This is an important article - big bike makers continue to find more ways to hose the customer who is now coughing up 5 figures for a premium bike. Except that bike comes with the wrong size INTEGRATED stem and bars, and you can't order it with a different size (or if you can it may take months). And you may not be able to order a different size at all. At the very least, you are out $100s to swap these plus much labor cost to reroute hoses, bleed brakes, etc. I'm looking at you Canyon, Specialized, Cannondale, Trek, Cervelo....
But first, you need to know in advance exactly what stem size (etc) you actually need. That is what we do during prebuy fits -thanks to the Vertex Fit Cycle (choice of EF Pro Cycling) and our software, you will know EXACTLY how the bike needs to be configured before ordering anything. Or, if you want to feel the fit of the bike before you order it, no problem - we simulate it to the millimeter on the Vertex. Any bike, any configuration.
Also be aware that some of these proprietary bar-stems disallow swapping for another more adjustable system. And most cannot accept clip-on aerobars. (Canyon's T bars for example).
There are some notable exceptions: Factor Bikes allows the bar-stem size (among other things like crank length, seatpost offset) to be speced when you order the bike, and they do have a version that accepts their aerobars.
Remember that first you need to know exactly what you really need. Changing things on many of the bikes listed above (other than Factor and and a few others) after the initial build is expensive, painful, and maybe impossible.
Want to now how the pros deal with this? Just like we do - the fitting is done beforehand and every detail is speced out before the build. They of course can get any combination of parts. This is exactly what EF Pro Cycling uses our Vertex Fit Cycle for. In October they fit 60+ riders for new (not yet released at the time) road, TT, and in some cases CX bikes on the Vertex Fit Cycle 2.0. They did this in record time with unmatched precision. Our software allowed the Vertex to simulate every possible combination of frame, bars, and settings available to them. When completed, they knew exactly how to configure every aspect of each bike for each rider, including aerobar settings down to the exact mounting holes, riser counts, and more. I haven't spoken with any of the mechanics since but I am certain they appreciated the no-guessing build sheet for each athlete's bikes.
This brings to mind our original TTBikeFit slogan: "Stop guessing, start hammering!" Otherwise, it's BUYER BEWARE.
Brands that lean into integration must offer a higher level of service so riders can get the fit they need without fuss, outrageous expense, or prolonged downtime.
