After last season's mishap at the Madera Stage Race I decided to play around with a set of Zipp cranks. Shaving off nearly a pound from the SRAM Rival cranks was a nice bonus, but other interesting surprises have popped up.
In the past seven months I've burned through two sets of ceramic bottom brackets. I'm not sure if I'm getting sloppy seconds from Zipp, but this hasn't been much fun. Each time the BB decides to bite the dust it makes the loudest click-click sound you could imagine. I'm sure a few guys riding near me at Cherry Pie yesterday were wondering what was happening to my bike. Trust me, as annoying as it is to you my fellow competitor, it's ten times worse for me. I get a bit OCD when it comes to having a quiet bike.
I'll let Zipp know about this failure and see if their steel bearings might be a better fit for me. Each breakdown of the ceramic bearings has had the same result. It feels like grit and sand has worked its way into the ball bearings; definitely not rotating smooth, but very rough. Thankfully I've got a spare set of BB's on the shelf that will keep me on the bike. If these break down again I might just have to find another crank alternative.
