Hey guys, stack is a measurement often used to see how high a bikes front end sits. Taller riders or riders with long legs (like myself) and lots of seat post use it to gauge the amount of saddle to bar drop we'll have.

Is it me, or do the newer fuels have identical stack heights from sizes 17.5-19.5 at 606? So basically if one wanted to upsize to minimize saddle to bar drop it literally would do nothing except give you more seat tube length? Maybe this is because the fuel is meant to have more saddle to bar drop with its XC roots?

You can use an angled upward stem, and/or use riser bars, and if the steerer isn't cut too short, you can add some spacers under the stem. Given a BB height, stack is determined, by the length of the fork and the length of the head tube (angle does figure in a little).

Thanks. I'm aware of how to compensate or get more or less saddle to bar drop, I was more just asking if its in fact true that the stack literally stays the same between those 3 sizes. Usually, between sizes the stack gets higher as the size gets larger. This only happens on the 21.5 and up. So, hypothetically, if I wanted to upsize to get less saddle to bar drop, it wouldn't work (between the 17, 18 and 19 sizes).
