85mm Seismic Speed Vent Downhill Longboard Wheels
"Too big" you say? "Those wheels are too large for my board!" you exclaim? To that I would reply "Your board is too small for these wheels!"
The 85mm Seismic Speed Vents may not be ideal for mini longboards or freeride setups, but they sure are awesome for drop-through downhill boards and riders who are determined to roll over pretty much anything that gets in the way.
The 'Speed Vents' within the wheels are helpful in avoiding the dust that would otherwise build up in there giving you all that gunky dirt that ends up getting all over your hands. And then your mom gets mad at you 'cause you've got the brand new sofa dirty, but you're like, "MOM, it wasn't me, it was the dog!" And she says, "No way, Junior, I watched you rub the dirt off your hands and onto the couch as if it were a napkin. You are SO grounded for a week. No skateboarding, no nothin'. Grounded."
Man, that would suck. Save yourself from being grounded for a week and get some wheels with vents. Even if the 85mm Seismic Speed Vents wont fit on your current setup, just find some other Speed Vents that will!
The very fastest wheel in the world - used by Joel King of England to set a Guinness World Record of 114.7 mph on a jet-powered luge! The 85mm Speed Vent is molded around our proprietary weight-saving Energy Conversion Core – possibly the raciest, sexiest core on the market. The 85mm diameter gives it the roll speed of a downhill wheel, while the weight-saving core adds the quickness and agility of a smaller wheel, as well as enhanced rebound. Combined with lips designed for pure grip, the 85mm Speed Vent is utterly unique among high-end wheels. Breakthrough performance for longboarding, downhill, GS, and even Hybrid slalom.
These are SO SMOOTH.By Ra on 2020-09-17 Verified Purchase
They make the most satisfying hiss against smooth pavement and they're fast as hell. Only problem is that I can't longboard for exercise anymore because I barely have to push with these. Delivery time was really quick too.

75a Speed Vents are magic or something. Maybe they have a secret hubset motor? I don't know, but one push and they just keep going. Sidewalk? sure. Asphalt? gotchu. Chunderblasting? yup we can do that. I have these on my Pantheon Trip, and I've slid them once or twice (terrifyingly grippy skin), but pushing and cruising em is where it's at.

Hell yes,fast, grippy as hell,sexy and long lasting,fun as hell and my absolute fav wheel,will buy again
I would give these 6 or 7 stars if I couldBy Jay Man on 2017-08-07
Holy Moly, these 77a 85mm Speed Vents practically roll themselves! This is the fastest, plushest set of wheels I've ever felt. Pure bliss. I can't recommend these wheels enough for any dedicated push/pump enthusiast. Like gliding around on a cloud, but with twin turbos. Get you some NOW!
Good Job Seismic!By Justin Rose on 2016-12-02 Verified Purchase
Great wheels for long distance. They're fast, they stay rolling and make the ride smooth as can be. I wouldn't go any smaller than the 78mm version but these are great wheels!
FantasticBy Evan Schwenk on 2016-06-05 Verified Purchase
If you're looking for a very smooth ride and huge wheels, these are for you. Warning though, they don't handle well in wet conditions.
Perform as expectedBy Bill Phillips on 2015-09-24 Verified Purchase
I use these for mild hills and pushing around town on bad pavement. On rough asphalt these are smoother, quieter and faster in 85mm 75a, than the brand name 70mm 82a they replaced.
Excellent push wheels, not as grippy as you would expect.By Joseph Robinson on 2015-08-29 Verified Purchase
I've put in a good amount of hours on these, and I must say they are fast. They're huge, so it takes some effort to get them going but once you do, they like to stay rolling, right over cracks, dirt, rocks or all the chunder you can throw at them. the lips tend to chunk a little and beware when they're fresh, hard grip until suddenly, no more grip. But definitely worth the money for push wheels.
