SL4 v's BMC

ghorswill

I'm thinking of an upgrade and currently have it narrowed down to 2 makes and 3 bikes.
Background
I currently ride a 2010 Specialised Sirrus Pro Carbon (Same frame geo as Roubaix with zerts Fact7r) that I have used all winter and have upgraded quite a lot, first off converting to a drop bar with Ultegra leavers and f & r mech.
I've joined a cycle club last year and mainly get out on Sundays for the club runs (60 - 80 miles)

Options
1. Tarmac SL4 Expert Di2
2. BMC TeamMachine SLR01 Di2 (2012 model) or stump up the extra for Dura Ace (non Di)
3. BMC GranFondo GF01 Di2

The prices range from £2500 (Teammachine) using wheels from my current bike (Roval Fusee SL's) to £3200 for the Tarmac SL4 Expert 2013 model.

The final option is new carbon handlebars, carbon stem, upgrade crank, cassette on my bike I reckon £500 should lavish it.

I've always ridden Specialized bikes
Questions.
Would I notice the difference between an Fact 7r and Fact 10r frame? on the Spesh. I accept the geometry is different.
Anyone any experience of the BMC's - they get good right-ups - Teammachine SLR02 came 2nd in Cycling Plus Bike of the Year.
Is Di2 worth it over mechanical? I'm sure this is asked in the forum so I'll have a search.

For the money you can do much better.
DA9000 > Ultegra Di2
Roval Fusee SL = nothing special
10r is obviously better grade but you probably won't notice much difference unless you put down decent power.
Neither BMC nor Spec do anything for me. I find them both a bit dull and would rather buy Canyon or Rose if I was looking for value.

I think my SLR01 is a fantastic bike. But i'd forget about Di2 and go for DA9000.

I have the exact model BMC you're considering. I love it, it's a brilliant frame. Check out my build here:

Yep that's the one...how do you find it on slightly longer rides?
Very nice by the way

It's the smoothest, most comfortable bike I've ridden. No issues on long rides.

I just bought the SLR02 and love it. I rode the SLR01, and it was great but a little out of my budget. So I opted for the SLR02 Ultegra build and plan to replace the wheels with lighter ones sometime in the future. You can't go wrong with the BMC's.
