This is kind of going off topic but its my thread so who cares.
One of the reasons I want a 'proper' winter bike is because I got some of those crud catcher things (the chainstay mounted ones) and have had nothing but bother with them.
From trying to squeeze them onto a frame that was clearly designed without mudguard clearance in mind to having those little brush things constantly rubbing on the rims, I've hated them. I dislike them so much that I'd rather buy a complete new bike to ride when the weather turns than persevere with them on my current one. So, in summary, I'd rather have used a bloody seatpost mounted guard.
In fact, if anyone wants a set, they can have mine for the cost of postage, if I can find them. Last time I saw them they were flying towards the far corner of the garage after I ripped them off in a rage.
Anyway, if the sale of your Alan falls through, let me know... I wish I'd seen that one a bit quicker!
