Hey Carbonazza, you found an even better deal then me on Eagle! I got mine from Starbike.com, they offer free shipping.
Honestly I'm really surprised by those prices. It's a lot cheaper then what I thought it would be. I'm glad I did not pick 1x11, the price difference is just over 200€.
It will be a big change for me switching from 2x9 to 1x12
CD, I'm convinced Stumpjumper 6fattie is an excellent choice!
EDIT: Bike24 price is actually 645€, out of Germany. Still the best price I've seen. I've picked my "upgrade" in red and plan to just change my chainring. My cranks are Shimano XT, 3x9
but it is rock solid and decently light (608g w/o chainring). I'm sure the position of the middle ring will be ideal for a Boost setup!
I don't understand prices in the different shops... Bike24 is 250€ cheaper then my French shop on Eagle but 100€ more expensive on the Ultegra group.
I'll take my time the day I want to change my fork for a Pike!
Still browsing through various shops... and found cheaper (still in Germany). 634€ + 10€ shipping.
