NS Bikes has released a brand new bike. It's called the Define AL 170, it's mullet-only (29" front and 27.5" rear) and has 170mm of rear travel and 180mm up front. The frame is only available in aluminium. NS has also updated the Define 160, which is still their go-to enduro bike, but the Define 170 is designed for those who want a little more confidence and capability. According to NS, "The Define 170 will feel at home on the biggest lines in the bike park. It is the most aggressive bike in the Define range. Enduro, freeride, bike park ripper, call it what you like."

A flip-chip in the shock changes the bottom bracket height by 5mm and the head and seat tube angles by 0.5º.
SuspensionLike its shorter-travel stablemates, the Define 170 uses a Horst-link suspension layout. The leverage curve is progressive until very near the end, where it becomes slightly digressive. This shouldn't be an issue, though, whether used with a naturally progressive air shock, or a coil shock where the digressive section sits within the jurisdiction of the bottom-out bumper. Overall, the linkage has about 12% progression from start to finish, which is not particularly progressive.
There's around 100% anti-squat at sag in the 21-tooth sprocket, so it should pedal quite well. The anti-squat values drop off quickly through the travel, so the amount of sag will have a pronounced effect on pedaling efficiency. On the other hand, the levels of pedal-kickback are relatively low for a long-travel bike.
ModelsThe Define AL 170 is available in two build kits, both using the same alloy frame.

New Define AL 160The Define AL 160 has also been updated and now features revised geometry which, according to NS, offers improved pedaling and descending capabilities, plus coil rear suspension courtesy of the
X-Fusion H3C shock. It uses an alloy frame with 27.5" wheels front and rear, spec'd with a Shimano Deore drivetrain and non-series brakes plus a RockShox 35 fork (which is basically a Pike with a cheaper damper) helping to keep the cost down.

And I really wanted to be excited about them. I like them as a brand, I like the frames, geo, etc. but a 35 gold on a 3.3k EUR MSRP bike is shocking. That Define 160 out of the box needs a different fork, brakes and tyres. Even after selling OEMs, that will make for a pretty poor value bike.
is this the ebike factor... "it's only 1000/1500$ more?"
That being said, I agree the prices don't make sense. Putting together a Commencal Meta AM right now with a Kitsuma Air, ZEB Ultimate, XTR drivetrain, Hope V4 brakes, DT/Hope wheels, and then the rest of the other shit you'd need to build up a bike, I'm coming in around the same price of that Performance one, but literally every component is better down to the tires and headset even. Its like at least a level or 2 up on every single component for the same price... doesn't make sense. I HAVE always liked the stuff this company puts out, the colorways, quality, etc... but its puzzling.
*I am not suggesting Banshee hasnt given thought to all their options and hasnt designed it appropriately.
Having said that I see no issues with L, XL and XXL bikes getting steeper angles to compensate for seat tubes getting out of the way of rear wheels of long travel bikes. Some tall zealots kind of engineers themselves could argue that if we had 470 chainstays seat tubes could be straighter. But then... sooner or later they will get 32” wheels... and it will start all over again
If the ETT is defined to a point in imaginary space then the EST should be defined to the same space at least.
But... that is also bobbins, offset and angle are more important as the size range will be for people with shorter to longer legs.
Maybe worth doing the CAD to see what the difference in the actual angle is over the claimed angle.
Unless you climb with your saddle down then the 76 degrees shown is useless for climbing, flat... all apart from the saddle slammed.... oh wait, there is a dropper post collar in the way, so its useless for that too.
Smells of marketing to me.
That geo drawing is misleading. They didn't measure STA to the seat collar. They measured to the same point in space as the ETT and reach, as is the standard. It's just the drawing that they got wrong.
I've just checked it and measured to the seat collar it is 78 degrees. Measured to the ETT/reach point it's the claimed 76 degrees.
The mech eng from their engineering team, checker, approver, QA approver then copy clearance (dont think they will have copy clearance) who has a press released drawing wrong...
As it is, 76 deg at more or less stack height would be steep enough for me, but I'm 5'9". I can sympathise with tall people's problems.
Side note, I love how some muppet actually downvoted me for using a protractor and posting the result
We have to use a calibrated meter stick for drop testing our products. Cracks up but it is what it is. Then I drop them from up.the stairs and see what breaks first from what height, that's far more fun. As it sticking them in a vice and crushing them, that beats using a Lloyd's tester.
