Thanks for the info, everyone, and apologies for upsetting the Captain! I’d picked up the impression that Cannondales were often discounted heavily, but wasn’t sure if that was mainly for discontinued models.
I didn’t think there were any Cannondale dealers near me, but discovered that the bike department in an outdoor shop sells them. I popped in on the way home tonight, and they had a couple discounted by 15% (presumably old stock). They also had one Trail SL model with gears. I had a sit on it, but it didn’t really appeal to me, although the SS model would no doubt feel different with its rigid forks etc. However, I realised I don’t have enough experience to buy a bike without trying it out.
Happily, there’s a good mountain bike shop within traveling distance of me, and they encourage you to take bikes out for extended test rides on natural trails, so I’ll be buying a bike from them, discount or no discount… Hopefully, that news will cheer up the good Captain!
