Hey guys. Attached is a picture of my new access frame matched up yo my rumblefish. What van I expect in terms of difference in feel. Astounding can see when I match 3 of the contact points (bb, rear drop, head tube) the seat tube is about an inch farther back. The picture doesn't do a whole lot of justice but I'm wondering how different it will feel. I'm sure ill feel a bit more stretched out but what aside from that? Any info helps

rumblefish
A Head Angle 70.1°

Head Angle---------------71 deg----------71 deg--------71 deg--------71 deg
Seat Angle----------------72.5 deg-------72.5 deg-----72.5 deg-----72.5 deg

EDIT: picture deleted as it was unhelpful

Ill try to take a more even picture cause I didn't really line it up right but if you can imagine when I match everything up the seat tube is about perpendicular and about an inch back.

Line up the BB shells, and height of the rear dropouts. Then look at the differences

No insults.
Just playing Capt. Obvious to point out a similarity (failiure with my death valley dry humor)
sag will always play a big part in how the HT and ST angles change.
Shorter chainstays loft the front wheel
longer top tubes stablize at speed
Steep HTs steer quick

then i retract my previous statement, and also thank you for THIS very helpful reply... i feel that sometimes people who are very knowledgeable (yourself included) forget what it was like when you really didn't know much. i love biking, but don't know a great deal about biking geometry. i bought the rumblefish because it felt superb and really felt right on a test ride. i couldn't be happier... i then bought the access frame so that i could get a real hands on feel of what it was like to build my own setup... i don't mind if i screw up here and there because it was super cheap and i'll always have the RF to ride, so this is my learning experience, and the best way to minimize said "screw ups" and maximize progress is to ask questions of those more knowledgeable than myself... hence, you guys :)

The Access frame is not "Walmart".
Unsagged the rear axle of the fully will partly compensate for fork sag on the hardtail when lined up for a rough comparison.
IME a longer wheel base increases high speed stability no matter if it is in the chainstays or the front center, though i prefer it to be in the stays.
HTA is more about weight distribution if fork offset maintains the trail distance.

Most #s are very close. RF will be more stable at speed, with the slacker head angle and longer wheelbase (and rear suspension). The Access will likely handle better in twisty, quick turning scenarios.
this is pretty much the answer i was looking for. thanks

Sorry to disappoint. Rumblefish is Taiwanese.
The sticker on the frame means just about nothing.
Yet I've personally peeled China stickers off of several Fisher suspension bikes (while working a dealership) which are still claimed to be US made.
Pacific plant or Merida plant, they both turn out good and bad,
And both are in Asia.
The path of a bike from raw materials to trail is always fuzzy and seemingly shrouded in mystery..
I'd love (no really I would!) to see the actual places bikes come from, most people don't know that cannondale is part of Schwinn..

What the sticker means is detailed in United States Code Title 19, Chapter 4, Subtitle II, Part I, §1304 "Marking of Imported Articles and Containers"

While it might not coincide with what you think it should mean, it certainly doesn't mean "nothing."

Which "made in the US" Fishers have you pulled "made in China" stickers off of?

that's because it's not. both are owned by the same company (Dorel).
