If I remember right Matt Crampton pretty much exploded the fan on one of the early Loughborough Cateye Replicas, when doing a max sprint effort.
Think they had a bit of a redesign, and I've seen 2 or 3 of these around the stores at the velodrome.
We had a phase where we were buying the all the cateyes we could find when they appeared on Ebay, in the space of a few months 5 or 6 came on. Still the nicest feeling trainer I've used.
Screams like a banshee at full power though!
