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."

Geometry

NS Define AL 170 geometry chart

The Define 170 sports a 64º head angle and 76º effective seat tube angle. There are three sizes (small, medium and large); the size large has a 490mm reach and 1,284mm wheelbase. All sizes have a 438mm chainstay length and 44mm fork offset.

A flip-chip in the shock changes the bottom bracket height by 5mm and the head and seat tube angles by 0.5º.

Suspension

NS Define AL 170 1

Like 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.

NS Define AL 170 Pedal kickback chart

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.

The 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.

 C'mon prices are at least 1k to high

 Agreed. $5300+ (converted euro to USD) for performance level suspension, NX/GX mix drivetrain, guide brakes, and house brand wheels and cockpit? No thanks.
  • 23 0
 @WY228: Yup, my same thought. Alu frame, mediocre suspension and build kit at best and they are pricing it in the same range as some fully carbon rigs with better builds. Considering they are a semi-direct to consumer as you can buy online, their prices don't reflect that.
  • 30 0
 @WY228: Rocky Mountain, who already have overpriced bikes have their Altitude Alloy 70 with Factory 38 Grip2 and X2, XT (brakes/derailleur/shifter), SLX Cassette for the same $5250usd. So this thing is definitely overpriced.

 Do those Euro prices include vat, or whatever it's called over there? Not that that would make it a good deal, but less awful.

 @WY228: even for European standards where we have some very cheap and decent bikes it's overpriced... What were they thinking?

 fucking bananas. I saw ally frame and mid level suspension and thought it was some more awesome lower priced long travel bikes to make the fun bit of the sport vaguely more affordable. But no, they're mid range bikes with high end price tags.

 @shredddr: exactly. This looks like a bad deal now, but when everyone else increases prices by 30% it may look ok.
  • 2 0
 @jaame: Thats valid. I am curious to see in a year or two time if the industry is seeing a noticeable reduction in new bike sales due to the massively increased prices. Maybe more folks just upgrade parts on their existing bike since they can't afford new rigs anymore. I generally used to get a new bike every 2-3ish years but if my bike is still in good condition, geo isnt hugely outdated etc. I will definitely consider just putting some new drivetrain parts or suspension on instead of spending huge amounts for a likely "worse" bike.

 In Europe you have to add 23/22% VAT to the RRP. And now all these prices are comparable to the similar specced bikes from mainstream brands. 2021 price increases kicked all our asses....
  • 3 0
 @GTJosh: There are similarly specced bikes with lower "Suggested Retail Prices". If we assume these here will be discounted, we have to assume the others will be too. The difference remains and leaves NS still too expensive for what they are.

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.

 I have had NS rims on my DH bike for the last 6 or so years laced to Hope hubs and they rip. Never skipped a beat, they're awesome, no dents no wobbles no nothing.

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.

 @Sweatypants: NS rims are manufactured by Fratelli (Spank’s extrusion arm) that’s why they are awesome!

 I would say that the Banshee modular dropout system is better than having a mullet all the time, Why do all these companies make it so you have to have it one way or another? I want my cake and I will eat it too.

 And the Process X. Give me adjustable chainstays too! For bike park season I want long and stable, for winter trail riding season I want short and playful.

 @coletrane-mtb: The only problem with the Process X is how dry the colors are, (and the price)

 I'd prefer that a company design and perfect a single setup instead of have after thought options*. When a company has a single bike that has multiple wheels setups it seems like 1 or more of those options are going to be less than ideal. If the company takes the time to design new dropouts/linkage to accommodate the wheel change and it has gone through the whole design process thats great.

*I am not suggesting Banshee hasnt given thought to all their options and hasnt designed it appropriately.
  • 8 0
 @mtmc99: well, the difference between Banshee and the other companies hopping on the mixed wheel train is that Banshees entire branding is letting people run the bikes how they want. I do agree that bigger brands need to make more specifically focused bikes. Banshee is indeed a very boutique brand.

 Not even a Yari for 3300€ is really bad. The Rock Shox Gold belongs to bikes way cheaper
  • 21 1
 "plus a RockShox 35 fork (which is basically a Pike with a cheaper damper) " Worth noting you can't upgrade the damper to a charger on a 35 as the bore of the upper is different.
  • 11 0
 Indeed so it isn’t at all a Pike with a cheaper damper.
  • 2 0
 Also the top bushings in the lower legs are shorter in the 35 vs. a pike fork. And the air spring is different as well, more plasticky in construction. I guess that this spec is the best they could've gotten in a reasonable amount of time at this price, even if it's more expensive than the years of past. This pandemic really has messed up the bike industry in more ways than one.. :/

 Revolution is basically a pike, not 35. 35 is cheap crap

 Yeah, a 35 is basically an overgrown Recon, not a budget Pike.

 Effective seat tube.... bobbins. Its the unweighted BB to top of seat collar angle. Stick a post in there and its much slacker. Have long legs and its slacker again. An offset and angle would be more appropriate.
  • 4 0
 Yeah, measuring to the seatpost collar is definitely NOT the standard. I'm not real good at maths, but I bet the effective STA, measured to where a saddle would be, is closer to 73*.
  • 2 3
 @betsie - the issue is that if we go to google and type in average male height worldwide you will see that majority of first world countries where most MTBers are oscilates around 175-178cm. This puts the seat just above the top of the headtube. Just like with other numbers on geometry charts, tallest people (like Chris Porter or Leo Kokkonen) shout loudest. I am personally quite a lot into owning an M sized G1 but quite frankly... I know it’s just a fab and I won’t go any faster on it. Steep seat angles are to blame for longer reach development, with each degree of the seat tube angle above 74 the effective TT goes down exponentially leaving you with choice to either get some sweet steep angle for steep climbs or reach that starts to limit your range of movement.

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 Wink
  • 2 2
 From engineering standpoint I’d worry more about leverage put on dropper post when the actual seat tube angle gets slack. Especially considering the irreversible trend to make them have as much travel from shortest possible insert length which in turn decreases the initial bushing offset. Hopefully industry will move towards 34.9 internal insert diameter as a standard for longer posts. It’s just that this goes against weight weenies so there will be resistance to this. At least that’s the way I see it Smile
  • 2 0
 @justwaki: have a look at the geometry pic, the effective seat angle and ETT are from different reference angles which is simply just wrong.
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.
  • 1 2
 @betsie: Ok I see how this is confusing. I thought you meant the general issue. They messed it up here indeed. They even marked it with dashed lines in the right way but blue line is totally off.
  • 2 1
 @betsie @stevemokan

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.

 @bananowy: Hopefully they will revise the drawing then and update the article with the correct drawing.

 @betsie: Yeah I didn't think the error was that big of a deal but now I see some more comments about it so they should probably make sure they're doing their own products justice.

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 Big Grin Jesus, there's no making some people happy.
  • 1 0
 @bananowy: I hope it was a calibrated protractor. Haha.

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.

 Interesting to see the Big Betty front and rear. I haven't seen much feedback on the Big Betty as a front tire. My understanding was that it was primarily designed as a rear tire to pair with something like the Magic Mary. Does anyone have experience with the new Big Betty on the front?

 Stack is tall but not crazy, but it sure looks crazy tall and isn't helped with that top tube kink. Slightly surprised no one has shown, or even talked about, any analysis that could explain why the kink is needed. They have to know it's going be a divisive feature, you'd think they'd want to justify the function over form aspect of it. Unless there is no function and it's purely for looks... in which case, it's fugly.

 Not exactly. A ton of great frames you probably like have similar end of travel leverage. Iron Horse Sunday, Banshee Legend, probably a ton of other DW link frames. Also the small change at the end won't make the bike bottom out easily. So don't worry. That leverage curve will feel linear.
