knee puck wear question

So last weekend I hit a "new" track (Palmer Motorsports Park, but run backwards). There were two places where I was dragging knee a lot and when I got back I noticed that the wear on my pucks is in a different place than it had been.

Before, the wear tended to be on the leading edge of the puck... even with the pucks stuck onto the Velcro patch as far "forward" (to the inside of the knee) as they'd go.

New wear is much more towards the trailing edge and higher up on the puck.

Wondering why. Thinking it might be some combination of a little more lean angle, BP a little more off the seat, and not sticking my leg out as much "reaching" for the ground.

Any ideas?

I think you found the reasons pretty well.

Yep, more lean angle.

I typically don't stick my knee out until I'm near maximum lean, and then just enough to detect that angle. Otherwise it slows the bike down by 5mph or more!!!

Blunt honesty here....

If you didn't move the pucks on your suit, then you did something different on the bike. At the core, the track nor the direction makes much difference. Much like your tires, reading your pucks can tell you what you are doing or NOT doing on the bike. The trick is to figger out why and how.

Ask yourself (since I have been there). Do some of the corners "open up" better when running the other direction? If so... it could lead to more confidence in lean angle, earlier and more aggressive bp and throttle control. If not, it could have riders somewhat timid and have a different wear pattern than normal.

What do you think?


Assuming normal direct turn numbers
Lemme guess....

Turn 12
Turn 2
Turn 3
Post turn 8 (exit)
I could see turn 10 for you too

You touching down on any curbs? My left knee has a 2 angles on it from left turn 4 at Blackhawk Farms where I always touch down on the curb. Then the next left after that is my favorite "rail it freakin hard" turn where I get more lean angle than anywhere else. It's super easy to see the two different angles on my pucks, the only lefts at that track.

Otherwise, yeah everything csmith said.

Totally agree that it's me and not the track.

The two spots are Turn 12, which this way is a SUUUUUUper long increasing radius turn that is big fun, and Turn 7, the Laguna Seca-like one that climbs INCREDIBLY steeply going this way.

Turn 12... opens up the whole way around, no braking coming up, great sight lines and visual references, mo' confidence, mo' bettah. Turn 7... gravity giving you the warm fuzzies, ditto.

Turns 2, 3 and 8 are all high-speed kinks or nearly so both ways... not a lot of lean angle there.

Going this way is like NYST downtown: You spend more of the lap climbing.
