45N-Gravdal-on-bike

Riding a bike in the Upper Midwest winter can be a challenge of matching clothing to weather, trying to be seen in the long periods of darkness, but mostly, staying upright. This year we were hit especially hard with an early, wet storm that subsequently froze into a solid layer of ice.

Commuting through downtown Minneapolis, staying upright is a concern, but so is being seen. Although a lot of winter riding is done in the dark, very few of the studded tires on the market have a reflective stripe.

Enter the 45NRTH Gravdal.  A nice 700×38 size, 252 studs and a reflective stripe. The tires check the basic boxes of need, jump past the break to see what else they deliver…

Being that studded tires are typically heavy and slow, there is no expectation of extreme performance with these, even though 45NRTH calls these “high performance commuter tires”. At 842 grams, they are definitely not lightweights, but this is the 27tpi version with steel carbide studs. This version also has a non-folding wire bead.  45NRTH also sells a version of the Gravdal with folding bead, 120tpi casing, and carbide studs in aluminum bases. They don’t offer a claimed weight of the tires, so we are not sure how much weight they would save.

45N-Gravdal-Packaging

Aside from the material and weight difference, one primary point of differentiation is that the carbide studs in steel bases that are used on this tire have a different shape than the carbide studs in aluminum bases on the 120tpi tire. The higher-end tire’s studs use 45NRTH’s unique concave stud shape, whereas the 27tpi tire uses a domed tip. The domed tip, while not appearing “sharp” worked just fine, and actually quieted down the ride of the tire. The Gravdals are notably quieter than the Nokian tire with less studs that they replaced. While the concave studs might have more grip, these were adequate for street duty, and the quieter performance is greatly appreciated.

At $85, these are the most expensive studded commuter tire on the market, except for their even more expensive 120tpi siblings which cranks up to $115. Options from Schwalbe, Nokian, Kenda and Innova are all closer to the $50-$65 range, but like mentioned above, are mostly missing reflectivity. 45NRTH knows winter, and that experience transfers into the product, making the asking price seem reasonable since they work well.

The Gravdals have been mounted for the winter on the Rawland Sogn commuter test bike, so we will put them to the test and report back with a long term review when the snow melts.

That Rawland truly does it all.

Gravdal, Sogn… both Norwegian names. The funny thing is that bike & gear manufacturers in Norway use English names. When will the mimicry go full circle?

No need to wait for the end-of-season review: This is a great tire. My Schwalbe Marathon studded tire has been relegated to the rear of my snow bike. My only wish is that they should come with a few extra studs. One does tend to lose a few over the course of the winter.

I love winter biking. I refrain from biking on the street when I need studs. Why? Most cars don’t have them.

It seems like they are asking a lot for a 27 tpi, wire beaded tire. How can they justify such a higher price then the competition?

I was hoping to get the 120tpi version next year to replace my Nokians, but $115 per tire for commuting tires is just obscene.

Schwalbe make a 32mm winter studded tire with reflective strip. I use these because they are just narrow enough to use on my cross bike, which doubles as the winter bike.

@frank you talking about the Schwalbes? Commuting tires.. so you want to put some miles on and get to work? Still cheaper than a car. Must be obscene.

Schwalbe Marathon Winter’s have large reflective sidewalls and tons of siping. I have been very happy with mine.

I like 45NRTH stuff but these tires don’t look quite perfect. there is quite a bit of unstudded conact area considering the amount of metal studs you are hauling around, also i don’t see any flat protection….king of a miss on a commuter tire, eh?

I will stick with my reflective Marathon Winters for now.

I have about 200 miles on these tires, most all those miles have been during days that it was snowing or just recently snowed. If you’re concerned that these tires do not have enough studs, I have to disagree–between the tread design and the studs–the traction was incredible. I’d say almost too incredible if you’re not constantly on snow or ice. These tires suffer a lot when on dry ground, and I ended up removing all the center of the wheel (they’re covered in snow in this photo) for less resistance. It’s now a great blend between speed and traction and the fatter tire makes for a more comfortable commute.

Are you saying that you removed the center most set of studs? That’s what I was considering. If so, how do you like them now?

I just used these tires for my commute during yesterday’s first snowfall of the year, about 3 inches of snow was on the ground, and the street intersections in my neighborhood were glare ice from the cars compacting the snow before the plows came through.

I set my tires to 40psi and didn’t have any issues. I did have to keep my speed down a bit due to braking distances increasing with the wetness from the snow. I’m riding a cantilever braking system on my cyclocross bike.

The comments here are a few years old regarding the Gravdal studded tires. What is the opinion now, especially regarding a comparison to the Schwalbe winter studded time?
Thanks in advance.
