had it as a mid layer this weekend and was very satisfied with it. even as a standalone vest

Travel ready Split /Resort binding

Easily modifiable to fit Alpine Prime bindings along with a Quiver Connector means I have a premium split/resort Straightline binding ready to rip on my travels

Epic glove with super comfort

Great quality product. Liners are amazing. Recommend using beeswax on leather palm to keep it waterproof. Holds up in wet weather

Apres and Work - Good Boots

Been running the MTE boots for years lift ops and maintenance, better than Sorrels now that they've got a zip side!

Quality base layer

These Burton base layer pants are the best! Super comfy and a good fit.

Nice sized day pack for short trips and staying light. Can't wait to get up in the mountains to use it.

Karakoram prime connect s binding Twelve edition

Been able to fit them to my new Jones splitboard now that it has arrived. Bindings look great, attachment was easy. Cannot wait to try them out. Just need some new skins!

perfect shell

the comfiest & cutest snow pants ever ! theyre super baggy so size down 1-2 sizes. best worn with some thermals under as they dont provide much warmth.

Awesome board, easy to turn and fun. Definitely a comfortable right!!

Fat boy from 12 Boards

I absolutely love the bike and use it nearly everyday.
I’m 67 years old but it’s a bit like going back to having dirt bikes in the mid seventies! Also 12 boards was easy to deal with. A great shop.

Adding another to my collection, best layer for 1st or 2nd layer.

Good quality

Looking forward to hitting up some side and backcountry this season on this board. Great board to add to my choice of ride...

Belts are amazing, better price than direct from Exway (Don't deal with Exway) these belts thicker and more durable than the OEM ones too! Highly recommend.

One binding to do it all

Great piece of equipment to take both a solid and split up the mountains, without needing to bring another set of bindings

As described. Thanks Twelve Board Store!

Slappy ST1 Inverted Hollow Lights Ultra Low Kingpin Skateboard Trucks | 8.25"

The gold standard for grind clearance.

Slappy Trucks is the brainchild of Mike Sinclair — two years of obsessive refinement in pursuit of the perfect truck. The ST1 Inverted Hollow Lights takes everything great about the ST1 and pushes it further. The ultra low inverted hollow kingpin sits deeply recessed with a shorter top bushing, creating even more grind clearance and an increased Slappy angle — meaning smoother lock-ins, zero kingpin drag on Smith grinds and feebles, and a noticeably quicker, snappier turn. No break-in time. No hang-ups. Guaranteed.

Why Ride The Slappy ST1 Inverted Hollow Light Ultra Low Kingpin Black?
✅ Ultra low inverted hollow kingpin and axle — the gold standard for grind clearance
✅ Shorter top bushing and increased Slappy angle — more clearance, snappier response
✅ More kingpin thread — dial trucks looser or tighter to your exact preference 
✅ Forged baseplate — strong, light and built to handle abuse
✅ Sold as a pair — no break-in time, mount and ride

Tech Specs:

  • Axle Width: 8.25"
  • Hanger Width: 143mm
  • Height: 53.9mm
  • Weight: 344g (per truck)
  • Grind Clearance: 12.5mm
  • Slappy Angle: 25°
  • Recommended Deck Width: 8.125"–8.375"
  • Construction: Hollow inverted kingpin and hollow axle, aluminium hanger and baseplate, forged baseplate
  • Sold as: Pair

About Slappy
Slappy Trucks started the way the best things in skateboarding do — someone obsessing over a problem until they solved it. During the pandemic, pro skater Mike Sinclair spent over two years working through endless versions of hangers, baseplates, bushings, kingpins and turning radius, chasing a truck with maximum grind clearance that didn't sacrifice the turn. Strong, light, classic in feel — and built from scratch. As Sinclair puts it, just trying to create something new with Slappy Trucks.
