2012 Bikes

You have more winter than us though SF, I was going to make do with one bike, and three sets of tyres- slicks, cross, and studded.

That should see me through I reckon, the temptation is to get another rear wheel to make swapping between them easier.

I was just reacting to all this 'lets have less bikes' talk.
Honest answer:
The 29er will be packed away as soon as the trails freeze.
The CX-commuter with heavily studded tyres is perfect for commuting and putting in some winter road miles. I really dont need any other bike than this.

I have massive bikelust for a fatbike. Our salted roads, and frequent freeze/thaw cycle, means ice. Commuting on a fatbike with non-studded tyres might kill me. But I will have to, to justify it. For those times when I can get out on the snow. 45NRTH have mentioned carbide studded fatties on they're facebook site though. That would be brilliant.
