I have a couple of older carbon S-works bikes, a Tarmac and a Tricross with full fenders. I also have an aluminum Bianchi that's used for backup. I put lights on whatever bike I'm riding for about 6 months of the year between Oct and Mar. Other than fenders there isn't a big difference between the bikes I ride. I mounted a set of 28mm tires on the cross bike but haven't tried them yet as we haven't had any rain in the the last couple of months. I don't really need wide tires but I thought I would give them a try.
