After my first question i was looking for a GIANT TCR ADVANCED SL that i found with ultegra DI2 10speed for approx 2500 euros.
But yesterday my favorite bike shops proposed a fantastic BMC GRANFONDO 01 full ultegra 6800 11 speed at the same price but brand new.
I know that these are two different kind of bikes , what should i prefer in your guys opinion ?
Thanks

BMC Gran fondo... The new 6800 I think is better than the old Di2. It is also new. The TCR is one heck of a bike (I own one) but going used carbon is a little tricky and that is a lot of money for a bike. Also, with the BMC I'd think you have better dealer support since it is new.

Thanks for your help isberrios i forgot to tell you that the granfondo bmc is brand new but its a 2013 model

I see that picture and it confirms, GF01. It's ok if it's a 13. I dont think the model has changed for 2014. Even if it is a 2013 you should get your dealer support in terms of lifetime adjustments, maybe some discounts in some gear and you can probably budge a pro fit in there as well. Go get it man. That's a sweet bike.

Di2 is soooooooo much nicer. Can't really compare 2 bikes with mechanical and electric.

The BMC for 3 reasons:

1. From you "favorite bike shop"
2. Brand new
3. Ultegra 6800

Get the one that fits better. If they both fit you well then get the one that rides better.

I've ridden the GF01 and its a very nice bike. Personally the Team machine SLR01 was a better fit for me so thats what I bought.

The giant is also a very nice bike.

The Giant is a race geo and BMC is endurance geo. Probably should decide which is better suited for you and test ride them both

I have a problem with my lower back , it's a disc protrusion so i will choose the bike with an higher head tube .
Consider that BMC it's suitable for long rides should be more comfortable than Giant TCR that is maybe more racing .
