I have a 29" full suspension which feels good, and a 27.5 hardtail that feels "off." I haven't been able to figure out what exactly is off about it.

Purely riding position, any advice for how I could make both of these fit close to each other?

I will worry about performance characteristics later.

Just having a hard time figuring out what I need to do with the stem, bars, and seat on these two bikes to make the 27.5" fit me better.

  1. Matching reach + stem length and stack + bar rise between the two bikes should get you in the ballpark; at least when you’re standing 

  2. Geometry geeks will get you started on the difference. Assuming they are both L’s it should look something like: https://geometrygeeks.bike/compare/nukeproof-scout-275-2022-2022-l,siskiu-t7-2023-l-29/

    They aren’t that far off especially considering a hardtail will get longer and steeper at sag when an FS won’t since it sags at front and back. The siskiu is a bit longer and lower stack with a steaper seat tube angle, maybe try a 10mm longer stem on the scout, moving the seat foward in the clamp and lowering the bars / lower rise bars.

    I’d go to town with a tape measure too. The scout does have a lower bottom bracket and i think came with shorter crankset so you may want the seat just a bit higher relative to the bottom bracket (measure from the pedal surface).
