N+1 Dilemma – update

Update – see comment below, option one is now out

I’ve decided to take the plunge and go N+1, specifially getting a new winter bike. Buying a new best bike and relegating the current one (Pinarello FP Quattro Ultegra Di2) will be far too expensive so that option is out. That leaves me with 3 ways of getting the new steed, each with their own pros and cons.

1) Buy a cheapish new bike such a BTwin 700AF for about £750, stick on some mud guards and I’m away.

Pros – probably the cheapest option; quick to start riding

Con – A bit boring; I would swap the wheels straight out for a spare set I have so seems like a waste of money on that component; don’t get to build anything

2) Buy a cheap frame and build up a winter bike. Evans have a Cinelli Experience for £250, stick on a 105 set. I have old wheels, bars, stem, etc at home so that would cover most of the cost

Pros – I really fancy having a go a building a bike; the frame looks lovely; makes use of bits I have hanging around

Cons – It will take a while for me to build it; might mess it up, more expensive than opt 1

3) Buy a different frame to opt 2. Take the 10sp Di2 off my current bike and put this on the new frame, add in the other components I already have and bingo, a lovely winter bike. I’d then buy 11sp Di2 for the best bike (wheels are compatable) and get the bonus of a nice upgrade on that one too.

Pros – 11sp best bike; Di2 winter bike; get to do a build; makes the most of existing parts

Cons – The most expensive option; Di2 winter bike (yes a pro and a con, not sure how it will last); not yet found a frame to do this on.

Please tell me what to do, oh wise people of the internet.
