The total for all of this was $2,000. You can't get that at Winspace! I had money left over to go full Di2 Wireless and purchase a fancy dual sided power meter. What a bargain!
Now, this was the first time assembling components to ready a bike build for my Local Bike Shop [LBS] to assemble and I was quite overwhelmed with where to start. The staff at Rinasclta Bicycle Components helped me for days on what I will need and answered my questions about Di2 compatibility, bottom brackets, and everything else for hours once I got a hold of them.
Finally I had my bike put together by my LBS and I am riding a super light 15lb Di2 Aero Climbing machine. It rides smooth, it's quick, and nimble too. I am now cruising at 21mph on flat sections solo effort with no wind. I'm destroying my old personal bests up hills by a minute or two [depending on how long the climb is]
I totally suggest making a purchase with this company.
Thank you Rinasclta Bicycle Components!
