just sent what one?

60T is just waiting for wider acceptance of 36" wheels

Noodles/Liners can work for BC XC too.

Stans Podium wheel set:     1287g (29")

2 Pepi's Rokkline Noodles (the heavier enduro ones) with valves:  200g

2 Schwalbe Racing Ralph 2.35x29 Snake Skin: 1540g

2 scoops Stans sealant:  100g

________________________________________________________________

Total: 3147g

How about Pepi's Rokline (the yellow enduro ones) at 100 gm with valve per tire.  They seem very durable, even after rides with 0 psi because my rim tape wouldn't stick. And you won't have as much of a weight penalty.  The old red and new pink 3-lobe-shaped Pepis are even lighter, but have no idea about the durability.

Grasshopper/Dave, you have progressed towards enlightenment.

Pretty soon you will be bikepacking  ;-)

The  fit/advanced/or pro riders who ride uphill more and cover more distance (vs the  downhill strong/advanced/or pro riders who shuttle and uplift more) are also more efficient by wasting less energy (such as they brake less, lose traction less and schralp less) and are overall lighter on their tires (by that I mean, impact to the trail surface not just body weight)

the other trail users around here are walkers, dogs, runners etc. 

the North Shore is not a dedicated mtn bike park

I turn 60 this year. As a gift to myself (before the covid lockdown) I got a road bike, instead of an ebike, to go faster.

I can see "the trails are too crowded to be enjoyable" for some riders on the North Shore.  They are wanting to rip the downs on the popular trails, but there is already a train of riders ahead of them (I prefer jank and technical climbs, so it isn't bad for me yet). But jank, rather than flow, reduces the speed difference between user groups, so more jank or technical-trail-features that force a rider to use more body english, or to ride around as a form of speed chicane, could possibly reduce ebike problems.

the "cheater bike" term for ebikes is fun too

so also too bad

What bike shop carries ESI grips in North Van?

What about rear-wheel-traction? Not being as far forward on the bike might be beneficial for that purpose. Considering the kind of power pro-racers can put down, keeping the rear wheel from spinning is probably important.

You’re underestimating how great the effect chainstay length has on climbing traction.

YouTube Hill Climbing Dirt Bikes and look at how long the swingarms on those bikes are.

those hill climbers have far more power and torque than any cyclist, and are in near wheelie balance their whole run

the longer chainstay makes it easier to stay at the balance point, such as its easier to balance a baseball bat on your forehead than a pen, it damps/slows movements away from the balance point

I bet tall xc racers could benefit from longer chainstays too, because easier to modulate

Long front centre and slack HTA is not as good for flat corners where you need to extra weight the front wheel. 

XC riders corner while seated more too.

For the pinkbike showdown you refer to, only ~2 bikes have 69 degrees or steeper.

I have been experimenting with a Works angle adjust headset on an Element, going from 69 degrees to 67.5.  It wasn't as night and day as I expected, and since the bearings began to make lots of cracking noise I went back to the original headset and didn't die going over the bars. 

I think to make long and slack work, you also need a much grippier front tire, which usually means more rolling resistance (and slower overall)

Another thing you want to check is the spoke tension after a tire is mounted and pumped up. Those light Stan’s rims lost a lot of tension with a tire snapped onto the beads. Like 20 kgf lower. I’ve even measured a pretty substantial drop on ENVE rims.

I agree.  I couldn't believe at first when building up MK2 Arch (not the lightest Stan's rim), so tested with tire on, tire deflated and tire off and back to tire on and inflated, and the drop in tension was consistent.  Tire on and seated, but deflated was about the same as tire on and inflated.  With the tire off the tension was a lot higher.  The final tension I used, was what was recommended on the little Park chart, but for the wheel with an inflated tire. However, I began to notice small stress cracks around the nipples after a year, so now I build to the recommended tension with the tire off then add tension after I ride a bit if the wheel seems noisy.

I would gladly boycott Strava, but I use it as my ride log and to compare my times on various segments.  Is there a better alternative to that?  

Trailforks

I already use Trailforks but I didn't think it recorded times for trails or segments.  I don't care about my time, but I like to see them in aggregate and see if I am improving, especially on climbs since I am perpetually trying to get in shape.  :)

go to Leaderboard then My Results for your times on segments (although the segments might not match what you consider to be "the trail")

wow. what kind of dance and gymnastics do you do? serious questions.

Disco! Boney M Rasputin - missed the edge of the stage with a cossack kick during a goofy bar competition and tore my ACL* (still won though)

Parallel bars. Fell through backwards onto my head and got a bad concussion

* Uncle Dave would probably say I deserved it for being in any way associated with disco

For me, dancing and gymnastics are more dangerous, than biking or skiing

no love for 9 Point 8?

I made it and printed onto photo paper
Could be less ghetto by going to a  model shop and getting printable water transfer decal material, but the Tallboy decal is still underneath
