Hi fellow bike-fanatics, I am eyeing a Bombtrack Beyond+ frame to build my new bikepacking expedition rig. However, I am getting confused about the geometry…
- Large: reach=434/stack=644 & XL: reach=459/stack=653.
- I am 1m87/6'2" with an inseam of 88cm/34,6".
- Goal: bars 3cm above saddle, uncut steel steerer.
- Bombtrack (2025) advices L: 1790-1900 and XL: 1880-1990 –> placing me (at 1870mm) in the upper echelon of Large and just below the XL.
- For the 2019 model: exactly the same stack and reach. However, bombtrack places me firmly in the XL-category…
- Will run velo orange crazy bars with 35° backsweep
Which size do you guys recommend? 434 reach on the large seem little, but Bombtrack would advice me to go for Large. I want an upright position with my bars 3cm above saddle. Large with longer stem or XL with more spacers? I don't want to be hitting my handlebar bag with my knees when out of the saddle. Help a very confused friend out, much appreciated!! :-))

It all comes down to individual proportions and mobility. Maybe some core muscles strength on longer rides.
I’m (183, inseam ~83, ape index 1.01) riding a HT with 455mm reach and 633mm stack. 6° backsweep, 15mm rise 800mm handlebars (with 45mm stem). I like slightly undersized bikes, but it feels like the reach could be 2-3mm bigger for the longest rides. (What means that in my case the best mwthod to estimate reach was the simplest: `reach [mm] = height [cm] * 2.5`) I also use inner bar ends and the saddle is more or less at the same height as the stem.
434mm reach sounds crazy short to me especially if you will make it even shorter with that backsweep.
