>>1281365>things that don't matter:>wheel sizeWithin reason. 29" does roll nicer, but the difference is minuscule. Pic related - over a series of dense obstacles 29" wheels induce less suspension travel.
>STA (within reason)Not really true. STA is crucial for climbing, as it keeps the rear planted to the ground.
>stem length (within reason)Not really. If reach is kept the same, then bikes with shorter stems will feel nicer to ride, both directions.
There is a reason why bikes over the last 15 years became slacker, longer, universally use 50mm or shorter stems and have steep seattubes :)
