Ok, let's have some fun and get some opinions rolling. Let's say you have decided to get a "new" tri bike (new to you, not necessarily brand new from a LBS or D2C manufacturer). It's April 2023, and your absolute max budget is 6k USD. That doesn't mean you MUST to spend that much, and less is perhaps better so you get less condemnation from your wife/husband/partner and can afford to register for a couple extra races in the years to come....you're just not a dentist and can't swing a 10k superbike. new complete bike, used complete bike (eBay, these forums, pinkbike, etc), TPC, custom build up from a new or used frameset, hybrid approach of any of these options, anything in play (except upgrading an existing bike you own, that is not an option!). you enjoy the idea of using the latest and greatest tech and want a cool new bike to enjoy life and go as fast as you reasonably can in training and racing for the next 5+ years. You know your pad XY so you can use that information in your purchase decision...
Go.
