I've been testing the new Panaracer GravelKing Tubeless OK tires. The ones I'm most interested in is the 'SK' version (side knob) since these are going to be fitted on our Vasara All Road bike and used in about 50/50 Gravel / Paved conditions.
They come in 2 sizes - 35mm and 40mm. I tried first the 40mm and it had just about 2.5mm clearance on either side of my chainstays. This is fine - but a little too tight for rough and muddy conditions. So, I'm downsizing the spec to 35mm.
Mounting - these are the easiest mounting 'gravel' tires I've tried. Just pop them on the rims, add some sealant, swirl it a bit, then pump up. No muss, no fuss, no CO2. I can even mount and pressure with a mini-pump! Kudos to Panaracer for getting the beads perfect on these tires!
I bring the pressure up to about 60-70psi to seat the bead, then let it weep down a bit. After riding a short distance, then check again. I've found that after a couple days of slight weeping, the tire is sealing very well with pressure loss less than 10% per week.
Here's the wheel ready to ride with the new 35mm. Now I have 35mm on both front and rear. I will test against my weekly gravel TT route and see if there's any tangible rewards or deficits.
As for the wheel itself - this is a Velocity Aileron in 28H configuration with PRG/Imezi floating rotors. This is the wheel's 1000km checkup and it still looks good. Less than .5mm lateral truing required and less than .25mm runout - mainly attributed to the rim joint. I'll bring it to zero and we'll check this again in a 1000km. So far, the Velocity Aileron is my favorite 'do anything' discbrake alloy rim. At less than 500gr it's light enough for the road category and tough enough for CX or Gravel. The BSD is perfect for any TLR tire and we've had zero failures as far as cracks or nipple bed distortion. Plus it comes in a retro-reflective coating which makes it ideal for touring , commuting or long rides at night.
