Hi all,

I’m getting back into road cycling after a long break (about 7 years). I used to ride high-end bikes regularly but stopped because of an injury. Now I’m ready to ride again and this time I’m focusing on the used market to keep the budget reasonable. My background:I’ve ridden Cannondale exclusively for years — multiple CAAD, 6/13, SuperSix, and SuperSix Evo models between 2004 and 2018. I really like the brand and how they handle.I’m currently looking at two used bikes and trying to figure out which one makes more sense:

Option 1 : Cannondale CAAD13 2023 ($3,600 CAD)Size 54Aluminum frameShimano 105 Di2 12-speed50/34 crank, 11-34 cassetteCarbon fork + carbon seatpostHollowgram R45 carbon wheelsNew tires + new chain + new bar tape includedBike has a few cosmetic scratches, nothing seriousSold without pedals.

Option 2 : Argon 18 Gallium Disc 2022 ($2,600 CAD)Size Medium (54)Full carbon frameSRAM Force 22 (11-speed)50/34 crank, 10-28 cassette172.5 mm crank armsVision Trimax 30 clincher wheelsVittoria Rubino Pro 700×25 mm (new tires)REPENTE Quasar 142 mm saddleArgon TDSR seatpost.BMC Roadmachine 01 Four 2020
3800$CAD


Road bike BMC Roadmachine 01 four 2020 @3700$
Size 54
Drivetrain Shimano Ultegra Di2 11-speed (50/34 11/32)
Wheels DT SWISS 40MM
Handlebar 400mm
Tires Specialized Mondo 32mm
Maintenance:
Regularly maintained.
Brake bleed, chain, and cassette replaced less than 1000km ago.
Included with the bike:
Shimano Ultegra pedals
Di2 charger
Second derailleur hanger
Notes:
The bike has not been ridden since September and has been stored indoors.


My questions: Value for money: Which one is the better deal overall for the price?
Performance: Will the Di2 + upgraded wheels justify the higher price of the CAAD13? Or is the full carbon Gallium a better choice for ride quality and long-term value?
Real-world considerations: Anything to watch out for on these models (common issues, maintenance costs, parts availability)?

Thanks in advance.
