As Spring in UK struggles I'm starting to think about getting a winter bike - ideas?

[zoom-zoom]

Light in weight (i.e. something I can lift without doing in my back/neck etc)
Suitable mostly for roads and occasional cycle or muddy/stony farm tracks (not heavy-duty MTB sort of stuff)
Suitable gears for hills
Speedy enough to keep up with the 10-14mph average cycle club weekend rides (I'm 62, non-competitive, average fitness)

NOT a fat bike...I LOVE mine, but it is NOT a lightweight bike (I think it's pushing 35#s), it sucks in mud, it's slow up hills, and NOT speedy...10-14mph on a fat bike for a casual cyclist would be HARD effort. Also, they are not good at all on ice without $$ studded tires. Fluffy snow and sand are really where they shine.

Thanks so much for your response - It's good to hear that the tricross does what I thought it did! And thanks for the extra comment about the tyres. If you can bear to put fingers to keys again, could you tell me whether you ride the 25 gatorskins on stonyish 'green lanes' or just keep to tarmac?
I reckon you've been having far grimmer weather down your way than I have, here on the coast of Northumberland... we're due some sunnier times, but I'm not holding my breath!

I've been on all sorts with the gatorskins but the tyres the bike comes with are good for the rougher stuff but slow you down on Tarmac.
Mind you I now have a condor fratello and love that bike - but haven't taken her anywhere rough!
The tricross has a rack on it and can do anything I guess.
Wales was 6 degrees today. With frequent downpours. I can't tell the difference between any of the seasons since I moved here. They are all wet and cold.
