Surly 29er+ Velocity Blunt 35 Knard to Follow

After several months of Knard, Knard and nothing but Knard on the front of my either my Lynskey Pro29 SL, fits nicely in the Black sheep fork, for everything short of the Maah Daah Hey after a rain or on my old Ferrous and Switchblade fork combo (plenty of room there).  Except for some railbed riding.

The Knard Rolls pretty good on the Velocity's Blunt 35. I am running it tubeless, but I was pretty conservative on the pressure and only ran it 17.5, just 1.5 psi lower than my 2.35 Ikon. I dropped another half PSI when I got back near the car at Games Loop/UWF Pensacola Florida.  It was great in the sugar sand of course.  Slid out on some fresh pine needles. Usually I could feel it slide and hook back up though.  I had to keep it weighted, more on top of the front wheel, kinda like riding a hardtail with a big fork up front.

As I slowly lowered the pressure, like half a PSI each ride, I had to ride on top of the front end less.  I worked down to 14 PSI.  That was just starting to feel more shock absorption at 14.  I stayed here a while, as I am concerned about breaking a bead and rolling the Knard off of the Blunt 35.

I settled at 13.5 psi, getting just the occasional bottom out clank.  I weigh around 200 lbs. No scale in the bus so not 100% sure.

Now I always break something at Stokes, Stokes has my number, you could say,  Stokes is pretty much all rock garden, even though rock gardens are usually my forte. My Stan's sealant was getting thin I guess.  I burped or punctured and was able to put the Knard/Blunt 35 up a few times, but ended up putting in a tube.
Back at a compressor, I removed the tube, added some Stan's and  reinflated and it has been good for a couple months now.

Wet rocks seem to be the Knards nemesis.  Particularly on technical rocky climbs, the Knard hunts around a bit, sometimes finding the wrong line, accentuated on a single speed.

Having a 29er+ up front and a weekend on a fat bike, got me jonesin for a 29er+ rear as well.  The Surly Krampus and the Carver Titanium Gnarvester, if you guys are listening :-) Lynskey said they could build me a custom one.  A guy can Dream.

My Lynskey was down for a while, when I got her back together, the bike's handling felt a little slower than I remember with the Knard.  The Ferrous has slightly steeper head angle, and maybe I got used to that.  I gave the 2.35 Ikon another try for comparison and it just worked better with my Lynskey geometry.


  1. Hi Jeffrey,

    I am about the get a pair of Kards + the Velocity Blunt 35.
    Did you have any issue to set them up tubeless?
    Thank you,

  2. Unlike a Stan's rim and many tires I have used, you can not use a floor pump. Make sure you have access to a high volume air source. I used the Velocity rim strip and valve and really like the how the rim strip stretches a bit for a more firm adhesion to the rim. While I do not think the rim strip needs to be set with a tube like Stan's, I still did to seat the bead. It took a little patience and perseverance, but it will seat up.

  3. Great, thanks a lot Jeffrey. I will get the rim strip from Velocity in that case. Going to build a Surly ECR with this setup.
    Greetings from the Alps!

  4. What are those handle bars? Thanks!

  5. Old Scott AT3 bars. Ned Overend used the AT4 version with a bridge between the ends in many races back in the day.

  6. I found on tight cambered trails that the Knard would wnat to travel up hill, making it a bit unsetting when the other side was exposure!
