I console myself with not actually being able to push the 11T...
