picked this 2020 Cannondale up last year used-I love it color and all. I know geo is a bit outdated but fat bikes are slow to update geo not a deal breaker. 3 things I dont like #1 press fit bb-it works and no trouble I do have another press fit bike I just like threaded for service. #2 Cannondale only crank-want to put shorter cranks on-not sure what to do what crank to use. #3 Fork is a boat anchor-thinking either carbon or suspension fork unsure? 11 speed is ok-I can burn out the chain 1st before going to 12 speed. brakes work not sure of changing them? 4 piston 180/160mm rotors. figured 2/4 piston setup 180mm rotors like my hardtail setup. it can wait for now. looking to add a dropper post as well. I do have 2 tires for it 4.3 and 4.5 to test how wide to go. already had wheels trued and taped for tubeless and brakes bleed.

Can’t comment on options, but first thing to prioritize should be the dropper! Makes it more fun
I suspect any front shock will be heavier than what’s on the bike now
This will sort out your [bottom bracket situation](https://www.universalcycles.com/shopping/product_details.php?id=81120UniversalCycles–WheelsMfgPF41BB86-FATFatBikeBottomBracket-ABEC-3Bearings%5BBB86-FAT-BB,BB86-FAT-SRAM7%5D). You be able to go with different cranks and bearings.
As far as the forks go what’s your budget and where are you riding. I look at it like this, I prefer light weight so I went with carbon, I may upgrade one day to the [Lauf Carbonera fork](https://www.laufcycles.com/product/lauf-carbonaraCarbonara-LaufCycles-gravelbikes,mountainbikesandroadbikes). But that’s a lot of money. I’ll never go to a suspension fork cause I hate servicing forks, and it’s more than I need. The weight isn’t worth it.
And for brakes I’m using the SRAM G2-R, 4 piston callipers with 180mm SRAM rotors in my fat tyre set up and Hope 180mm floating rotors for my 29” gravel 2.4 tires. I got floating rotors since I ride way faster when I have the 29’s on her.
If weight is your big concern; and you haven’t switched to tubeless, consider making your wheels tubeless instead of getting rid of that porky Fork. It’s way cheaper to go tubeless than it is to get rid of a fork not to mention getting rid of rolling mass will feel lighter than getting rid of static weight. Heavy Tubes come in at 500-550 grams each, and light weight tubes are 350-375 grams each. For you to shave that much weight with a fork swap is impossible, and even if it was possible, it still would not feel as light and nimble as going tubeless. So if you haven’t gotten to consider it an option.
