how many stack heights do you need? given you can adjust it by adding a spacer under your stem I don’t see it as much of an issue.
Yes get that, but it is more that they could offer more options given their manufacturing process. It is not like they have to make decisions on Geos to offer for the next season and order a big batch order a load of stuff from a Taiwanese builder like Genio etc. and be stuck with inventory they can’t shift as they got the numbers wrong.
They offer 12 sizes which already shows that they have great flexibility offer lots of sizes.
For me being 6’5″ and of long leg I am likely higher stacks, I have found each time that the bars have gone up i prefer the ride, when i was looking for a longer travel bike I did look at the Atherton range (they will do custom for the carbon models but where not keen), would have liked to stick with Bird, but again thngs too low in XL sizes, but in the end got a Raaw Madonna with a nice 670mm stack, even then I still have 50mm rise bars and some spacers (i get i am an outlier in sizes terms) but given most people have spacers and riser bars, does sort of indicate that stack heights are generally too low across the bike options out there.
Anyway the alu Atherton’s look great, and as a differentiator in a difficult market they could perhaps fully make use of their manufacturing technique to offer even greater options and without having to hold a big costly inventory.
