Gentemstick Mantaray 156 2019 Review by The Good Ride

The Gentemstick Mantaray 156 is a board that isn’t on Gentemstick’s site but trust us, it really does exist. We didn’t know it was $740 at the time we reviewed it.  This is isn’t cheap but now it is for sure well within the realm of being doable. It’s a board we loved, rides just as well on groomers as it does in powder and would love to have in our quiver  It’s the kind of ride that lives outside of the traditional freeride world while still working for a wide variety of directional riders.

Ethics Statement: We don’t get paid by the manufacturer to write these reviews.  We do make money from the “Where To Buy” links, but this is our best attempt at an honest and objective review from an average riders’ perspective.

How This Review Happened:  We borrowed this for an extended demo and then returned it.
Size: 156
Days:  5+ and I want more.
Riders: James (Size 9, 5’10” 185-195lbs), Grant (Size 11 6’ 160lbs), Mason and Ty from Gravity Sports at Mt. Bachelor.
Boots: Adidas Tactical ADV, Burton SLX
Insoles: Sandsole Custom Insoles,  Footprint Insole Technology Gameghangers Low Profile
Bindings: Union Atlas, Burton Genesis, Burton Genesis X
Set Up
: 22” as to the widest inserts on the front foot and back,18 front -3 back

Approximate Weight: Felt normal and maybe a touch on the heavy side of normal but well built.

Flex/Buttering:  Very stiff for its size and it isn’t much for buttering.

Sizing: The 156 felt great for most 8-10 US boots and then as you get past 10 you are pushing it on the back foot when it comes to toe/heel drag but it might be doable with really reduced footprint boots depending on stance angles and such.

On Snow Feel: Such a stiff, stable back foot weighted, friendly beast of a turning machine. That’s the best way to describe it. It feels stable bordering on semi-locked in and those edges let you know when they are engaged and it wants more pressure for a harder turn.

Edge Hold: Very strong capable grip in hard snow.  There doesn’t seem to be any disruption going on with the sidecut but the Gentemstick Mantaray 156 holds really well as long as you have more weight on the back foot than the front.

Turn Initiation:  Very quick and springy edge to edge.  It felt quick in tight trees or tight spots and it is pretty close to being a tree cheetah.

Turning Experience: I couldn’t believe how well it turned for how little camber there is in this profile.  There was soo much energy out of the turn. I’m not saying it turns like a massive camber bow underfoot board like with Korua or something like that but I kept thinking that there was a lot more camber underfoot when turning on groomers. The sidecut’s radius is really fun for making quick fast turns and it still makes wider radius turns very well.

Carving: Same thing goes here for carving as turning.  It really lays it out hard and there is a really fun ride for those that like back foot weighted carving.  That edge just really bites in and the sidecut does such a great job of engaging you into a hard turn/carve.

Skidded Turns:  Feels like it’s not ideal for those who like to skid their turns.

Speed: Pretty fast, damp and stiff.  The base really has a good glide to it and it is very damp.  You aren’t as centered on the board as let’s say the Stingray so it doesn’t feel as bomby but it is great for how far back you are on the tail.

Uneven Terrain: Really fast edge to edge and I had a very easy time turning through bumps.  It’s not bucky but the stiffer flex doesn’t like powering over uneven snow as much but it can be done.

Powder: I’d like more set back options for more US-friendly stance width options but those who buy this often ride narrower than the US average.  If you are one of those who rides with a narrow stance you will love the 9″ back on board with a 19″ stance width all the way back. For me with a stance more on the 22″ side I still can get 7″ back on board and that is a lot of good directional float.  That combined with 22mm of taper and a massive nose that has some early rise it is a great buy.

Switch: not that good but it can be done if need be.

Jumps: There is enough tail to land big jumps and the stingray is a little better but the Gentemstick Mantaray 156 does a great job with directional air.

Jibbing: nope.

Pipe: For those that don’t ride the pipe switch at any point this is a great ride.  It can carve or slash walls very well.

So, as I said in the videos’ above before I knew the price point was going to drop to $740, this board is amazing but it’s hard to justify price wise at $1,100.  However, at $740 I would say do it if it fits your specs and you like tapered directional surfy rides.  It’s not the surfiest of Gentemsticks’ line by any means but it is such a fun ride that I think has the widest appeal for most riding styles.  Other than the limited stance options with the 5×2 inserts per binding the rest is pretty positive across the board.
