Putting Eagle on my 2014 (baby blue) Surly Ice Cream Truck
 

I have the first Ice Cream Truck (baby blue). I think it is 2014. Back then it came with a 2 by. I would like to put a SRAM Eagle on it and maybe a Chris King bottom bracket. What kind of SRAM eagle combination do I need to get? Is there anything specific to the ICT that I need to know when ordering the SRAM Eagle Parts? Thanks for your responses.

What's the spindle length on the crank and which gearing are you planning to get?
