Hi all,
I’m hoping for a bit of guidance ...
THE QUESTION
I’m looking for a used Tribike and want to know what frames have similar geometry to my previous bike which worked perfectly for me - 2009 Argon 18 E80 - 54cm TT, I’m 183cm with pretty normal proportions and ride a 56cm roadie if that helps

FURTHER INFO
- bike will be used for a training for My annual 70.3 then I’ll sell it hopefully for the same $s i buy it ($500-$1,000max) wife allows this brief period of N+1 if the bank account returns to normal shortly after my race!
- Can’t afford a bike fit at this price point as I’m looking to buy and sell without losing $s
- stupidly didn’t measure my position when I sold my last bike
- happy with Bikes up to 10 years old so just need to know what will suit me then I’ll start trawling FB marketplace (hopefully with a broader range of 3 or more bikes to look for)

YES I KNOW A BIKE FIT IS A GREAT IDEA ... but I’m Joe average and happy enjoying my 1 race a year as long as I can get comfortable on a bike, perfecting the aero /power position is secondary!

Thanks for any help
