Gravelking SK Gravel Bike Tyres.
Called Gravelking SK and they are Priced around £30.00 per tyre, Prices can vary, Zyrofisher are the distribution company in the UK .
I found the following information about the company on there website, a very informative site full of information on how the company was first set up.

Made in Japan.

|One thing I also noticed was no direction arrow, so I presume the Gravelking can fit any way round.|
With my bike clamped in a bike maintenance stand,
First thing I had to do was remove the old tyres from my bike, I removed the wheel from the frame, if you have Hydraulic brakes I recommend using a brake spacer in between the brake pads once the wheel is off your bike, doing this could save you a lot of agrovation if you mistakenly pull on the brake lever!
I Can recommend the company called Total Bleed Solutions, link below for the brake spacers.
|Dust cap removed, release the air!|
Waiting for a reply on Instagram.
|Stans tyre sealant.|
|Syringe used to refill the bottle.|
|Wipe the rim with a cloth removing any build up of the Stans sealant.|
All ready to accept the new Panaracer Gravelking tyre.
I took the Gravelking tyre out of the card they come in, and I just cleaned up the edges of the the tyre and hanged it up on a hook to get the round shape back.
|On the name printed on the side of the Gravelkings there is a clear protection strip across the name, luckily enough I noticed it, so remove it before fitting as the strip could get in the way of installation.|
|Good side wall on the Panaracer Gravelking SK, real protection from any cuts and rips.|
ZSG - Zero Slip Grip, the rubber compound offers enhanced wear resistant, this will give you impact and puncture with sidewall protection.
|Place the tyre on the rim and feed it all the way round the rim, you should be able to pop on the last bit by hand, but if you find it a bit tough, simply get your tyre lever and pop it on.|
|Flip the wheel over and feed the other side onto the rim.|
|700 X 43C Tyre size.|
Notice the line around the edge of the tyre, this is the guidance line and it needs to be a continued space on the edge of the rim all the way round the rim.
|Once the tyre is on refit the valve.|
|Nip up the valve with a valve removal tool.|
|Time to inflate, was it possible to do it with a typical hand pump, I’m afraid not, I did try it for the sake of the review but got nowhere near to popping the side beads on the Gravel king SK.|
Fit the adapter to the valve making sure the valve is open.
|Plug your compressor in to the power socket of the car and attach the valve to the valve of the Gravelking and wait for the tyre to pop on the rim.|
| I found the pump was not powerful enough to pop the tyre bead on the rim, air was leaking top middle bottom!|
Next step was to visit Stow Tyres in the Stow, Harlow.
|Really helpful Stow Tyres.|
|Release the air and remove the valve.|
|Refill the Gravelking with the tyre sealant, I’m using Stans No More Tubes sealant, recommendation for filling is 3 fluid Ounces .|
|Place valve at the 6 O’clock position and gently squeeze your tyre sealant in the valve hole.|
|Make sure the valve stem is clear of liquid.|
|Valve back in place and tightened.|
|With the valve closed and any sealant wiped away, the wheel needs a little bounce around on the ground to evenly spread the sealant around the inner tyre.|
I put 50 PSI in the as a test, Panaracer say you could go to 60PSI!.
|Looks so nice on the wheel.|
Plenty of grip.
|The Panarcer Gravelking set off the wheels and bike very nicely.|
Plenty of clearance.
|Wheel refitted to the bike, stand back and admire!|
I like the look of the side wall and the tyre gives the Giant a bit more street card I think, a stand out from the crowd bike now.
|Front tyre on, the Gravelhugger mudguard can be moved up and down to allow for clearance.|
Looks very smart.
Test Ride. Test Ride. Test Ride.Test Ride.
The Adventure Ride was mapped out on the Komoot mapping system, I included more or less every kind of surface apart from mud, as the dry weather conditions make it impossible to find any mud trails. (At the time of the ride)
|Dusty Gravel trail, sharp stones etc.|
|The Panarcer Gravelking made easy work on any kind of track, they never once gave way Or even felt like they could not handle the tracks I was going on.|
|A great day for a ride out to test the Gravelking’s gravel bike tyres.|
|Nothing fazed the Gravelking’s. Over nettles, stones, rocks, across fields, in the woods, no punctures on the ride at all.|
|Corn field with lot and lots of sharp edges sticking out of the ground.|
|Stony, small and large stones, dusty surface.|
|Yes there was a path in there, not a good one, but the gravel bike made easy work of it.|
|Ride was totally in dry conditions, dust was everywhere on my new Gravelking tyres, my frame, all except the chain drive! (See my Revolubes Chain Lube review)|
|Over a wooden bridge and the ride took us across another ploughed field.|
|At the time of the ride very dusty paths.|
|On inspection of the tyres, apart from the dust and odd small stone caught in the tree, there was nothing to worry about, in the past I have ridden part of today’s trail and I’ve seen the Stans Tyre sealant sealing up small “P” holes.|
|End of the ride.|
It was mostly road from here on, a chance to see how well the Gravelking tyres rolled. on tarmac.
|Looking good all covered in dust!|
