My GD (and another rider’s on the same ride) totally seized on a wet Welsh ride. It’s saving grace is that it is an utter doddle to strip, even mid-ride.
Was this the latest version of the Turbo with the rubber gaiter that doesn’t have any holes in? It’s such a simple thing that the only way I can see it seizing is if crap gets into it and I can’t see how crap can get past the latest gaiter. Not saying it can’t, just that I can’t see it.
Not that I’m carrying a candle for the GD. As I say, it is ugly and I doubt I’d have considered it if I didn’t have a bike with a 27.2mm seat tube, but I can’t really fault the way it has coped with some pretty cold wet rides over the winter up here in Aberdeenshire.
